Control Housing

Project Overview

Project Overview:

Create a variable-driven control house to adapt to variety of in-vitro lung studies.

My Personal Duties:

Designed control housing structure
Used global variables to vary parameters to make design dynamic
Designed and installed heat sinks (iterated dimensions, countersinks, counterbores and drill depths)

Adapted design to create entirely new box in under 2 minutes.
Was able to redesign a similar box with entirely new dimensions (length, width, height) and had the panel sizes, hole distances, screw placement, and assembly auto-adjust

Goal: make the system as modular as possible for future teams to adapt to their own projects.

Solution: Use extensive variable tables with detailed explanations to allow for easy knowledge transfer

Skills:

- Extensive use of variable tables and formulas in Onshape to construct designs

Features of Design:

- M6 grid on bottom to attach internal devices

- Symmetrical hole placement for support brackets to make panels exchangeable

- Created two angle brackets (as shown above in right pic), mirrored for simplicity

Original design: No symmetry in panel cut outs due to only one angle bracket design

Final design: Hole pattern is symmetrical on each side with two angle bracket designs (one mirror part)

Errors:

Originally had too much clearance and heat sinks popped out
- Lowered diameter variables for less clearance
Heat sink was not guaranteed to be centered
- Added chamfer for more centered fit
