Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is added to automatically lock the lid to the preparation vessel, then user safety is improved, but device complexity increases
Solution Approach 1:
The locking device combines multiple functions into a single integrated mechanism that simultaneously locks the lid to the preparation vessel and transmits movement to actuate the valve. The housing structure itself serves as part of the locking mechanism, merging the locking function with the structural support function, thereby improving safety without proportionally increasing complexity.
Solution Approach 2:
The locking device is designed to perform multiple functions: securing the lid to the preparation vessel, transmitting mechanical movement to the valve actuating device, and providing structural support. This multi-functionality reduces the need for separate components, thereby improving user safety while minimizing the increase in device complexity.
2Ease of operation
If spring force is used to actuate valve movement, then ease of operation is improved, but control precision deteriorates
Solution Approach 1:
The valve actuating device serves as an intermediary between the spring force and the valve. It translates the simple opening movement generated by spring force into precise control of the valve's opening and closing. This intermediary mechanism maintains ease of operation while achieving the required control precision for valve actuation.
Solution Approach 2:
The system replaces complex mechanical control systems with a simpler spring-based mechanism for valve actuation. The spring provides the necessary force with minimal user input, while the valve actuating device ensures precise positioning. This substitution improves ease of operation while maintaining adequate control precision through careful mechanical design.
