Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flexible plastic tubes are used to direct heating/cooling fluids towards the test piece, then the test system can be simple and easy to install, but the test scenario deteriorates over time with respect to initially set parameters
Solution Approach 1:
The system transitions from static flexible tubes to a dynamic positioning system with adjustable fluid providing means that can be precisely positioned and fixed at different locations around the test piece, allowing the test scenario to be maintained stably over time while remaining easy to install and reconfigure
Solution Approach 2:
The system incorporates feedback mechanisms through position means with markings and gratings that allow monitoring and adjustment of the fluid providing means position, ensuring the test scenario parameters remain stable and reproducible over time
2Ease of operation
If the fluid providing means are freely positioned, then the system is flexible and easy to operate, but the relative position cannot be reproducibly fixed
Solution Approach 1:
The positioning system is segmented into discrete position means with specific markings and gratings that can be independently adjusted and fixed, allowing flexible operation while enabling precise reproduction of relative positions through standardized positioning elements
Solution Approach 2:
The system performs preliminary positioning actions by establishing predefined position references through markings and gratings before the actual testing, ensuring that the fluid providing means can be reproducibly fixed at desired locations while maintaining operational flexibility
