Riding Work Machine Electric Component Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In riding work machines with engines housed in hoods, accessing electric components for maintenance is inconvenient due to their placement, and they are susceptible to water splashing from wheels.
Innovation Solution
Electric components are positioned under the deck panel, with a shielding member between the wheels and components to prevent water splashing, allowing for easy maintenance without opening the hood and utilizing dead space effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric components are disposed inside the hood, then the space upwardly of the hood can be utilized for mounting devices such as a grass collector, but it becomes inconvenient to access the electric components for maintenance without opening the hood
Solution Approach 1:
The patent divides the installation space into two separate locations: the hood area for the engine and optional devices, and the deck panel area for electric components. This segmentation allows independent access to each zone, enabling maintenance of electric components without opening the hood while preserving the ability to mount devices on the hood.
Solution Approach 2:
The electric components are extracted from the hood and relocated to the deck panel area. This extraction eliminates the need to open the hood for maintenance access while maintaining the hood's availability for optional device mounting.
2Ease of operation
If electric components are disposed under the deck panel, then accessibility for maintenance is improved without opening the hood, but the components become vulnerable to water splashing from the wheels
Solution Approach 1:
The patent introduces a shielding member as an intermediary barrier between the wheels and the electric components. This shielding member blocks water splashed from the wheels from reaching the electric components, while still allowing the components to be accessed for maintenance through openings in the shielding member or through the deck panel.
3Ease of repair
If the hood is opened for maintenance of electric components, then the components can be accessed, but the hood and engine area are exposed to external elements and require reassembly
Solution Approach 1:
The electric components are extracted from the hood and placed in the deck panel area, eliminating the need to open the hood for maintenance. This extraction removes the time-consuming steps of opening and closing the hood while maintaining full access to the components.
Solution Approach 2:
The patent segments the maintenance access path by providing direct access points in the deck panel area, separating the maintenance function from the hood operation. This allows components to be serviced independently without affecting the hood assembly.

AI summary
In a riding work machine, various electric components are disposed under a deck panel 40 at a laterally outer portion of a vehicle body frame 10 and within a spacing between front wheels IF and rear wheels 1R in a front/rear direction. And, between the front wheels IF or the rear wheels 1R and the electric components, there is provided a shielding member 6 configured to suppress falling of scattering water splashed from the front wheels IF or the rear wheels 1R.
