Adjustable Roping Harness with Movable Comfort Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roping harnesses are difficult to manage in settings where users of varying builds are served, as they require a large inventory of non-adjustable or slightly adjustable harnesses, leading to discomfort due to inadequate fit and limited adjustability, especially in the pelvic region.
Innovation Solution
An adjustable roping harness with a belt equipped with movable comfort pads and adjustable thigh straps, featuring blocking stops to prevent excessive movement and ensure maximum coverage by foam pads, allowing for easy adjustment to fit a range of pelvis sizes from 60 cm to 100 cm and beyond, while maintaining user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single adjustable harness is used to fit different pelvis sizes (60cm to 100cm), then the quantity of harnesses to manage is reduced, but the comfort and coverage are insufficient for users at the extremes of the size range
Solution Approach 1:
The belt is divided into multiple segments: a fixed central portion with the lumbar foam pad and adjustable side portions with additional foam pads. This segmentation allows the fixed central portion to maintain consistent coverage for all users while the adjustable side portions adapt to different pelvis circumferences, ensuring both comfort and adaptability across the full size range.
Solution Approach 2:
The harness incorporates an adjustment mechanism that allows the belt circumference to be dynamically changed. The side portions of the belt can be extended or retracted to accommodate different pelvis sizes, transforming a static design into a dynamic one that adapts to each user's specific measurements while maintaining proper foam pad coverage.
2Adaptability or versatility
If the belt is made fully adjustable to accommodate all sizes, then versatility is improved, but the structural complexity and difficulty of adjustment increase
Solution Approach 1:
The adjustment mechanism serves multiple functions: it adjusts the overall belt circumference to fit different pelvis sizes and simultaneously positions the foam pads correctly along the belt. This multi-functionality reduces the need for separate adjustment systems while maintaining simplicity and effectiveness across the full size range.
Solution Approach 2:
The foam pads are pre-positioned on the belt at optimal locations for maximum comfort and coverage. This preliminary positioning ensures that when the belt is adjusted to different sizes, the foam pads maintain their beneficial placement without requiring complex repositioning mechanisms, thereby simplifying the overall adjustment system.

AI summary
The roping harness comprises:a belt provided with a first strap and with at least first and second comfort parts arranged between the first strap and the user,a pair of thigh straps,a connecting element connected to the pair of thigh straps,a first adjustment device configured to adjust the length of the first strap and to define the circumference of the belt.The first comfort pad and second comfort pad are fitted movable in translation with respect to one another. The first comfort pad is fitted movable in translation with respect to the first strap along the first strap. The belt comprises at least a first blocking stop configured to prevent movement of the first comfort pad with respect to the second comfort pad beyond a threshold value, the first adjustment device forming a second blocking stop of the first comfort pad.
