Solution Overview
Problem
Existing AEDs are not widely accessible, require specialized training, and have high user thresholds due to their bulkiness and cost, limiting their effectiveness in public emergencies.
Innovation Solution
A mobile AED system that integrates with a smartphone or similar device, utilizing existing hardware for operation, includes a defibrillator unit connected via USB-C, and uses an app for user interface, providing guidance and control, and can connect to power banks or external sources, with pads equipped with accelerometers and an electrical shock circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional AEDs are used, then defibrillation function is provided, but device size and cost are large, reducing accessibility
Solution Approach 1:
The patent combines the defibrillator with a smartphone, merging the essential defibrillation function with a commonly carried device. The smartphone serves as the control unit while external electrodes perform defibrillation, creating a compact integrated system that maintains effectiveness while dramatically reducing size.
Solution Approach 2:
The smartphone-based defibrillator leverages the universal presence of smartphones in modern society. By using the smartphone's existing battery, processor, and display, the system achieves multi-functionality where a single device (smartphone) serves both as a communication tool and a life-saving defibrillator, eliminating the need for dedicated bulky AED equipment.
2Reliability
If traditional AEDs are used, then defibrillation is possible, but specialized training is required, increasing user complexity
Solution Approach 1:
The system employs automated rhythm analysis and shock delivery decisions through the smartphone's processor, which automatically analyzes ECG data from the electrodes and determines when defibrillation is needed. This self-service automation eliminates the need for users to have specialized medical training, as the device makes critical decisions autonomously based on algorithmic analysis.
Solution Approach 2:
The smartphone provides real-time feedback through its display and interface, guiding users through the defibrillation process step-by-step. The system continuously monitors heart rhythm and provides visual and tactile feedback to confirm proper electrode placement and shock delivery, making the operation intuitive for untrained users.
3Reliability
If traditional AEDs are deployed, then emergency response is provided, but cost and bulkiness limit widespread availability
Solution Approach 1:
Instead of manufacturing and deploying numerous expensive traditional AED devices, the patent creates a software-based defibrillation system that can be copied and distributed as a mobile application to smartphones. This digital copying approach eliminates manufacturing costs for hardware while maintaining full defibrillation functionality, enabling widespread distribution at minimal cost.
Solution Approach 2:
The external electrodes used with the smartphone defibrillator are designed as disposable, low-cost components that can be mass-produced and distributed freely. This approach replaces expensive reusable AED hardware with affordable single-use electrodes, dramatically reducing the barrier to widespread deployment while maintaining clinical effectiveness.

AI summary
A method for performing CPR with a mobile defibrillator (AED) unit can include detecting, via an application on a user device, a connection of a mobile AED unit to the user device; detecting, via the application, that pads have been attached to a subject, the pads comprising at least one accelerometer; recording, via the application, EKG measurements of the subject made by the pads; receiving accelerometer data from the at least one accelerometer; analyzing the accelerometer data to determine a breathing pattern of the subject; and based on the determined breathing pattern, initiating a CPR protocol.
