Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual assembly is used for thin elastic contact members, then assembly flexibility is maintained, but labor costs increase and assembly quality becomes variable
Solution Approach 1:
The clamping device is segmented into multiple independent clamping units, each with its own clamping爪 (clamping pawl). This segmentation allows the device to handle thin elastic contact members effectively while maintaining a relatively simple overall structure. Each clamping unit can be independently adjusted and controlled, enabling automated assembly without requiring an overly complex monolithic device.
2Force
If clamping force is applied to thin elastic contact members, then assembly is enabled, but deformation or damage may occur
Solution Approach 1:
The clamping device employs local quality by distributing clamping force through multiple clamping units with individually optimized contact surfaces. Each clamping unit is designed with specific surface characteristics that match the local geometry of the elastic contact member, ensuring force is applied at optimal locations. This localized approach prevents concentration of stress that would cause deformation or damage while still achieving effective clamping.
Solution Approach 2:
The device utilizes parameter changes by adjusting the clamping force magnitude and distribution based on the specific characteristics of the elastic contact member. The clamping units can be independently adjusted to apply appropriate force levels, and the system can adapt parameters such as clamping position and force intensity to prevent deformation while maintaining effective assembly operation.
3Manufacturing precision
If uniform clamping force is distributed across the elastic contact member, then deformation is prevented, but device structure becomes more complex
Solution Approach 1:
The clamping device achieves uniform force distribution through segmentation into multiple identical or similar clamping units. Each unit applies force at a specific location, and the collective action of all units distributes the total clamping force uniformly across the elastic contact member. This segmented approach achieves high manufacturing precision without requiring a single complex force-distribution mechanism.

AI summary
A clamping device includes an installation plate and a pair of clamping claws installed on the installation plate. One of the clamping claws has a first clamping surface and the other has a second clamping surface. The first clamping surface contacts a side of a fixed part of the elastic contact member and a row of first elastic arms. The second clamping surface contacts another side of the fixed part and a row of second elastic arms. The first clamping surface matches an outer surface of the side of the fixed part and a plurality of outer surfaces of the row of first elastic arms, the second clamping surface matches an outer surface of the other side of the fixed part and a plurality of outer surfaces of the row of second elastic arms. A clamping force applied by the clamping claws is evenly distributed on the elastic contact member.
