Electromedical Adapter for Coiled Electrode Connection

Solution Overview

Problem

Coiled electrodes, while flexible and resistant to fracture, have higher electrical resistance and are more complex and expensive to produce due to their winding, whereas uncoiled electrodes are less flexible and less resistant to fracture.

Innovation Solution

An electromedical adapter that connects a coiled electrode portion to an uncoiled electrode portion using contact elements arranged on a base body, allowing the coiled conductor to radially surround and contact the adapter, thereby establishing a stable and cost-effective electrical connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If coiled electrodes are used to improve flexibility and fracture resistance, then flexibility and fracture resistance are improved, but electrical resistance increases and production complexity increases

Engineering Contradiction:

Improvefracture resistanceVSAvoidproduction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electrode is divided into two separate portions: a coiled electrode portion for flexibility and fracture resistance, and an uncoiled electrode portion for lower electrical resistance. The adapter connects these two portions, allowing each to fulfill its specific function without compromise.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An adapter serves as an intermediary component between the coiled and uncoiled electrode portions. This adapter simplifies the connection process and enables the combination of both electrode types without requiring complex integrated manufacturing.
