Sensor-Integrated Safety Harness for Early Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workers in hazardous environments face risks of accidents such as falls and hypothermia, with existing protective measures often failing to prevent injuries or detect dangerous situations in time.
Innovation Solution
A portable protective equipment with integrated sensors that detect dangerous situations before they escalate into emergencies, automatically activating a securing system, such as tensioning safety ropes or deploying airbags, to prevent accidents and maintain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fall protection devices are used to secure people at great heights, then the person is protected from falls, but injuries such as crushing injuries or whiplash injuries may still occur during the emergency situation
Solution Approach 1:
The sensor device detects dangerous situations (such as approaching fall edges or hazardous conditions) before they escalate into full emergency situations. This early detection triggers the securing system in advance, allowing protective measures to be activated before the actual emergency occurs, thereby preventing injuries that would result from reactive protection only.
Solution Approach 2:
The system applies counter-action in advance by automatically activating the securing system when dangerous situations are detected. The sensor device monitors environmental conditions and worker position, and when thresholds are approached (such as near fall edges), the securing system is preemptively engaged to counteract potential harmful effects before they materialize into actual emergencies.
2Object-affected harmful factors
If airbags are deployed to dampen collision shock, then protective cushioning is provided, but the emergency situation has already occurred at the time of activation
Solution Approach 1:
The sensor device continuously monitors environmental conditions and worker position to detect dangerous situations before they become emergencies. When hazardous conditions are identified (such as approaching fall edges or unstable terrain), the system activates protective measures in advance, providing time for the securing system to deploy before the actual emergency occurs, thereby eliminating the time loss associated with reactive protection.
3Extent of automation
If a sensor device is integrated with the securing system to detect dangerous situations, then automatic protection is activated, but the device complexity increases
Solution Approach 1:
The sensor device is integrated directly with the securing system, combining detection and protection functions into a unified system. This merging eliminates the need for separate manual activation mechanisms and intermediate control systems, reducing overall complexity while achieving full automation. The sensor device and securing system operate as a coordinated unit, sharing power supply and control circuits.
Solution Approach 2:
The system is designed to be self-activating, where the sensor device automatically triggers the securing system without requiring external intervention or complex control logic. The sensor device monitors conditions and self-activates the protection mechanism when predetermined dangerous situations are detected, eliminating the need for manual operation or sophisticated decision-making algorithms.

AI summary
Protective equipment for protecting a person from an emergency situation is disclosed. The protective equipment has a securing device, which is portable by the person, having a securing system for protecting the person from an emergency situation. Furthermore, the protective equipment has a sensor device for detecting a dangerous situation prior to the emergency situation of the person, when the sensor device is coupled with the securing system in such a way that upon detection of the dangerous situation of the person, the sensor device automatically sets the securing system in a securing state for protecting the person.
