Scooter Cornering Light Layout for Stable Illumination Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scooter type vehicles experience discomfort due to significant changes in cornering light illumination range with lean angle, and large cornering lights increase the vehicle's front portion size.
Innovation Solution
The scooter type vehicle features left and right cornering lights disposed at low positions on the front cover, with a controller adjusting their light quantities based on lean angles, ensuring minimal position change and compact placement, thus reducing illumination range variation and downsizing the front portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If cornering lights are disposed at a high position, then the distance between the cornering light and the ground increases, but the change in position of the cornering light increases with the change in lean angle, causing greater change in illumination range
Solution Approach 1:
The patent changes the vertical position parameter of the cornering light from high to low on the front cover. This parameter change reduces the lever arm effect during leaning, thereby minimizing the positional change of the cornering light and suppressing illumination range variation, which improves rider comfort.
2Ease of operation
If cornering lights are disposed at a low position, then the change in position of the cornering light decreases, but multiple light sources are needed to suppress decrease in illumination range, increasing device complexity
Solution Approach 1:
The patent combines multiple cornering light sources into a single integrated light unit disposed at a low position on the front cover. This merging approach maintains compact illumination coverage while suppressing positional change during leaning, avoiding the need for multiple separate light sources and reducing device complexity.
3Illumination intensity
If cornering lights are enlarged in the vehicle width direction, then the illumination range is maintained, but the size of the front portion of the vehicle increases
Solution Approach 1:
The patent changes the vertical position parameter of the cornering light to low on the front cover, which suppresses positional change during leaning. This allows the use of a compact light unit without requiring enlargement in the vehicle width direction, thereby maintaining illumination range while reducing front portion size.
