A bioelectrode design featuring a substrate plate with through holes and electrode parts with protruding connection terminals and conductive layers, allowing for adjustable distance between connection terminals and independent replacement of electrode parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the distance between connection terminals is fixed during manufacture, then manufacturing precision is improved, but adaptability to different living body sites deteriorates
Solution Approach 1:
The connection terminals are made movable relative to each other within the holder by allowing movement in the thickness direction of the holder. This dynamic adjustment capability enables the distance between connection terminals to be changed after manufacture, resolving the contradiction between fixed manufacturing precision and adaptability to different living body sites.
2Reliability
If the entire pad is replaced when electrodes are consumed, then reliability is maintained, but loss of time and loss of substance increase
Solution Approach 1:
The pad is divided into replaceable electrode parts that can be individually removed and replaced. When electrodes are consumed, only the affected electrode parts need to be replaced rather than the entire pad, reducing time loss and material waste while maintaining measurement reliability.
Solution Approach 2:
The electrode parts are designed to be disposable while the holder and connector are reusable. This allows the worn electrode parts to be discarded and replaced with new ones, while the remaining functional components are recovered and reused, minimizing overall loss of time and substance.
3Ease of operation
If multiple electrode parts are integrated in one main body, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The electrode assembly is segmented into multiple independent electrode parts that can be handled separately while remaining integrated in the holder. This segmentation allows for easier handling and replacement of individual electrodes without significantly increasing overall device complexity, as the modular structure maintains simplicity in the connector and holder designs.

AI summary
Provided is a bioelectrode including: a substrate plate having a plurality of through holes spaced apart from each other; a plurality of electrode parts; and a fixing plate mounted to a protruding portion of a connection terminal. Each electrode part includes: a covering layer; a connection terminal which is conductive and passes through the covering layer; and a conductive gel layer which is electrically connected to the connection terminal, and is to be brought into contact with a living body. The connection terminal includes a protruding portion protruding from the covering layer, and the protruding portion passes through one of the plurality of through holes of the substrate plate. A size of each of the plurality of through holes of the substrate plate is a size that allows the protruding portion of the connection terminal to be inserted therethrough, and is smaller than a size of the fixing plate.
