Excavator Electrical Mounting Board Layout for Tight Engine Rooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies require multiple mounting plates and housings to arrange electrical components in engine rooms, making it difficult to efficiently place components in narrower spaces, such as those found in small hydraulic excavators.
Innovation Solution
A work machine with an electrical component mounting board that allows multiple electrical components to be mounted on either the front or back side, efficiently utilizing limited space with a reduced number of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple mounting plates and housings are used to arrange electrical components, then the electrical components can be organized, but the number of parts increases and space efficiency deteriorates
Solution Approach 1:
The patent merges multiple electrical components onto a single mounting plate, eliminating the need for separate housings and multiple mounting plates. This consolidation reduces the total number of parts while maintaining organized arrangement of components such as the battery, capacitor, and relay in the engine room.
2Device complexity
If multiple mounting plates and housings are used to arrange electrical components, then the electrical components can be organized, but the device complexity increases
Solution Approach 1:
The patent combines multiple electrical components and their mounting structures into a single integrated mounting plate assembly. This reduces the number of separate parts that need to be manufactured, ordered, and assembled, thereby simplifying the manufacturing process while maintaining component organization.
3Area of stationary object
If electrical components are arranged in a narrow space, then space utilization improves, but the accessibility for maintenance deteriorates
Solution Approach 1:
The patent segments the mounting plate into multiple sections with designated areas for different electrical components (battery, capacitor, relay). This segmentation allows compact arrangement of components in limited space while maintaining individual accessibility zones for maintenance personnel to reach each component without moving others.

AI summary
A hydraulic excavator as a work machine is equipped with an engine room, and an electrical component mounting board located in the engine room, on which at least a first and second electrical components are mounted. The first electrical component is mounted on either a front or back side of the electrical component mounting board. The second electrical component is mounted on the other of the front or back side of the electrical component mounting board.
