Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal block is coupled with an engaging connector for signal transmission, then the connection enables data and power transfer, but the coupling is easily affected by vibrations causing poor contact, loosening, or release leading to circuit breaking
Solution Approach 1:
The patent employs a dynamic locking mechanism where the locking ball can move between locked and unlocked positions in response to vibration forces. The spring-loaded design allows the locking mechanism to adapt dynamically to vibration conditions, maintaining reliable connection during normal operation while enabling easy release when needed.
Solution Approach 2:
The locking ball and groove structure provides preliminary anti-action against vibration-induced loosening. The locking ball engages with the locking groove in advance to prevent the terminal block from detaching due to vibrations, counteracting the harmful effect before it can cause connection failure.
2Reliability
If a locking mechanism with a locking ball and groove is used to prevent loosening, then connection reliability is improved, but the structure becomes more complex
Solution Approach 1:
The locking ball is integrated directly into the terminal block body, and the locking groove is formed on the engaging connector, merging the locking function into the existing connection structure. This integration avoids adding separate locking components while achieving reliable vibration resistance.
Solution Approach 2:
The spring-loaded locking ball automatically engages with the locking groove when the terminal block is inserted, providing self-service locking without requiring additional operations. The mechanism uses the insertion force itself to compress the spring and engage the locking ball, simplifying the overall structure while maintaining reliability.
3Ease of operation
If a rotary member with arc-shaped plate is used for unbuckling operation, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The arc-shaped plate on the rotary member provides a curved surface that naturally guides the user's pressing motion. This curvature converts linear pressing force into rotational motion, making the unbuckling operation intuitive and easy to perform while using a simple rotary mechanism rather than complex multi-component assemblies.
Solution Approach 2:
The rotary member serves multiple functions: it acts as both the operating interface for unbuckling and as part of the mechanical linkage to the locking ball. This multi-functionality reduces the need for separate components, maintaining simplicity while achieving ease of operation.

Implementation Method 1
the rotary member includes a first arm part, a second arm part extended from the first arm part and a rotary part disposed between the first arm part and the second arm part
Implementation Method 2
when the first arm part is applied with an external force, the rotary member rotates about the rotary part as a rotation center to drive the second arm part to ascend to make the buckling unit and the buckled unit be unbuckled
