Adjustable Harness Chest Plate for Tool Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing harnesses for heavy equipment, such as clearing saws, are not adequately adjustable for both men and women, leading to discomfort due to poor weight distribution and pressure on the breasts, especially during prolonged use.
Innovation Solution
A harness with a chest plate that includes a fastening device with a flat, hook-like shape and a slidable attachment for the side strap, allowing for adjustable positioning to distribute weight more evenly across the body, reducing pressure on the breasts and improving comfort for both genders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chest plate is positioned directly over the breasts, then the side strap can be properly positioned for weight distribution, but this causes pressure and discomfort on the breasts during prolonged use
Solution Approach 1:
The chest plate is made adjustable in position along the support strap, allowing it to be moved up or down according to the user's body type and comfort needs. This dynamic adjustment enables women to reposition the chest plate away from breast pressure areas while maintaining proper side strap positioning for weight distribution.
Solution Approach 2:
The invention changes the positional parameter of the chest plate along the support strap, allowing it to be adjusted to different heights. This parameter change enables the chest plate to be positioned optimally for both men and women, avoiding breast pressure for women while maintaining proper weight distribution geometry.
2Ease of operation
If the chest plate is raised to a higher position on existing harnesses, then breast pressure is reduced, but the side strap becomes positioned too high in the armpit which is uncomfortable or makes use of the harness impossible
Solution Approach 1:
The fastening device is designed with slidable components that allow the side strap attachment point to be moved up and down the support strap. This dynamic positioning capability enables the side strap to be adjusted to optimal positions for different users while maintaining chest plate height adjustments.
Solution Approach 2:
The chest plate is divided into separable parts with independent adjustment mechanisms. The fastening device can be detached and reattached at different positions along the support strap, allowing independent adjustment of the side strap position relative to the chest plate position.
3Ease of operation
If the chest plate is lowered to a place below the breasts, then breast pressure is avoided, but the side band is positioned too low and will not fulfill its weight distributing object, and the shoulder straps will be too long so that the harness will be rendered unstable
Solution Approach 1:
The adjustable fastening device allows the side strap attachment point to be dynamically repositioned along the support strap. This enables the side strap to be lowered for women's comfort while maintaining proper tension and positioning for weight distribution, and allows shoulder strap length adjustment to maintain harness stability.
Solution Approach 2:
The invention changes multiple parameters simultaneously - the chest plate position, side strap position, and shoulder strap length - to achieve optimal comfort and stability. The support strap length can be adjusted to compensate for lower chest plate positioning while maintaining proper geometry for weight distribution and shoulder strap tension.
4Adaptability or versatility
If a single harness is designed for men, then it provides proper weight distribution for men, but it causes discomfort and pressure on women's breasts during prolonged use
Solution Approach 1:
The harness is designed with universal adjustability features that allow it to be properly fitted for both men and women. The chest plate, side straps, and support straps can all be adjusted to optimal positions for different body types, making a single harness design suitable for use by both genders without requiring separate men's and women's models.
Solution Approach 2:
The adjustable fastening device enables the harness to adapt its configuration dynamically to different users. Women can adjust the chest plate position downward and side strap position to avoid breast pressure, while men can position components for optimal weight distribution, allowing one harness design to serve both genders comfortably.

AI summary
The invention relates to a harness for carrying a handheld motor-driven tool, such as a clearing saw. The harness comprises a back portion, two shoulder straps (2) a support strap (6) for the tool, a side strap (4) for distributing the weight of the tool, and a chest plate (1). A fastening device (10) for the side strap (4) is detachable from the chest plate (1) and is attachable on the support strap (6) below the chest plate (1).
