Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional valve structures are used, then the valve can perform basic water control function, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent combines multiple valve components into an integrated valve body structure. The valve body integrates the spool, sealing surfaces, and flow passages into a single molded component, eliminating the need for separate molds and reducing assembly steps. This merging approach maintains reliable water control while significantly simplifying the overall valve structure and reducing part count.
Solution Approach 2:
The valve body is designed as a multi-functional component that simultaneously serves as the housing, the spool mechanism, and the sealing element. The integrated design allows the valve body to perform multiple functions (structural support, flow control, sealing) that would traditionally require separate components, thereby reducing complexity while maintaining functionality.
2Manufacturing precision
If multiple components are used in the valve, then the valve can achieve precise control, but the manufacturing cost increases and assembly becomes cumbersome
Solution Approach 1:
The patent merges the spool and valve body into a single integrated component molded from polyoxymethylene resin. This integration eliminates the need for precise assembly between separate spool and body parts, reducing assembly complexity while maintaining control precision through the monolithic structure's inherent dimensional stability and sealing capability.
Solution Approach 2:
The patent specifies precise material parameters by using polyoxymethylene resin with defined mechanical and dimensional properties. This material selection ensures precise control characteristics while enabling cost-effective manufacturing through injection molding, balancing manufacturing precision with ease of manufacture.
3Reliability
If a complex mold structure is used for the spool resetting mechanism, then the valve can achieve reliable operation, but the component molding qualified rate decreases
Solution Approach 1:
The spool resetting mechanism is integrated directly into the valve body mold, eliminating the need for separate complex molds. The valve body is molded as a single piece with the spool resetting features built-in, which simplifies the molding process, improves component qualified rates, and ensures reliable operation through the integrated design.
