Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional valve means (ball valves) and separate air refilling systems are used, then fluid control function is achieved, but device complexity increases
Solution Approach 1:
The movable element of the actuator element serves dual functions: it acts as both the fluid control valve (first or second valve means) and as part of the air refilling system. This merging of functions eliminates the need for separate valve components and air refilling mechanisms, thereby reducing device complexity while maintaining reliable fluid control and air refilling capabilities.
Solution Approach 2:
The actuator element's movable element is designed to perform multiple functions within a single component structure. It controls fluid passage (acting as valve means) and simultaneously enables air refilling into the container, reducing the number of parts needed and simplifying the overall device construction while ensuring reliable operation of both functions.
2Reliability
If traditional separate valve and air refilling system components are used, then fluid control is achieved, but production costs increase
Solution Approach 1:
By combining the valve function and air refilling function into the actuator element's movable element, the number of separate components is reduced. This leads to lower production costs due to fewer parts to manufacture, assemble, and quality-check, while the integrated design maintains the reliability of both fluid control and air refilling operations.
3Reliability
If traditional air refilling systems are used, then container refilling is attempted, but venting reliability decreases causing container collapse
Solution Approach 1:
The air refilling function is integrated into the actuator element's movable element rather than being a separate system. This simplification improves reliability by reducing the number of potential failure points in the air refilling pathway, ensuring complete and reliable container refilling without the complexity of traditional separate air refilling systems.
4Reliability
If more components are used for valve and air refilling functions, then fluid control precision is improved, but device weight increases
Solution Approach 1:
The movable element of the actuator element is designed to perform both fluid valve control and air refilling functions in a single integrated component. This eliminates the weight of separate valve bodies, springs, and air refilling mechanisms, significantly reducing device weight while maintaining reliable fluid control through the multi-functional design.
