Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical interfaces and multiple fastening components are used to secure optical connectors, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts and eliminates unnecessary fastening components (screws, clips, etc.) from the traditional mechanical interface. By removing these separate fastening elements, the design achieves connection reliability through the elastic holding arm's inherent elastic deformation and positioning capabilities alone, thereby reducing assembly complexity and manufacturing cost while maintaining secure connector fixation.
Solution Approach 2:
The patent merges the functions of positioning, fastening, and securing into a single integrated elastic holding arm structure. This unified component combines the positioning frame's structural support with the elastic arm's flexible holding capability, eliminating the need for separate fastening components and simplifying the overall assembly while ensuring reliable connector retention.
2Manufacturing precision
If precise alignment structures are added to ensure accurate optical coupling, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent employs the elastic deformation capability of the holding arm to dynamically adjust and compensate for alignment variations. Rather than relying on rigid, complex precision alignment structures, the elastic arm's flexibility allows it to自适应 (self-adjust) to tolerance variations in connector positioning, achieving accurate optical coupling through elastic deformation while maintaining a simple overall structure.
Solution Approach 2:
The patent changes the physical state of the holding arm from rigid to elastic, utilizing elastic deformation to accommodate alignment variations. This parameter change enables the structure to absorb positioning tolerances through controlled deformation, achieving precise optical coupling without requiring complex rigid alignment mechanisms, thereby reducing structural complexity.
3Stability of the object's composition
If multiple fastening components are used to secure the optical connector, then connection stability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The elastic holding arm performs the fastening function through its own elastic deformation and inherent mechanical properties. The arm's elasticity allows it to automatically adapt to the connector's position and provide stable fixation without requiring external fastening components or complex assembly procedures, thereby simplifying manufacturing while ensuring stable connector fixation.
