in 3D Modeling Design held by Firstwear
Contest Ended, Winner(s) have been selected.
Project Details:
We have a design for small wearable sensor that was to be worn on the wrist. We've had 500 testing devices produced and now we're looking to redesign it so that it can also be comfortably gripped in the hand. The internal specs will stay the same because we only want to improve the external aesthetics and form factor.
We're looking to start with conceptual sketches and then narrow down on 2 rough directions and then a final design.

Deliverables include: sketches, 3D rendered images, files for 3D printing mockups and final production CAD designs.

You should have experience with consumer friendly products.
Familiarity with electronics and rubberized materials is a plus.

The casing (and its incorporated device) is to fit in the palm of the hand. It is held there by means of a strap, much like a watch, but equipped with Velcro so that it can be easily adjusted.

The casing itself needs to be shaped so that it can be very comfortably held, hand gently closed. The shape is novel, and the material, attractive to the touch, may be slightly compressible as in rubber or silicone.
The casing should have two openings, on the on/off button, the other for recharging the battery (a phone recharger port).

The dimensions of the device to be encased are: 1 ½” X 1 9/16” X 5/8 “
Sample images of the current iteration have been attached.
understanding of the goals and objectives and familiarity with other devices within the wearable space
Don't Wants:
overdesigned and complicated to execute
  1. auto
Additional Information
The size of the device that needs to be encased within your designs is listed. The final design should be able to be worn on the wrist as well as held in the palm of the hand.

#14 Sense Sensor by Ridwan Sept
"Sense Sensor"
My design direction when I created this one is :
- Make the visual attractive, unique, futuristic, simple and ergonomic.
- Main material of casing is plastic LDPE (or another recommended material from mold supplier)
- With rubber seal so this is water and dust proof.
- Use M3 Screw (Qty : 4 pcs).
- On/Off Button make with Rubber.
- Charger Port (I forgot it because I do this projects in limited time, but if you want to pick me as the winners I'll add the charger port to this products).
- Another solution for charger port is use wireless charging method (this is more support for waterproof products).
- Why I make this products waterproof? Because this is will use in humand hand, that's many times contacts with water. So this features are meet the daily activities of the user.
To get the cheaper mold prices, we can make the case as family mold (with side cores) and the sealed rubber as family mold too). So in this case we need 3 mold "case, rubber seal and on off button.

ABS plastic or appropriate silicone can be used for moulding to achieve matte finish. Snap hooks aren't implemented yet since i'm not sure about the material you want to go with.

#11 conception by medmihaly
conceptional renders of the product. materails are not definitive - the rubber and metal - they are just for illustration. I didn't use Velcro, but if it's necessary it is possible to make a design that conatins it. feel free to share your opinnion about it.
thank you,

#10 Silicone Covered Wearable Device - Concept Design by Abbasi 3D-Services
Note: This is my public Concept for a wearable device and all rights are with me.
I sell you just the concept, because your price is so little. it is not enough to get the industrial files, no way.
When you like my concetpt and want to get it, you can pay for the concept only and work on the files alone, or you can pay me more to that.
I am a prof. designer and have my limit.
Best regards,
Mohsen Abbasi

See my Design, my concept design.
I wrote you that I sell just the concept for $480 here. You can not order more for this price, no way with prof. designers.

because in your last design I can not see any touchpart to the skin.
Thu, 02 Jul 2015 20:22:24 +0000
Has the systemt get touched to the skin?like some designes here? or the sensor is for movement.

I've attached an image of the 2 halves of the existing case that we wish to eiher enrobe or incorporate into a new design. the cavity of the case should be the same size if you are designing a new we can fit our electronics.please remember this device will both be used worn on the wrist and held in the palm.we prefer a plastic housing comfortably worn or held with the lowest profile.

Similar Contests on Cad Crowd

We are posting a contest for development work that specializes with human facial modeling, texturing, animation and 3D mapping in after effects for integration into HD video work. This work is to reconstruct a 3D facial model from a deceased celebrity whom we obtain plenty of photography of the individual as well as a generated preliminary 3D models from Face Gen and Face Shift in the animation requirements.
Designing a Business-Oriented Conceptualization tool: a 3D Cube to visualize market segments
We have designed a conceptualization tool using Powerpoint, which consists in a cube representing market segments and how a brand positions itself across these segments. Each of the 3 dimensions of the cube represents a way of segmenting markets (for instance geography, products, customers). The cube breaks down into many different smaller blocks along the intersection of each segmentation criterion. In other words, each smaller block (defined by a combination of product, consumer and geography) represents a specific market segment. Additionally, we have drafted a “cube within a cube” approach: you can zoom in on 1 specific geography and get a second cube, which will show market segments along three axes (product, customer and a new one: distribution channel). The design should integrate this “cube within a cube logic”. Please refer to the uploaded screens to better grasp what it means visually. The deliverable produced by the designer(s) using CAD will be used extensively by non-experts to build presentation-ready visuals in a business-oriented environment. The deliverable must meet the following requirements: - Possibility to highlight different segments with multiple colors in a flexible and user-friendly way - Possibility to visualize the cube from different angles - Possibility to easily change the labels of the different axes You can refer to the uploaded screenshots to better understand what the deliverable will look like. Important: we advise designers to focus on designing only a few visuals at first: slides A,B,E,F,G & 1 to limit the time they will have to dedicate to compete. As a second step, we will select one or two designers to produce the final deliverables, giving them extra context and information. After the contest is over, the winner may be proposed additional jobs around the project, in exchange for a competitive compensation.
NoGoer - 3D Printing friendly Design for Kickstarter Project
Designed a product which is planned on being launched on Kickstarter. Electronics are complete, but an enclosure 3D model needs to be designed so a prototype can be 3D printed. Finally, the 3D model would need to be create with draft, fillets, and other injection molding requirements.
Toy siren whistle modeling in Autodesk Inventor
Existing pneumatic mouth-blown siren whistles need a large volume of air at a fairly high pressure in order to produce a noise. Project Goals: Create a siren whistle model assembly (rotor, stator(s), housing) in Autodesk Inventor that that I can 3D print (I have Inventor myself, so I can modify part/assembly constraints and export STL for 3D printing) and I can experiment with the effect of changing constraints such as: different part/assembly sizes, number of rotor vanes, angle of rotor vanes, position and number of stator openings, etc. Ideally, the provided model with the default constraints produces a siren noise that uses less volume and pressure when blown through than existing products (such as those depicted at and on attached image). The model should also be moldable and assemble-able using conventional plastic production manufacturing methods. Provide constrained Inventor files upon completion. It is anticipated that reduction in size of the existing approach should produce the desired result. Higher pitched frequency than that produced by current commercial versions is OK. I've also included 2 photos of a: 1) stator/retention element (with round holes), 2) rotor and 3) stator/housing (red) from a "lip whistle" siren toy.
