Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional assembly methods with solder and separate components are used, then device flexibility and ease of assembly are improved, but assembly tolerance and angular error increase leading to image quality degradation
Solution Approach 1:
The lens unit and image-sensing unit are integrated into a single module assembly, where the lens holder is pre-aligned with the image-sensing component. This merging eliminates the need for separate alignment steps and reduces cumulative assembly tolerances while maintaining ease of manufacturing through modular design.
Solution Approach 2:
The lens holder and image-sensing component are pre-assembled and pre-aligned into an integrated module before final installation. This preliminary action ensures precise angular relationships are established upfront, preventing subsequent alignment issues and reducing the need for complex correction algorithms.
2Adaptability or versatility
If multiple camera modules are combined for stereo or 3D imaging, then functionality and application versatility are improved, but combined angular error and algorithm complexity increase
Solution Approach 1:
Multiple lens units and image-sensing units are integrated into a single camera module with a common holder frame, ensuring consistent alignment references. This merging reduces the cumulative angular errors that would occur with separate modules while maintaining versatility for stereo and 3D imaging applications.
3Ease of manufacture
If solder and adhesive are used for electrical connection, then electrical connectivity is achieved, but position stability and angle precision deteriorate
Solution Approach 1:
The electrical connection structure is segmented into distinct alignment features and connection points, allowing for precise mechanical positioning independent of the adhesive bonding. This segmentation enables the holder to maintain angular precision while still achieving reliable electrical connectivity through dedicated contact points.
