Front Fender Bracket Layout for Lamp Placement and Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle front structures face limitations in design freedom due to the need to position components like headlamp stays outside the protection area to ensure adequate impact absorption, which restricts the placement and design of other components.
Innovation Solution
A vehicle front structure that includes a fender flange, an object component (such as a lamp unit), and a bracket connecting the fender flange and the object component. The bracket features a bent portion that extends in one direction and then turns back, allowing the object component to be positioned within the protection area without compromising impact absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp stay is positioned in the protection area to improve design freedom, then the degree of freedom in placement of the lamp unit is improved, but the impact-absorbing properties deteriorate because the lamp unit cannot sufficiently absorb impact
Solution Approach 1:
A bracket is introduced as an intermediary component between the fender flange and the lamp stay. The bracket includes a bent portion that extends in a direction toward one side in the vehicle-width direction while extending toward the vehicle-upward side, and then turns back in a direction toward an opposite side in the vehicle-width direction while extending toward the vehicle-upward side. This bent portion can deform during impact to absorb energy, allowing the lamp stay to be positioned in the protection area while maintaining impact-absorbing properties.
2Reliability
If the lamp stay is positioned outside the protection area to ensure impact absorption, then the impact-absorbing properties are improved, but the degree of freedom in design is reduced
Solution Approach 1:
The bracket serves as a mediator that decouples the position of the lamp stay from the fender flange. By using the bracket with its bent portion that can deform during impact, the design allows the lamp stay to be freely positioned within the protection area without compromising impact absorption, thus resolving the design freedom limitation.
3Device complexity
If components are directly fastened to the fender flange to simplify the structure, then the device complexity is reduced, but the impact-absorbing properties deteriorate due to poor impact absorption of directly fastened components
Solution Approach 1:
Instead of directly fastening the lamp stay to the fender flange, a bracket is introduced as an intermediary. This bracket with its bent portion provides impact absorption capability while maintaining relatively simple structure. The bracket can be formed from a single piece of metal through bending, keeping manufacturing simple while adding the necessary impact absorption function.
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
This configuration enhances the degree of freedom in designing the vehicle front by allowing the object component to be placed within the protection area, while also improving impact absorption through the deformation of the bracket during collisions.
Implementation Method 1
forming the bracket into a shape that is folded back in the vehicle-width direction enables impact, in the event of collision with the protection object, to be absorbed by deformation of the bracket

AI summary
The vehicle front structure is a part of a front fender panel, and includes a fender flange extending inward in the vehicle-width direction from an upper edge of a aesthetic surface of the front fender panel, a lamp unit disposed on the vehicle-downward side of the fender flange, and a bracket connecting the fender flange and the lamp unit. The bracket has a bent portion that extends in a direction toward one side in the vehicle-width direction toward the vehicle-upward side, and then turns back in a direction toward the opposite side in the vehicle-width direction toward the vehicle-upward side.
