Further development

CAD model- Points to improve

From the CAD Model, I discovered a lot of problems, mainly related to assembly and the structure, to make it a more usable product, I have to refine more details.

CAD model- Improved details

From my last design, i improved the details such as i added the base to hold the motor, i made a hole to fit in the motor head. I also made small fences to keep the phone in there without falling out, the edges have also been rounded for better using experience. However, how the parts will be connected will still need to be figured out. As well as how the power will work more elegantly.

Refine Details/ Structure/ Power system

I decided to use a DC motor for my design, however i had the choice to connect the motor to an arduino board or directly to a battery box, since it's a portable device, as well as the form consideration, the battery box is a better choice.

At the same time, another problem emerged, what is the best way to change battery ?

What is the best way to change battery ?

The Piano hinge doesn't seem to work because the width of the battery box.

Doesn't fit at the back. Perfect here, but how to change the battery ?

Battery Box

Groove for the magnet

Hole for reaching the switch

Instead of having two sticks to be the axis of the rotaion, i think using a piano hinge will be better.

3D Printing test model

Visualization of the device in use.

I tried to make the shell and the battery pack rotate around the axis, i discovered that my previous perception was wrong, this mechanism will work.

I put two 2 cm stick into the groove, and i will stick the battery box to the shell. Which will make it rotate.

But another problem emerged- how would the sticks fit in? It would be hard to assemble.

Experiment drawings with the hinge.

Groove will be made to fit in magnets.

This need to a separate part

Edges will need to be rounded.

There need to be a small fence up to prevent the phone from falling out.

This hole will be cancelled because the battery box will not need a wire.

These materials will need to be removed for putting in the battery box.
