Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a point-contact manner is used between the contact structure and the wire core, then the device complexity is reduced, but the electrical connection quality deteriorates
Solution Approach 1:
The patent transitions from point-contact (0D/1D) to surface-contact (2D) by designing the contact structure with a contact surface that spans across the wire core. The elastic sheet body with acute-angular structure creates a planar contact interface instead of a single point, fundamentally changing the dimensionality of the contact interface to improve electrical connection quality.
Solution Approach 2:
The patent changes the contact geometry parameters from point-like to surface-like by introducing the acute-angular structure with specific angular parameters. The contact surface area and contact pressure distribution are optimized through geometric parameter design, transforming the contact mode to achieve better electrical connection.
2Manufacturing precision
If a point-contact manner is used between the contact structure and the wire core, then the manufacturing precision requirements are reduced, but the wire detachment resistance deteriorates
Solution Approach 1:
The patent addresses the weakness of point-contact in wire detachment resistance by expanding the contact to a surface. The acute-angular structure creates a planar interface that distributes mechanical stress, making the connection more resistant to detachment forces while maintaining ease of manufacturing through standardized geometric features.
3Reliability
If an elastic sheet body with acute-angular structure is used to provide surface contact, then the electrical connection quality is improved, but the device complexity increases
Solution Approach 1:
The patent employs an elastic sheet body as a flexible thin film structure to achieve the desired surface contact. This thin film approach provides the necessary compliance and contact surface area while keeping the overall structure relatively simple and manufacturable, balancing electrical connection quality with structural complexity.
Solution Approach 2:
The elastic sheet body introduces dynamic characteristics to the contact structure, allowing it to deform and adapt to the wire core geometry. This dynamic compliance ensures reliable surface contact and electrical connection while the elastic recovery provides maintaining force, achieving high reliability without excessive structural complexity.

AI summary
A wire-clamping connector is provided. The wire-clamping connector includes a housing and a contact element. The housing includes a through hole. The contact element is disposed in the housing, and includes a bottom plate structure and an elastic sheet body. The bottom plate structure is disposed opposite to a top wall of the housing, and includes a protruding portion that has a contact surface. A terminal portion of the elastic sheet body is fixed to the top wall, and the elastic sheet body has an acute-angular structure configured to be adjacent to the contact surface. An insertion interval is defined between the acute-angular structure and the contact surface. A wire core of a wire inserted in the through hole enters the insertion interval and is clamped together by the acute-angular structure and the contact surface, and an elastic restoring force is generated by the pressed elastic sheet body.
