Cargo Bed Drain and Wick Layout for Powertrain Fluid Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility, recreational, or off-road vehicles face issues with fluid build-up in cargo box assemblies due to spills or weather elements, which can affect the integrity and functionality of components, particularly those near the powertrain.
Innovation Solution
The cargo box assembly incorporates a drain assembly with a drain and wick system to direct fluid away from the powertrain, utilizing a seal and wick to manage fluid flow and prevent stagnation, ensuring fluid is directed to a cooler area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a cargo box assembly is used to store cargo, then cargo storage capability is improved, but fluid build-up occurs due to spills and weather elements
Solution Approach 1:
The patent extracts the fluid removal function from the cargo box by incorporating a drain assembly that channels fluid away from the cargo storage area. The drain opening and wick structure actively extract accumulated fluid from the cargo box assembly, preventing fluid build-up while maintaining full cargo storage capability.
Solution Approach 2:
The wick acts as an intermediary element between the cargo box interior and the drain opening. It mediates fluid transport by absorbing fluid from the cargo area and directing it toward the drain, enabling passive fluid removal without compromising cargo storage space.
2Device complexity
If fluid is retained within the cargo box assembly, then cargo storage is simplified, but damage to powertrain components occurs
Solution Approach 1:
The drain assembly extracts harmful fluid from the cargo box environment and redirects it away from the powertrain components. By providing a dedicated fluid egress path through the drain opening and wick structure, the system removes the harmful factor (fluid) while maintaining the simplicity of the cargo box structure.
Solution Approach 2:
The patent converts the potentially harmful presence of fluid into a beneficial drainage flow. The wick structure and drain opening work together to transform fluid that would otherwise damage powertrain components into a controlled flow that is actively directed away from sensitive areas, protecting the powertrain while maintaining structural simplicity.
3Object-affected harmful factors
If a drain assembly is added to direct fluid away from the powertrain, then protection of powertrain components is improved, but device complexity increases
Solution Approach 1:
The drain assembly is designed to be self-activating through the wick structure that automatically absorbs and directs fluid toward the drain opening without requiring external power or complex control systems. This self-service mechanism provides effective powertrain protection while adding minimal complexity to the cargo box assembly.
Solution Approach 2:
The wick structure utilizes porous material properties to enable passive fluid absorption and transport. This porous element provides an simple yet effective means of fluid management, protecting powertrain components without requiring complex mechanical or electronic systems.

Implementation Method 1
The wick may be coupled to a bottom of the tailgate and configured to direct fluid from the tailgate toward the drain
Implementation Method 2
The seal may define a seal opening configured to allow fluid to pass between the bed floor and the tailgate
Implementation Method 3
The drain may be configured to direct the fluid away from a selected portion of the utility vehicle

AI summary
A vehicle includes a plurality of ground engaging members and a frame supported by the ground engaging members. A powertrain and a utility or cargo bed are supported by the frame. The cargo bed comprises a first wall extending generally longitudinally and a second wall extending generally longitudinally, and the second wall is laterally spaced from the first wall. The cargo bed further comprises a bed floor extending between the first wall and the second wall and a tailgate. The vehicle further comprises a drain coupled to a rearward portion of the utility bed and the drain is configured to direct fluid from the bed floor to a position rearward of the bed floor and away from at least a portion of the powertrain.
