Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If microporous material is used as an auxiliary component in the valve core, then pilot opening characteristics are added to the sealing ring, but the material cannot directly control flow rate and pressure
Solution Approach 1:
The patent merges the microporous material directly into the valve core structure, combining the sealing function and flow control function into a single integrated component. The microporous material forms both the sealing ring and the flow control element, eliminating the need for separate pilot valve structures and auxiliary components.
Solution Approach 2:
The microporous material in the valve core performs multiple functions simultaneously: it provides sealing characteristics, controls flow rate through its porous structure, and enables pressure regulation. This multi-functional design replaces traditional single-function components.
2Device complexity
If flow control is achieved through opening degree of valve core, then结构简单 (simple structure), but precision of flow rate and pressure control is limited
Solution Approach 1:
The patent utilizes the inherent properties of microporous materials to achieve precise flow control. The porous structure allows for fine-tuned flow regulation through compression deformation, where the degree of compression directly controls the effective pore area and thus the flow rate with high precision.
Solution Approach 2:
The patent changes the physical state and parameters of the microporous material through compression deformation. By varying the compression degree, the effective pore size and flow characteristics are dynamically adjusted, enabling precise control of flow rate and pressure without complex mechanical adjustments.
3Measurement precision
If microporous material is compressed to control flow, then flow rate precision is improved, but structural complexity of valve core increases
Solution Approach 1:
The patent combines the microporous material, sealing ring, and flow control element into a single integrated valve core structure. This merging eliminates the need for multiple separate components and complex assembly, while maintaining the precision flow control functionality through the compressed microporous material.
