Solution Overview

Problem

In multi-electrode devices, the close proximity of electrodes and their impedance indicators makes it difficult to determine which indicator corresponds to a specific electrode, leading to ambiguity in assessing the status of electrode connections, especially in limited space.

Innovation Solution

An integrated electrode connector and impedance indicator apparatus with a light-transmitting housing that incorporates both functions in a single device, using a locating post and an LED or similar light-emitting indicator to provide clear and unambiguous status indication of electrode impedance within or outside the operational range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate electrode connectors and impedance indicators are used, then the indicator function is provided, but the space required increases and identification becomes ambiguous

Engineering Contradiction:
Improveidentification clarityVSAvoidspace occupied
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines the electrode connector and impedance indicator into a single integrated unit. The indicator is positioned within or adjacent to the connector housing, allowing both functions to occupy the same spatial footprint. This eliminates the need for separate indicator components and reduces overall space requirements while maintaining clear identification through direct visual association between the indicator and its corresponding connector.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If impedance indicators are placed close to electrodes, then space is saved, but it becomes difficult to determine which indicator corresponds to which electrode

Engineering Contradiction:
Improvespace occupiedVSAvoidindicator-electrode correspondence
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The patent applies local quality by providing visual differentiation features at specific locations. The connector housing includes visual indicators such as colored regions, markings, or transparent portions that correspond to the impedance indicator status. This localized visual information directly at the connector location enables clear identification of which electrode is being indicated without requiring separate indicator components, thus preserving correspondence information while saving space.

Inventive Principle:
Principle #3Local quality

3Reliability

If multiple separate indicators are used for multiple electrodes, then each electrode status can be indicated, but the complexity of the device increases

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by designing the connector housing to serve dual purposes: electrical connection and visual indication. The same structural component (connector housing) that provides the electrical interface also incorporates or houses the impedance indicator. This eliminates the need for separate indicator components for each electrode, reducing overall device complexity while maintaining the ability to monitor multiple electrodes through their respective integrated connectors.

Inventive Principle:
Principle #6Universality (Multi-functionality)
