Straddled Vehicle Tail Lamp Mounting Reduces Mud Guard Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddled vehicles face challenges with the strength and weight of mud guards due to the mounting of lamps and wiring, which complicates assembly and layout.
Innovation Solution
The tail lamp is mounted directly to the frame without interposing the mud guard, with the lamp pedestal and license lamp being integral to the tail lamp's housing, allowing the wiring to pass above the mud guard, reducing the load on the mud guard and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lamp pedestal and tail lamp are mounted on the mud guard, then the mud guard provides structural support, but the mud guard must be made high in strength which increases its weight
Solution Approach 1:
The lamp pedestal is extracted from the mud guard structure and mounted directly on the frame instead. This separation removes the load-bearing requirement from the mud guard for supporting lamp components, allowing the mud guard to be made lighter while the frame承担了 the structural support function.
2Ease of manufacture
If the lamp pedestal and headlamp are mounted individually on the mud guard, then the mounting structure is complete, but the arrangement is poor in ease of assembly
Solution Approach 1:
The lamp pedestal is merged with the tail lamp assembly, forming an integrated unit that is mounted as a single component on the frame. This combination reduces the number of separate mounting operations and simplifies the overall assembly process compared to mounting the pedestal and headlamp separately.
3Ease of operation
If the wiring of the license lamp passes through the insertion hole of the mud guard, then the wiring is connected, but it is difficult to lay out the wiring
Solution Approach 1:
The wiring routing is extracted from the mud guard structure. Instead of passing through an insertion hole in the mud guard, the wiring is routed through the frame structure, which provides a more accessible and easier path for wiring layout and installation.

AI summary
A straddled vehicle includes a tail lamp (35), disposed above a mud guard (32), and a license lamp (37), illuminating a license plate (38). A lamp base (55) of the tail lamp (35) includes a housing portion (61), holding and housing a light source (51), and a lamp pedestal portion (62), being integral to the housing portion (61) and on which the license lamp (37) is mounted, upper fastening portions (65), fastened to a frame (2) without interposition of the mud guard (32), and lower fastening portions (64), fastened to the mud guard (32). A first wiring (71), supplying power to the license lamp (37), extends to a position higher than the mud guard (32) while passing between the mud guard (32) and the lamp pedestal portion (62) without penetrating through the mud guard (32).
