Wearable Device Segmentation for Skin Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable body-associated devices face challenges such as skin irritation, frequent application and removal burdens, and intrusiveness, making long-term wear uncomfortable and inconvenient.
Innovation Solution
A wearable personal body-associated device with a housing, adhesive layer, and electronic module that includes a flexible design, hydrogel pockets, and a waterproof configuration, allowing for comfortable adhesion and communication of physiological parameters while minimizing irritation and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If adhesive-based body associated devices are worn for long-term monitoring, then continuous physiological data collection is improved, but skin irritation and discomfort increase
Solution Approach 1:
The device is divided into multiple independent components: a reusable housing containing electronics and a disposable adhesive patch. This segmentation allows the adhesive portion to be replaced frequently to prevent skin irritation, while the expensive electronic housing can be reused, thus extending overall device duration without continuous skin contact issues
Solution Approach 2:
The adhesive patch portion is designed as a disposable, low-cost component that can be applied and removed multiple times before disposal. This allows users to frequently更换 the adhesive portion to prevent skin irritation while maintaining continuous monitoring through the reusable housing
2Duration of action of moving object
If adhesive-based body associated devices are worn for long-term monitoring, then continuous physiological data collection is improved, but the burden of frequent application and removal increases
Solution Approach 1:
The device separates the complex electronic housing from the simple adhesive patch. The patch portion is designed for easy application and removal by users, while the housing remains stationary or is applied less frequently, reducing the overall burden of frequent manipulation
Solution Approach 2:
The adhesive patch is designed to be easily applied and removed by the user without requiring technical expertise or assistance. The self-adhesive nature and simple design enable users to independently manage the wearable portion, reducing operational burden
3Strength
If rigid housing is used for body associated device, then structural integrity and protection of electronics are improved, but comfort and flexibility during wear deteriorates
Solution Approach 1:
The device separates the rigid protective housing (which remains outside or is applied infrequently) from the flexible adhesive patch (which contacts the skin). This segmentation allows the rigid housing to provide structural integrity and protection without continuously causing discomfort to the wearer
Solution Approach 2:
The adhesive patch portion utilizes flexible, thin-film materials that can conform to body contours and move with the skin, providing comfort during wear. The rigid housing provides protection when not in direct contact with the skin or when applied as a protective overlay

AI summary
A body associated device comprises a housing, an adhesive layer configured to be applied to a body of a living subject, and at least one standoff located between the housing and the adhesive layer. An electronic module may be located within the housing of the body associated device. A personal communication system comprises a body associated device including an electronic module and further comprises a feedback portion coupled to the housing and to the electronic module. The feedback portion is configured to communicate information between the living subject and the body associated device. An external local node is operative to provide at least one of transmit communications to and receive communications from the body associated device.
