Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If optical modules are assembled with separate primary optical elements, then manufacturing flexibility is improved, but positioning precision and assembly time deteriorate
Solution Approach 1:
The patent merges multiple separate primary optical elements into a single integrated primary optical element that serves multiple light sources. This integration ensures precise relative positioning of all optical components while maintaining manufacturing flexibility through modular design of the complete optical module.
2Measurement precision
If multiple separate optical modules are used to achieve high resolution, then image quality is improved, but system bulk and complexity increase
Solution Approach 1:
The patent segments the optical system into multiple optical modules arranged in a matrix, where each module contains multiple light sources and optical elements. This segmentation allows high-resolution imaging through coordinated operation of multiple modules while managing complexity through standardized module design and integration.
3Manufacturing precision
If optical components are precisely positioned for clear imaging, then image quality is improved, but assembly time increases
Solution Approach 1:
The patent implements preliminary positioning features directly integrated into the optical components, such as positioning protrusions and recesses that automatically align components during assembly. This preliminary action ensures precise positioning is achieved as part of the standard assembly process rather than requiring separate precision adjustment steps.
