Multi-Opening D-Ring for Lineman Safety Belt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing D-rings on body belts for linemen are overcrowded, increasing the risk of accidentally detaching the wrong safety device and complicating the connection process, which can lead to safety hazards during elevated work tasks.
Innovation Solution
A D-ring with multiple separate openings allows for safe and distinct connection of devices, maintaining a compact design while reducing weight and size, by incorporating two or more openings with different geometries, such as D-shaped or circular, to accommodate various tools and a belt receiving aperture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple safety devices are attached to traditional single-opening D-rings, then the lineman can secure multiple devices, but the D-ring becomes crowded increasing the risk of accidentally detaching the wrong device
Solution Approach 1:
The D-ring is divided into multiple separate openings (first opening and second opening) instead of using a single opening. Each opening can independently receive and secure different safety devices, allowing the devices to be spatially separated. This segmentation prevents devices from crowding each other and reduces the risk of accidentally detaching the wrong device, while still enabling multiple devices to be connected to the same D-ring.
2Adaptability or versatility
If multiple safety devices are attached to traditional D-rings, then more safety equipment can be secured, but the connection process becomes more complex and time-consuming
Solution Approach 1:
By providing multiple separate openings, each opening can be independently used to connect different safety devices. This segmentation simplifies the connection process compared to trying to fit multiple devices into a single crowded opening, as each device can be attached to its designated opening without interference from other devices.
3Adaptability or versatility
If traditional D-rings are used with multiple devices, then all necessary safety equipment can be attached, but the overall size and weight of the body belt increases
Solution Approach 1:
Multiple openings are integrated into a single D-ring structure, allowing multiple safety devices to be connected through one D-ring component rather than requiring separate D-rings for each device. This merging approach reduces the total number of separate components needed, thereby reducing the overall weight and size of the body belt while maintaining the capacity to attach multiple safety devices.

AI summary
A D-ring, comprising a body having a first surface and a second surface and a plurality of apertures formed through first and second surfaces. The D-ring comprises two or more separate rated apertures for receiving a device or a connector to a device. A first aperture is formed through the first and second surfaces and positioned on the distal portion of the body. A second aperture is formed through the first and second surfaces such that the second aperture is adjacent to the first aperture. Additionally, there is a belt receiving aperture formed through said first and second surfaces positioned on the proximal portion of the body.
