Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a current bending test device is used for book-turning or hinge bending tests, then the device can perform standard bending tests, but it cannot effectively perform bending tests on wing bending products
Solution Approach 1:
The patent employs dynamic carrier components with rotating arms that can adjust their orientation and movement trajectory. The carrier includes a rotating arm that can pivot between horizontal and vertical positions, and a moving arm that follows a curved path, enabling the system to adapt to different bending patterns including wing bending, book-turning, and hinge bending tests
Solution Approach 2:
The bending test device is designed with multiple functional components that can perform various bending test types. The carrier component with its rotating and moving arms, combined with the support component, creates a universal testing platform that can accommodate different product geometries and bending requirements, making it suitable for both standard and wing bending products
2Device complexity
If the bending test device uses fixed carrier components, then the structure is simple, but it cannot simulate the actual bending path of terminal products
Solution Approach 1:
The carrier component incorporates rotating arms with defined rotation shafts that enable controlled movement along specific trajectories. The first rotating arm can rotate around a vertical rotation shaft, and the second rotating arm rotates around its own rotation shaft, creating a dynamic system that replicates the actual bending paths of terminal products while maintaining structural control
Solution Approach 2:
The patent utilizes curved motion paths through the arrangement of rotating arms and support components. The moving arm follows a curved trajectory during rotation, and the support component is positioned to guide the bending along an arc-shaped path, ensuring that the test accurately simulates the rounded bending paths found in actual terminal product usage
3Device complexity
If the bending test device lacks adjustable parameters, then the structure is simpler, but it cannot perform multiple bending cycles with controlled speed and radius
Solution Approach 1:
The control component receives input signals and adjusts the operation of the motor and linkage components accordingly. It can set and monitor bending parameters such as bending speed, bending radius, and number of bending cycles, creating a closed-loop control system that ensures precise execution of test protocols and enables automated multi-cycle testing
Solution Approach 2:
The device is designed to perform repetitive bending cycles through the coordinated rotation of the carrier arms driven by the motor. The control component can specify the number of cycles, and the mechanism automatically repeats the bending motion with consistent parameters, enabling efficient fatigue testing and reliability assessment through periodic action
