Loader Mast Hydraulic Hose Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing loader work machines face issues with hydraulic hoses extending on the inner or outer sides of the mast, which impairs commercial value, obstructs the driver's view, and increases vehicle width, while also risking damage from obstacles.
Innovation Solution
The hydraulic hoses are routed vertically within the mast, with one end connected to the control valve at the lower portion and the other at the upper portion, ensuring they do not extend on the outer side and are protected from damage, improving visibility and reducing the risk of collision.

Engineering Contradiction Analysis
1Illumination intensity
If the hydraulic hose is exposed on the inner side of the mast, then the driver's view to the front side is obstructed and the commercial value is impaired, but the hose routing path is simplified
Solution Approach 1:
The hydraulic hose is nested within the mast structure, routing through the hollow interior space of the mast rather than being exposed on the exterior. This conceals the hose within the existing structural component, eliminating visual obstruction while managing the hose through the mast's internal cavity
Solution Approach 2:
The mast serves as an intermediary structure that mediates between the control valve and the hydraulic actuator. The hose passes through the mast's interior, using the mast as a protective conduit and routing channel that simultaneously hides the hose and provides structural protection
2Object-affected harmful factors
If the hydraulic hose is exposed on the outer side of the mast, then the vehicle width increases and the hose is vulnerable to damage from obstacles, but the hose routing is simplified
Solution Approach 1:
The hydraulic hose is nested within the mast structure, routing through the hollow interior space of the mast rather than being exposed on the exterior. This conceals the hose within the existing structural component, eliminating visual obstruction while managing the hose through the mast's internal cavity
Solution Approach 2:
The mast serves as an intermediary structure that mediates between the control valve and the hydraulic actuator. The hose passes through the mast's interior, using the mast as a protective conduit and routing channel that simultaneously hides the hose and provides structural protection
3Reliability
If the hydraulic hose is routed through the inside of the mast, then the driver's view is maintained and the hose is protected from damage, but the hose routing path becomes more complex
Solution Approach 1:
The mast structure serves multiple functions: it provides structural support for the loader, acts as a protective enclosure, and serves as a routing conduit for the hydraulic hose. By making the mast multi-functional, the hose routing complexity is absorbed into the existing structural design rather than requiring separate protective measures
Solution Approach 2:
The mast's hollow interior space, which is already part of its structural design, is utilized to route and protect the hydraulic hose. The structure serves itself by providing its own internal volume for conduit purposes, eliminating the need for separate protective casings or external routing
4Shape
If the hydraulic hose is routed through the inside of the mast, then the appearance of the loader is improved, but the hose routing path becomes more complex
