Covid-19/Coronavirus Product Design and 3D Printing Challenge (open source designs)

in Product Design held by MacKenzie Brown
Contest Ended, Winner(s) have been selected.
Description:
With the outbreak of Coronavirus; testing, social distancing, and handwashing have helped prevent the spread of this disease. One area responsible for the further spread is frequently touched surfaces in offices, stores, and workplace areas (i.e. door handles).

We believe the Cad Crowd community can help prevent the spread by creating open-source product designs for public spaces.

The contest involves creating products that will be shared under a publicly downloadable open source license (Creative Commons). The goal is to develop designs that can be quickly and affordably produced with 3D printing and/or off the shelf basic components (i.e. pre-made parts that are readily available).
Wants:
Some product ideas include no-touch door handles, no-touch doorknob attachments for houses/senior living spaces, and no-touch faucets. These are just examples, and we’ll consider all new product concepts that are practical, affordable, simple to produce and can be easily cleaned (see attachment with product examples/ideas).

Please submit your design entry with images, a neutral file format (.igs, .stp, .fbx, .obj, .x3d, etc.) and a native file format if applicable (SolidWorks, Inventor, CATIA, Creo, NX, 3ds max, etc.). In add-on, please upload your entry as a downloadable file into our new CAD library so that others can view and download designs - www.cadcrowd.com/3d-models/new

Thanks for your help with slowing the spread of this disease in public spaces and please ask any questions in the comments area below. All participants that submit a high-quality entry will receive an additional 50 bonus points for contest participation. In addition, we’re aiming for corporate sponsorship to increase the value and number of prizes available for this contest.

Cheers,

MacKenzie
Additional Information
Hi All, thanks for the great entries! Will work through these designs with colleagues over the coming days and reply with feedback.

To re-iterate on contest goals: we want to create open-source designs that anyone can download, easily produce (3D print or create with commonly available parts) and use in public spaces. This means that all designs are currently downloadable by everyone (i.e. peers, companies, media, etc.) to immediately reduce the spread of COVID-19 and ideally save lives.

Please remember to read the description/evaluation criteria for consideration and submit your design as a downloadable file in the CAD library ( www.cadcrowd.com/3d-models/downloadable ).

To help with judging, we’ve enabled peer reviews (temporary) - we want your help short-listing the entries that you feel would be useful in the workplace. As a side note, the Autodesk Viewer ( viewer.autodesk.com/ ) is a great tool for viewing CAD files if you don't have compatible software. Please keep comments polite and professional to maintain a positive/creative environment. Send me a private message if you have concerns about derivative designs that seem to closely follow designs from other users without adding any substantial changes or value.

Open collaboration ( bit.ly/3dhVqrP ) for design entries is permitted if it’s mutually agreed to between yourself and the other designer(s). In this case, prizes would be split between participants and hopefully, we’ll get some extra sponsorship to make that worthwhile. *Note: Cad Crowd does not guarantee that design entries will prevent transmission of the novel Coronavirus.

#111 Hook Ring by cristianonishi
A simple hook can be quite usefull these days, so you avoid touching things as you can grab, push, pull or press things with a hook. Importantly though is that you always have this kind of tool with you and you simply don't forget it. Therefore the idea of integrating a hook with a ring comes in place. But it is not as simple as I first imagined, because of ergonomical problems. Only a ring normally doesn't work, because most of the applied power would hurt the fingers through longitudinal torque on the fingers or it would just rotate it without being able of applying any torque at all. Therefore it was necessary to adapt it with two other hooks on the lower side (palm side) so that you can apply torque in any direction you need it. In other words, the ring will not rotate and it will not hurt you, since the forces will distribute through the side fingers and the palm when you close the hand.
Design was also an issue for this project, because only function will not motivate people to wear it. For this reason I chose something that can be both masculine and feminine, but somehow young, as trends appear easier with young population.
It could be shaped in thousand other variations, but for this first proposals this not so complex and not so simple shape seemed fair for me. It's designed to be 3D printed with plastic materials. These shapes need a SLA, SLS or FDM with water removable support. The reason is that it must have some design appeal that motivates you to wear it. But this design will of course not be liked from everybody, but a small group of people that is open for this function and design.
I uploaded three versions, because as I asked some people about this project, I saw that people wear and use the ring as their subconsions tell them and not as it is best engineered. I printed some tests and some people told me that the first was definetly the best, but a similar group told that the version 3 is definetly the most useful, although some told that the hook should be in one or the other side. It's only because things like opening a simple door is an automatic thinking and we just do it without thinking. Therefore we should do it on the way we think is the easiest for us. Most of the time it makes no difference how efficient we do something, but only that we do it.
It must be scaled individually to fit on everyone's finger. They all have the basic size of 19,5mm of inner diameter. Specially the version 3 must be independently scaled longitudinally, so that it is around 10-20% longer than the finger, so that you don't touch the hook as you open the hand. Otherwise it would be useless.
My personal most usefull version is the first one, because I wear it almost during the whole day on the middle finger printed with 20,5mm and the opinion of most of the people is that I only have some fancy ring and don't know for what it is at first glance.

#113 No touch multi-purpose attachment by From_the_designers_bay
This model is of a very simple product which can just be placed permanently on a door knob or a faucet. It has a long projecting handle, by the help of which the person can operate the door or a faucet with elbow and thus no chances of contact of hands of a person with the doors and faucets. This product will be helpful at homes as well as public places and it is always better to have such a thing at public places. One more advantage is that the product, being open from the other side also the person can access the locks of the doors easily without any problem, also enough visual will be present for a person to access the lock. The product is easy to install and use, also the product can be removed at scheduled intervals and cleaned. One more thing that can be done with this product is that from one side it can be manufactured of standard sizes of door knobs and on the other side, the size of faucet due to this a single product will serve two purposes. Also the design is very easily 3D printable. You can always contact me for more details and ideas about its use and the development of this product.

#75 Infinite strile door handle by metinberkenis
I am working in a company that 80 employees works. Because of these numbers ı always clean the door handles or touching with somethings , but sometimes ı forget take something with me to touch door handles. In my design door handles are always clean owing to alcohol liquid with potential energy. The spounge that covered door handle is always full with alcohol. Pipes brings the disinfectant liquid to spounge cover that manufacturing with 3D printers and the liquid spreads into the spounge. Essipecially in companies this design will be so useful. Employees wont open the doors with dirty hands or wont bring some items to touch the door handles. Door handles always be clean owing to alcohol, spounge and potential energy. We can assamble the alcohol cover every door easily with two way stcikies or screws.

#79 Bagless 3D Printed Ventilator by James Zaremba
For a novel virus there is a novel ventilator! The operating principle can be seen in the diagram uploaded, the basic premise is that when the moving head piece is driven up the rack by the 2 motors there is negative pressure created in the chamber which draws in air and oxygen through the one way inlet valve. When the motors spin the other way and retract the head piece into the base the air in the chamber is forced out of the outlet valve (i'm sure many of you have seen on countless ventilator designs) into the patients lungs. The only parts that aren't 3D printed are the valves, DC motors and corresponding securing screws. I aimed to make this design as easy as possible to print and assemble, all that is required is plumbers pipe adhesive or a solvent based adhesive. The only parts that require gluing are the rack, motor brackets and valves. Unfortunately, I don't have access to a 3D printer so i cannot prototype it but I have attached all of the design files so I encourage anyone who is interested to have a go and document their results. This is the motor used https://uk.rs-online.com/web/p/dc-geared-motors/8347631/ and the mounting screws are 6mm long M3 Pan Heads.

#95 Door Handle by supplemental-design
I took the idea of something to avoid touching door handles. I haven't been able to 3D Print it yet to see how well it fits the human hand, or how well it fits and works with a lever type door handle.
The simplest and most obvious use is to hook door handles most commercial/business building have and pull them open. I went ahead and added a feature to allow for pushing as well as pulling, but I have safety concerns that a person could sprain a wrist if they don't adequately stabilize the wrist. To use it with lever type door handles, the tab type feature on one end can go on the top or bottom of the "stem" coming out of the door, the axis of rotation, using it as a lever to turn the lever type door handle. If I had my 3D printer unpacked, setup and knew how to use it I would like to have taken a picture of what I'm attempting to describe. It's symmetrical for maximum flexibility for various applications and people.

#109 Hand powered Ventilator - Updated by Muntazir Merchant
I have made some modifications to my previous design by adding an oxygen valve. The oxygen valve is a one way valve that allows flow of a fluid in only one direction. I have also added a butterfly valve in front of the oxygen valve to control the amount of oxygen being supplied to the patient. I have also added lofts for all the vents so that the dimensions can be changed easily to fit the required diameter of the pipes being used for the oxygen inhalation or exhalation pipe of the endotracheal tube.
Note: The variables of the design (such as Tidal Volume, PEEP, Oxygen % aka FiO2 and flow rate of inhalation/exhalation) must be set by a professional or an Intensive Care Specialist. Do not try to do it yourself, as any incorrect variations/calculations could lead to severe irreversible damage to the patients lungs and can also lead to death. Since this device provides a Continuous Mandatory Ventilation (CMV) proper precautions must be taken and the patient must be sedated. The device can be operated by any ordinary person once the variables have been set by a professional/intensive care specialist.

#114 Automatic Door Handle Sanitizer Pair by Waqar Qureshi
Construction
This pair consists of two same devices, one for the push side of the door and one for the pull side of the door, with the only difference being their actuating levers. They consist of an actuating lever, a spring, a 3D printed container body, a small piston and a cap for filling the sanitizer into it. [Translucent material is applied to the main body only for the purpose of clear depiction]. ABS is recommended as material, but one can definitely try other materials as per availability. Springs can also be used as per availability until it gets the work done. This makes it a flexible and DIY product.
Working
Pull Side
The initial position of this device’s piston (while the door is open) is about 6.5mm above the compressed position with the spring holding it at that position against the lever. When the door is closed, the lever is pushed by the closing of door and the piston moves to the compressed position displacing more than 0.5ml of sanitizer volume. This sudden displacement causes the device to spray sanitizer over the door handle.
Push Side
The initial position of this device’s piston (while the door is closed) is about 6.5 mm above the compressed position with the lever holding it at that position against the spring. When the door is opened, the contact with the lever is left, and the spring pushes the piston to the compressed position displacing more 0.5ml of sanitizer volume. This sudden displacement causes the device to spray sanitizer over the door handle.
Design Features
• Both the devices are attached on the door just above the door handle by any adhesive (or can even be screwed if there’s a possibility). Push side requires the “Hand” to be attached on the wall near the door as shown in pictures.
• Pull side has 4 different plastic parts + 1 spring. Push side has 5 different plastic parts + 1 spring. The parts among both sides are exactly the same except the springs and levers.
• The lever in both the devices have been designed to triple the mechanical force at piston by leverage.
• Both the levers have been given 3 mm extra interference to avoid any loosening in future.
• The spring for pull side must have a free length (here 24.5mm) such that it can keep the piston 6.5mm above compressed position.
• The spring for push side must have a free length (here 31 mm) such that it can keep the piston at compressed position.
• Though the spring mounting area can easily be adjusted in CAD to compensate whatever spring one can arrange. Recommended wire dia. of spring is ~1mm.
• Holes are provided for firm spring mounting.
• The lever holes (joining with piston) have been given an extra 2mm allowance to compensate the extra joint required to change rotary motion into linear.
• All the allowances suitable for piston wall, cap wall, pins have been applied in the CAD model already. Though one can adjust them according to their 3D printer device.

#116 Wearable sanitizer by Abdul Tanzeel
Hello there,
Although we try to avoid touching things and are trying to avoid contact with many innovative products, there is still a possibility that we may touch the infected surface by mistake.0
A person gets infected with COVID-19 by inhaling it or by touching the infected surface and then touching his/her face with the hands. Even though there are many pocket hand sanitizers in the market we might just forget to apply it from time to time as we haven't cultivated the habit of it.
I have a simple, silly, yet effective approach to the above-stated problem, A wearable hand sanitizer.
This device has a simple mechanism to provide the sanitizer with just a press of a button. there are no electric components the mechanism is purely mechanical and can be easily 3D printed. The device can easily be placed below the palm with the help of a belt or band. It can also be used with normal watches and fitness bands. The sanitizer can be refilled easily like an Inkpen, just dip the opening in the bottle and pull the slider back.
The device can be bent and printed as shown in design-2 for more comfort.
Hope this makes a difference !!!!

#126 Personal Door Opener by Sabhya
This is a portable and handy product used to access most kinds of doors and does simple tasks such as push buttons & lift bags without making human contact with the knob/handle/button/bag, hence avoiding the spread of germs and maintaining hygiene. The product is capable of making a huge difference in minimizing the spread of COVID-19. This is a very versatile product. An easy and cost-effective measure to manufacture it would be 3-D printing.
The photo is labelled to explain the functionality of the product.
A - This is where the user will HOLD THE PRODUCT. The curve present helps a third person to use his/her wrist to open the door once the product is attached to a doorknob or a door handle.
B - This part of the product is used to fit into a DOORKNOB. Certain measurements were taken to make sure that the product fits in most doorknobs with ease. Due to its unique shape, the jaws flex open to form a firm grip on the knob. The tread design aids in the process of giving an additional grip. After the Door Opener is attached to the knob, a lever-like action of the product will cause the knob to rotate and open the door.
This part of the product is also used to open PUSH DOORS.
C - This part of the product is used to PULL DOORS with handles. The space provided is enough to fit most door handles and pull the door with ease. This part is also used as a hook to lift any sort of bag or a similar application.
D - This part of the product is a simple point to PUSH BUTTONS such as an elevator button.
E - The given hole in the product is used to tie the product to your bags or belts or keychains and make it as handy and portable as possible.
F - This part of the product is used to access LEVER TYPE DOOR HANDLES. The pocket is used to grip the handles. The taper given in the pocket makes sure that different shapes and sizes of handles are gripped easily. After the Door Opener is attached to the handle, a lever-like action of the product will cause the handle to rotate and open the door.
The Portable Door Opener can further be prototyped and the design can be optimized according to the needs.

#127 Door Knob/Tap Hands Free Design by Auld Jocks Design House
The attached design is intended for use on door-knobs and spherical or cylindrical tap heads of 50-
74mm diameter (standard door-knob sizes range from 60.3mm to 69.9mm). This is demonstrated in
the attached renders and design and testing notes.
This design was created as there seem to be a wide range of solutions in place (or even proposed in
the competition already) for modern cylindrical door handles and slightly more modern tap designs.
This design aims to provide a solution for 'traditional' door-knob and tap designs while maintaining
usability for both able bodied and disabled, less-than-able and elderly demographics.

#128 No-elastic Mask by Auld Jocks Design House
The attached design is intended for attachment with an article of clothing or otherwise to create a
mask. The sizing of the holes at the ends are designed so that cloth inserted through them are not
easily removed through general use. This design was created after a conversation with a friend,
currently in Madrid under lock-down, who found it difficult to source materials that would allow the
creation of a makeshift mask after off the shelf masks sold out.
This design would allow users to use any article of clothing, or otherwise, as a mask. For example (as
the surgeon general recommended) a t-shirt could be used when folded. The ends of the t-shirt
could then be threaded through the holes at either end of the design until it is taut against the users

The design can replace existing handles. It fits over the square bar of existing lock mechanism and stay in place with 2 set screws. Its flat and broad design makes the pressing down action with the elbow easier and it's design is also far enough from the door to allow hooking of the arm to pull the door.

#21 No touch money holder by Backflipper33
Money is one of the most touched and dirtiest things in the world, by eliminating touching the money it lowers the risk of contracting the virus. For example, everybody is buying toilet paper but when they go to pay the payment in cash and they get change back, however that change could have been handled by someone with the coronavirus which is why I propose a simple solution, not touching your money, put it in this container and let all the money that is needed is handy without it actually touching your hands.

Hi everyone, please check out entry number 116. I have an interesting approach to avoid the stated problem. Obviously always open for suggestions and improvements.
And also the files with numbers are just image, I put the wrong software name there but the first two files are 3D models.

Hey @paulbaker, hopefully several community members are considering designs in the ventilator/accessories space (one of the uploads includes a valve). In addition, the ventilator space has good traction and the sites All3DP.com, 3DPrinting.com, and 3DPrintingIndustry.com cover a lot of those active initiatives.

A majority of the community designs focus on slowing the spread of the virus in the workplace and public spaces, which is a space lagging in design options. Inevitably, people will need to go back to work and visit public spaces. Prevention/slowing the spread is the goal and a lot of these designs will help people as they re-enter the workforce.

Fri, 20 Mar 2020 05:21:19 +0000
Please! stop sending ideas foolishly! better dig a little deeper, do research, and then propose! not that it seems that you want to take your old models out of the closet! xD It's design! please gentlemen! if a logo can take more than a year to think about it! Okay it should be fast but the contest has plenty of time to do research and come up with substantiated ideas! well I think so! :)

Animal (and other) themed kettlebells
This is a competition to design animal (and other) themed kettlebells. It is important that there are no sharp edges and no protruding elements that could cause injury or get stuck on clothing. The design will also need to allow for our logo being evident on the back of the kettlebell. Whilst the logo has been attached, the designers are free to adjust it in size, position, and proportion as they deem suitable. The size needs to be consistent with a normal sized competition kettlebell, which is easy enough for people to look up but as a rough guide: Handle Diameter: 33MM. Distance Between Handles: 123MM. Base Diameter: 140MM The actual design can be representative or a bit cartoonish, depending on the aspirations of the designers Nominated animals include: A lion, leopard, elephant, rhino (all obviously flattened down in their contours for safety), shark, eagle, dragons, snake, scorpion, crocodile, bear, wolf, Tyrannosaurus rex, Sabre toothed tiger, spider This list is a guide and designers are welcome to choose other animals or themes I do not require any primates and do not require skull designs
