Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive is used to fix the optical receptacle, then installation is simple, but reliability deteriorates due to loosening over time
Solution Approach 1:
The fixation system is segmented into multiple independent elastic pieces (first elastic piece, second elastic piece) that work together to secure the optical receptacle. Each elastic piece independently provides positioning and pressing forces, ensuring that if one element fails, the others maintain fixation reliability while keeping installation straightforward.
Solution Approach 2:
The patent transitions from static adhesive fixation to dynamic elastic fixation. The elastic pieces can dynamically adjust to accommodate the optical receptacle during installation and maintain reliable fixation during operation through their elastic deformation capability, preventing loosening while preserving ease of installation.
2Reliability
If laser welding is used to fix the optical receptacle, then fixation reliability is improved, but ease of repair deteriorates as the receptacle must be scrapped
Solution Approach 1:
The patent enables recovery and reuse of the optical receptacle by replacing the permanent laser welding process with reversible elastic fixation. The elastic pieces allow the receptacle to be removed and reinstalled multiple times without damage, eliminating the need to scrap the receptacle after repair while maintaining reliable fixation during normal operation.
3Reliability
If EMI protection member with elastic piece is used to fix the optical connector, then fixation reliability is improved, but device complexity increases due to positioning difficulty
Solution Approach 1:
The patent employs asymmetric design in the elastic pieces where the first elastic piece has a first end and second end with different functional characteristics, and similarly for the second elastic piece. This asymmetric configuration simplifies the positioning process by providing natural orientation cues and reducing the complexity of achieving correct alignment during assembly while maintaining reliable fixation.
Solution Approach 2:
The elastic pieces are pre-configured with specific geometric features and elastic properties before assembly. This preliminary preparation ensures that when the optical receptacle is installed, the elastic pieces automatically assume their correct positioning and applying forces, eliminating the need for complex real-time adjustment during assembly and reducing overall device complexity.
4Ease of repair
If pressing piece is plugged into plugging structure, then ease of repair is improved, but manufacturing precision deteriorates due to positioning difficulty
Solution Approach 1:
The plugging structure and pressing piece are designed with complementary geometric features that create equipotential positioning conditions. The pressing piece fits into the plugging structure with natural alignment features that ensure consistent positioning without requiring high-precision manufacturing, achieving both easy repairability and adequate positioning precision through form-fit design.
