Working Machine Mounting Plate Layout for Hydraulic Hose Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation structures for working machines, such as compact excavators, fail to efficiently arrange both electric components and hydraulic hoses in limited mounting spaces without interference, particularly for small machines with restricted space.
Innovation Solution
A plate is fixed to the machine body structure with supports, allowing the hydraulic hose to be arranged between these supports and the electric component to be mounted adjacent to the hose, with a guide member to regulate hose movement and prevent damage, enabling efficient coexistence and optimal use of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If electric components and hydraulic hoses are installed in limited mounting space of small working machines, then space utilization is improved, but interference between components and hoses occurs
Solution Approach 1:
The plate surface is segmented into distinct functional zones: a hydraulic hose arrangement section and an electric component mounting section. This spatial segmentation allows hydraulic hoses and electric components to be installed in separate designated areas, preventing interference while efficiently utilizing the limited mounting space of small working machines.
Solution Approach 2:
Different regions of the plate are assigned different functional qualities: one region is optimized for hydraulic hose arrangement with appropriate routing paths, while another region is designated for electric component mounting with suitable mounting surfaces. This local differentiation enables each component type to be installed in its optimal location without interfering with the other.
2Area of stationary object
If hydraulic hose is arranged vertically in small working machines, then space efficiency is improved, but existing fixture structures cannot accommodate this arrangement
Solution Approach 1:
The plate structure serves multiple functions: it provides a mounting surface for electric components, creates designated arrangement sections for hydraulic hoses, and enables both vertical and horizontal installation configurations. This multi-functionality allows the same basic structure to accommodate vertical hydraulic hose arrangement in small machines while maintaining compatibility with various installation scenarios.
3Area of stationary object
If electric component and hydraulic hose are disposed closely to maximize space, then mounting space efficiency is improved, but damage risk to hydraulic hose increases
Solution Approach 1:
The plate is divided into separate arrangement sections for hydraulic hoses and electric components. This segmentation creates natural spatial separation that reduces the risk of damage to hydraulic hoses from heat generated by electric components, while still allowing both to be installed in the same limited mounting area with improved space efficiency.

AI summary
The present invention is provided with: a plate provided while one surface is directed toward the machine body structure of a working machine; a first support and a second support, which are raised from the one surface of the plate and which affix the plate to the machine body structure; a hydraulic hose which is routed on and along the one surface of the plate; and an electric component mounted on the one surface of the plate. The one surface of the plate has a hydraulic hose arrangement section where the hydraulic hose is arranged between the first support and the second support, and an electric component mounting section where the electric component is mounted so as to be adjacent to the hydraulic hose arrangement section.
