Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex mechanisms and multiple parts are used to regulate gas flow and open the safety valve, then reliable gas flow regulation and safety valve operation can be achieved, but device complexity increases and potential for leaks increases
Solution Approach 1:
The actuator element combines multiple functions into a single component: it acts as both the safety valve opening mechanism and the gas flow regulation actuator. The actuator element rotates to simultaneously open the safety valve and regulate gas flow through the outlet hole, eliminating the need for separate mechanisms and reducing the number of parts while maintaining reliable operation
Solution Approach 2:
The actuator element is designed as a multi-functional component that performs both safety valve actuation and gas flow regulation. By integrating these two functions into one element, the patent reduces device complexity and the number of potential leak points while ensuring both safety and regulatory functions are reliably performed
2Ease of operation
If multiple parts are used to open the safety valve and regulate gas flow, then proper gas flow control can be achieved, but the number of parts increases leading to higher cost and more potential leak points
Solution Approach 1:
The actuator element merges the safety valve opening function and gas flow regulation function into a single component. When the actuator element rotates, it simultaneously performs both actions, reducing the total number of parts while maintaining full operational capability for gas flow control
Solution Approach 2:
The actuator element is designed as a universal component that handles both safety valve actuation and gas flow regulation. This multi-functionality reduces the quantity of parts needed in the system, lowering cost and reducing potential leak points while preserving ease of operation for gas flow control
