Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the jumper is loosely positioned on the micro optical engine, then assembly is easier, but optical power coupling is unstable and power loss increases
Solution Approach 1:
The fixation system is segmented into multiple functional components: alignment members for horizontal positioning, spring arms for vertical positioning, and a latch mechanism for securing. This segmentation allows each component to address specific positioning requirements independently, achieving stable optical coupling while maintaining assembly simplicity.
Solution Approach 2:
Alignment members are pre-installed on the micro optical engine to establish precise horizontal alignment before the jumper is positioned. This preliminary alignment action ensures that when the jumper is placed, optical coupling is already optimized, reducing assembly complexity while guaranteeing coupling stability.
2Reliability
If the jumper is tightly fixed to the micro optical engine, then optical power coupling stability is improved, but assembly complexity increases
Solution Approach 1:
The spring arms utilize the jumper's own weight and the natural spring force to achieve positioning and fixation. The latch mechanism automatically secures the assembly when engaged, eliminating the need for additional fastening operations or complex adjustment mechanisms, thus maintaining simplicity while ensuring stable optical coupling.
3Manufacturing precision
If alignment members are added to limit horizontal movement, then optical coupling precision is improved, but device complexity increases
Solution Approach 1:
The alignment members are integrated directly onto the micro optical engine structure, merging the alignment function with the existing component rather than adding separate external fixtures. This integration achieves precise horizontal alignment while minimizing additional structural complexity.
4Strength
If spring arms are used to limit vertical movement, then mechanical integrity is improved, but device complexity increases
Solution Approach 1:
The spring arms function as flexible elastic elements that provide vertical positioning and mechanical support. This flexible approach achieves strong mechanical integrity and shock absorption while using simple thin-walled structures, avoiding the need for rigid complex support frameworks.
