Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the connector uses a fixed rigid structure, then the manufacturing precision is improved, but the adaptability to design deviations deteriorates
Solution Approach 1:
The patent introduces a flexible connecting member that can dynamically adjust its position and orientation to accommodate design deviations between electrical components. The flexible connecting member includes bending sections that allow the connector to adapt to misalignments while maintaining stable electrical contact, resolving the contradiction between rigid precision and flexible adaptability.
Solution Approach 2:
The connector design allows for parameter changes in the flexible connecting member, such as bending radius and deflection angle, to adapt to different deviation scenarios. By changing the geometric parameters of the flexible section, the connector can accommodate various design deviations while maintaining manufacturing precision in the rigid connection parts.
2Adaptability or versatility
If the connector allows sliding motion in multiple directions, then the adaptability to design deviations is improved, but the connection stability deteriorates
Solution Approach 1:
The connector is segmented into rigid connection parts and a flexible intermediate section. The rigid parts maintain stable connections at the interfaces with electrical components, while the flexible section provides the necessary sliding motion and adaptation capability. This segmentation allows the connector to simultaneously achieve adaptability and connection stability.
Solution Approach 2:
The flexible connecting member acts as an intermediary between the two rigid connection parts. It mediates the contradiction by providing controlled sliding motion to accommodate deviations while transmitting stable connection forces from both ends, thus maintaining overall connection stability despite the flexibility required for adaptability.
3Reliability
If the connector uses multiple conductive terminals and contact sheets, then the signal transmission reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple conductive terminals and contact sheets are merged into an integrated flexible connecting member structure. The flexible connector incorporates multiple conductive elements that maintain electrical contact through the flexible section, combining the functions of multiple separate components into a single integrated element, thus improving reliability without proportionally increasing complexity.

AI summary
The present invention relates to a connector. Aforementioned connector includes a first connecting member, a second connecting member, and a third connecting member. The first connecting member includes a first case, a first insulator, and a first conductive terminal, wherein the first case defines a first receiving chamber therein, the first insulator is received in the first receiving chamber, an external sidewall of the first case is provided with a first step. The second case defines a containing hole, the PCB board is received in the containing hole, a first end and a second end of the second case each defines a latching groove, the latching grooves is in communication with the containing hole. The third connecting member includes a third case, a second insulator, and a second conductive terminal, wherein the third case defines a second receiving chamber therein. In above connector, because the electrical components coupled to opposite ends of the connector can slide along three directions which are perpendicular to each other, such that a problem of a difficulty of a connection between the connector and the electrical components which is caused by a deviation of the design of the structure of the electrical components can be avoided, thereby a tolerance insensitive of the connector is enhanced.
