Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If clamping bodies are arranged with longitudinal axes intersecting at multiple points, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The clamping device is divided into multiple clamping bodies, each with its own longitudinal axis. By segmenting the clamping function across multiple bodies with different axis orientations, the system achieves higher positioning precision through the intersection of multiple axes while managing complexity through modular design.
Solution Approach 2:
The longitudinal axes of the clamping bodies are oriented in different spatial dimensions, intersecting at multiple points in three-dimensional space. This dimensional approach allows the system to achieve precise positioning through geometric intersection without requiring overly complex mechanical linkages.
2Force
If fluidic force transmission units are used to actuate clamping bodies, then clamping force is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent replaces complex fluidic force transmission systems with a simpler mechanical actuation system. The operating device directly transmits mechanical force to the clamping bodies through a straightforward mechanical linkage, eliminating the need for hydraulic or pneumatic components while maintaining sufficient clamping force.
Solution Approach 2:
The fluidic force transmission units are extracted and removed from the system. The patent achieves the required clamping force through direct mechanical action, taking out the unnecessary fluidic transmission components that added complexity without providing proportional benefit.
3Adaptability or versatility
If clamping bodies are supported to be movable relative to each other, then adaptability is improved, but friction and operational complexity increase
Solution Approach 1:
The clamping bodies are merged into a coordinated system where they move together in a synchronized manner rather than independently. This combining approach reduces the complexity of individual movement mechanisms while maintaining adaptability through the collective action of multiple clamping bodies.
