Front Spoiler Device with Annular Insertion for Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional front spoiler devices with central partitioning suffer from aesthetic quality deterioration due to visible partition lines and dimensional errors, which compromise both aerodynamics and appearance.
Innovation Solution
A front spoiler device design featuring a diffuser portion with a baffle plate and insertion space forming portion that extends along the bumper fascia's corner, allowing the spoiler body's vertical wall to be inserted, creating an annular connection that hides the partition line and enhances rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the front spoiler device is divided into two parts at the lateral center position to absorb dimensional errors, then the dimensional control is improved, but a partition line appears and appearance quality deteriorates
Solution Approach 1:
The patent introduces a buffer portion as an intermediary element between the left and right spoiler bodies. This buffer portion absorbs dimensional errors and prevents direct contact between the divided spoiler parts, thereby eliminating visible partition lines while maintaining dimensional control flexibility
Solution Approach 2:
The spoiler device is segmented into left and right spoiler bodies that are relatively movable in the vehicle width direction, allowing independent adjustment to absorb dimensional errors without creating visible partition lines through the buffer portion design
2Loss of energy
If the front bumper extends laterally to cover the front wheel for better aerodynamics, then the aerodynamic characteristics are improved, but the device complexity increases
Solution Approach 1:
The spoiler device is divided into modular components (left and right spoiler bodies, buffer portion, mounting portions) that can be independently manufactured and assembled, simplifying the overall device complexity while achieving the extended lateral configuration for improved aerodynamics
Solution Approach 2:
The left and right spoiler bodies are designed to be relatively movable in the vehicle width direction, providing dynamic adjustment capability that simplifies installation and accommodation of dimensional variations while maintaining the aerodynamic benefits of the extended configuration

AI summary
Provided is a front spoiler device that does not deteriorate the outward appearance quality with excellent aerodynamic performance. The front spoiler device includes a bumper fascia 11 forming the outer surface of a front bumper 10, a spoiler body 20 extending along the lower end of the bumper fascia 11 in the vehicle width direction, the spoiler body being provided with a vertical wall portion 21 facing the front of the vehicle, a diffuser portion 30 connected to each lateral end of the spoiler body 20 that extends in the vehicle downward direction and in the vehicle width direction along a corner portion of each lateral end on the lower end of the bumper fascia 11; and an insertion space forming portion 36 provided on the diffuser portion 30 that forms an insertion space into which at least the lateral end of the vertical wall portion 21 is insertable in the vehicle width direction to thereby form an annular shape with the baffle plate portion 31.
