Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AEDs are bulky, costly, and often not available or intimidating for laypersons to use, limiting their deployment and effectiveness in emergencies.
Innovation Solution
A modular defibrillator system comprising a base unit and an interface unit that can be detachably connected, with optional supplemental battery packs and wireless communication capabilities, allowing for extended functionality and user-friendly operation through synchronized audio-visual instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AEDs are made portable for broader deployment, then availability increases, but weight and bulk increase making them difficult for laypersons to carry
Solution Approach 1:
The AED system is divided into two separate components: a base unit containing the heavy battery and electronic components, and a portable interface unit with display and controls. This segmentation allows the interface unit to be lightweight and easily carried by laypersons, while the base unit remains stationary at deployment locations.
2Reliability
If AED functionality is enhanced for better performance, then reliability improves, but device complexity increases making them intimidating to use
Solution Approach 1:
The interface unit serves as an intermediary between the user and the complex base unit. It provides a simplified user interface with clear visual and audio instructions, shielding users from the complexity of the underlying defibrillation system while maintaining full functionality through wireless communication with the base unit.
3Adaptability or versatility
If AED deployment is expanded to more locations, then availability increases, but cost increases limiting placement
Solution Approach 1:
The base unit can serve multiple locations by being moved between them, while the portable interface units can be distributed widely at low cost. This universal design allows a single expensive base unit to support multiple deployment locations through sharing, reducing the overall cost per location.
4Duration of action of moving object
If battery capacity is increased for extended operation, then duration of action improves, but weight and volume increase
Solution Approach 1:
The battery is segregated into the base unit rather than the portable interface unit. This allows the interface unit to remain lightweight for easy carrying, while the base unit houses the heavy battery that provides extended operation time when the unit is stationed at a location.
