Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual placement and adjustment of connector is used, then operation flexibility is maintained, but detection efficiency and alignment precision deteriorate due to multiple adjustment attempts
Solution Approach 1:
The connector fixture enables automatic clamping and positioning of the connector through self-aligning mechanisms. The V-shaped clamping groove and elastic clamping structure allow the connector to automatically locate itself in the correct position without manual intervention, thereby improving both detection efficiency and alignment precision
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated fixture system that uses elastic deformation, friction, and geometric constraints to achieve precise positioning. The elastic clamping structure automatically adjusts to the connector's position, eliminating the need for repeated manual alignment attempts
2Ease of operation
If manual adjustment of connector angle is performed, then adaptability to different positions is maintained, but time consumption increases due to repeated adjustment attempts
Solution Approach 1:
The fixture is pre-configured with a V-shaped clamping groove and elastic clamping structure that are designed to automatically guide and position the connector in the correct orientation upon insertion. This preliminary setup eliminates the need for subsequent manual adjustment operations
Solution Approach 2:
The elastic clamping structure automatically adjusts to the connector's dimensions and position, providing self-aligning functionality that simplifies the operation to a single insertion action without requiring operator intervention for angle adjustment
3Measurement precision
If fixed clamping structure is used, then structural simplicity is maintained, but positioning precision deteriorates due to inability to accommodate minor position variations
Solution Approach 1:
The patent employs an elastic clamping structure that can dynamically adjust its clamping force and position within the V-shaped groove. This dynamic capability allows the fixture to accommodate minor position variations while maintaining precise positioning, without requiring a complex adjustable mechanism
Solution Approach 2:
The elastic material of the clamping structure changes its physical parameters (deformation, stiffness) in response to the connector's position, allowing automatic compensation for position variations while maintaining precise alignment. This passive parameter adjustment avoids the need for active control mechanisms

Function Achieved in This Case
Enhances detection efficiency and quality by automating the alignment process, reducing manual adjustments and improving the accuracy of insertion depth measurements.
Implementation Method 1
A first inclined plane is formed on one end of the clamping claw, and a second inclined plane is formed on the inner side of the groove and is mated with the first inclined plane to convert an axial movement of the transmission component into a radial movement of multiple clamping claws
Implementation Method 2
an elastic element which is compressed between the clamping claw and the installation block to radially push the clamping claw towards the second inclined plane
