Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sensor and actuator integration is added to adjust force intensity levels, then manufacturing precision of key actuation is improved, but device complexity increases
Solution Approach 1:
The system employs sensors to detect key motion and provides feedback signals to the processor, which then adjusts actuator output accordingly. This closed-loop feedback mechanism enables precise calibration of force intensity levels applied to keys, resolving the contradiction by achieving high manufacturing precision through intelligent control rather than mechanical complexity
Solution Approach 2:
The patent replaces traditional mechanical calibration methods with an electro-mechanical system using actuators and sensors. Instead of manually adjusting mechanical components, the system uses electronic control to apply precise force intensity levels, reducing mechanical complexity while improving actuation precision
2Ease of operation
If calibration methods are simplified for ease of operation, then ease of operation is improved, but measurement precision of sensor signals deteriorates
Solution Approach 1:
The system performs self-calibration by automatically comparing sensor signals against predetermined reference values and adjusting actuator outputs accordingly. This self-service approach eliminates the need for manual calibration procedures, improving ease of operation while maintaining high measurement precision through automated algorithms
Solution Approach 2:
The system changes operational parameters dynamically during calibration by adjusting force intensity levels and comparing sensor responses. By varying parameters such as actuator activation patterns and sensor threshold values, the system achieves accurate calibration without requiring complex manual measurement procedures
