Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding force of the wearable device is increased to improve fit stability, then the device remains more securely attached, but user comfort deteriorates due to excessive pressure
Solution Approach 1:
The patent implements dynamic adjustment of the holding force based on real-time detection of user state (motion state, biological information). The holding force is not fixed but changes adaptively to match the user's current activity level and physical condition, resolving the contradiction between maintaining stable fit and preventing discomfort.
Solution Approach 2:
The system changes the holding force parameter according to detected usage states. When the user is stationary or engaged in low-intensity activities, the holding force is reduced for comfort. When motion intensity increases or stability is needed, the holding force is increased, thus adapting the parameter to resolve the contradiction between stability and comfort.
2Measurement precision
If the holding force is dynamically adjusted based on motion state, then fit accuracy improves, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The patent utilizes existing sensors in the wearable device (motion sensors, biological information sensors) for multiple purposes: not only for tracking user activity but also for determining the appropriate holding force. This multi-functional use of existing components achieves fit accuracy without proportionally increasing device complexity.
Solution Approach 2:
The system uses the wearable device's own sensors to automatically determine the user state and adjust the holding force without requiring external input or complex control systems. The device serves itself by using its existing capabilities to optimize its own performance, minimizing additional complexity.
3Object-affected harmful factors
If the holding force is restricted based on biological information, then user safety improves, but the adaptability of the device decreases
Solution Approach 1:
The patent applies different holding force restrictions based on specific biological information indicators (e.g., heart rate, temperature). Rather than applying a uniform restriction, the system adjusts the holding force locally according to which biological parameter indicates a safety concern, preserving adaptability while ensuring safety.
Solution Approach 2:
The holding force restriction is not a fixed limit but dynamically adjusts based on real-time biological information. The system monitors multiple biological parameters and adapts the holding force accordingly, maintaining both safety and adaptability through continuous dynamic adjustment rather than static restrictions.
