Locking Mechanism Design for Consumer ProductBlind

Contest Ended, Winner(s) have been selected.
Description:
We are looking for a locking mechanism for our upcoming product that is simple and minimalistic, yet very robust in how it locks the two pieces together. When locked there will be lateral stresses forcing the pieces to slide apart. We want there to be virtually no chance of the pieces coming apart by accident while locked, and the mechanism must be simple and intuitive.

Items that must reamin the same are the length and width of the objects. Enjoy full freedom to change the trapizod shape.

Please refer to attached images for some of our previous ideas. These are simplistic, but they are either not aestheticly pleasing or they do not provide a reliable lock while the product is in use.

We have uploaded 4 different file types because we wern't sure what your preference would be. Please also take a look at the attached images to see the other mecanisms that we have designed thus far. These are the ones that we like for simplicity and minimalism sake but they are not the most effective or intuitive.
Wants:
Simplicity, minimalism, effectiveness of lock, intuitive design
Don't Wants:
Ideally, the mechanism would be internal or along the long edge of the pieces. We are not looking for something with various other pieces that will be needed to be manufactured.
Software:
  1. Autodesk Fusion 360

#1 Press and Twist by Duncan SmartEng
This design uses smooth, curved holds to guide both pieces into firm contact.
The only way to disengage both members is to twist.
I would shorten the grips for the actual design to ensure they can fit into the slots, but this is a fair representation of aesthetics and function.

#5 Aérospace inspired hidden lock mechanism by BuzzBen
This concept shows a simple design inspired by current aérospace technics for a sturdy link.
Geometry allows easy molding and hidden locking mechanism keeps a clean look in both assembled and disassembled configuration for a very intuitive Assembly experience.
Simple 3 parts design, 3rd part is a reliable Standard part I used in the past.
Dissassembly required force is adjustable (at assembly) within a range from virtually 0 lbs to 5lbs plus friction in one degree of liberty. Other 5 degrees are fixed.

#28 Slide Lock revision by kspeedy28
Hello, I have uploaded a revised version of my earlier design. You had mentioned concerns of dried paint clogging the mechanism, so I moved the release lever under the main body (I could also move it to the very bottom, but was not sure if it attached to something). To release simply pull the lever down with the tip of a finger.
The mechanism should now be protected form paint raining down on it, and the pin movement distance has been shortened, so less pressure is required to open it and increase durability/life expectancy.
I resubmitted it because I was not sure if you saw the revision. Thank you.

#31 Lucking Mechanism Design - by Adriano Ordoz Barissa by Adriano Ordoz Barissa
My biggest concern in this project was to get a simple solution that would make the final part easy to manufacture.
I am an injection mold designer and have carefully analyzed the parts in order to design a moldable part.
The locks and their operation are very simple, just observe the drawing to understand.

Howdy, Everyone! We would like to thank each of y'all for your work in helping us to design the best possible locking mechanism for our product! There were some incredible designs that really were innovative, minimalistic, and simplistic. We would like to congratulate RBL Designs on being chosen as the winner and for his help along the way!

Thanks again and be on the lookout for future contests from us!

So you want to design an attaching system to join different brush heads to a common handle. Also could you please tell if the brush+handle device will be manually operated or by a machine. Also tell what are you going to apply with the brush, whether a powder/oil/paint etc. Thank you.

you left a space between the handle and your locking mechanism
must this area be free?

does it have a lot of going in and out?
or you want to make the part in its place for a long time or for product life

Howdy guys,
So we do not have a hard number or unit for the force applied that it needs to withstand. With that being said, this is a paint brush head, so think of the force that is applied to a paintbrush while you are holding it at an angle. We want it to obviously be able to withstand that force with possibly a safety factor of around 3 or 4, just to ensure that there is no possible way whatsoever that the brush will accidentally pop out of place while painting. Please let us know if you have any other questions. Thanks!

It would also be most helpful to attach a basic sketch of the forces directions. There are to be 2 things to consider, the force required to attach and disconnect the 2 pieces together, but also the eventual force or stress when using the assembled tool. We can design an attachment that fits the first set of force but that might not be appropriate for the second set of forces/stress when the tool is being used. We also need that to consider mechanical clearance between the 2 parts. Thanks.

It would be really helpful if you attached a similar product to the one you want. just so we don't get lost.

Howdy All,

The product is a painting tool and will be made of injection molded plastic, so the forces shouldn't be that great. Honestly, I'm not completely sure what they'll be, but lets just say that its somewhere around 5-7 pounds at its maximin that will be trying to force the pieces apart.I'm working on verifying payment. Sorry for the holdup on that.

Thanks!

But, as optibild said we need its application and forces involved to solve it better.

One World Bracelet
We are designing a silicone bracelet that will consist of 14 equal-sized, interconnected sections. 7 of the bracelet sections will hold a small amount of water from each of the world’s 7 seas. The other 7 sections will contain small amounts of soil from the world’s 7 continents. The idea is that wearing a bracelet that contains samples of water and soil from around the world will make people feel more globally connected. The 7 sections that contain soil should be a light shade of brown and the sections that contain water should be a light shade of blue. We are open to each designer’s initial suggestions for specific colors to use and will provide feedback after receiving the initial designs. However, we would like both the brown and blue sections of the bracelet to be opaque (i.e. - non-translucent). Additionally, we would like to see two versions of the bracelet in all initial submissions…one that has the 7 sections of water on one side and the 7 sections of soil on the other side of the bracelet. And in the other version we would like to see alternating sections of soil, water, soil, water, etc. We will eventually have different sizes of the bracelet but for the initial design we can use a “medium” inner-circumference size of 7.5” (19 cm). We are looking to have a 3D CAD rendering for prototyping. We welcome feedback and submissions from designers who can suggest approaches for producing a bracelet like this that will need to have small amounts of water and soil injected into the bracelet sections at some point during or after the initial manufacturing process.
3D Modeling and Roof Design
I would like an exterior and roof designed based on my floor plans. Project MUST be done in Chief Architect. Looking for a modern style home, shed roofs, similar to the contemporary home on our website http://www.inartifex.com/#!untitled/zoom/cqxa/image1ido Material can be a mix of stucco, board and batten, limit the use of stone as the home is budget conscious. Feel free to be creative. You do not need to use the existing material etc.
Angled Keyboard Slide
The design requires a clean simple method with minimized parts and manufacturing costs. Product is low volume, 250 to 500 pieces per year. We are interested in minimizing capital tooling costs. Design challenge is to design a keyboard slide platform that sits at a 32.5 degree angle (see attached documents). Keyboard slide needs to easily lock in upward position when not in use, and needs to easily be released and slide downward when in use. The keyboard slide is on a cart platform, so when the cart is being moved around, if it gets bumped, we do not want the keyboard slide to dislodge and slip into the down position.
