Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated external defibrillators (AEDs) are expensive, bulky, and single-function, making them inaccessible and difficult for individuals to use during emergencies, particularly in low- and middle-income categories, leading to reduced chances of survival during cardiac events due to lack of familiarity and improper usage.
Innovation Solution
A compact, multi-functional AED that includes a housing with various ports for charging and jumpstarting, integrated with a smartphone application for guiding users through defibrillation and offering additional functions like phone charging and car battery jumpstarting, utilizing monophasic or biphasic shocks and ECG pads for ventricular fibrillation treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional AEDs are designed with sufficient power for defibrillation, then defibrillation effectiveness is improved, but device size and weight increase making them bulky and inconvenient
Solution Approach 1:
The device separates defibrillation function from other functions, using a dedicated defibrillation module that can be selectively activated. The power source is segmented to provide high power only when defibrillation is needed, rather than continuously powering all features.
Solution Approach 2:
The device dynamically adjusts its power output and operational mode based on detected needs. The processor determines whether defibrillation, charging, or other functions are required, and the power source adapts its output accordingly, providing high power only when necessary for defibrillation.
2Adaptability or versatility
If AEDs are designed with multiple functions, then versatility and cost-effectiveness are improved, but device complexity increases
Solution Approach 1:
The device integrates multiple functions including defibrillation, battery charging (USB and 12V ports), flashlight, and hazard lights within a single unit. The power source serves multiple purposes, and the processor manages different operational modes to provide versatile functionality.
Solution Approach 2:
The processor acts as an intermediary that manages and coordinates different functions. It detects user inputs, determines the appropriate operational mode, and controls the power source and various output devices, thereby managing complexity through centralized control.
3Volume of moving object
If AEDs are made compact and portable, then accessibility and ease of transport are improved, but power delivery capability may be reduced
Solution Approach 1:
The device nests multiple functional components within a compact housing. The power source, processor, defibrillation electrodes, and auxiliary features are integrated in a nested arrangement that maximizes space utilization while maintaining defibrillation capability.
Solution Approach 2:
The device changes its operational parameters based on the detected need. When defibrillation is required, the power source delivers high-power shocks. For other times, it operates in low-power modes such as charging or providing auxiliary functions, thereby maintaining compact size while ensuring adequate power delivery when needed.
4Ease of operation
If AEDs are designed for automated operation, then ease of use by laypeople is improved, but device complexity and cost increase
Solution Approach 1:
The device performs self-diagnosis and automated decision-making through its processor, which detects cardiac rhythms and determines whether defibrillation is needed. The system guides users through automated prompts, reducing the need for extensive user training while managing complexity through intelligent automation.
