Good day,
I'm a mechanical design engineer for over 10 years and I specialize in product design for small
consumer electronics. Current and previous projects include sensor based wrist devices, HRM
and pedometers. I have worked on projects with bluetooth capability, vibrator, LEDs, with LCD
displays...etc.
Below is my proposal:
The current BLE (bluetooth low energy) size in the market is LWD= 24 x 8 x 2.5mm so I'm
estimating around 30mm-cube size of the device. If I can squeeze it to smaller size after
layouting the other components, then would be preferable.
- I'll find existing lithium ion battery that's appropriate to the size. You'll have to supply the
battery capacity rating.
- There's a 10mm diameter specs of a coin vibrator that we can mount on the case and
connect to the PCB via wire or we can use a small flywheel type vibrator.
- LEDs can be mounted on the PCB and be located to a translucent window of the case
for the visual requirement.
- I can send a list vendors for the hardware/ plastic molding company
- metallic components such as vibrator must be located away from the antenna location
of the BLE.
- I will create 3D simulation of the mechanical parts & PCB outline and can submit in
parasolid/ stp/ iges formats for 3D printing requirements or you can advise the format
prefered.
