Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate fiber optic adapter and connector designs are used, then functional requirements are met, but device complexity and assembly steps increase
Solution Approach 1:
The patent combines the fiber optic adapter and connector into a single integrated unit. The adapter housing and connector housing are merged into one structure, eliminating the need for separate adapter and connector assemblies. This integration reduces the total number of parts while maintaining the environmental sealing and robust fastening functions through a unified design that incorporates sealing elements and fastening mechanisms within the single housing structure.
2Ease of manufacture
If multiple separate components are used for adapter and connector, then functional requirements are met, but assembly complexity increases
Solution Approach 1:
The adapter and connector are manufactured as a single integrated component, eliminating multiple assembly steps. The unified housing structure is formed in one manufacturing process, and the ferrule assembly is directly mounted within the integrated housing without requiring separate adapter assembly operations. This single-unit approach simplifies both manufacturing and assembly while reducing the number of parts that need to be handled and secured.
3Reliability
If ruggedized design with environmental sealing is implemented, then reliability is improved, but cost increases
Solution Approach 1:
The environmental sealing features are integrated directly into the unified housing structure rather than being added as separate components. The sealing elements are incorporated during the single manufacturing process of the integrated housing, eliminating the need for additional sealing assemblies. This integration approach maintains the ruggedized design with proper environmental sealing while reducing manufacturing complexity and cost compared to assembling multiple separate sealed components.
