Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the female connector uses a simple cylindrical structure without guiding structures, then the device complexity is reduced, but the reliability deteriorates due to incorrect insertion direction causing voltage mismatches and malfunctions
Solution Approach 1:
The patent applies asymmetry by designing T-shaped cross-section guiding structures with different orientations in the female connector. The first and second guiding structures have T-shaped cross-sections that are asymmetric relative to each other, creating a unique geometric signature that only matches the male connector when inserted in the correct direction. This asymmetric design ensures reliable directional insertion while maintaining relatively simple overall connector structure.
Solution Approach 2:
The patent transitions from a simple cylindrical (1D radial) structure to a multi-dimensional structure by incorporating T-shaped cross-sections with longitudinal and lateral walls. This adds geometric complexity in the transverse dimension while maintaining simplicity in the longitudinal insertion direction, effectively preventing incorrect insertion through cross-sectional shape matching rather than complex multi-directional constraints.
2Reliability
If the female connector incorporates T-shaped cross-section guiding structures with perpendicular intersections, then the reliability of correct insertion is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent implements preliminary action by pre-forming the T-shaped cross-section guiding structures with perpendicular intersections during the connector manufacturing process. These structures are prepared in advance with precise geometric relationships (perpendicular walls, defined T-junctions) that automatically guide the male connector into the correct insertion orientation, eliminating the need for post-assembly adjustments or complex real-time alignment mechanisms.
3Reliability
If the female connector uses multiple partitioned inserting subspaces, then the reliability of terminal matching is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the internal inserting space into multiple distinct subspaces (first, second, third, and fourth inserting subspaces) using the T-shaped cross-section guiding structures. Each subspace corresponds to specific terminal connections, ensuring that male connector pins are guided to the correct female terminals. This segmentation organizes the connection pathways clearly while maintaining a unified connector body structure.

AI summary
A female connector, wherein the female connector is provided to allow insertion of a male connector in the inserting direction. The insulation core of the female connector comprises an inserting guiding structure, which provides interference when the male connector is inserted in an incorrect inserting direction to prevent incorrect insertion of the male connector into the female connector, thereby enabling the male connector to be inserted into the female connector for power or signal transmission.
