Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of functional instructions is required, then the system can execute precise functions, but the operation process becomes cumbersome and user experience deteriorates
Solution Approach 1:
The system automatically detects body movements and executes corresponding functions without requiring manual input from the user. The sensing unit continuously monitors user movements and the control unit automatically translates them into functional instructions, making the system serve itself by eliminating the need for explicit user commands.
Solution Approach 2:
The patent replaces manual mechanical input operations with automated sensing and recognition systems. Acceleration sensors, inclination sensors, and vibration sensors detect body movements, and the control unit processes these signals to determine user intent, substituting the manual input mechanism with an automated sensing-and-recognition system.
2Ease of operation
If body movement sensing is added to enable automatic function execution, then ease of operation improves, but device complexity increases
Solution Approach 1:
The sensing unit is designed to detect multiple types of body movements (acceleration, inclination, vibration) and the control unit is programmed to recognize various movement patterns and map them to different functions. This multi-functional design allows a single sensing unit to handle diverse input methods, reducing the need for separate specialized components for each function.
Solution Approach 2:
The patent combines multiple sensing functions (acceleration sensing, inclination sensing, vibration sensing) into a single integrated sensing unit. The control unit merges the processing of different sensor signals and consolidates the decision-making logic for function execution, reducing overall system complexity through integration rather than separate independent systems.
