Vehicle Floor Mat Airflow Structure for Rear Footwell Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle floor mat structures hinder the efficient distribution of air-conditioned air from the front seat to the rear seat, leading to reduced comfort for rear-seat passengers due to blocked air pathways and increased manufacturing costs.
Innovation Solution
A vehicle floor mat structure featuring an opening below the front seat for air passage and an inclined portion closer to the rear seat, which guides air-conditioned air effectively towards the rear seat, enhancing comfort and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional floor mat structure is used, then the manufacturing cost is reduced, but the air-conditioned air cannot be efficiently guided to the rear seat
Solution Approach 1:
The floor mat is segmented into multiple functional regions: a first region with an opening for air passage, a second region with an inclined portion for guiding air flow, and a third region covering the remaining area. This segmentation allows the floor mat to efficiently guide air-conditioned air to the rear seat while maintaining cost-effectiveness through selective functional zoning.
2Ease of manufacture
If the floor mat completely covers the installation space, then manufacturing is simpler, but air-conditioned air flow is blocked
Solution Approach 1:
The floor mat applies different structural qualities to different regions: the first region contains an opening to allow air passage, the second region has an inclined portion to guide air flow, and the third region provides complete coverage. This local quality differentiation ensures air flow efficiency where needed while maintaining manufacturing simplicity in other areas.
3Device complexity
If air conditioning ducts are installed in conventional locations, then the system is simpler, but rear seat passenger comfort is reduced
Solution Approach 1:
The air conditioning system utilizes the floor mat surface as a new dimension for air distribution. By incorporating openings and inclined portions in the floor mat, the system guides air-conditioned air from the front seat area to the rear seat area, improving passenger comfort without adding complex ductwork or increasing system complexity.
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 proposed structure improves air conditioning performance by guiding air-conditioned air efficiently to the rear seat, enhancing passenger comfort by approximately 57% compared to structures without the inclined portion, while also reducing manufacturing costs.
Implementation Method 1
The inclined portion includes an upward inclined surface toward the rear seat
Implementation Method 2
air-conditioned air blown from below a front seat of a vehicle toward a foot of a passenger seated on a rear seat

AI summary
A vehicle floor mat structure configured to guide air-conditioned air blown from below a front seat of a vehicle toward a foot of a passenger seated on a rear seat of the vehicle. The vehicle floor mat structure includes an opening and an inclined portion. The opening is provided in a floor mat below the front seat and serves as an air passage for the air-conditioned air. The inclined portion is provided closer to the rear seat than the opening is to the rear seat. The inclined portion is provided on the floor mat. The inclined portion includes an upward inclined surface toward the rear seat.
