Work Machine Power Source Isolation via Segmented Body Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machines, such as agricultural vehicles, face issues with heat, vibration, electromagnetic noise, and sound generated by the power source, which can interfere with the operation and affect the user interface.
Innovation Solution
The work machine is designed with a machine body comprising a first block and a second block disposed side by side, where the power source is placed in the first block to drive the machine body, and the user interface is located in the second block, separating the power source from the user interface to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power source is disposed in a biased manner toward one vehicle body side, then the machine body structure is simplified and easier to manufacture, but heat, vibration, electromagnetic noise, and sound from the power source interfere with the user interface operations
Solution Approach 1:
The machine body is divided into a first vehicle body and a second vehicle body, with the power source disposed in the first vehicle body and the user interface in the second vehicle body. This segmentation separates the harmful factors (heat, vibration, electromagnetic noise, sound) generated by the power source from the user interface, reducing interference while maintaining structural simplicity and ease of manufacture.
2Volume of moving object
If the power source and user interface are disposed close together, then the machine body size is reduced, but the harmful factors generated by the power source adversely affect the user interface operation
Solution Approach 1:
The machine body is segmented into two separate vehicle bodies disposed side by side. The power source is located in the first vehicle body while the user interface is located in the second vehicle body. This spatial segmentation through separate vehicle bodies reduces the adverse effects of heat, vibration, electromagnetic noise, and sound on user interface operation reliability, while the overall machine body size remains compact due to the side-by-side arrangement.
3Device complexity
If the power source is disposed in one vehicle body, then the structural complexity is reduced, but the heat, vibration, electromagnetic noise, and sound generated by the power source create a problematic environment for user interface operations
Solution Approach 1:
The machine body is divided into a first vehicle body containing the power source and a second vehicle body containing the user interface. This simple segmentation approach reduces device complexity by avoiding complex isolation structures, while simultaneously reducing environmental interference (heat, vibration, electromagnetic noise, sound) from the power source to the user interface through spatial separation.

AI summary
[Problem] A work machine in which a heat, vibration, an electromagnetic noise, sound or the like generated in a power source is unlikely to be a problem is provided. [Solution] The work machine (spraying machine 1) includes a machine body 10, a work unit, a power source 63, and a user interface 61. The machine body 10 has a first block 10L and a second block 10R disposed side by side in a left-right direction D2. The work unit is supported by the machine body 10 and performs a work. The power source 63 is disposed in the first block 10L and drives the machine body 10. The user interface 61 is disposed in the second block 10R and performs at least either one of outputting information to a user and accepting operations.
