Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex procedures are used for switching time correction modes, then time correction accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements dynamic mode switching based on the duration of switch pressing. A short press (first period) triggers one correction mode, while a long press (second period greater than first period) triggers another correction mode. This dynamic response to user input allows the system to adapt its behavior based on the intensity of the user's action, providing both ease of operation through simple gestures and accurate time correction through mode-specific processing.
2Adaptability or versatility
If multiple time correction modes are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system dynamically selects between multiple time correction modes based on the measured duration of switch input. The processor measures the period during which the switch accepts input and determines which correction mode to execute. This dynamic selection mechanism provides adaptability for different user needs while maintaining a simple unified interface, avoiding the complexity of multiple separate controls.
Solution Approach 2:
The patent changes the parameter of switch input duration to select between different correction modes. By varying the time parameter of the user's interaction (short press vs. long press), the system accesses different correction functionalities. This parameter-based selection simplifies the device interface while maintaining multiple correction modes, as users only need to interact with a single switch in different ways.
3Ease of operation
If simple switch manipulation is used, then ease of operation is improved, but time correction precision may deteriorate
Solution Approach 1:
The system uses dynamic threshold-based processing of switch input duration to maintain both simplicity and precision. The processor measures the exact period of switch activation and compares it against predefined time thresholds to determine the appropriate correction mode. This dynamic measurement and comparison ensure accurate time correction while maintaining simple user interaction, as the system internally handles the precision requirements without exposing complexity to the user.
