Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional testing assemblies are used to test input devices, then the testing process requires manual part replacement when testing conditions change, but this leads to reduced testing efficiency and increased testing time
Solution Approach 1:
The patent applies the dynamics principle by implementing an actuator that can dynamically adjust the pressing force applied to the under-test object. The actuator changes the magnitude of the applied force and the distance between the testing assembly and the under-test object, allowing the testing system to adapt to different testing conditions without manual intervention. This dynamic adjustment capability resolves the contradiction by enabling both adaptability and continuous operation.
Solution Approach 2:
The patent implements parameter changes by using sensors to detect force and vibration data, and an actuator to modify the pressing force parameters. The system can change the magnitude of the applied force and the distance parameters automatically, allowing different testing conditions to be met without replacing parts. This resolves the contradiction between adaptability and productivity by enabling parameter adjustment without manual intervention.
2Adaptability or versatility
If multiple stations are equipped to test multiple functions, then various testing functions can be performed, but the device complexity and space requirements increase
Solution Approach 1:
The patent applies the universality principle by designing a testing assembly that can perform multiple testing functions using a single configuration. The assembly includes sensors for detecting force data and vibration data, and an actuator for adjusting pressing force, allowing it to test various input devices (force pads, touch pads, keyboards, mice) with different testing requirements without needing separate dedicated stations. This resolves the contradiction by enabling one assembly to fulfill multiple testing functions.
Solution Approach 2:
The dynamic adjustment capability of the actuator allows the single testing assembly to adapt to different testing functions by changing the magnitude of applied force and distance parameters. This enables one versatile assembly to replace multiple specialized stations, reducing device complexity while maintaining comprehensive testing coverage.
3Adaptability or versatility
If weights are changed to test various products with different pressing forces, then different force requirements are met, but the testing procedure must be stopped and part replacement is required
Solution Approach 1:
The patent implements dynamics by replacing static weight configurations with a dynamic actuator system. The actuator can continuously adjust the magnitude of the applied force during the testing process, allowing the system to meet different pressing force requirements without stopping the test procedure or replacing physical weights. This resolves the contradiction by enabling force adjustment without testing interruptions.
Solution Approach 2:
The patent substitutes the mechanical weight-based force application system with an actuator-driven system. Instead of manually changing physical weights, the actuator electronically controls the applied force, allowing seamless adjustment of pressing forces without manual intervention or testing interruptions. This substitution eliminates the time loss associated with part replacement while maintaining force adaptability.
