Wearable Electrode Oblique Placement for Stable Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electrodes often detach when the wearer bends forward, causing measurement disruptions and discomfort due to tight fastening.
Innovation Solution
The wearable electrode design includes first and second electrodes that contact the skin from the ventral to dorsal sides of the upper body, with attaching positions that descend or ascend as the wearer stands upright, ensuring continuous contact and reducing tension around the waist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable electrode is fastened tightly to prevent detachment, then the electrode remains in contact with the body, but the wearer feels unpleasant and experiences discomfort
Solution Approach 1:
The patent changes the arrangement of electrodes from a horizontal layout to an oblique arrangement extending from the ventral side to the dorsal side of the chest. This dimensional change allows the electrodes to follow the natural curvature of the body and maintain contact through body movements without requiring tight fastening, thereby resolving the contradiction between contact stability and wearer comfort
Solution Approach 2:
The oblique arrangement of electrodes allows the garment to dynamically adapt to body movements such as bending forward. The electrodes are positioned to maintain contact with the skin even when the body changes posture, providing dynamic contact stability without requiring excessive fastening tension that would cause discomfort
2Reliability
If the wearable electrode is fastened tightly to prevent detachment during movement, then the electrode remains in contact with the body, but the garment cannot expand and compress freely around the waist
Solution Approach 1:
By arranging electrodes obliquely from ventral to dorsal sides rather than horizontally, the patent enables the garment to expand and compress naturally around the waist while maintaining electrode contact. This dimensional arrangement accommodates garment flexibility without compromising electrode-st skin contact stability
Solution Approach 2:
The patent applies electrodes at specific oblique positions on the chest that are optimized for maintaining contact during various movements. This localized strategic placement ensures reliable signal acquisition while allowing the rest of the garment to move freely, resolving the contradiction between contact stability and garment adaptability
3Device complexity
If the electrode is positioned horizontally on the chest, then the electrode arrangement is simple, but the electrode detaches when the wearer bends forward
Solution Approach 1:
The patent transitions from a simple horizontal electrode arrangement to an oblique arrangement extending from ventral to dorsal sides. This dimensional change increases contact stability during body movements like bending forward, while the overall structure remains relatively simple and easy to implement in the garment design

AI summary
A wearable electrode includes an electrode (203) fixed to garment (21) such that the electrode (203) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper left part of the body of a wearer (20), and an electrode (204) fixed to the garment such that the electrode (204) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper right part of the body of the wearer (20). The electrodes (203, 204) are installed such that the attaching positions gradually descend from the ventral side to the dorsal side with the wearer (20) standing upright, or the attaching positions gradually ascend from the ventral side to the dorsal side with the wearer (20) standing upright.
