Vehicle Front Structure with Partial Airflow Guides to Reduce Drag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs experience turbulence and increased resistance due to air flow disturbances around the vehicle body when air flows laterally away from the front, particularly when guided through duct-like structures.
Innovation Solution
A vehicle front structure with an intake opening, discharge opening, and guides having partial inner and outer guide surfaces that reduce contact area and friction by guiding air flow through the vehicle body, minimizing turbulence and resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a duct-like guide is used to guide air flow from intake opening to discharge opening, then air flow guidance is improved, but resistance increases due to friction
Solution Approach 1:
The patent extracts the guide surfaces from a complete duct-like enclosure, providing only partial guidance where needed. The inner guide surface is positioned to guide air flow without forming a closed duct, and the outer guide surface is selectively positioned to reduce friction while maintaining guidance functionality.
Solution Approach 2:
The patent applies partial action by providing guide surfaces only in specific regions rather than throughout the entire flow path. The inner guide surface extends partially between the intake and discharge openings, and the outer guide surface is selectively positioned to provide guidance only where necessary, reducing overall friction.
2Stability of the object's composition
If air flow is guided through the vehicle body, then turbulence is reduced, but contact area with guide surfaces increases
Solution Approach 1:
The patent removes unnecessary guide surfaces that would increase contact area. The inner guide surface is positioned to provide stabilization without extending throughout the entire flow path, and the outer guide surface is selectively positioned to minimize contact area while maintaining air flow stability.
Solution Approach 2:
The patent applies local quality by providing guide surfaces only in specific regions where they are most effective for stabilization. The inner guide surface is positioned at critical locations within the flow path, and the outer guide surface is selectively positioned to provide local stabilization without maximizing overall contact area.
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 structure suppresses turbulence and reduces air resistance by guiding air flow through the vehicle body, ensuring smooth airflow and minimizing contact with guide surfaces.
Implementation Method 1
resistance is generated due to the friction of the air flow with the guide
Implementation Method 2
the air flow around the vehicle body becomes turbulent

AI summary
The traveling air flow is introduced into the inside of the vehicle body through the side grille opening formed at the side edge of the front bumper. The introduced air flow is guided by the side grille cover, side duct cover and side duct, and discharged from the side duct opening formed on the side of the front bumper. The inner guide surface and outer guide surface, which guide the air flow, are only partially disposed in the direction along the path of the air flow.
