Motorcycle Side Cover Lamp Visibility Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles with direction indicator lamps positioned at the side cover at the front part tend to increase vehicle width, necessitating larger passing distances and parking spaces, as existing designs protrude outwardly in the vehicle widthwise direction.
Innovation Solution
A saddle riding type vehicle design featuring a side cover with a recessed second side surface allowing the direction indicator lamp to protrude outwardly from the inner side, reducing overall vehicle width while enhancing visibility from other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the direction indicator lamp protrudes outwardly from the side cover in the vehicle widthwise direction, then the visibility of the direction indicator lamp is improved, but the vehicle width increases
Solution Approach 1:
The side cover is designed with a recessed portion that allows the direction indicator lamp to protrude in the vehicle widthwise direction while the overall side cover profile remains compact. This creates a localized dimensional change that improves lamp visibility without significantly increasing the vehicle's overall width envelope
Solution Approach 2:
The direction indicator lamp is nested within a recessed portion of the side cover, allowing the lamp to be positioned outwardly for better visibility while the recessed structure itself is integrated into the side cover's overall compact design, preventing excessive width increase

AI summary
A motorcycle is provided that has a direction indicator lamp (59) at a side cover, so that the direction indicator lamp (59) is more easily visually recognized from other and the direction indicator lamp (59) is unlikely to contact other motorcycles and the like. A side cover (53) includes a first side cover that covers a vehicle widthwise outer side of a front part and has a front part connected to a front cover (52) and a second side cover provided adjacent to the first side cover as viewed in the vehicle widthwise direction. A support surface facing an outer surface of the second side cover in the vehicle widthwise direction is positioned more on the inner side in the vehicle widthwise direction than a first side surface facing an outer side of the first side cover in the vehicle widthwise direction. The support surface has an opening. A part of the direction indicator lamp (59) protrudes to the outer side in the vehicle widthwise direction from the opening.
