Motorcycle Lighting Mounting Segmentation for Back Cover Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles with long lighting equipment along the front cover face reduced rigidity and supporting strength for the back cover, limiting the placement of mounting portions and increasing the distance between the front and back covers.
Innovation Solution
Incorporating first and second mounting portions on the lighting equipment, where the front cover is connected via the first mounting portion and the back cover via the second, with fastening portions having larger diameters to allow for alignment flexibility and reduced positional errors, thereby maintaining support strength and flexibility in mounting location selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting equipment is made long along the front cover to incorporate multiple bulbs and improve esthetic appeal, then the lighting functionality and appearance are enhanced, but the front cover rigidity and supporting strength for the back cover are decreased
Solution Approach 1:
The mounting structure is segmented into two distinct systems: first mounting portions that extend backward from the front cover for securing lighting equipment, and second mounting portions that extend forward from the back cover for securing the back cover. This segmentation allows each mounting system to be optimized independently, with the first mounting portions positioned to avoid interfering with the back cover mounting locations, thereby maintaining front cover rigidity while supporting long lighting equipment configurations.
2Ease of manufacture
If long mounting portions are formed in the front cover to reach the back cover, then the back cover can be mounted, but the rigidity of the mounting portions and supporting strength are decreased
Solution Approach 1:
The mounting structure is divided into separate first mounting portions extending backward from the front cover and second mounting portions extending forward from the back cover. This eliminates the need for long mounting portions spanning the entire distance between front and back covers, as each mounting system only needs to extend a short distance from its respective cover, thereby maintaining mounting portion rigidity and supporting strength while still enabling back cover mounting.

AI summary
There is provided a motorcycle (10) which is capable of reducing a decrease in supporting strength for supporting a back cover (80) while increasing freedom in selecting positions for mounting portions to which the back cover (80) is mounted, even when the lighting equipment (50) is made long along the front cover (40). A motorcycle (10) includes lighting equipment (50) which has front cover mounting portions (68,70) and back cover mounting portions (76); a front cover (40) which has an opening (44a) for exposing a front surface of the lighting equipment (50); and a back cover (80) mounted to cover the lighting equipment (50) and the front cover (40) from behind. The front cover (40) is mounted so as to expose the front surface of the lighting equipment (50) from the opening (44a), and is connected with the lighting equipment (50) via the front cover mounting portions (68,70). The back cover (80) is connected with the lighting equipment (50) via the back cover mounting portions (76).
