Motor Vehicle Battery Tray Overlapping Flange Liquid Diversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle designs are prone to functional failures when water or liquids enter the space above the floor panel where the battery pack is mounted, leading to potential damage and malfunction.
Innovation Solution
The implementation of waterproof trays and drain plugs on the floor panel, along with a specific arrangement of flange portions and recessed areas, ensures that liquids are diverted away from the battery pack and cooling device, preventing water from accumulating and causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery pack is mounted directly on the floor panel, then the space utilization is improved, but liquid may enter the battery pack causing functional failure
Solution Approach 1:
The floor space is segmented into multiple recessed portions, with each recessed portion containing a tray that holds either the battery pack or battery pack-associated components. This segmentation prevents liquid from spreading between components while maintaining efficient space utilization.
Solution Approach 2:
Trays are introduced as intermediary structures between the floor panel and the battery pack/components. These trays act as barriers that prevent liquid from reaching the electrical components while allowing the components to be mounted in the recessed portions of the floor panel.
2Reliability
If flange portions are made to overlap vertically, then liquid flow path is blocked, but structural complexity increases
Solution Approach 1:
The flange portions extend in the vertical direction from the trays, creating a three-dimensional overlapping structure. This vertical arrangement effectively blocks liquid flow paths between recessed portions while maintaining a relatively simple horizontal tray structure.

AI summary
A motor vehicle includes a floor panel, a battery pack, a battery pack-associated component, a first tray, a first flange portion, a second tray, and a second flange portion. The battery pack is arranged on the first tray. The first tray is arranged on the floor panel of the motor vehicle. The first flange portion is provided on a first peripheral edge. The first peripheral edge is a peripheral edge of the first tray. The battery pack-associated component is arranged on the second tray. The second tray is arranged on the floor panel of the motor vehicle. The second flange portion is provided on a second peripheral edge. The second peripheral edge is a peripheral edge of the second tray. The second flange portion is located above the first flange portion in a vertical direction of the motor vehicle. The second flange portion overlaps with the first flange portion in the vertical direction of the motor vehicle. The first flange portion projects toward the second tray side. The second flange portion projects toward the first tray side.
