Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If lens elements are made adjustable to correct tilting and alignment issues, then image quality is improved, but device complexity increases
Solution Approach 1:
The lens assembly is divided into fixed lens elements and adjustable lens elements. The adjustable lens elements can be independently positioned and oriented using adjusting channels, allowing precise alignment correction without making the entire lens system complex. This segmentation enables targeted adjustment of only the necessary components.
Solution Approach 2:
Adjusting channels are introduced as intermediary structures that facilitate the adjustment of lens elements. These channels provide guided pathways for moving lens elements into correct positions and orientations, simplifying the adjustment mechanism while achieving precise alignment without complex external fixtures.
2Measurement precision
If adjusting channels are provided for lens element adjustment, then alignment accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The adjusting channels serve multiple functions: they guide lens elements during assembly, provide adjustment capability for alignment correction, and can also serve as fixing structures once adjustment is complete. This multi-functionality reduces the need for separate adjustment and fixation mechanisms, thereby controlling manufacturing costs while maintaining high alignment accuracy.
Solution Approach 2:
The adjusting channels are integrated directly into the lens holder structure, merging the adjustment mechanism with the supporting structure. This integration eliminates the need for separate adjustment devices and reduces the number of parts, thereby lowering manufacturing complexity and cost while maintaining precise alignment capability.
3Manufacturing precision
If lens elements are made adjustable and then permanently fixed, then image quality is maintained, but assembly complexity increases
Solution Approach 1:
The adjusting channels are pre-formed in the lens holder during manufacturing, providing ready-made pathways for lens element adjustment. This preliminary preparation eliminates the need for complex adjustment fixtures during assembly, allowing workers to simply insert and position lens elements within the pre-designed channels, thereby maintaining optical alignment precision while simplifying the assembly process.
Solution Approach 2:
The adjusting channels are designed to self-align and self-limit the position of lens elements through their geometric constraints. Once a lens element is inserted into the adjusting channel, the channel's shape and dimensions automatically guide it to the correct position and orientation, eliminating the need for complex external alignment tools or procedures.
