Integrated Harness Safety Garment for Drag Rescue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety garments are unsafe for rescuing individuals in hazardous oil and gas industry environments, as they often tear when attempting to drag a victim, posing risks to both the rescuer and the victim, and lack effective mechanisms for secure and efficient extraction from dangerous situations.
Innovation Solution
A wearable safety garment system with an integrated harness system, featuring a shoulder harness, front torso harness, and groin harness, connected to handles on the garment's interior side, allowing for secure and controlled dragging without tearing, and including removable patches to conceal the handles and prevent snagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a typical work uniform garment is used without an integrated harness system, then the garment maintains a simple and typical appearance, but it tears when attempting to drag a victim from hazardous environments
Solution Approach 1:
The patent combines the work uniform garment with an integrated harness system into a single composite structure. The harness straps are incorporated as part of the garment itself, with straps extending from the shoulders through the torso to the legs, creating a unified rescue-ready garment that maintains typical work uniform appearance while providing the strength needed for victim extraction.
2Reliability
If a harness system is integrated into the garment, then the garment can securely drag a victim without tearing, but the garment structure becomes more complex
Solution Approach 1:
The harness system is segmented into distinct functional zones: shoulder straps for upper body support, torso straps for midsection stability, and leg straps for lower body anchoring. Each segment is independently positioned and anchored to specific garment locations, allowing the complex harness function to be divided into manageable, coordinated components that work together reliably.
Solution Approach 2:
The integrated harness garment serves multiple functions simultaneously: it provides the structural strength for victim extraction, maintains the appearance of a typical work uniform, and can be worn as regular protective clothing. The same garment structure that protects workers during normal operations also provides the harness functionality needed for emergency rescue without requiring separate equipment.
3Ease of operation
If handles are exposed on the garment for rescuer access, then rescuers can easily grasp and pull the victim, but the handles may snag on surrounding objects
Solution Approach 1:
The patches are pre-positioned over the handles in their normal worn state, concealing them from potential snagging objects. The patches are designed to be easily removable by rescuers when needed, providing preliminary protection against snagging while maintaining ease of access when required. This preliminary concealment action prevents harmful snagging before it can occur.

AI summary
A safety garment system including a garment having an interior side, an exterior side, a harness, a first handle, and a second handle. The harness is configured on the interior side of the garment. The first handle and the second handle are configured on the exterior side and are positioned on opposing sides at a shoulder portion of the garment. The garment can be used to safely drag a wearer to safety in an emergency using the harness, the first handle, and the second handle.
