Mechanical Design - Watertight Locking Mechanism
To solve the issue of protecting the electronics from water damage from the external water body, several locking mechanisms were explored, connecting the middle interface (i.e. spectroscopy chamber and internal water flow), the bottom interface (pump and mesh) and the top interface (pad and flotation devices). This was explored in a manner which would ensure no water would flow between the connecting parts. Below is a rendering of the chosen locking mechanism:
The above part was meant to serve as a prototype, where a latch from the above part would lock under a solid extrusion in the bottom part, similar to a tupperware container. Based on this prototype, the locking mechanism would be placed at three calculated points around the circumference of the entire Lilypod, for each interface between connecting parts (i.e. three for each interface).
This prototype was sent for 3D printing to be tested. Check back on the outcome of this test!
