Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-based connection is used to mount the coil portion, then the connection reliability is improved, but the assembly efficiency deteriorates due to time-consuming alignment and tightening operations
Solution Approach 1:
The invention extracts and removes the screw connection elements from the assembly process. The coil portion is directly integrated with the valve body through a simplified structural design, eliminating the need for separate fasteners and connection operations, thus improving assembly efficiency while maintaining connection reliability
Solution Approach 2:
The invention merges the coil portion and valve body into an integrated structure where the coil portion is directly mounted on the valve body without separate fastening elements. This integration eliminates the need for screw alignment and tightening operations while ensuring stable connection during operation
2Strength
If screw-based connection is used to mount the coil portion, then the connection strength is improved, but the device complexity increases due to additional fasteners and assembly steps
Solution Approach 1:
The invention removes all screw fasteners and associated connection elements from the coil portion mounting structure. The simplified design achieves adequate connection strength through direct structural integration, reducing the number of parts and assembly steps
Solution Approach 2:
Instead of using separate fastening elements to achieve connection, the invention inverts the approach by designing the coil portion and valve body to directly interface with each other through complementary geometric features, achieving both strength and simplicity
3Stability of the object's composition
If traditional screw connection is used, then the mounting stability is improved, but the reliability deteriorates under vibration conditions due to screw loosening
Solution Approach 1:
The invention eliminates screw fasteners that are prone to loosening under vibration. The direct integration design ensures that the coil portion remains firmly attached to the valve body through structural continuity, maintaining both mounting stability and operational reliability in vibration-prone environments
Solution Approach 2:
By merging the coil portion mounting structure with the valve body into a unified design, the invention eliminates weak connection points. The integrated structure ensures consistent mechanical coupling that resists vibration-induced loosening while maintaining mounting stability
