Working Machine Pad Support Structure With Independent Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing working machine support belt technology, such as JP H10 98 930 A, lacks effective mechanisms for adjusting the position of the working machine pad to accommodate varying user physiques and machine sizes.
Innovation Solution
The working machine support belt incorporates front and rear length adjusting mechanisms in its support bands, allowing for independent adjustment of the working machine pad's position in both the front-rear and left-right directions, and around the waist, via interconnected waist and side belts with locking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one length adjusting mechanism is provided between the front end portion of the working machine pad and the side belt, then the position of the working machine pad can be adjusted, but the adjustability is insufficient to accommodate varying user physiques and machine sizes
Solution Approach 1:
The support belt is divided into multiple independent adjustable segments: a first length adjusting mechanism in the waist belt, a second length adjusting mechanism in the front support band, and a third length adjusting mechanism in the rear support band. This segmentation allows independent adjustment of each segment to achieve comprehensive positioning adaptability for different user physiques and machine sizes.
Solution Approach 2:
The patent implements dynamic adjustability by providing multiple length adjusting mechanisms that can be independently modified during operation. The working machine pad position can be dynamically adjusted in both the front-rear direction (via front and rear support bands) and the left-right direction (via waist belt), transforming a static single-position system into a dynamic multi-position system.
2Adaptability or versatility
If multiple length adjusting mechanisms are provided in the front and rear support bands, then the position of the working machine pad can be freely adjusted in the front-rear and left-right directions, but the device complexity increases
Solution Approach 1:
Each length adjusting mechanism is designed as a universal component that performs multiple functions: the first length adjusting mechanism in the waist belt adjusts both the overall belt circumference and influences pad positioning, while the second and third mechanisms in the front and rear support bands respectively control the pad's position in the front-rear direction. This multi-functionality reduces the need for additional specialized components.
Solution Approach 2:
The patent combines the adjustment functions into an integrated system where the waist belt, front support band, and rear support band work together through their respective length adjusting mechanisms. The locking portions connect these components, merging them into a cohesive adjustable structure that achieves comprehensive pad positioning with a coordinated set of mechanisms rather than separate independent systems.
