Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety equipment monitoring systems face challenges in verifying the proper use and compliance of fall protection equipment, especially in environments with multiple workers using different types of equipment, as direct and ongoing verification is difficult without physical inspection.
Innovation Solution
A fall protection compliance system that includes a connector with a connection sensor assembly using a permanent magnet and magnetometer to detect the presence or absence of a ferromagnetic material, and a short-range wireless communication antenna to identify approved connection structures, providing visual, audio, and tactile indications, and transmitting connection status information to a remote device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct physical inspection is used to verify safety equipment compliance, then measurement precision is improved, but productivity deteriorates due to the time-consuming nature of manual inspections
Solution Approach 1:
The patent replaces manual physical inspection with an automated sensor system that uses magnetometers and RFID readers to detect the presence and status of fall protection equipment components. The connector includes integrated sensors that automatically detect when a harness is properly connected to an anchor point, eliminating the need for manual verification while maintaining accurate compliance monitoring.
Solution Approach 2:
The safety equipment itself performs the verification function through integrated sensors and communication devices. The connector automatically detects connection status, monitors equipment integrity, and transmits compliance data without requiring external inspection, allowing the system to self-verify its own proper usage and compliance status.
2Reliability
If continuous monitoring of multiple workers is implemented, then reliability is improved, but device complexity worsens due to the need for multiple sensors and communication systems
Solution Approach 1:
The connector is designed as a multi-functional device that combines connection hardware, magnetic field sensing, RFID communication, and data transmission capabilities into a single integrated unit. This universal design allows the same device to perform multiple functions including detecting harness connection, verifying anchor point integrity, communicating compliance status, and transmitting data to remote monitoring systems, thereby managing complexity through consolidation rather than proliferation of separate components.
3Productivity
If automated sensor systems are deployed, then productivity is improved by eliminating manual inspections, but device complexity increases due to additional components
Solution Approach 1:
The patent merges the connection structure with monitoring functions by integrating sensors, magnetometers, and communication devices directly into the connector hardware. Rather than adding separate monitoring equipment to existing safety gear, the system combines these functions into a unified connector assembly, thereby improving productivity through automation while managing complexity through integration and consolidation of components.
