Electrotherapy Electrode Layout for Easy Removal and Peel Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical treatment devices are difficult to remove entirely from treatment sites, especially when disposed on the rear back or inside clothing, and are prone to peeling due to gravitational stress and displacement of electrode portions.
Innovation Solution
The device features a configuration with first and second electrode portions spaced apart, each having peeling starting points, and a gripping portion to apply simultaneous peeling forces, minimizing peeling due to gravity and stress, and allowing easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical treatment device is peeled off using the pinch tab from the end portion side of the conductive adhesive sheet, then the device can be removed, but it is difficult to entirely remove the device from the treatment site and difficult to find the pinch tab when disposed on the rear back or inside clothes
Solution Approach 1:
The pinch tab is extracted from the conductive adhesive sheet and repositioned to extend from the second end of the main body in the second direction. This separation makes the pinch tab more accessible and visible when the device is disposed on the rear back or inside clothes, while still enabling effective removal of the entire device from the treatment site.
2Weight of moving object
If the treatment device main body is heavy, then the device provides sufficient treatment force, but stress is likely to be applied to the pair of conductive adhesive sheets in a direction in which gravity acts, causing the sheets to peel off from the upper side
Solution Approach 1:
The first and second electrode portions are arranged in a second direction that intersects with the first direction (the direction of gravitational stress). This orthogonal arrangement distributes the stress from the heavy main body across different dimensions, preventing the conductive adhesive sheets from peeling off from the upper side while maintaining sufficient treatment force.
3Device complexity
If the first electrode portion and second electrode portion are disposed close to each other, then the device structure is compact, but the electrode portions are more likely to peel off when stress is applied from one side or the other
Solution Approach 1:
The first electrode portion and second electrode portion are disposed at different positions in the second direction, which intersects with the first direction. This spatial arrangement in another dimension provides better stress distribution and peeling resistance while maintaining a compact overall structure, as the electrodes are not simply spaced apart in the first direction but rather positioned orthogonally.

AI summary
An electrical treatment device includes a main body portion that includes a first outer edge portion and a second outer edge portion facing each other in a first direction in a plan view, and a first electrode portion, and a second electrode portion. The first electrode portion and the second electrode portion are spaced apart from each other in the first direction and disposed to cause at least a central portion of the main body portion to be located therebetween. The first electrode portion includes a first peeling starting portion, and a first line located on a side of the second electrode portion. The second electrode portion includes a second peeling starting portion, and a second line located on a side of the first electrode portion and facing the first line in the first direction.
