Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a terminal block is designed with a simple coupling structure, then the device complexity is reduced and ease of manufacture is improved, but the connection stability deteriorates under vibration leading to loose connections and disengagement
Solution Approach 1:
The patent applies the dynamics principle by designing a pressing mechanism that can dynamically adjust its pressing force on the attachment connector. The pressing mechanism includes a pressing portion that can be actuated to apply dynamic pressing force, transforming the static coupling structure into a dynamic one that can adapt to vibration conditions, thereby maintaining connection stability without excessive complexity
Solution Approach 2:
The patent implements parameter changes by modifying the physical state of the pressing mechanism components. The pressing mechanism includes elastic elements that can deform under actuation, changing the pressing force parameter dynamically. This allows the structure to maintain reliable connection under vibration while keeping the overall design relatively simple
2Reliability
If a terminal block is designed with a secure coupling structure to prevent disengagement, then the connection stability is improved, but the ease of operation for engagement and disengagement deteriorates
Solution Approach 1:
The pressing mechanism provides dynamic control over the coupling strength. During normal operation, the mechanism maintains strong pressing force for stable connection. During disengagement, actuation of the pressing portion releases the pressing force, allowing easy separation. This dynamic adjustment resolves the contradiction between secure coupling and ease of operation
Solution Approach 2:
The pressing mechanism is pre-configured in a engaged state where the pressing portion applies pressing force to secure the attachment connector. This preliminary action ensures connection stability is established before operation begins, while the ability to release this action provides ease of disengagement when needed
3Volume of moving object
If the terminal block uses a compact structure with integrated components, then the volume is reduced and device size is minimized, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the terminal block into distinct modules: the insulative housing with conductive members, the separate attachment connector, and the integrated pressing mechanism. This modular segmentation allows each component to be manufactured independently with standard processes, then assembled together, maintaining ease of manufacture while achieving a compact integrated final product

AI summary
A terminal block structure (1, 1A) is provided and includes an insulative housing (10), separation members (20, 20A) and conductive wire and terminal crimping members (30). The separation member (20, 20A) is secured to the insulative housing and includes a base (21) and a pressing mechanism (22) operably connected to the base (21). The pressing mechanism (22) includes a pressing portion (221) and a tail portion (222) extended outward from the pressing portion (221). The conductive wire and terminal crimping members (30) are arranged inside the insulative housing (10). When an acting force is exerted on the pressing portion (221), the pressing mechanism (22) generates deformation or rotation to drive the tail portion (222) to ascend. Accordingly, the pressing operation of the terminal block structure (1, 1A) is facilitated, and it is equipped with simple structure for easy installation.
