Two-Piece Fall Protection Belt Fitting for Replaceable Webbing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal fall protection belts are complex to manufacture and difficult to maintain, with elements that are inseparable and require permanent connections, making replacement of components challenging.
Innovation Solution
A two-piece fitting part design with a body that can be connected to belt sub-elements, featuring openable webbing and bridge holes, secured by screws through transverse holes, allowing for semi-permanent connections and easy assembly or replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If webbings are permanently connected to the fitting part by passing through webbing openings and sewing loops, then the connection is secure and reliable, but the belt becomes difficult to maintain and components cannot be replaced
Solution Approach 1:
The fitting part is divided into two separate parts (first part and second part) that can be disconnected from each other. The webbing is connected to the first part while the second part can be removed independently, allowing maintenance and replacement of components without affecting the entire assembly. This segmentation enables the webbing to remain permanently secured to the first part while the second part can be easily replaced.
2Strength
If the fitting part is designed as a single rigid body with webbing openings, then the structure is simple and strong, but it is complex to manufacture and difficult to maintain
Solution Approach 1:
The fitting part is segmented into two separate parts that can be manufactured independently and then assembled together. This reduces manufacturing complexity as each part can be produced separately using standard processes, and the webbing connections can be established on the first part before final assembly with the second part.
Solution Approach 2:
The webbing loops are pre-formed and permanently connected to the first part before the second part is attached. This preliminary action allows the webbing connections to be established and secured in advance, simplifying the overall assembly process and reducing manufacturing complexity.
3Ease of operation
If all belt elements are released when the bolt is removed from shackle-type fitting parts, then the fitting part is easy to disassemble, but there are no dedicated webbing openings and all webbings rub against each other
Solution Approach 1:
The fitting part is segmented into two parts where the webbing is permanently connected to the first part. The second part can be removed independently without releasing the webbing, eliminating the harmful effect of all webbings rubbing against each other during disassembly. The webbing remains secured in its dedicated opening on the first part.
4Adaptability or versatility
If the body is passed through by two webbing openings in the usual way, then the fitting part can connect belt sub-elements, but it is complex to manufacture and difficult to maintain
Solution Approach 1:
The fitting part is divided into two separate parts, with the webbing connection features integrated into the first part. This segmentation allows the webbing to be permanently and securely connected to the first part during manufacturing, while the second part can be independently assembled or replaced, reducing overall assembly complexity and improving maintainability.

AI summary
The disclosure relates to a belt and includes a fitting part and at least a first and a second belt sub-element enclosing a body part, the fitting part including a body that is designed to be connected to the first belt sub-element, to the second belt sub-element and to a flexible bridge, with the body of the fitting part including a first part and a second part which can be brought into an assembled state and into a separated state, with the first part and/or the second part including at least one first external groove for the first belt sub-element. In the assembled state, the first groove is completed by the respective other part to form the first webbing opening passing through the body in order to connect therein a first webbing of the first belt sub-element enclosing a body part to the fitting part in a semi-permanent way.
