Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated into wearable devices, then health monitoring capability is improved, but connection stability with skin deteriorates leading to detachment and motion artifacts
Solution Approach 1:
The patent applies flexible and stretchable materials to create a carrier that conforms to the skin surface and wearable object. This flexible shell structure maintains stable contact between the sensing element and skin during motion, preventing detachment and reducing motion artifacts while preserving measurement accuracy
Solution Approach 2:
The carrier is designed with adjustable and adaptable properties that allow it to dynamically conform to the skin surface and wearable object shape. This dynamic adaptation ensures continuous stable connection during various movements and wearing conditions, resolving the contradiction between connection stability and measurement precision
2Stability of the object's composition
If the carrier is made rigid to support the sensing element, then structural stability is improved, but adaptability to different wearable object shapes deteriorates
Solution Approach 1:
The patent employs flexible and stretchable materials for the carrier that can conform to various wearable object shapes while maintaining structural stability. The material properties allow the carrier to adapt to different curvatures and forms without compromising its ability to support the sensing element securely
Solution Approach 2:
The carrier's physical parameters such as flexibility, stretchability, and conformability are optimized to enable adaptation to different wearable object shapes. These parameter changes allow the same carrier structure to maintain stability across various forms while preserving structural integrity
3Measurement precision
If the sensing element is firmly attached to the skin, then measurement accuracy is improved, but user comfort deteriorates due to irritation
Solution Approach 1:
The flexible and stretchable carrier material provides a comfortable interface with the skin that maintains stable contact for accurate sensing without causing irritation. The soft, adaptable nature of the material reduces harmful mechanical stress on the skin while preserving measurement precision
Solution Approach 2:
The carrier acts as an intermediary between the sensing element and the skin, providing a comfortable interface that reduces direct irritation while maintaining stable contact. This mediator layer ensures accurate signal transmission without the harmful effects of firm direct attachment
