Wearable Defibrillator Garment with Coded Sizing and Capacitive Electrodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable defibrillators face challenges in accurately positioning electrodes during patient motion, leading to ineffective electrical therapy and discomfort, and patients are reluctant to change and launder support garments due to complexity and perceived difficulty in assembly.
Innovation Solution
A patient-worn energy delivery system comprising a support garment with adjustable shoulder straps and a belt for one-sided assembly, featuring coded zones on a measuring band for sizing, and non-adhesive capacitive electrodes to ensure proper positioning and comfort, reducing the need for skin-irritating substances and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustable shoulder straps and belt with coded zones are used for one-sided assembly, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The garment is divided into modular components including shoulder straps, belt, and coded zones that can be independently adjusted and assembled. This segmentation allows for one-sided assembly while maintaining overall system functionality.
Solution Approach 2:
The coded zones on the measuring band enable patients to independently determine their own garment size without requiring professional assistance. The self-measuring capability empowers users to perform the sizing function themselves.
2Object-generated harmful factors
If non-adhesive capacitive electrodes are used, then object-generated harmful factors are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The adhesive substance is completely removed from the electrode design. Instead of using adhesive-based attachment, the system employs capacitive coupling that requires no skin contact materials, thereby eliminating the source of skin irritation.
Solution Approach 2:
The electrode design transitions from adhesive-based physical attachment to capacitive electrical coupling. This parameter change in the attachment mechanism eliminates skin irritation while maintaining effective electrical contact for sensing and therapy functions.
3Measurement precision
If coded zones on measuring band are implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measuring band is pre-marked with coded zones that correspond to specific garment sizes. This preliminary coding of measurement values allows patients to quickly and accurately determine their size without requiring complex calculations or interpretation.
Solution Approach 2:
The coded zones on the measuring band use visual indicators such as color coding or distinct markings to represent different size ranges. This visual encoding system enables rapid and accurate size determination through simple visual matching rather than complex measurement interpretation.

AI summary
A support garment for a patient-worn energy delivery apparatus. A vest-type garment holds an electrode belt in contact with a wearer's ribcage. A removable electrode harness may be attachable to the support garment to accurately position sensing electrodes on the body of the wearer and energy delivery electrodes for transfer of an electrode therapy pulse to the wearer of the garment. The chest garment includes adjustable shoulder straps and a band to accommodate any body size or shape. One-sided assembly and coding of components facilitates use by a patient. A technique for sizing the support garment is also disclosed.
