Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional mounting and adhesive techniques are used, then assembly is simpler, but alignment precision and coaxiality between laser and collimating lens deteriorate
Solution Approach 1:
The mounting structure is segmented into multiple functional components: positioning ribs for precise location, elastic pieces for adjustable clamping force, and transparent rigid rings for structural support. This segmentation allows each component to perform its specific function optimally, achieving high alignment precision without excessive overall complexity.
Solution Approach 2:
Positioning ribs and elastic pieces are pre-installed on the mounting structure before final assembly. This preliminary action ensures that when the laser and collimating lens are mounted, the alignment features are already in place, guiding precise positioning and reducing the complexity of final alignment adjustments.
2Ease of repair
If detachable mounting is used, then maintenance and replacement are easier, but stability and alignment consistency worsen
Solution Approach 1:
The elastic pieces are pre-installed with built-in clamping grooves that engage with positioning ribs on the laser housing. This preliminary setup ensures that when the laser is detached and reinstalled, it automatically returns to the precise aligned position, maintaining reliability while enabling easy replacement.
Solution Approach 2:
The elastic pieces act as intermediaries between the fixed mounting structure and the detachable laser component. They provide both the mechanical connection for easy detachment and the positioning function for alignment stability, resolving the contradiction between ease of repair and alignment reliability.
3Strength
If photosensitive adhesive is used, then bonding strength and precision are improved, but curing process complexity and time increase
Solution Approach 1:
The patent replaces traditional mechanical fastening methods with photosensitive adhesive bonding. The adhesive provides superior bonding strength and precision alignment compared to mechanical fasteners, while the UV curing process can be completed rapidly with appropriate lighting, offsetting the perceived time penalty.
Solution Approach 2:
The bonding process utilizes parameter changes in the photosensitive adhesive - remaining in a tacky state during assembly to allow precise positioning, then rapidly curing when exposed to UV light. This parameter change enables both high bonding strength and efficient processing time.
