Vehicle Instrument Panel Blower Outlet Guide Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle anti-fogging devices compromise air conveyance efficiency and external styling due to the orientation and visibility of the blower outlet, which is normally open towards the rear and exposed within the cabin.
Innovation Solution
A vehicle instrument panel structure featuring a blower outlet positioned between the meter section and the vehicle door, with a guide member that blocks the outlet from view and directs airflow efficiently towards the side window glass, enhancing styling and anti-fogging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blower outlet is opened substantially toward the vehicle rear side to convey conditioned air toward the front passenger seat, then air conveyance toward the seat is achieved, but air conveyance efficiency toward the side window glass deteriorates and external styling is compromised due to exposure
Solution Approach 1:
The blower outlet is divided into multiple outlets with different orientations. One outlet faces the vehicle rear side for conveying conditioned air to the front passenger seat, while another outlet is positioned to convey air toward the side window glass. This segmentation allows each outlet to perform its specific function independently, resolving the contradiction between seat ventilation and anti-fogging efficiency while maintaining aesthetic appearance through strategic positioning and orientation of each segment.
2Productivity
If the blower outlet is positioned to face the side window glass directly for efficient anti-fogging, then air conveyance efficiency improves, but the outlet becomes exposed to view from the vehicle cabin interior, deteriorating external styling
Solution Approach 1:
The blower outlet system is segmented into multiple outlets with different orientations. One outlet is positioned and oriented to face the side window glass directly for efficient anti-fogging, while another outlet faces the vehicle rear side for seat ventilation. This segmentation allows the anti-fogging outlet to be optimally positioned for functionality while the overall system maintains aesthetic appearance through strategic positioning of each segment.
Solution Approach 2:
The guide member structure serves multiple functions: it guides airflow from the blower outlet toward the side window glass for efficient anti-fogging, and simultaneously acts as a decorative element that conceals the blower outlet from view, maintaining external styling. This multi-functionality resolves the contradiction between anti-fogging efficiency and aesthetic appearance.
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 efficiently removes fog from the side window glass while improving external styling by directing airflow effectively and concealing the blower outlet, thus enhancing both functionality and aesthetics.
Implementation Method 1
airflow blown out through the blower outlet substantially toward the vehicle rear side is smoothly guided toward the vehicle width direction outer side by the guide member. This enables the airflow to be made to efficiently contact a side window glass at the vehicle width direction outer side of the instrument panel, thereby enabling fog that has condensed on the side window glass to be efficiently removed

AI summary
A vehicle instrument panel structure is provided including a blower outlet and a guide member. The blower outlet is provided between a meter section on an instrument panel provided at a front section of a vehicle cabin and an interior member of a vehicle door, and is capable of blowing an airflow substantially toward a vehicle rear side. The guide member is provided at the vehicle rear side of the blower outlet so as to block the blower outlet from view of an occupant sitting in a vehicle seat provided inside the vehicle cabin, and extends at an angle toward the vehicle rear side on progression from a location corresponding to the blower outlet toward a vehicle width direction outer side.
