Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional separate calibration devices are used to calibrate operating sensors, then calibration accuracy is improved, but device complexity and ease of operation deteriorate due to requiring additional separate devices
Solution Approach 1:
The patent combines the calibration function with the operating sensor device itself. The operating sensor device detects sequences of actuations at different detection positions and uses these detections to calibrate itself, eliminating the need for separate calibration devices. This merging of calibration and operating functions into a single device reduces system complexity while maintaining calibration accuracy.
Solution Approach 2:
The operating sensor device performs self-calibration by detecting actuation sequences from the user and automatically adjusting its detection positions based on these inputs. The device calibrates itself without requiring external calibration equipment or separate user actions, making the calibration process integrated and automatic.
2Measurement precision
If manual calibration procedures are used, then calibration precision can be maintained, but productivity and ease of operation worsen due to requiring separate user activation and calibration steps
Solution Approach 1:
The operating sensor device automatically calibrates itself by detecting actuation sequences during normal operation. The calibration process is triggered automatically when the device detects a predetermined sequence of actuations, eliminating the need for separate manual calibration procedures and improving productivity.
Solution Approach 2:
The device performs calibration as a preliminary action during the first use or after manufacturing, by detecting actuation sequences from the user. This preliminary calibration establishes the detection positions before normal operation begins, ensuring accuracy without requiring subsequent manual calibration steps.
3Device complexity
If fixed detection positions are used in operating sensor devices, then device complexity is reduced, but adaptability to environmental conditions and user interactions deteriorates
Solution Approach 1:
The patent implements dynamic detection positions that can adjust based on detected actuation sequences and environmental conditions. The operating sensor device determines detection positions dynamically during calibration and operation, allowing adaptation to different users and environments while maintaining reasonable system complexity through algorithmic control.
Solution Approach 2:
The device changes its detection position parameters based on detected actuation sequences and environmental feedback. By adjusting the detection position parameters dynamically, the system adapts to different users and conditions without requiring complex hardware modifications.
