Safety Harness Coupler Layout for Tangle-Free Belt Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Safety belts and harnesses tend to become tangled and difficult to access, leading to user frustration and potential safety hazards, as well as damage to vehicle interiors due to unsecured belts bouncing against internal components.
Innovation Solution
A separating and fastening system comprising couplers with arms and plates that securely attach to vehicle structures, allowing safety belts and harnesses to be easily accessed and maintained in an untangled configuration, using fasteners and adhesive layers for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety belts and harnesses are provided with numerous straps and buckles to provide comprehensive protection, then the safety coverage is improved, but the belts and harnesses tend to twist, turn, and become tangled
Solution Approach 1:
The harness is divided into separate functional components: a wearable harness portion with buckles and a separate coiling/coupling mechanism. This segmentation allows the protective straps to be kept organized in a designated coiled position while maintaining all necessary safety features, resolving the contradiction between comprehensive protection and ease of access.
Solution Approach 2:
A coupler mechanism acts as an intermediary between the harness and the vehicle anchor point. This coupler provides a designated receiving position that guides and maintains the harness in an organized, coiled state, preventing tangling while preserving the integrity and coverage of the safety system.
2Ease of operation
If safety belts and harnesses are left unsecured when not in use, then ease of access is improved, but they bounce repeatedly against plastic or metal within the interior of the vehicle causing damage
Solution Approach 1:
The harness is extracted from its operational position and placed into a dedicated coiled receiving position within the coupler when not in use. This separation removes the harness from the vehicle interior environment, preventing it from bouncing against and damaging plastic or metal surfaces while maintaining quick accessibility when needed.
Solution Approach 2:
The coupler is pre-configured with a designated coiling position that automatically guides and secures the harness in an organized state before use. This preliminary arrangement prevents the harness from becoming loose and damaging the vehicle interior, while still allowing rapid deployment when required.
3Object-generated harmful factors
If safety belts and harnesses are secured in a fixed position, then damage to vehicle interior is prevented, but the belts and harnesses become difficult to access and may become tangled
Solution Approach 1:
The coupler mechanism is designed to be dynamic, allowing the harness to transition between a secured coiled position and an operational deployed position. The coupler maintains the harness in an organized state during storage but enables quick, easy access when needed, resolving the contradiction between damage prevention and accessibility.
Solution Approach 2:
The harness is nested within the coupler structure in a designated coiling position, similar to a nested doll configuration. This nesting keeps the harness organized and prevents damage to the vehicle interior while allowing the user to easily extract and deploy the harness when needed, maintaining both protection and accessibility.

AI summary
A system includes a coupler with a first arm and a second arm. The first and second arms configured to couple to a roll cage. A first end may include a first recessed portion and a first aperture. A third end may include a second recessed portion and a second aperture. The first and third ends may contact each other and be secured together via a first fastener that passes through the first aperture and the second aperture. Further, the first recessed portion and the second recessed portion may receive a second fastener therebetween that may receive a latch plate of a safety belt or safety harness to maintain it in an upward position.
