Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable connector is directly connected to the cable in a one-piece molding, then the structure is simple, but the wire is likely to be electrically disconnected or torn due to frequent bending
Solution Approach 1:
The connector is divided into separate components: the connector body, the enclosing body, and the shielding shell. This segmentation allows the wire to be securely enclosed and protected from mechanical stress while maintaining structural simplicity. The wire passes through the enclosing body which is pivotally connected to the shielding shell, creating distinct functional zones that protect the electrical connection.
Solution Approach 2:
The enclosing body is designed to enclose and protect the wire before it connects to the connector body. This protective enclosure acts as a cushioning structure that prevents the wire from being torn or disconnected during frequent bending operations. The pivotal connection between the enclosing body and shielding shell allows for movement while maintaining protection.
2Reliability
If the cable connector is designed to be pivotable with round electrodes and flexible pins, then the electrical connection is maintained during deflection, but the structure is complex and positioning is difficult
Solution Approach 1:
The invention extracts the essential protective function from the complex round electrode and flexible pin structure. Instead of using multiple discrete components (round electrodes and flexible pins), the design uses a single enclosing body that pivotally connects to the shielding shell. This extraction simplifies the structure while maintaining the ability to maintain electrical connection during deflection.
Solution Approach 2:
The enclosing body combines multiple functions into a single component: it encloses the wire, provides pivotal movement capability, and maintains electrical connection. This merging of functions reduces the number of parts needed compared to the round electrode and flexible pin design, simplifying the overall structure while achieving the same reliability goals.
3Device complexity
If flexible pins contact round electrodes in a point contact manner, then the structure is simple, but poor contact occurs easily due to elastic fatigue or position deviation
Solution Approach 1:
The invention transitions from point contact (zero-dimensional) to surface contact (two-dimensional). The enclosing body provides a broader contact area with the wire, distributing the contact stress over a larger area rather than concentrating it at a single point. This dimensional change prevents poor contact due to elastic fatigue or position deviation while maintaining structural simplicity.

AI summary
A cable connector includes a shielding shell, a rotating head, and a plurality of wires, wherein the rotating head is pivotally connected to the shielding shell. The rotating head has an enclosing body formed by injection molding. The enclosing body is a solid structure and encloses a circuit board and a connector that are electrically connected to each other. The connector is partially exposed outside the enclosing body. The wires pass through the shielding shell, wherein an end of each wire passes through the enclosing body and is connected to the circuit board. In this way, when the rotating head is pivoted, the wires are not easy to be torn off, which ensures a good electrical connection to enhance the reliability and the stability of the data transmission.
