Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electromagnetic valve control system uses manual control through physical button, then on-site control is achieved, but remote control capability is lost
Solution Approach 1:
The control system is designed to perform multiple functions: it can operate in remote control mode through 4G/5G network, local control mode through touch screen, and manual control mode through physical buttons. The main control module integrates multiple communication modules (4G/5G, Wi-Fi) and control interfaces to provide universal control capabilities across different scenarios.
Solution Approach 2:
The control system dynamically switches between different control modes based on operational needs. The microcontroller can transition between receiving remote commands via 4G/5G module, local touch screen inputs, and manual physical button signals, adapting the control interface to the current operational context.
2Ease of operation
If electromagnetic valve control system relies on remote control, then remote operation is achieved, but on-site control capability is lost
Solution Approach 1:
The system prepares backup control pathways in advance by integrating both remote control (4G/5G) and local control (touch screen) capabilities. If remote control fails or network is unavailable, the system can immediately switch to local control through the touch screen interface, ensuring continuous operational availability without single-point failure.
Solution Approach 2:
Different control interfaces are provided for different operational contexts: remote control through 4G/5G for distant operation, touch screen for local digital control, and physical buttons for immediate on-site control. Each control mode is optimized for its specific use case, ensuring reliable operation regardless of location or network conditions.
3Ease of manufacture
If valve core mechanism uses thread connection, then assembly is achieved, but disassembly and maintenance difficulty increases
Solution Approach 1:
The valve body is divided into separable sections with the valve core mechanism as an independent module. The valve core mechanism can be detached from the valve body as a complete unit for maintenance, allowing easy replacement and repair without disassembling the entire valve assembly. This modular segmentation maintains simple threaded connections for assembly while enabling easy disassembly for maintenance.
4Adaptability or versatility
If electromagnetic valve is used in low-temperature regions, then operation in cold environments is achieved, but valve freezing and malfunction risk increases
Solution Approach 1:
The heating module converts electrical energy to thermal energy to counteract the harmful low-temperature environment. By integrating heating elements within the valve body, the system actively generates heat to prevent freezing of the valve core mechanism and internal components, transforming the challenge of cold environments into a manageable condition through active thermal compensation.
