Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-center-distance FPC connector is used, then the connection is reliable for wires with matching center distance, but the connector cannot be universally applied to wires with different center distances
Solution Approach 1:
The patent applies the dynamics principle by making the connector adaptable through adjustable positioning structures. The positioning pins can be adjusted to different positions to match different wire center distances, transforming a static fixed-distance connector into a dynamic adaptable one. This allows a single connector design to accommodate multiple wire configurations without requiring multiple fixed-specification connectors.
Solution Approach 2:
The patent implements universality by designing a connector that can serve multiple functions - connecting wires with different center distances using the same connector body. The adjustable positioning mechanism enables one connector design to replace multiple fixed-specification connectors, achieving multi-functionality and reducing the variety of connector specifications needed.
2Reliability
If different specifications of FPC connectors are used for different wire configurations, then each wire type can be connected reliably, but it requires maintaining multiple connector inventories and increases complexity
Solution Approach 1:
The connector maintains reliable electrical connection while incorporating adjustable positioning pins that can be dynamically positioned to match different wire center distances. This dynamic adjustment capability allows a single connector design to adapt to various wire configurations, eliminating the need for multiple fixed-specification connectors while preserving connection reliability.
Solution Approach 2:
The patent creates a universal connector design that can reliably connect different wire types by adjusting the positioning pins. This multi-functional connector replaces the need for maintaining multiple connector specifications, achieving both reliability and reduced inventory complexity.
3Adaptability or versatility
If a barbed metal strip with spikes is used for piercing connection, then the electrical contact is reliable and adjustable for different center distances, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the connector into modular components - the barbed metal strip with spikes is separated from the positioning mechanism. This allows the piercing function and the positioning function to be independently manufactured and then assembled, reducing overall manufacturing complexity while maintaining adjustability for different wire configurations.
Solution Approach 2:
The barbed metal strip with spikes is designed to automatically pierce and secure the wire insulation during assembly, eliminating the need for separate fastening operations. The spikes self-engage with the wire, providing both electrical contact and mechanical retention in a single integrated feature, thereby simplifying the manufacturing process.

AI summary
A sensing apparatus, a piercing terminal, a stamping strip and a corresponding method are provided. Flat copper wires at tail ends of parallel wires of a FPC film are pierced, pressed tightly and fixed by first to fourth spikes on a metal strip. The first to fourth spikes are electrically connected to the flat copper wires at positions where the flat copper wires are pierced respectively, achieving an electrical connection between two piercing terminals and the two flat copper wires at the tail ends of the parallel wires of the FPC film, helping ensure the reliability of the electrical connection. Further, the piercing terminals are suitable for parallel wires of FPC films with different specifications.
