Vehicle Exterior Light Layout for Side Visibility at Hood-Fender Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exterior light structures for vehicles, where communication lamps are disposed around headlights, make it difficult for pedestrians to visually recognize the lighting or blinking of these lamps when their visual line is directed towards the side surface of the vehicle, particularly during turns or intersections.
Innovation Solution
The exterior light structure for vehicles includes lamp bodies disposed between the upper parts of fender members and the side edge parts of the hood member, with light radiated through gaps between these components, ensuring that the boundary parts between the fender members and the hood member shine and come into sight when the lamp bodies are lit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lamp bodies are disposed around headlights on the front surface of the vehicle, then the communication function is achieved, but the visual recognizability by pedestrians viewing from the side is insufficient
Solution Approach 1:
The lamp bodies are relocated from the traditional front surface arrangement around headlights to a new spatial position between the fender members and hood member. This dimensional relocation allows the lamp light to be visible from side viewing angles, solving the problem of poor visual recognizability for pedestrians approaching from the side while maintaining the communication function.
Solution Approach 2:
The patent introduces gaps between the fender members and hood member as intermediary light transmission paths. These gaps serve as mediators that allow the lamp light to reach the exterior space and become visible from the side, without requiring the lamp bodies to protrude outward or complicate the overall structure.
2Reliability
If lamp bodies are disposed between fender members and hood member with light radiated through gaps, then side visual recognizability is improved, but the exterior appearance may be affected
Solution Approach 1:
The patent applies local quality by making the gaps between fender members and hood member light-transmissive while keeping the rest of the body panels opaque. This selective light transmission through specific localized gaps allows the lamp light to be visible from the side without compromising the overall exterior appearance, as the gaps are strategically positioned and sized to balance visibility and aesthetics.
3Reliability
If lamp bodies protrude from side parts of vehicle body, then light visibility from side is improved, but vehicle width increases
Solution Approach 1:
The lamp bodies are nested within the existing vehicle body structure, specifically positioned between the fender members and hood member rather than protruding outward. This nesting approach allows the lamp light to be visible from the side through the gaps between body panels while maintaining the original vehicle width dimensions, avoiding any increase in overall vehicle size.
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 allows pedestrians to clearly recognize the light from the lamp bodies even when their visual line is directed towards the side surface of the vehicle, thereby enhancing traffic safety and maintaining a favorable exterior appearance without protruding the lamp bodies.
Implementation Method 1
radiate light to the outside of the vehicle through gaps between the fender members and the hood member
Implementation Method 2
allowing light of the lamp bodies to be transmitted therethrough

AI summary
An exterior light structure is mounted in a vehicle including fender members and a hood member. The fender members are disposed in side parts of a vehicle body. The hood member is disposed adjacent to upper parts of the fender members. The exterior light structure includes lamp bodies 22. The lamp bodies 22 are disposed between the upper parts of the fender members and side edge parts of the hood member substantially in a vehicle body forward-rearward direction. The lamp bodies 22 radiate light to the outside of the vehicle through gaps d between the fender members and the hood member.
