Motion Actuated AED Communicator for Rapid Emergency Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable automatic external defibrillators (AEDs) face a conflict between the need for immediate wireless connection to an emergency service center during critical events and the need to conserve battery life, with existing technologies taking over thirty seconds to power up and connect, which is unacceptably long for life-saving situations.
Innovation Solution
A motion-sensitive communicator is developed, combining a wireless phone with a motion sensor and battery, where movement powers up the phone to quickly connect to a wireless network and initiate a call to an emergency service center, and automatically de-powers when not in use to extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the communicator is powered up immediately to enable immediate wireless connection to emergency service center, then connection speed is improved, but battery life is depleted faster
Solution Approach 1:
The motion sensor performs preliminary detection of movement before the wireless phone is activated. When movement is detected, the system prepares for immediate connection by detecting the motion event first, then triggering the power-up sequence, thereby reducing the effective connection time while managing battery usage strategically.
Solution Approach 2:
The system dynamically adjusts its power state based on motion detection. The wireless phone transitions from a powered-down state to an active state only when motion is detected, creating a dynamic response system that balances connection speed needs with battery conservation by being ready to act immediately when needed rather than maintaining constant readiness.
2Use of energy by moving object
If the communicator remains powered down to conserve battery life, then battery life is extended, but connection time increases beyond acceptable limits
Solution Approach 1:
The motion sensor continuously monitors for movement events in advance, so when an emergency situation occurs and the device is moved, the system is already aware of the motion and can immediately initiate the power-up and connection sequence, minimizing the actual delay while the phone remains powered down for battery conservation.
Solution Approach 2:
The motion sensor automatically detects when the defibrillator is moved and triggers the power-up sequence without requiring manual intervention. The system serves itself by detecting its own operational context (movement indicating potential emergency use) and autonomously transitioning to the appropriate power state.
3Reliability
If the wireless phone automatically registers to wireless network upon power up, then connection readiness is improved, but power consumption increases
Solution Approach 1:
The motion sensor performs preliminary detection of movement events before the wireless phone is activated. This preliminary action allows the system to understand the context of power-up (emergency use indicated by movement) versus storage mode, enabling selective activation of network registration only when movement is detected, thereby improving connection reliability when needed while reducing unnecessary power consumption during storage.

AI summary
A motion sensitive communicator (40) employs an assembly of a wireless phone (41), a motion sensor (44) and a battery (45). In operation, the motion sensor (44) power couples the battery (45) to the wireless phone (41) responsive to a sensing of any movement of a portable defibrillator (20) supporting the communicator (40). A power coupling of the battery (45) to the wireless phone (41) automatically activates the wireless phone (41) to register to a wireless network, and an activation of the wireless phone (41) enables the wireless phone (41) to execute a call to an emergency service center over the wireless network responsive to a manual actuation of the wireless phone (41). The battery (45) is power decoupled from the wireless phone (41) responsive to an absence of a call from the wireless phone (41) to the emergency service center within a time period initiated by a power coupling of the battery (45) to the wireless phone (41).
