Solution Overview

Problem

Existing fender structures for work machines lack the ability to easily adjust the angular position of the fender arch relative to the wheel without altering the support arm's position, limiting flexibility and compatibility with different-sized support arms.

Innovation Solution

Incorporating an adjustable fender arch support with a frame part and an adjustment part that allows for adjustable angular positioning of the fender arch, enabling selection of the correct angular position without altering the support arm's position, and allowing for the use of different-sized support arms with the same frame part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the fender arch position is adjusted by altering the support arm position, then the angular position of the fender arch can be changed, but the support arm repositioning is complex and time-consuming

Engineering Contradiction:
Improveangular position adjustment of fender archVSAvoidsupport arm repositioning complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The arch support is divided into two separate parts: a frame part that remains fixed to the support arm, and an adjustment part that can be independently positioned relative to the frame part. This segmentation allows the fender arch angular position to be adjusted by moving only the adjustment part, while the support arm remains in its original position, thereby reducing repositioning complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustment mechanism introduces a new degree of freedom by allowing relative movement between the frame part and adjustment part in a dimension perpendicular to the support arm's mounting direction. This enables angular positioning of the fender arch without requiring repositioning of the support arm itself, solving the contradiction between adjustability and repositioning complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a fixed arch support design is used, then the structure is simple, but it cannot accommodate different-sized support arms or adjust fender arch positioning

Engineering Contradiction:
Improvecompatibility with different support armsVSAvoidarch support structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame part is designed with a universal interface that can accommodate multiple sizes and types of support arms. The adjustment part can be positioned at various locations on the frame part, allowing the same arch support assembly to work with different support arm configurations. This multi-functionality achieves adaptability without significantly increasing overall structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An arch support (3) for a work machine fender arch (2), the arch support intended to be fastened to the fender arch (2) on its downward facing side to support the fender arch (2) to retain its shape. The arch support (3) comprises a frame part (8), an adjustment aperture (15) in the frame part (8) and an adjustment part (6) arrangeable into the adjustment aperture (15) in the frame part (8). The relative position of the arch support (3) frame part (8) and the adjustment part (6) is adjustable by rotating the frame part (8) and the adjustment part (6) relative to each other to adjust a position of the fender arch (2) to be fastened to the arch support (3).
