Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional gas path changeover switch is used to control gas charging or discharging, then gas path control is achieved, but the gas supply device cannot be simultaneously controlled and additional components are required
Solution Approach 1:
The patent combines the gas path changeover switch and gas supply control device into a single integrated valve body. The first valve rod controls both the gas path switching (through first and second valve seats) and the gas supply control (through third valve seat), eliminating the need for separate control devices and reducing overall system complexity while maintaining full control functionality.
Solution Approach 2:
The integrated valve body performs multiple functions: it acts as a gas path changeover switch (controlling charging and discharging paths) and simultaneously functions as a gas supply control device (controlling gas outlet). The first valve rod and its associated components handle both gas path switching and gas supply regulation, making the device universal and reducing the number of required components.
2Adaptability or versatility
If separate gas path changeover switch and gas supply control device are installed, then full control functionality is achieved, but installation space increases and piping arrangement becomes complicated
Solution Approach 1:
By merging the gas path changeover switch and gas supply control device into a single integrated valve body with multiple valve seats and a unified control mechanism, the patent significantly reduces the installation space required. The consolidated structure eliminates the need for separate device housings and reduces piping complexity, as all control functions are accessed through a single operational interface.
3Ease of operation
If a gas path changeover switch with hollow valve rod is used, then gas path switching is achieved, but simultaneous control of gas supply device is not possible
Solution Approach 1:
The patent merges the gas path switching function and gas supply control function into a single valve body structure. The first valve rod extends through the valve body and can simultaneously actuate multiple valve seats (first, second, and third), enabling both gas path switching and gas supply control to be achieved through a single operational mechanism.
Solution Approach 2:
The integrated valve body design provides multi-functionality by incorporating multiple valve seats and channels within a single structure. The first valve rod and its control mechanism can simultaneously manage gas path switching (charging/discharging) and gas supply control, making the device versatile and capable of simultaneous multi-function operation.
