Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic part is disposed between the laser box and the optical element housing to avoid safety issues, then safety is improved, but cost increases and additional dustproof materials are required
Solution Approach 1:
The patent merges the laser box housing and optical element housing into a single integrated housing structure. The laser diode is mounted on a laser box that is directly coupled to the optical element housing, eliminating the need for separate plastic parts between them. This integration maintains safety while reducing structural complexity and the number of required dustproof materials.
