Adjustable Sensor Carrier for Stable Skin Contact in Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices with integrated sensors face challenges in maintaining stable connections with the user's skin, leading to potential detachment and motion artifacts, which affect measurement accuracy and user comfort.
Innovation Solution
A detection module with an adjustable carrier that conforms to the shape of a wearable object, supporting a sensing element that remains affixed to the skin through a flexible and stretchable material, allowing for secure attachment and detachment as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into wearable devices, then health monitoring capability is improved, but connection stability with skin deteriorates
Solution Approach 1:
The sensing element is separated from the wearable device body and mounted on an independent adjustable carrier. This segmentation allows the sensing element to be optimally positioned and adjusted for stable skin contact, while the carrier can be independently tuned for different wearable shapes, resolving the contradiction between health monitoring capability and connection stability.
2Measurement precision
If sensing element is fixed rigidly, then measurement accuracy is improved, but motion artifacts increase
Solution Approach 1:
The carrier is designed with adjustable properties that allow it to adapt dynamically to different wearable configurations and skin contours. This dynamic adjustability enables the sensing element to maintain stable skin contact for accurate measurements while accommodating body movements, thereby reducing motion artifacts.
3Stability of the object's composition
If carrier is made rigid, then structural stability is improved, but adaptability to different wearable shapes deteriorates
Solution Approach 1:
The carrier's physical parameters (such as flexibility, curvature, or dimensional characteristics) are made adjustable to match different wearable object shapes. This parameter adjustability allows the carrier to adapt to various wearable configurations while maintaining sufficient structural stability to support the sensing element and ensure reliable skin contact.
