Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light-emitting elements are integrated into the optical module, then the illumination capability and functionality are improved, but the module size and complexity increase
Solution Approach 1:
The patent combines multiple light-emitting elements (first light-emitting element and second light-emitting element) and light-receiving elements into a single optical module that shares common structural components including the substrate, housing, and optical coupling mechanisms. This merging approach enables enhanced illumination capability through multiple light sources while avoiding proportional increases in module complexity by utilizing shared infrastructure.
2Adaptability or versatility
If light-emitting and light-receiving elements are integrated in the same module, then design freedom is improved, but operational independence deteriorates
Solution Approach 1:
The patent segments the optical module into distinct functional units: light-emitting elements (first and second), light-receiving elements (first and second), and their respective control circuits. Each element can be independently controlled and operated, maintaining operational independence while achieving design freedom through their integrated arrangement within the same module structure.
3Adaptability or versatility
If the optical module size is increased to accommodate more elements, then the functionality is improved, but the compactness and integration efficiency worsen
Solution Approach 1:
The patent arranges light-emitting and light-receiving elements in a three-dimensional configuration on the substrate rather than simple linear expansion. Multiple elements are positioned at different locations and orientations, utilizing vertical and lateral space efficiently. This dimensional arrangement enables enhanced functionality with multiple light sources and receivers while maintaining compact module footprint through optimized spatial utilization.
