Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect the pump support base, support part, and plate, then the components can be firmly joined, but processing accuracy deviations cause gaps and gas leaks
Solution Approach 1:
The patent introduces an angle-adjustable mechanism that allows the support part to dynamically adapt its angle relative to the pump support base and plate. This dynamic adjustment capability enables the system to compensate for manufacturing precision deviations, ensuring tight connections and preventing gas leaks without requiring extremely high welding accuracy.
Solution Approach 2:
The patent changes the fixed geometric parameter (angle) of the connection between components into a variable parameter through the angle-adjustable mechanism. By allowing the angle to be adjusted, the system can accommodate variations in manufacturing precision while maintaining effective sealing and connection, thus resolving the contradiction between connection strength and manufacturing precision requirements.
2Ease of manufacture
If welding deviations occur, then the components can still be assembled, but gas leaks require disassembly and readjustment, reducing assembly efficiency
Solution Approach 1:
The angle-adjustable mechanism provides real-time adaptability during assembly, allowing workers to adjust the support part angle to compensate for welding deviations. This eliminates the need for disassembly and readjustment, thereby maintaining high assembly efficiency while preserving manufacturing flexibility.
Solution Approach 2:
The angle-adjustable mechanism enables the assembly system to self-correct for manufacturing deviations without requiring external intervention or disassembly. The mechanism automatically compensates for gaps and misalignments through angle adjustment, ensuring proper sealing and connection while maintaining assembly efficiency.
3Device complexity
If fixed-angle connections are used, then the structure is simple, but manufacturing deviations cause gaps and gas leaks
Solution Approach 1:
The patent introduces a relatively simple angle-adjustable mechanism that adds minimal structural complexity while dramatically improving sealing reliability. The mechanism allows the support part to dynamically adjust its angle, ensuring tight connections and preventing gas leaks without requiring complex multi-component assemblies.
Solution Approach 2:
By changing the fixed angle parameter to an adjustable one, the patent achieves improved sealing reliability with minimal increase in device complexity. The angle-adjustable mechanism provides the necessary adaptability to compensate for manufacturing deviations while maintaining a relatively simple overall structure.
