Wearable Fall Detection System for Elderly Independence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elderly individuals living alone face challenges in receiving prompt help during emergencies, such as falls, which can lead to prolonged injury and increased risk of institutional care or mortality, due to their inability to access assistance quickly.
Innovation Solution
A personal safety system comprising a base telephone and wearable device that monitor the user's status, provide notifications, and facilitate emergency responses by ensuring the devices remain in close proximity, detecting falls or other adverse conditions, and automatically alerting caregivers or emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elderly individuals live alone to maintain independence, then autonomy and quality of life are improved, but ability to receive prompt help during emergencies deteriorates
Solution Approach 1:
The system enables elderly individuals to live independently by providing automated fall detection and emergency alert capabilities that operate without requiring the user to actively seek help. The wearable device continuously monitors for falls and automatically triggers emergency responses, allowing the user to maintain independence while ensuring safety through self-monitoring capabilities.
Solution Approach 2:
The patent introduces a wearable detection device and base station as intermediaries between the elderly individual and emergency services. These devices act as mediators that detect falls, communicate with caregivers or emergency centers, and coordinate help without requiring direct interaction from the elderly person during the emergency event.
2Reliability
If prompt help is provided within one hour of emergency, then likelihood of continuing independent living is improved to 90%, but time required to summon help must be minimized
Solution Approach 1:
The system performs preliminary actions by continuously monitoring for falls and having emergency contact information pre-configured in the base station. When a fall is detected, the system immediately triggers pre-programmed emergency responses, eliminating delays associated with the victim attempting to call for help or caregivers realizing the emergency situation.
Solution Approach 2:
The patent implements feedback mechanisms where the wearable device continuously monitors for falls and provides immediate feedback to the base station and caregivers. This real-time feedback system ensures that help is summoned promptly upon detection of an emergency, reducing the time lag between incident occurrence and emergency response activation.
3Reliability
If multiple monitoring functions are integrated into wearable device, then emergency detection capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the monitoring system into two segments: a simple wearable device that performs only fall detection and a base station that handles complex processing, communication, and coordination functions. This segmentation allows the wearable component to remain simple and comfortable for continuous wear while the base station manages the complexity of multiple monitoring functions and emergency response coordination.
