Sub-Pelvic Web Harness Layout for Adjustable Leg Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection harnesses often fail to provide adequate leg support and comfort, leading to mobility issues and discomfort for users in elevated environments.
Innovation Solution
A web harness system with leg extensions and adjustable leg support components, including a sub-pelvic support portion and leg harness portions with adjustable belts, providing enhanced fit and comfort through multiple adjustment positions and materials like webbing polyester and aluminum alloy buckles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional harness designs are used, then the structure is simple, but leg support and comfort are inadequate
Solution Approach 1:
The harness is divided into distinct functional segments including upper webbing portion, lower webbing portion, sub-pelvic support portion, and leg harness portions with separate leg extensions for each leg. This segmentation allows each component to be optimized independently for its specific function while maintaining overall system simplicity.
Solution Approach 2:
The leg harness portions include adjustable belts with multiple adjustment positions that allow the harness to adapt dynamically to different user leg circumferences and preferences. This dynamic adjustability enhances comfort and support without requiring a completely complex structured design.
2Adaptability or versatility
If adjustable leg support components are added, then fit and comfort are improved, but device complexity increases
Solution Approach 1:
The adjustable belts serve multiple functions: they provide leg support, allow size adjustment, and ensure proper positioning of the leg extensions. This multi-functionality reduces the need for additional separate components, maintaining relative simplicity while improving adaptability.
Solution Approach 2:
Adjustment mechanisms are provided specifically at the leg harness portions where localized fit adjustment is most needed, rather than throughout the entire harness. This targeted approach improves comfort where required without unnecessarily increasing overall device complexity.

AI summary
A web harness system includes an upper webbing portion. A lower webbing portion is connected to the upper webbing portion. A sub-pelvic support portion is connected to the lower webbing portion. The sub-pelvic support portion is configured as a strap for placement under a user buttocks. A leg harness portion is connected to the sub-pelvic support portion. The leg harness portion includes: a first leg extension connected to a first portion of the sub-pelvic support portion and disposed at a position that aligns with a first side of a user hip; a second leg extension is connected to a second portion of the sub-pelvic support portion and disposed at a position that aligns with a second side of a user hip; a right leg adjustment belt is connected to the first leg extension; and a left leg adjustment belt is connected to the second leg extension.
