Motion tracker unit with holder

Contest Ended, Winner(s) have been selected.
Description:
We are looking to develop product design drawings to be used for manufacturing of our motion tracker unit, which will be launched for a fitness center chain, for tracking use of exercise machines.
The unit will house our own electronic module and battery, so the design shall result in the required 3D production drawings for plastic molding of the unit housing (stp or dwg file format), which will be in two parts (top + bottom), and a matching holder.

Detailed descriptions (dimensions and considerations) are enclosed in a separate document, to be considered as guidelines with some freedom for the designer.
Wants:
Need to meet the technical specification attached, and designs will be evaluated based on esthetics and functional cleverness.
Don't Wants:
I don't want an exact copy of the suggestion in the attached document. Feel free to make a pleasant design while maintaining the functional properties.
Company Logo:
Yes
Software:
  1. .STP - Step 3D CAD
Additional Information
12.05.2017: Update on contest - We realize that demanding production drawings for the molds to produce the plastic parts forming the motion tracker unit and holder is too much. So we will only require 1 set of drawings, for the 3D design of the product. I have updated the description below (under 02.05.2017 update).

Apart from that, we have now finally given ratings to all contributors, and nominated what we think are the best overall designs so far, with emphasis on visual design as well as function.
We are a small and fairly new technology company, with a lot of activity so apologies for late feedbacks, answers and ratings - we just have a lot to do running the business as well as developing new products. Thanks for all inspiring contributions so far, and I shall look forward to seeing some further developed designs next week!!

03.05.2017: One tip regarding the "push button". As it may compromise the integrity against water ingress to introduce a physical button as a separate part/component, it is possible to achieve pushing ability on the center of the top section introducing a circular zone with a slightly thinner wall thickness, and with a centered pin on the interior side which will operate the switch on the PCB. The top section surface can then be completely smooth.

02.05.2017: Updated and uploaded revised requirements file. Mainly document structure and dimensions update. You should note requirement 0021, which will give constraints on the design for keeping the motion tracker in the holder:
[MT3001-REQ-0021] Retaining Motion Tracker in Holder
The Holder shall keep the Motion Tracker inside the Holder when applied of forces at least 5G.

The manufacturing process of the final design will be molding of three plastic parts (upper + lower part of the tracking unit and the holder), not 3D printing.

We want 1 set of drawings:

for 3D design of the product (including all dimensions with engineering units)

1. detailed view of each of the three parts separately
2. assembled unit
3. unit inserted in holder
4. Plus for adding design for the interior and clever solutions for 'pushbutton functionality' without physical pushbutton, no holes in the housing for tracker unit, light indication facilitated using thinner wall thickness in center of top part (in PB function area), and only screw hole in holder.

#1 Enclosure Concept A by Decker
Quick questions, for your contest. I see you want detailed drawings and everything kind of figured out for this contest and that's fine to ask. Just want to know a bit more about the application. I see a o-ring to keep out moisture. I was thinking maybe a soft rubber button in the center of the unit to provided function and possibly a light tube to illuminate that indicates Blue tooth and battery level. Do you require threads? or could this item be a snap fit? The twist lock in place, why are you considering removing it? Just some questions I have...
Jamie Decker / www.the3rddim.com I will be happy on request to provide a 3D view of this item in A360 if you like..

Gents, first og all thank you to everyone for your contributions to the contest !!

We are overwhelmed with all the entries and different designs sent in by you. The contest is now finished (as per 26th of May), however we have not yet concluded on the winning design.

The entries to are reviewed and rated, the remaining ones from to are still in review. We will however focus our work on the improved designs that we have already commented on, but will still be open to single entry designs.

I really want to do justice to all contributions, and take some time to review in detail, this is one of the reasons that ratings and response has been a bit slow on our side.

Nevertheless, we are in dialogue with a production facility which will manufacture our tracker unit, and the winning design from CadCrowd contest will be the design sent to fabrication (which will be one more process with possible adjustments to facilitate serial production).

So, I will get back to you with the final decision and reward for winning design, please be patient a little longer.

BRgds,

As for Pablo Gosso's idea, I 2nd that ...
Securing the unit via Nd-mag would be my first choice for this particular application. It would drastically cut-down tooling costs.

Hi Pablo,
Thanks for an interesting suggestion. This has been considered, the problem with this is that using a magnet will impact the radio communication between the tracker and our gateway, so this was ruled out as not suitable. But apart from that you are correct.
As primary fixing we will use double-sided adhesive tape, and screw holes are just as secondary solution if not possible to glue.

Hi Preben.

One question Instead of Holder and screw would you be willing to use Neodimiun Magnets?. It is just and Idea that I ould like to try and according to specs they a hold 5g. Plus you will be decreasing mold/tool budget?

Hi STL,
you are right, apologies. Pls see below.

1.Mounting holes on PCB with location are missing , we require those for designing lower shell.(Mounting Boss).
>> The PCB is still under development, so exact location is not so important, however the principle can be shown (we can even adapt PCB to suit your location of mounting pins.
2.Location & no. of LED lights on tracking unit for thin area on holder for visibility of LED lights
>> The best would maybe be a semi-transparent material which will show the light shining through the plastic. It is not necessary to have a very clear view of the light, only a "glow" is sufficient. However I would suggest LED should be located centrally on the top.

Hi STL, the top and bottom will not be same and need different mold, that is correct. Initially we thought it might be possible, however just disregard previous comments and questions related to using same mold for top and bottom.

Seems you are correct related to the RAL9003, the initial color was in different coding from our graphic designer and using a conversion tool online suggested RAL9003 to be the closest match in the RAL color coding scheme. It really is not that important for the product design drawings at this stage - pale grey or white will do.

Trust this clarifies.

Hi Preben,
Kindly clarify following points,
If top & bottom shell will be threaded then the mold will not be same.Even if any other joining method is used the bottom shell will have mounting boss for PCB so the molds will be different.
RAL Color mentioned is RAL 9003 which is signal white & not grey as mentioned in your document,
Mounting holes on PCB with location are missing , we require those for designing lower shell.(Mounting Boss).
Location & no. of LED lights on tracking unit for thin area on holder for visibility of LED lights.

Hi STL, the gap between holder and tracker unit is intended to pry the unit out from the holder using e.g. a screwdriver. It should be sufficient with approx 1mm gap.

Hi Samadoni,

the PCB is also under development, so this is not concluded I'm afraid. However, the button/switch will in any case be in the center. Will post an update once this is ready.

Hi Preben,

A drawing of the PCB outline with dimensions would help a lot, especially if it shows:
1) Number and location of the LED's, & button.
2) Fastening holes/notches locations.

Hi Ghufran,

Thanks for your question. The manufacturing process will be molding of three plastic parts (upper + lower part of the tracking unit and the holder), not 3D printing. We want 2 sets of drawings, one for 3D design of the product (detailed view of each of the three parts separately as well as assembled and inserted in holder), and one for manufacturing of the molds to produce the product (if possible to use same mold for upper and lower part of tracking unit that's great, and one for mold to produce holder).

I will add this into the description of the contest.

Thanks again,

Preben
