Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex control device with multiple regulators and valves is used to adjust spray amount and particle size, then measurement precision and manufacturing precision are improved, but device complexity increases
Solution Approach 1:
The patent combines the functions of multiple separate control components (gas regulator, liquid regulator, needle valves) into a single integrated control unit that manages both compressed gas and liquid pressures simultaneously. This merging reduces the number of discrete components while maintaining precise control over spray parameters, directly resolving the contradiction between precision and complexity.
Solution Approach 2:
The control unit is designed with multi-functionality, serving as both a gas regulator and liquid regulator, and incorporating needle valve functions for precise flow control. This universal component performs multiple control functions that previously required separate devices, reducing overall system complexity while preserving adjustment precision for both spray amount and particle size.
2Manufacturing precision
If multiple separate control components are used for gas and liquid pressure regulation, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
By integrating gas pressure regulation and liquid pressure regulation into a single control unit, the patent reduces the number of separate control operations the user must perform. The unified interface allows simultaneous adjustment of both gas and liquid pressures, simplifying the operational workflow while maintaining the precision previously achieved through separate components.
Solution Approach 2:
The control unit incorporates automatic pressure maintenance functions where the system self-regulates gas and liquid pressures based on predetermined setpoints. This self-service capability reduces the need for manual intervention and complex operational procedures, improving ease of operation while preserving manufacturing precision through automated control mechanisms.
