Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If non-contact connector with embedded coils is used for wireless power transmission, then power transmission capability is improved, but assemblability deteriorates due to complex alignment requirements
Solution Approach 1:
The connector main bodies are designed with nested structures where the second connector main body fits into the first, and housing parts are nested within each other. This nesting design simplifies assembly by reducing the number of separate components and alignment steps required, directly addressing the assemblability issue while maintaining the wireless power transmission capability through embedded coils.
Solution Approach 2:
The connector employs asymmetric design elements such as the fitting recess and protrusion structure that guide proper alignment during assembly. The asymmetric housing configuration ensures correct orientation of the embedded coils without requiring complex alignment procedures, thus improving assemblability while preserving power transmission functionality.
2Adaptability or versatility
If multiple coils for power and signal transmission are integrated, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines power transmission coils and signal transmission coils within the same connector main bodies, integrating multiple functions into a single device. The housing structures and fitting mechanisms are merged to accommodate both coil types, reducing overall system complexity while maintaining full functionality for both power and signal transmission.
Solution Approach 2:
The connector main bodies are designed as universal components that can simultaneously handle power transmission and signal transmission functions. The embedded coils are configured to perform multiple functions within a single connector assembly, reducing the need for separate dedicated connectors and thereby simplifying the overall device complexity.
3Stability of the object's composition
If elastic contact between housings is implemented, then connection stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The housing design includes pre-formed elastic contact surfaces and fitting recesses that are manufactured with standard tolerances. The elastic contact is built into the housing structure itself, eliminating the need for high-precision post-assembly adjustments. This preliminary design approach ensures connection stability without imposing excessive manufacturing precision requirements.
