Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual curling testing is performed, then operational simplicity is maintained, but testing efficiency and reliability are insufficient
Solution Approach 1:
The transmission mechanism automatically drives the movable part to move along the guide rail, and the curling component automatically curls the flexible sheet through the transmission mechanism, eliminating the need for manual operation while achieving repeated curling and uncurling movements for reliability testing
Solution Approach 2:
The patent replaces manual mechanical operation with an automated transmission mechanism consisting of driving wheels, conveyor belts, and link rods that convert external driving force into rotational motion of the curling component, thereby improving testing efficiency and reliability
2Reliability
If repeated curling and uncurling movements are performed, then curling life and reliability are tested, but device stability may deteriorate
Solution Approach 1:
The patent employs a dynamic transmission mechanism where the movable part moves along the guide rail and the curling component rotates dynamically to perform repeated curling and uncurling movements, allowing the device to maintain stability while achieving comprehensive reliability testing through controlled dynamic operation
Solution Approach 2:
The device is divided into independent functional modules including the curling component, movable part, transmission mechanism, and guide rail system, allowing each module to perform its specific function while maintaining overall device stability during repeated testing operations
