Fall Detection Safety System for Personal Protective Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal protective equipment (PPE) for working at great heights faces challenges in efficiently managing fall events and unconsciousness, particularly in ensuring timely rescue and maintaining equipment reliability.
Innovation Solution
A safety system integrated with PPE, featuring wireless communication, sensors (acceleration and orientation), and evaluation/ notification means, which determines fall or unconsciousness events and alerts a rescue coordination center, while also supporting equipment inspection and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal protective equipment with shock-absorbing elements is used to intercept falls, then the person is protected from major injuries, but the forces occurring in a fall event reach levels many times the weight force and put the body, equipment and anchor point under enormous strain
Solution Approach 1:
The patent applies beforehand cushioning by implementing a safety system that continuously monitors fall risks and prepares rescue measures before actual fall events occur. Sensors detect potential fall conditions and trigger preventive actions, cushioning the impact of future fall events by having rescue systems pre-positioned and activated.
Solution Approach 2:
The patent implements feedback mechanisms through continuous monitoring of fall events using sensors that detect acceleration changes, orientation shifts, and impact forces. This feedback loop provides real-time information about fall conditions to rescue coordination systems, enabling dynamic adjustment of rescue measures based on actual fall parameters.
2Loss of time
If the falling person is monitored for fall events and loss of consciousness, then timely rescue can be initiated, but the person may be unable to free himself due to position or injuries and needs help from third persons
Solution Approach 1:
The patent applies self-service by implementing autonomous monitoring systems that automatically detect fall events and loss of consciousness without requiring manual input from the fallen person. The system autonomously triggers rescue alerts and coordinates rescue measures, enabling the safety system to serve itself in detecting and responding to emergencies.
Solution Approach 2:
The patent introduces an intermediary rescue coordination system that acts as a mediator between the fallen person and third-person rescuers. This intermediary system receives data from sensors, processes fall event information, and coordinates rescue resources, bridging the gap between the incapacitated person and external help.
3Reliability
If the personal protective equipment is subject to regular inspections, then equipment reliability is maintained, but the inspection process requires time and resources
Solution Approach 1:
The patent replaces manual mechanical inspection processes with electronic sensor-based monitoring systems. Acceleration sensors, orientation sensors, and other electronic devices continuously monitor equipment status, substituting traditional manual inspection methods with automated electronic detection that provides real-time equipment health data without requiring periodic manual intervention.
Solution Approach 2:
The patent implements continuous monitoring of equipment status through sensor systems that operate without interruption, replacing discontinuous periodic inspections with continuous surveillance. This ensures equipment reliability is maintained at all times while eliminating the downtime associated with scheduled manual inspections.
