PPE Alert Module With Wireless Speech Identification Outreach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Personal Alert Safety System (PASS) devices in personal protective equipment (PPE) have limited outreach, with alerts typically received only by those in proximity or through specialized applications, restricting the reach of distress signals.
Innovation Solution
A system for PPE articles that includes a memory to store user identification, a safety module to generate alerts based on motion status, and a transceiver unit to wirelessly transmit speech data, enabling wider outreach of distress signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional PASS devices use audible/visual alerts only, then the device complexity is low, but the extent of outreach is limited
Solution Approach 1:
The PASS device is enhanced with multiple alert transmission methods including audible alerts, visual alerts, and wireless speech data transmission. The controller can convert user identification to speech data and transmit it wirelessly through a transceiver unit, enabling the device to reach personnel beyond immediate proximity while maintaining compatibility with existing alert methods
Solution Approach 2:
A wireless transceiver unit and controller are introduced as intermediary components to bridge the gap between the motion sensing module and remote personnel. The controller retrieves user identification from memory, converts it to speech data, and the transceiver unit wirelessly transmits this data to external devices, enabling extended outreach without requiring direct line-of-sight or specialized applications
2Productivity
If PASS devices transmit only proximity-based alerts, then the loss of information is minimal, but the productivity of rescue operations is reduced
Solution Approach 1:
User identification information is pre-stored in the memory device before any emergency occurs. When the motion sensing module detects that the user has been stationary for a predetermined time, the controller immediately retrieves the pre-stored user identification and converts it to speech data for transmission, eliminating delays associated with information gathering during rescue operations
Solution Approach 2:
The system provides feedback to external devices by transmitting speech data containing user identification information. This allows receiving devices to identify which specific user requires assistance, enabling targeted rescue operations and improving overall productivity by reducing the time needed to locate and assist the distressed individual
