Saddle-riding Vehicle Lamp Arrangement for Compact Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-riding type vehicles face challenges in enlarging the headlamp or side lamps without increasing the vehicle's width, while maintaining clear differentiation between the headlamp and side lamps, as existing configurations either result in overlapping visibility or require widening the vehicle.
Innovation Solution
The vehicle design includes a headlamp mounted on a front cover with side lamps positioned laterally and partially below the headlamp, allowing for larger angle visibility and differentiation by displacing the side lamps downward and using a substrate with light sources oriented to minimize width expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the headlamp or side lamps are enlarged while maintaining alignment in the vehicle width direction, then the lamp size is increased, but the vehicle width inevitably increases
Solution Approach 1:
The patent changes the spatial arrangement of lamps from a horizontal alignment to a vertical arrangement. The side lamps are positioned at least partially below the headlamp in the vehicle width direction, utilizing the vertical dimension to accommodate larger lamp sizes without increasing vehicle width. This dimensional transition resolves the contradiction by allowing lamp enlargement while maintaining compact vehicle width.
2Loss of information
If the front cover is disposed between the headlamp and side lamps to achieve better differentiation, then lamp differentiation is improved, but the vehicle width inevitably increases
Solution Approach 1:
Instead of using the front cover to separate lamps horizontally, the patent positions side lamps vertically below the headlamp. This vertical positioning achieves lamp differentiation and visibility without requiring additional horizontal space, thus improving lamp differentiation while avoiding vehicle width increase.
Solution Approach 2:
The patent integrates the side lamps with the front cover structure, where the side lamps are mounted on the front cover in a vertical arrangement. This merging approach allows the front cover to serve both as a mounting structure and a differentiating element, achieving lamp differentiation without increasing vehicle width.
3Length of stationary object
If the side lamps are disposed rearward of the headlamp to achieve compactness, then vehicle width is reduced, but the visibility angle of side lamps decreases
Solution Approach 1:
The patent positions side lamps vertically below the headlamp rather than displacing them rearward. This vertical positioning maintains lateral visibility angles while achieving compact vehicle width, as the side lamps remain laterally outward relative to the headlamp centerline while occupying lower vertical space.

AI summary
An inner lateral portion of a left lamp cover and an inner lateral portion of a right lamp cover are exposed to a space for rotating of a front fork device. A lower edge portion of a headlamp cover is disposed rearward of a front edge of a lower edge portion of a headlamp opening. A first viewpoint is defined as a viewpoint that is located leftward of a vehicle center in a vehicle width direction and is located forward of and higher than a headlamp and a right lamp. The lower edge portion of the headlamp opening is visible between the right lamp cover and the headlamp cover in a view from the first viewpoint.
