Touch-Sensor PPE Verification for Automated Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for enforcing the use of personal protective equipment (PPE) in workplaces are time-intensive and inaccurate, failing to ensure proper usage, which leads to on-the-job eye injuries and associated losses.
Innovation Solution
Integration of touch-sensitive sensors into PPE, such as goggles, hard hats, and masks, that communicate with a computing device to verify proper wear and usage, allowing access to restricted areas only when the PPE is correctly worn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection by supervisor is used to verify PPE usage, then compliance can be monitored, but the process becomes time-intensive and inaccurate for users outside visual range
Solution Approach 1:
The PPE system performs self-verification through integrated sensors that automatically detect whether the equipment is properly worn. The sensors monitor contact with the user's body and transmit this information autonomously, eliminating the need for supervisor inspection and enabling continuous reliable verification without time loss.
Solution Approach 2:
The manual mechanical inspection process is replaced with an electronic sensing system. Touch-sensitive sensors and communication devices substitute for the supervisor's visual inspection, providing automated detection of PPE usage status and eliminating the time-consuming manual verification process.
2Measurement precision
If manual inspection is used to verify PPE usage, then some compliance can be checked, but it fails to verify usage for users outside the supervisor's visual range
Solution Approach 1:
Communication devices act as intermediaries between the sensors on PPE and the central monitoring system. These devices transmit sensor data wirelessly, enabling verification of users anywhere in the facility without requiring supervisor proximity or visual contact, thus expanding coverage range while maintaining detection accuracy.
Solution Approach 2:
The verification system transitions from two-dimensional visual inspection to three-dimensional spatial coverage through wireless communication. Sensors and communication devices enable monitoring across multiple dimensions and locations, allowing verification of users outside the supervisor's direct visual range while maintaining precise detection of PPE usage status.
Data Source
AI summary
Systems, methods, and computer-readable and executable instructions are provided for detecting a use of personal protective equipment (PPE). Detecting a use of PPE can include collecting contact data from a number of touch sensitive sensors attached to the PPE. Furthermore, detecting a use of PPE can include determining if the PPE is in proper use based on the collected contact data.
