Annular Lighting System for Saddle-Riding Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlight systems for saddle-riding vehicles are excessively heavy due to the dual housing and reflector arrangement, making them unsuitable for compact and lightweight designs required for such vehicles.
Innovation Solution
A lighting system comprising a first lighting apparatus with a housing, an annular second lighting apparatus, and an annular stay that supports the second lighting apparatus, eliminating the need for a separate housing for the second lighting apparatus and using light-emitting elements arranged radially to provide uniform illumination without a reflector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a dual housing and reflector arrangement is used for the first and second lighting apparatus, then the illumination function is achieved, but the weight of the lighting system becomes excessively heavy
Solution Approach 1:
The housing of the first lighting apparatus is made to also serve as the support structure for the second lighting apparatus. The annular stay is integrated with the housing, eliminating the need for separate housing structures for both lighting apparatus, thereby reducing overall weight while maintaining illumination functionality.
Solution Approach 2:
The housing is designed to perform multiple functions: it encloses the first light source, supports the annular stay, and provides structural mounting for the second lighting apparatus. This multi-functional design reduces the number of separate components needed, directly addressing the weight reduction goal.
2Shape
If the first housing is disposed forwardly of the reflector of the second lighting apparatus, then the structural arrangement is achieved, but it becomes difficult to set the reflection surface uniformly
Solution Approach 1:
The second lighting apparatus is arranged in an annular configuration around the first lighting apparatus, changing from a linear forward-backward arrangement to a radial three-dimensional layout. This dimensional change allows the reflection surface to be uniformly set by positioning multiple light-emitting elements equidistantly around the central axis, solving the uniformity problem.
Solution Approach 2:
The annular stay and second lighting apparatus use an asymmetric radial arrangement around the central first lighting apparatus, allowing flexible positioning of light-emitting elements at different angular positions while maintaining equal radial distance from the center, thus achieving uniform reflection surface geometry.
3Reliability
If separate housing structures are used for both first and second lighting apparatus, then each apparatus is structurally complete, but the overall device complexity increases
Solution Approach 1:
The housing structures of the first and second lighting apparatus are merged into a single integrated housing system. The annular stay is formed as part of the housing structure, reducing the total number of separate housing components from two independent housings to one integrated structure, thereby reducing device complexity.
Solution Approach 2:
The single housing structure performs multiple functions: it encloses the first light source, provides structural support, and serves as the mounting framework for the annular stay and second lighting apparatus. This universal housing design maintains structural reliability while reducing component count and overall complexity.

AI summary
A lighting system includes a first lighting apparatus, an annular second lighting apparatus, and an annular stay. The first lighting apparatus includes a light source covered with a housing. The annular second lighting apparatus is disposed around the housing and includes a plurality of light-emitting elements disposed annularly so as to be radially spaced apart from an outer periphery of the first lighting apparatus. The annular stay is supported by the housing to support the second lighting apparatus.
