Web Harness Leg Extensions for Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fall protection harnesses often lack adequate leg support and adjustment features, leading to discomfort and inefficiency in distributing the weight of tools and accessories, which can cause shifting and accessibility issues for users.
Innovation Solution
The development of a web harness system with leg extensions and adjustable belt configurations, incorporating multiple layers of materials such as elastomers, ballistic materials, and mesh for comfort and support, along with adjustable leg and waist components to accommodate various tool and accessory sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fall protection harnesses are used without leg support components, then the harness structure remains simple, but weight distribution is inadequate and comfort is reduced
Solution Approach 1:
The harness is divided into distinct functional modules: waist belt, leg support components with extensions, and tool pouches. Each module independently performs its function, allowing the leg support components to be added without redesigning the entire harness structure.
Solution Approach 2:
The leg support components serve multiple functions: providing structural support, distributing weight, enabling adjustment for different body sizes, and offering attachment points for tools. This multi-functionality improves comfort without requiring separate dedicated components for each purpose.
2Adaptability or versatility
If fixed belt configurations are used, then the harness structure remains simple, but adaptability to various tool and accessory sizes is poor
Solution Approach 1:
The belt configuration includes adjustable elements that allow users to modify the harness fit and tool pouch positioning based on their body measurements and tool sizes. This dynamic adjustability enables the same harness structure to adapt to various configurations without requiring multiple specialized harnesses.
3Stress or pressure
If leg support components are added to distribute weight, then weight distribution improves, but the harness structure becomes more complex
Solution Approach 1:
The weight distribution function is isolated to specific leg support components rather than requiring redistribution throughout the entire harness. These components include extensions and adjustment mechanisms that locally manage weight bearing on the legs, minimizing the complexity increase to only the necessary areas.
4Ease of operation
If multiple layers of materials are incorporated for comfort, then comfort and support improve, but manufacturing complexity increases
Solution Approach 1:
The harness utilizes composite material construction with multiple layers including foam padding, fabric, and structural elements. These layers are manufactured separately and then assembled through standard attachment methods, allowing each material to be optimized for its specific function while keeping the overall manufacturing process manageable through modular assembly.
