Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple manometric interfaces with different structures and positions are produced to meet different load requirements, then the output value of the manometric interface can be qualified, but the production cost increases and quality monitoring becomes more difficult
Solution Approach 1:
The manometric interface is designed to be movable along the axial direction of the first through hole, allowing dynamic adjustment of its position. This enables a single interface structure to adapt to different load requirements by changing its location, eliminating the need for multiple fixed structures and reducing production complexity
Solution Approach 2:
The single manometric interface structure with adjustable position serves multiple functions for different load conditions. By moving the interface to different positions along the axial direction, it can qualify output values for various loads, making one component universal rather than requiring multiple specialized components
2Manufacturing precision
If the position or shape of the manometric interface is changed to achieve qualified output values, then different load requirements are met, but multiple manometric interfaces with different structures must be produced
Solution Approach 1:
Instead of producing multiple static interfaces with different shapes, the invention uses a single interface that can dynamically change its effective position along the axial direction. This maintains manufacturing precision for each position while reducing the number of different structures to one standardized design
Solution Approach 2:
The invention changes the position parameter of the manometric interface along the axial direction to achieve different output values for various loads. This parameter adjustment approach allows one interface structure to replace multiple structures with different parameters
