Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light receiving elements are used to achieve wide-angle field of view, then the detection capability is improved, but the mounting difficulty increases
Solution Approach 1:
The patent combines multiple light receiving elements and optical separating units onto a single base member, integrating what would otherwise be separate components into one unified structure. This merging approach maintains the wide-angle detection capability while eliminating the need for multiple separate mounts, directly resolving the mounting difficulty issue.
Solution Approach 2:
The base member serves multiple functions simultaneously: it holds the light receiving elements, supports the optical separating units, and provides the structural framework for the entire optical system. This multi-functionality reduces the overall component count and simplifies assembly while maintaining all necessary detection functions.
