Wearable Safety Device with Gesture-Based Distress Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency alert devices require users to manually press a button or be in close proximity to a speakerphone, which can be difficult in emergency situations, especially for users who are severely injured or away from the device.
Innovation Solution
A wearable device that detects distress signals through button presses, gestures, or environmental changes, sending alerts with location information to registered emergency contacts via SMS and email, using GPS and GPRS modules to ensure accurate location tracking and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wearable device with base unit and speakerphone is used, then emergency alert functionality is provided, but the user must be in close proximity to the speakerphone to communicate effectively
Solution Approach 1:
The patent replaces the mechanical speakerphone communication system with an electronic audio recording and transmission system. The microphone records the user's voice, the processor encodes it into digital signals, and the transmitter sends it wirelessly to the remote location, eliminating the need for physical proximity to a speakerphone.
Solution Approach 2:
The patent introduces an intermediary communication system consisting of the microphone, processor, and wireless transmitter that mediates between the user's voice and the remote recipient. This intermediary system allows communication over distance without requiring direct line-of-sight or physical proximity.
2Device complexity
If manual button pressing is required to send alerts, then the device structure is simple, but the user cannot activate the device when severely injured
Solution Approach 1:
The patent implements self-service functionality where the device automatically detects distress situations without requiring user activation. The sensor system continuously monitors for fall patterns, and the processor automatically triggers the alert transmission when a fall is detected, allowing the device to save itself in emergency situations.
Solution Approach 2:
The patent replaces the manual mechanical button-pressing system with an automated sensor-based detection system. Accelerometers and gyroscopes detect fall patterns, and the processor automatically initiates alert transmission, eliminating the need for manual intervention when the user is incapacitated.
3Measurement precision
If GPS and GPRS modules are added for automatic location tracking and alert transmission, then location accuracy is improved, but device complexity increases
Solution Approach 1:
The patent employs a microcontroller that performs multiple functions: it processes sensor data from accelerometers and gyroscopes, manages GPS location tracking, controls GPRS communication, and coordinates alert transmission. This multi-functional approach consolidates several specialized components into a single integrated unit, reducing overall device complexity.
Solution Approach 2:
The patent combines the GPS module, GPRS module, sensor processing, and alert transmission functions into an integrated system managed by a single microcontroller. This merging of functions reduces the number of separate components and simplifies the device architecture while maintaining high location tracking accuracy.

AI summary
A precise, gesture-based, safety monitoring system, method and device. The present invention comprises a controller, wherein the controller upon detection of a distress signal, sends an alert signal along with the Location information of the user to a Remote Server. The Remote Server, upon receiving an alert signal sends an SMS and e-mail along with the Location information to a Mobile device of the registered emergency numbers of the user and responds in real-time.
