Utility Vehicle Battery Positioning for Waterproofing and Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility vehicles with batteries placed below the seat face accessibility issues during maintenance and require waterproofing to prevent water ingress, especially when driving over rivers.
Innovation Solution
The battery is positioned above the seating surface, behind a back panel, with a carrier and upper cover providing waterproofing and easy access, while the power unit and exhaust pipe are configured to minimize heat transfer and water exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery is disposed below the seat, then the battery can be installed in a compact space, but the battery becomes difficult to access during maintenance and requires additional waterproofing measures
Solution Approach 1:
The battery position is moved from the horizontal plane (below the seat) to a different spatial arrangement (behind the back panel), utilizing the depth dimension of the vehicle interior. This dimensional shift allows the battery to be accessible from the rear while maintaining compact installation space within the vehicle body.
2Volume of moving object
If the battery is disposed below the seat, then the battery can be installed in a compact space, but additional waterproofing measures are required to prevent water ingress
Solution Approach 1:
By relocating the battery to a position behind the back panel, the design utilizes the vehicle's structural depth to create a naturally protected space. This positional change leverages the existing vehicle body structure as a waterproof barrier, eliminating the need for separate waterproofing components.
3Reliability
If the battery is disposed behind the back panel and above the seating surface, then waterproofing is improved and accessibility is enhanced, but the battery occupies space in the upper rear region
Solution Approach 1:
The battery is positioned in a specific localized region (behind the back panel and above the seating surface) where it can be easily accessed and is naturally protected from water. This localized placement optimizes both accessibility and waterproofing without requiring the entire upper rear region to be dedicated to battery housing.
