This consumer product is an accessory that provides enhanced usability to mobile phones and tablets.

The latest design of our "Band" is two parts:
1. Round Base that attaches to the back of the phone (made from a low-friction polymer like polyethylene)

2. A "band" that overlaps with the Round Base (1) and rotates/spins around it. (made from polyethylene over-molded with rubber to provide elasticity to the top band part)

The rubber part of the band elongates so that an individual's finger can be placed underneath the band and above the base. The elasticity part is important so it can accommodate different finger sizes.

The product allows users to hold the phone more securely.

Our current challenge is the design of the "Band" (2). This is where we need the help.

As shown in the attached STL file for the Band, there are two circles on either side of the flap that holds the finger down. These circle were put there to provide some added elasticity to the rubber piece.

While it does functionally work well, the current design does not look durable or very elegant.

We'd like to rethink the band design to make it look incredibly user-friendly, allowing the band to stretch upright to accommodate different finger sizes, while being functionally superior to the current design.

Designer will need to provide STL files for my prototyping company to be able to work with.
Looking for:
1. the most aesthetically pleasing design
2. One that considers usability (user sliding in their finger and feeling secure)
3. Understand the implications of tooling design -- we don't want to have to make an injection molding tool that is massively expensive due to a complicated design.

Hello Everyone, thank you so much for participating in our contest!

It was a difficult decision, with all the great entries, but we selected two winners that we felt best matched our criteria.

Thank you once again for taking the time to join in our contest.

Hi PJCAD, i will message you too, but at this time, i dont have other formats available right now. Only STL. Hope you can find a way to open them!

Dear MAS,

I would like to take part in your contest, I just have some problems with opening your STL files. Could you please upload parts to the attachment in other formats than STL?

Thank you in advance,

I have just uploaded the "base" STL. I did not realize that I had not included that in the original STL files.

Here are the parts explained:

## Band ##
HEB v2 rigid - The rigid part of the "Band"
HEB v2 - The soft/flexible part of the "Band" (The rigid part is over-molded with rubber to make this stretchy component of the "band")

## Base ##
Base X4 - The part that attaches to the phone. This part is inserted into the "band" through the side opening.

Thanks for your entries!

For ratings:
2 means good design, but not likely feasible
3 means better design, and possibly feasible
4 means better design, and very feasible
5 means great design, and feasible

Industrial Design of a Hand Pulse Detector
We are looking for a industrial design (outlook) of a hand pulse detector. This device will consist of the following. 1) Two metal plates on the device that will come in contact with hand when grip on it. This will form a closed circuit between the plates and thereby detect the electrical pulse from the hand (refer to attached for the existing device). Ideally the area of each contact surface of the metal plate should be more than 2000 square mm. 2) A micro USB port for charging the battery. 3) Power Indicator 4) ON/OFF switch. Internal design of the device is not necessary but must cater enough room to house the below 1) 1500 square mm X 1mm (thickness) PCB 2) 750 square mm X 4mm(thickness) battery. The design shall be in 3D CAD.

The ROBERT project
We would like a fresh set of eyes on our device ROBERT, a rehabilitation robot that release healthcare workers of heavy and continuous lifting which can cause physical strain and pain in the back, loin, wrists and shoulders. We aim to optimise rehabilitation through more frequently and prolonged exercises which can result in fewer complications and a faster retrieval of a patient’s strength. See more at www.myrobert.com. The current look is a mixture of many components comming together which does not result in a uniform design. Further we whish to incorporate a new robot arm, made by the company KUKA, the LBR iiwa version, https://www.kuka.com/en-de/products/robot-systems/industrial-robots/lbr-iiwa. This will later come in a MEDtech version, similar in use but in white and with a small change to the interface base. CAD data of the industrial version can be used for this design, change is that wiring will come out of the bottom of the medtech version and not the sides like the industrial version, so completely round in base instead of the small square thing on the side of the industrial version (so no visible wires). The industrial version can be downloaded here: https://www.kuka.com/en-de/services/downloads. It is the "LBR iiwa 14 R820" found under division "KUKA Robotics".
