Disposable Defibrillator Electrode Assembly with Integrated Power Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable defibrillators require multiple complex steps for operation, including applying a power source, attaching electrodes, and turning on the device, which can be cumbersome for lay users in public settings.
Innovation Solution
A disposable electrode assembly that integrates the power source and electrodes, allowing for a single action to power and activate the defibrillator by incorporating batteries within the electrode assembly and using a connector system that automatically completes the power circuit when the electrodes are applied, eliminating the need for separate battery management and simplifying the operation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate battery and electrode assembly is used, then battery management can be monitored, but operation becomes complex requiring multiple steps
Solution Approach 1:
The patent combines the battery assembly and electrode assembly into a single integrated unit. The battery housing serves dual purposes as both power source enclosure and electrode carrier, eliminating the need for separate battery installation and electrode attachment steps. This merging directly reduces operational complexity while maintaining battery management capabilities.
Solution Approach 2:
The battery housing is designed to perform multiple functions simultaneously: it houses the battery cells, provides structural support for the electrodes, serves as the connector interface with the defibrillator, and acts as the protective enclosure. This multi-functionality eliminates the need for separate components and simplifies the overall operation to a single action.
2Reliability
If multiple steps are required for operation, then battery management can be monitored, but readiness in public situations is reduced
Solution Approach 1:
The battery and electrodes are pre-assembled and pre-tested as a single integrated unit before use. All connections are pre-established within the sealed housing, so when the unit is attached to the defibrillator, everything is already prepared and connected. This preliminary preparation ensures immediate readiness in public situations without requiring step-by-step assembly.
3Ease of operation
If disposable electrodes are used, then ease of operation is improved, but battery management becomes separate and complex
Solution Approach 1:
The patent merges the previously separate battery and electrode assemblies into a single integrated disposable unit. The battery housing simultaneously serves as the electrode carrier and power source enclosure, eliminating the complexity of managing separate battery installations while maintaining the ease of disposable electrode usage.
