Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If existing emergency degassing valve apparatus designs are used, then pressure relief function is provided, but the device requires significant design space and lacks compactness
Solution Approach 1:
The pressure compensation element is integrated within the pressure cap structure, with the first and second pressure compensation valves nested inside the compact housing. This nesting approach allows the device to maintain full pressure relief functionality while occupying minimal design space, directly resolving the contradiction between compactness and reliability.
Solution Approach 2:
The invention merges the emergency degassing valve function with the pressure compensation element into a single integrated apparatus. The pressure cap simultaneously serves as both the emergency release mechanism and the housing for the pressure compensation valves, eliminating the need for separate components and reducing overall design space while maintaining safety and reliability.
2Volume of moving object
If a compact design is implemented, then design space is reduced, but the device may lack alternative pressure compensation mechanisms
Solution Approach 1:
The pressure compensation element provides multi-functional capability within the compact design. The first pressure compensation valve handles positive pressure compensation while the second pressure compensation valve handles negative pressure compensation, allowing the device to adapt to various pressure conditions without requiring additional external components or increasing design space.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides safe, reliable, and compact pressure relief with minimal design space, capable of compensating for both positive and negative pressures, while protecting against mechanical damage and environmental exposure.
Implementation Method 1
a spring device, which is configured so as to exert a specified force on the pressure cap so that the pressure cap is retained in a closed position, wherein the spring device is configured such that, upon reaching a specified internal pressure in a space to be degassed, the spring device releases the pressure cap
Implementation Method 2
a gas-permeable protective membrane to ensure reliable and safe operation
