Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional terminal block is used to connect wires, then electrical connection can be established, but it cannot provide plug connection and positioning leg functions simultaneously, requiring additional components
Solution Approach 1:
The patent combines the terminal block body, socket, and positioning legs into a single integrated component. The terminal block body includes integrated positioning legs extending from its sides and a socket formed within its structure, eliminating the need for separate components and reducing assembly steps while providing electrical connection, plug connection, and circuit board mounting functions simultaneously
Solution Approach 2:
The terminal block is designed as a multi-functional component that simultaneously provides wire electrical connection through its conductive contacts, plug connection through the integrated socket, and circuit board mounting through the positioning legs. This universal design allows a single component to replace multiple separate components, improving versatility while reducing overall device complexity
2Adaptability or versatility
If independent sockets are secured to terminal blocks by screw-fastening or welding, then plug connection is enabled, but stability and reliability of the connection deteriorate
Solution Approach 1:
The socket is integrated as an inherent part of the terminal block body rather than being a separate component. The socket is formed within the terminal block structure with its contact elements directly connected to the terminal block's conductive paths, ensuring stable and reliable electrical connection while enabling plug connection capability
3Productivity
If a single terminal block is used, then simple structure is maintained, but it cannot satisfy market demand for connecting multiple wires efficiently
Solution Approach 1:
The terminal block is designed with multiple independent wire connection positions, each with its own conductive contact and clamping mechanism. The terminal block body is segmented into multiple sections that can independently accommodate and connect different wires, allowing efficient connection of multiple wires while maintaining a unified integrated structure

AI summary
A double-wire terminal block structure includes an insulation housing, a conductive terminal block, and a clamp terminal block. The insulation housing includes a press hole and a press block movable with respect to the press hole. The conductive terminal block has a base and two extension arms bent and extending from the base. The clamp terminal block includes a base plate positioned on the base, two flexible arms bent from the base plate, and a contact portion connected to each flexible arm. The press block passes through between the two flexible arms to press each contact portion, so that the two flexible arms are resiliently released from contact with the two extension arms to allow wires to be inserted and clamped between the flexible arms and the extension arms. Accordingly, connecting wire can be achieved easily, conveniently, and efficiently.
