Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an array lens with multiple parallel lens units is used, then light transmission efficiency is improved, but manufacturing variations cause deviations in optical paths and beam diameters
Solution Approach 1:
The array lens is divided into multiple independent lens units, each capable of being manufactured and adjusted separately. This segmentation allows for individual optimization of each lens unit while maintaining overall system performance, reducing the cumulative effect of manufacturing variations across the entire array.
Solution Approach 2:
Different lens units within the array can have locally optimized characteristics to compensate for manufacturing variations. Each lens unit can be individually adjusted or designed with specific optical properties to correct deviations in optical paths and beam diameters, ensuring consistent performance across the entire array lens system.
2Manufacturing precision
If correction optical elements are added to correct light paths, then optical precision is improved, but device complexity and component count increase
Solution Approach 1:
The correction optical elements are integrated with the lens units in a merged structure, where correction functionality is combined with the primary light transmission function. This merging reduces the need for separate correction components and simplifies the overall device architecture while maintaining optical precision.
Solution Approach 2:
The lens units are designed to serve multiple functions: primary light transmission and correction of optical path deviations. By making the lens units multi-functional, separate correction elements are minimized, reducing device complexity while maintaining the ability to correct manufacturing variations.
