Fall Arrest Harness with Integrated Storage Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall arrest harnesses require multiple accessories, are not protected from dirt when not in use, and tend to get tangled, making them cumbersome and difficult to deploy for subsequent use.
Innovation Solution
A fall arrest harness design incorporating a semi-rigid plate that forms part of a storage bag, integrating all components such as chest and thigh straps, connecting members, and the lanyard, eliminating the need for separate accessories and providing a self-contained, easy-to-deploy system with a non-removable attachment lanyard and energy absorber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate accessories are used to constitute the harness, then the harness can be assembled with standard components, but the device complexity increases and assembly becomes cumbersome
Solution Approach 1:
The patent combines multiple separate harness components (straps, connecting members, attachment lanyard, storage bag) into a single integrated dorsal connection zone structure. The semi-rigid plate serves as a common mounting surface for all components, eliminating the need for multiple separate accessories and simplifying the overall device while maintaining functionality.
2Ease of operation
If the harness is stored without protection, then it is easily accessible, but it gets dirty and the straps become tangled
Solution Approach 1:
The storage bag is integrated into the dorsal connection zone structure itself, forming a self-contained unit. When the harness is not in use, all straps and components are stored within this integrated bag, protecting them from dirt and preventing tangling, while the entire unit remains easily transportable and accessible.
Solution Approach 2:
The straps and connecting members are nested within the storage bag when not in use. The semi-rigid plate forms the bottom of the bag, creating a nested configuration where flexible components are contained within a protective outer structure, preventing contamination and tangling.
3Adaptability or versatility
If the attachment lanyard is removable, then it can be adjusted or removed when not needed, but it increases the number of parts and assembly complexity
Solution Approach 1:
The attachment lanyard is permanently integrated into the dorsal connection zone structure, eliminating the need for separate carabiners or detachable connectors. The lanyard is sewn directly to the semi-rigid plate, reducing the number of parts while maintaining the ability to attach and detach the lanyard as needed through its fixed attachment point.

AI summary
The harness (1) has an upper part formed of front and rear thoracic straps (2, 3), extending towards a lower part for forming thigh boot straps (4, 5). The straps (2-5) are connected with each other in a dorsal connection zone formed of semi-rigid connection plate (6) and at their free ends to the straps (4, 5) by connection members (8-11). The plate forms a bottom of a storage bag (12) incorporating components e.g. straps, members, of the harness in a permanent operational manner, where the bag is made of synthetic fluorescent material. An attachment loin (7) and the bag integrate the plate.
