Body Electrode Unit With Separable Release Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body electrode units face challenges in attaching multiple electrodes to a body at desired positions accurately, often resulting in unintended positioning and potential failure of the electrode system.
Innovation Solution
A body electrode unit is designed with a release sheet that includes processed parts to facilitate separation and bending, allowing the electrodes to be attached to a body at desired positions by adjusting the connection portions to accommodate different hand sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple electrodes are attached to a single continuous substrate sheet, then the attaching operation becomes easier and can be performed at once, but the substrate sheet may be attached to an unintended position on the body
Solution Approach 1:
The substrate sheet is divided into multiple separable areas or segments, each containing one or more electrodes. This segmentation allows each electrode or group of electrodes to be positioned and attached independently to the body, ensuring accurate positioning while maintaining the ease of simultaneous attachment benefit. The substrate sheet can be torn or separated along predefined lines into individual electrode modules.
Solution Approach 2:
Each electrode is extracted or separated from the continuous substrate sheet onto its own individual liner or carrier. This extraction allows each electrode to be independently positioned and attached to the desired location on the body, eliminating the problem of the entire continuous sheet being attached to an unintended position while still allowing multiple electrodes to be applied in a coordinated manner.
2Manufacturing precision
If electrodes are attached one by one to the body, then precise positioning can be achieved, but the attaching operation becomes more complex and time-consuming
Solution Approach 1:
The substrate sheet is segmented into multiple areas, each containing one or more electrodes on separate liners. This segmentation enables electrodes to be attached in a simplified sequential manner - each segmented area can be peeled and attached independently - while maintaining the precision of individual electrode positioning. The segmentation creates natural attachment units that are easier to handle than a continuous sheet.
Solution Approach 2:
Each electrode is pre-positioned on its own liner or carrier sheet with the correct adhesive gel applied beforehand. This preliminary action of pre-positioning electrodes on separate liners before application to the body allows for precise positioning to be built into the product design, eliminating the need for complex manual positioning during the attachment process while maintaining ease of operation.
3Device complexity
If the substrate sheet is made as a single continuous shape to accommodate multiple electrodes, then the structure is simplified, but it cannot accommodate variations in body size and shape
Solution Approach 1:
The substrate sheet is divided into multiple separable areas or modules, each containing one or more electrodes. This segmentation allows the electrode array to be configured in different patterns and spacings to accommodate various body sizes and shapes. The modular structure can be adapted to different anatomical locations while maintaining overall structural simplicity through standardized segment designs.
Solution Approach 2:
The substrate sheet design incorporates flexibility and adaptability through its segmented structure, allowing it to be configured dynamically for different body sizes and shapes. The separable areas can be arranged or selected based on the specific application requirements, enabling the same basic design to adapt to various anatomical variations while maintaining structural simplicity.

AI summary
A body electrode unit includes a body electrode configured to be attached to a body, and a release sheet to which the body electrode is attached. The body electrode includes at least a first electrode and a second electrode. The first electrode and the second electrode are put together to form a single continuous shape. The release sheet includes a first processed part configured to facilitate at least one of a separation and a bending of the release sheet, the first processed part being provided in a first area between a position at which the first electrode is attached and a position at which the second electrode is attached.
