Motorcycle Lighting Device with Overlapping Headlights and Flashers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting devices do not adequately enhance the conspicuity and area illumination performance by integrating flasher lights with headlamps and position lights, lacking a cohesive design that maximizes light emission range and visual impact.
Innovation Solution
A lighting device configuration featuring overlapping headlamps, position lights, and flasher lights, with the latter placed under the position lights and extending to cover the front fender, utilizing L-shaped inner lenses and reflectors to create continuous light emission surfaces from top to bottom, enhancing visual effects and conspicuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If headlight, position light, and flasher light are arranged separately without overlap, then each light can be independently designed and manufactured, but the overall conspicuity and continuous light emission surface are reduced
Solution Approach 1:
The patent combines headlight, position light, and flasher light into an integrated lighting device where the light sources and their optical components are arranged in overlapping relationships. The headlight (H) and position light (P) overlap in the vehicle width direction, and the position light (P) and flasher light (F) overlap in the vehicle width direction, creating a unified lighting assembly that functions as a single entity rather than separate components.
Solution Approach 2:
The patent utilizes the vehicle width direction as an additional spatial dimension to arrange the lights in overlapping configurations. By viewing the vehicle from the front, the lights are positioned to overlap in the width direction, which allows multiple light functions to be integrated without increasing the vertical or longitudinal footprint, thereby creating a continuous light emission surface that enhances conspicuity.
2Illumination intensity
If position light emits light in a band-shaped range only, then the headlight outline is emphasized, but the area illumination performance and overall conspicuity are insufficient
Solution Approach 1:
The position light serves multiple functions: it emphasizes the headlight outline through its band-shaped emission, provides area illumination through its extended coverage, and contributes to the continuous light emission surface when overlapped with the flasher light. The flasher light similarly serves both as a directional indicator and as part of the continuous illumination surface, demonstrating multi-functionality that resolves the contradiction between outline emphasis and area illumination.
3Device complexity
If multiple lights are integrated in a compact arrangement, then component count is reduced, but the continuous light emission surface from top to bottom may be compromised
Solution Approach 1:
The patent arranges the flasher light (F) underneath the position light (P), which itself is underneath the headlight (H), creating a nested vertical arrangement. This nesting allows the lights to be integrated in a compact configuration while maintaining their individual functions. The overlapping in the vehicle width direction ensures that the nested arrangement still produces a continuous light emission surface when viewed from the front or sides.

Function Achieved in This Case
The configuration provides improved conspicuity and area illumination by creating a continuous light emission range from top to bottom, enhancing the visual impact and appearance of the vehicle while maintaining a reduced component count and assembly complexity.
Implementation Method 1
the headlight includes a low beam headlight and a high beam headlight which use reflectors for forward reflection of illumination light from light sources

AI summary
A lighting device for a vehicle includes: a pair of left and right headlights (H); a pair of left and right position lights (P) situated underneath the headlights (H); and a pair of left and right flasher lights (F) situated underneath the position lights (P), and the headlights (H), the positon lights (P) and the flasher light (F) are placed on the front of a motorcycle (1). The headlights (H) and the position lights (P) are placed to overlap each other in a vehicle width direction as viewed in a front view of the vehicle. The position lights (P) and the flasher lights (F) are placed to overlap each other in the vehicle width direction. The flasher lights (F) are placed to overlap, in the vehicle width direction, a part of a front fender (13) covering a front wheel (WF) of the motorcycle (1).
