Vehicle Floor Ventilation Dirt Collection Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems in vehicles face issues with dirt particles, such as small stones, entering air vents at floor level, causing unpleasant noises due to restricted airflow from grilles or screens used for filtration.
Innovation Solution
A ventilation system with a collecting structure integrated into the floor covering or panel, featuring grooves and ribs to catch dirt particles before they enter the air duct, preventing them from reaching the air vent and reducing noise without restricting airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If grilles or screens are used in the air vent entrance area to filter out dirt particles, then dirt particles can be filtered out, but the cross section of the air duct is restricted and ventilation function is impaired
Solution Approach 1:
The harmful function of filtering dirt particles is extracted from the air duct system and placed into a separate collecting structure (grooves) in the floor covering. This allows the air duct to remain open and unobstructured, maintaining full ventilation capacity while dirt particles are captured in the grooves before they can enter the air duct.
Solution Approach 2:
The grooves in the floor covering serve as an intermediary structure between the floor area and the air duct entrance. They intercept and collect dirt particles in the intermediate zone, preventing direct contact between dirt and the air duct while allowing air to flow freely through the duct.
2Ease of operation
If air vents are placed at floor level to meet ergonomic and optical demands, then good interior ventilation is achieved, but dirt particles under feet can enter the air vent and cause unpleasant noises
Solution Approach 1:
The grooves, which initially seem to be just structural features of the floor covering, are converted into functional collecting structures that actively capture dirt particles. The same floor covering that provides ergonomic benefits also serves the dual function of filtering dirt through its integrated grooves.
Solution Approach 2:
The floor covering and the filtering function are merged into a single integrated structure. The grooves are formed directly in the floor covering material, combining the flooring function with the dirt collection function, eliminating the need for separate filtering components.
3Object-affected harmful factors
If a collecting structure with grooves is formed in the floor covering to catch dirt particles, then dirt particles are prevented from entering the air duct, but the floor covering structure becomes more complex
Solution Approach 1:
The collecting structure is merged with the floor covering itself rather than being a separate component. The grooves are formed directly in the floor covering material through molding or extrusion processes, creating an integrated structure that performs both flooring and dirt collection functions without adding structural complexity.
Solution Approach 2:
The floor covering is given multiple functions: it serves as the flooring surface and simultaneously acts as the collecting structure for dirt particles. This multi-functionality eliminates the need for additional separate components, maintaining simplicity in the overall system.
