AED Single Treatment Battery Segmentation for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated external defibrillators (AEDs) have limited battery life, are cumbersome and expensive, leading to reduced availability and increased maintenance costs, and often remain unknown or inaccessible in emergency situations, decreasing the chances of timely intervention during atrial fibrillation events.
Innovation Solution
The development of automated external defibrillator systems with a single treatment battery and a charging device that can couple to external power sources, such as vehicle batteries or USB ports, to maintain power reserves and extend battery life, allowing for compact, affordable, and widely deployable AEDs that can be easily located and accessed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a large capacity battery is used to provide five years of battery life and 200 uses, then the AED can operate for extended periods, but the device becomes cumbersome and expensive
Solution Approach 1:
The battery system is segmented into a small onboard battery for immediate use and an external power source for recharging. The onboard battery only needs to sustain the AED for a single treatment scenario, dramatically reducing its capacity and weight requirements while maintaining operational functionality.
Solution Approach 2:
The external power source performs preliminary charging of the onboard battery before treatment scenarios occur. This allows the onboard battery to be small since it only needs to last for one treatment, while the recharging function is handled in advance by the external power source.

3Weight of stationary object
If a small onboard battery is used for single treatment scenarios, then the device becomes compact and affordable, but the battery must be replaced frequently
Solution Approach 1:
The system implements self-service through automatic recharging. The charging device automatically couples to the onboard battery when power levels are low and recharges it without requiring manual intervention or battery replacement, eliminating maintenance burden while allowing the use of small batteries.
Solution Approach 2:
The charging device acts as an intermediary between the external power source and the onboard battery. It automatically manages the recharging process, coupling to the battery when needed and transferring power, thereby eliminating the need for manual battery replacement while enabling the use of small batteries.
4Adaptability or versatility
If AEDs are deployed widely in various locations, then availability increases, but people may not know where to find them in emergencies
Solution Approach 1:
The AED incorporates visual indicators such as LED lights that change color or illuminate to indicate device status, availability, and location. These visual signals make the AED easily locatable in emergency situations while allowing flexible deployment in various locations throughout a facility.
