Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual testing methods are used for residual seal force and compression friction testing, then the testing process is simple to operate, but the testing speed is slow and labor intensity is high
Solution Approach 1:
The testing system is divided into separate functional modules: a load frame for applying compressive force, a load cell for measuring force, a rotating platen assembly for positioning and testing, and a controller for automation. This segmentation allows each component to be optimized independently while working together to achieve automated high-speed testing.
Solution Approach 2:
The manual mechanical testing process is replaced with an automated system where the load frame mechanically applies controlled compressive forces, the load cell electronically measures the residual seal force, and the controller automates the testing sequence. This substitution of manual operation with automated mechanical and electronic systems increases testing speed and reduces labor intensity.
2Measurement precision
If automated testing systems are implemented, then testing speed and accuracy improve, but the device complexity increases
Solution Approach 1:
The load cell provides real-time feedback on the compressive force applied during testing, allowing the controller to monitor and verify measurement accuracy. The system uses this feedback to ensure precise measurement of residual seal force while maintaining control over the testing process, thereby improving measurement precision without requiring excessive system complexity.
Solution Approach 2:
The rotating platen assembly serves multiple functions: it positions the specimen, applies the compressive load, and facilitates the testing motion. The load frame simultaneously provides structural support and delivers the testing force. By designing components to perform multiple functions, the system achieves high measurement precision while minimizing the increase in overall device complexity.
