Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pressure regulation mechanisms are used, then basic pressure control is achieved, but precision of pressure regulation is insufficient
Solution Approach 1:
The patent implements a dynamic regulation mechanism where the actuation unit can move along the main axis to dynamically adjust the compression force applied to the spring. This dynamic adjustment capability allows precise control of the membrane's position and the pressure regulation output, transforming a static system into a dynamically adjustable one that achieves high precision without excessive complexity.
Solution Approach 2:
The invention changes the physical parameters of the regulation system by introducing a movable actuation unit that can vary the compression force on the spring along the main axis. This parameter change enables continuous adjustment of the pressure regulation characteristic, allowing precise control through quantitative modification of the mechanical parameters rather than relying on complex mechanical linkages.
2Measurement precision
If complex regulation mechanisms are implemented to improve precision, then pressure regulation precision improves, but ease of actuation deteriorates
Solution Approach 1:
The patent merges the opening/closing function and the pressure regulation function into a single integrated actuation unit. By combining these two functions that were previously separated into different mechanisms, the invention allows the user to control both flow control and pressure regulation through one unified interface, significantly improving ease of operation while maintaining precision through the dynamic adjustment capability along the main axis.
Solution Approach 2:
The actuation unit is designed with multi-functionality, serving both as an opening/closing mechanism and as a pressure regulation mechanism. This universal component can perform multiple functions (flow control and pressure adjustment) through its movement along the main axis, eliminating the need for separate controls and simplifying the user interface while achieving precise dual-function control.
3Adaptability or versatility
If separate mechanisms for opening/closing and pressure regulation are used, then functional separation is achieved, but device complexity increases
Solution Approach 1:
The invention merges the opening/closing mechanism and pressure regulation mechanism into a single integrated actuation unit that performs both functions. By combining these functions in one component that moves along the main axis, the patent reduces the overall number of separate mechanisms and control elements, thereby reducing device complexity while maintaining the ability to perform both functions with precision.
