Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode pressure on the skin is increased to improve signal stability, then the signal quality is improved, but the user comfort deteriorates due to skin contact discomfort
Solution Approach 1:
The band is designed with dynamic adjustability through the clamping device, allowing the user to modify the tightening force according to their comfort needs while maintaining sufficient signal quality. The band can be dynamically adjusted between loose and tight states
Solution Approach 2:
The wearable element has a specific three-dimensional shape that concentrates the sensor contact area on a localized region of the body, distributing the pressure more effectively and reducing overall discomfort while maintaining signal stability at the sensor location
2Measurement precision
If the sensor is tightly secured to the skin to maintain stable position during movements, then the measurement precision is improved, but the user comfort deteriorates due to restricted movement and discomfort
Solution Approach 1:
The clamping device enables dynamic adjustment of band tension, allowing users to optimize the balance between sensor stability and movement freedom based on their activity level and comfort preferences
Solution Approach 2:
The band material and clamping mechanism allow adjustment of the contact pressure parameter, enabling optimization between signal quality and user comfort for different usage scenarios
3Reliability
If the band is made adjustable and tight to ensure sensor stability, then the device complexity increases due to the clamping device, but the signal quality improves
Solution Approach 1:
The band is divided into segments with the clamping device acting as a separate adjustable component, allowing independent optimization of each part while maintaining overall simplicity
Solution Approach 2:
The clamping device is designed for manual adjustment by the user without requiring additional mechanisms or power sources, maintaining simplicity while providing necessary functionality

AI summary
A sensorized garment is provided. The sensorized garment includes an wearable element on a skin having a hand-tightening or a closure device to securely constrain sensors, for example electrodes to detect electrophysiological signals, during a physical activity. The wearable element has a three-dimensional shape to uniquely define a right side and a left part of a circumferential zone when the wearable element is worn. The sensorized garment further includes a band carried by the circumferential zone, and at least one conductor connected between the sensor and a zone of the sensorized garment.
