Conductive Thread Wearable for Automatic Fall Detection

Solution Overview

Problem

Current medical alert systems require user interaction to initiate emergency assistance, which can be impossible for individuals who are unconscious or unable to respond after a fall, and they do not detect falls automatically.

Innovation Solution

A wearable IoT device with an accelerometer, control circuitry, and wireless communicator embedded in conductive threading, which detects falls by measuring the rate of fall and automatically sends notifications to medical personnel without user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current medical alert systems require user interaction to initiate emergency assistance, then the system can confirm user intent and avoid false alarms, but the system becomes unusable for individuals who are unconscious or unable to respond after a fall

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The wearable device automatically detects falls using accelerometers and triggers emergency notifications without requiring user interaction. The system monitors motion patterns, identifies fall characteristics (sudden acceleration followed by prolonged inactivity), and autonomously activates emergency assistance, enabling the device to serve itself in critical situations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical button-pressing interaction with an automated sensor-based detection system. Accelerometers measure motion dynamics, and control circuitry analyzes the data to detect fall patterns, substituting the need for manual user activation with automated mechanical sensing and electronic processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If current medical alert systems are passive devices without fall detection capability, then the device complexity is reduced and manufacturing cost is lowered, but the system cannot automatically detect life-threatening events

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The wearable device integrates multiple functions into a single unit: fall detection using accelerometers, location tracking using GPS, communication using cellular modules, and emergency notification transmission. This multi-functional approach enables comprehensive safety monitoring while maintaining a compact, wearable form factor that can be integrated into clothing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the wearable device uses conductive threading interwoven between fabric layers, then the device becomes integrated into clothing and can be worn continuously, but the manufacturing process becomes more complex

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent uses conductive threads woven between fabric layers to create a flexible, wearable circuit board. This thin-film approach allows the electronic components to be integrated directly into clothing fabric, maintaining flexibility and comfort while enabling continuous wear and monitoring capabilities.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A wearable safety device is provided. The wearable safety device is adapted to detect wearer fall events and shock events and transmit automated notifications if such events have been detected. The wearable safety device utilizes an accelerometer or equivalent components to determine a rate of fall associated with a fall event and determine a magnitude of shock associated with a shock event. The accelerometer, transmission component and a microprocessor coupled to both is dimensioned and adapted to be woven between two layers of fabric by conductive thread, thereby enabling an ever present, wearable device to detect when the wearer has dangerously fallen and proactively request assistance.
