Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wearable devices include basic sensors for data collection, then user-associated information can be provided, but the devices lack the capability to identify specific tapping patterns for functional activation
Solution Approach 1:
The patent replaces complex mechanical pattern recognition systems with sensor-based detection. Sensors detect tapping patterns through mechanical signals (vibrations, accelerations) and convert them into electrical signals for processing, simplifying the overall system while maintaining pattern identification capability
Solution Approach 2:
The patent utilizes changes in physical parameters (acceleration, vibration frequency, time intervals) detected by sensors to identify different tapping patterns. By monitoring multiple parameters simultaneously, the system can distinguish between different user intentions without requiring complex mechanical structures
2Ease of operation
If the wearable device monitors tapping patterns continuously, then user interactions can be detected, but energy consumption increases
Solution Approach 1:
The patent implements periodic sampling of sensor data rather than continuous monitoring. The processor checks for tapping patterns at specific time intervals, allowing the device to remain energy-efficient while still detecting user interactions when they occur
Solution Approach 2:
The system automatically detects and responds to tapping patterns without requiring continuous user input or manual activation. Once a tapping pattern is detected, the device autonomously triggers the associated function, reducing the need for continuous operational states
