Incorporating an integrated electrode coupler that allows for additional electrodes to be connected via extension cables, providing an electrical pass-through connection without interference from existing electrodes, enabling flexible adjustment of the number of leads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed number of electrodes are used in ECG systems, then device simplicity and ease of operation are maintained, but adaptability to different procedures and patient characteristics deteriorates
Solution Approach 1:
The ECG system is segmented into modular components: a base ECG device with a fixed number of electrodes, and separate extension cables with additional electrodes that can be selectively connected. This allows the system to be divided into functional modules that can be independently configured based on procedure requirements, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The system transitions from a static fixed-electrode configuration to a dynamic configurable system where extension cables can be connected or disconnected based on the specific ECG procedure and patient needs. This dynamic adaptability allows the same base device to serve multiple procedural requirements without increasing inherent device complexity.
2Adaptability or versatility
If extension cables and additional electrodes are added to increase electrode count, then adaptability improves, but device complexity and potential signal interference increase
Solution Approach 1:
Extension cables serve as intermediary components between the base ECG device and additional electrodes. These cables provide standardized connection interfaces that simplify the integration of additional electrodes without requiring modifications to the base device, thereby increasing adaptability while managing connection complexity through standardized intermediate components.
3Quantity of substance
If multiple extension cables are connected to the same coupler, then electrode count increases, but signal interference between cables may occur
Solution Approach 1:
Each extension cable and its corresponding coupler are designed with specific localized electrical characteristics that ensure isolated signal paths. The coupler provides separate connection points for each cable, creating locally optimized signal transmission paths that prevent interference between simultaneously connected extension cables, thereby maintaining signal integrity while allowing multiple electrodes to be connected.

AI summary
Methods and systems are provided for selectively increasing an electrode count in a bio signal monitoring system via an extension connector. In an example, a bio signal monitoring system may comprise an integrated electrode coupler configured to be selectively connected to one or more removable electrodes via one or more corresponding extension cables. In this way, electrodes may be added or removed from the bio signal monitoring system based on a monitoring process selected.
