Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the conventional electric valve switches immediately from opening state to closing state upon receiving a valve close signal, then the valve response speed is improved, but the ability to control fluid flow amount is lost
Solution Approach 1:
The patent applies dynamics by making the valve switching behavior adjustable rather than fixed. The microprocessor control unit enables the valve to dynamically adapt its response characteristics - it can switch immediately when needed for fast response, or implement a time-delayed switching for controlled flow reduction. This transforms the valve from a static immediate-switching device to a dynamic system that can optimize between response speed and flow control based on operational requirements.
2Device complexity
If the conventional electric valve operates without a backup power source, then the device complexity is reduced, but the reliability during power outages deteriorates
Solution Approach 1:
The patent implements beforehand cushioning by incorporating a backup battery pack that is charged in advance during normal operation. When a power outage occurs, the backup battery pack immediately provides power to maintain valve operation. This pre-prepared energy reserve cushions against the harmful effect of power outages, ensuring continuous reliable operation without requiring complex alternative power systems.
3Ease of manufacture
If the conventional electric valve requires manual operation during power outages, then the ease of manufacture is improved, but the ease of operation during emergencies deteriorates
Solution Approach 1:
The patent applies self-service by enabling the valve to automatically operate during power outages using the backup battery pack. The microprocessor control unit detects the power outage condition and automatically switches to backup power, allowing the valve to service itself without requiring manual intervention. This transforms the valve from a system that needs human operation during emergencies to an autonomous system that maintains functionality independently.
