Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable-end connector is used to connect the electrical connector to the conductive cable, then reliable electrical connection is achieved, but internal space is occupied and assembly complexity increases
Solution Approach 1:
The patent extracts and eliminates the cable-end connector from the traditional two-component connection system. The electrical connector is designed to directly engage with the conductive cable without requiring a separate cable-end connector, thereby removing unnecessary components and reducing internal space occupation while maintaining reliable electrical connection.
Solution Approach 2:
The patent merges the functions of the electrical connector and cable-end connector into a single integrated electrical connector design. The electrical connector body incorporates both the electrical connection functionality and the cable engagement capability, allowing direct connection to the conductive cable and eliminating the need for a separate cable-end connector.

3Volume of stationary object
If the electrical connector is miniaturized to save space, then internal space is reduced, but assembly stability may be compromised
Solution Approach 1:
The patent employs a nested structure where the terminal inserting structure is received within the electrical connector body, and the locking structure is integrated within the terminal core and connector body. This nested arrangement allows compact miniaturization while maintaining stable assembly through the interlocking locking structures that prevent disengagement.
Solution Approach 2:
The patent incorporates curved surfaces and rounded features in the locking structures, such as the arc-shaped locking protrusions and corresponding recesses. These curved geometries provide smooth engagement and disengagement while maintaining compact dimensions, ensuring assembly stability without increasing overall size.
