Motion tracker unit with holder

Hello again gents!
My final comment to this contest, as we have now announced the winning design. It was a difficult task to choose between so many very different good designs, and a learning process for our part. So many inspiring and interesting designs to go through. Well done everyone, and thanks for participating and submitting your ideas, it has been a pleasure and a lot of fun! See you next time, and keep up the creative spirits!

Note: Not sure why some of the design pictures turned up in my message, pls disregard, this is not the finalists.

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.

To the winner Congrats!!

Hi Preben,
Please rate the designs.

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?

Pablo

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.

Hello preben,

Thanks for the reply, but you have not clarified our last two points.

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,
Refer figure 2 in the specification sheets attached.Any specific requirement for the gap between bottom of the motion tracker unit & the holder.

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.

thanks for the description, i am working on it.

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

hello,
kindly confirm

as far i have understand you only want drawing for manufacturing, or you need model for 3d Printing as well?
