Vehicle Floor Assembly with Waterproof Drainage Basket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively prevent soiling and damage to vehicle luggage compartments when storing wet and/or dirty objects, such as shoes, as they often come into contact with other parts of the compartment, leading to potential damage and cleanliness issues.
Innovation Solution
A floor assembly featuring a basket within a waterproof tray-like recess covered by a lid, allowing wet and/or dirty objects to be stored without direct contact with the compartment, with features like inclined bottom walls and drain holes for efficient drainage and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wet and/or dirty objects are stored directly in the luggage compartment, then storage convenience is improved, but the compartment becomes soiled and damaged
Solution Approach 1:
A waterproof tray with lid is introduced as an intermediary container between the wet/dirty objects and the luggage compartment. The tray completely encloses the objects, preventing direct contact with the compartment interior, while still allowing the objects to be stored conveniently in the same space.
Solution Approach 2:
The basket is nested within the waterproof tray, which itself is nested within the luggage compartment. This nested structure allows multiple levels of containment, where the inner basket holds the objects, the middle tray provides waterproof protection, and the outer compartment provides storage space.
2Object-affected harmful factors
If a waterproof tray is used to contain wet objects, then protection of the compartment is improved, but water drainage becomes problematic
Solution Approach 1:
The bottom of the waterproof tray is segmented with multiple drain holes distributed across the surface. This segmentation allows water to drain through multiple points simultaneously, preventing water accumulation while maintaining the overall waterproof containment structure.
Solution Approach 2:
The tray bottom is designed with different local properties: most areas are waterproof to contain water, while specific localized areas have drain holes to allow water egress. The inclined bottom wall creates local quality variations in water flow direction, guiding water toward drainage areas.
3Object-affected harmful factors
If the tray is sealed to prevent moisture escape, then compartment cleanliness is improved, but odor accumulation increases
Solution Approach 1:
The tray lid is made of a porous material that allows vapor transmission. This enables moisture and odors to pass through the lid while still providing a physical barrier, preventing liquid water and larger contaminants from escaping into the compartment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively separates and drains water and mud from objects, allowing them to dry and preventing damage to the compartment, while maintaining cleanliness by preventing moisture and odor from escaping, and enhancing dirt removal through vibrations during vehicle operation.
Implementation Method 1
at least one bottom wall (11) of the recess (9) is inclined with respect to the lid (10)
Implementation Method 2
vibrations caused during the drive operation may lead to scrubbing movements of the object relative to the basket
Implementation Method 3
adhering subject matter can be scrubbed off the object by means of the basket
