Scooter Front Section Layout for Leg Space and Fuel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scooter type vehicles face challenges in compactly forming the front section structure while ensuring sufficient space for riders' legs and facilitating easy fuel supply.
Innovation Solution
The scooter type vehicle design includes a frame with a front fork, seat, cover, front fender, headlight, and oil filler, where the front cover portion houses the headlight and flashers, and the oil filler is positioned in the rear cover portion, allowing for a compact front section and forward placement of the oil filler to maximize leg space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the oil filler is positioned in the rear cover portion, then fuel supply is facilitated, but the space for rider's legs is reduced
Solution Approach 1:
The patent positions the oil filler opening in the rear cover portion at a location that is forward of the flashers in the longitudinal direction, utilizing the longitudinal dimension to resolve the conflict between fuel accessibility and leg space. This dimensional arrangement allows the oil filler to be easily accessible while maintaining sufficient leg room in the transverse and vertical dimensions.
2Length of moving object
If the front section structure is compacted, then the vehicle size is reduced, but the space for rider's legs is reduced
Solution Approach 1:
The patent segments the cover into distinct portions (front cover portion, rear cover portion, foot board) with clearly defined functions. The rear cover portion houses the oil filler opening at an optimized position, while the front cover portion contains the flashers and headlight. This segmentation allows compact arrangement of components without compromising leg space in the foot board area.
3Volume of moving object
If the oil filler is positioned forward to maximize leg space, then leg space is increased, but the cap may interfere with flasher installation
Solution Approach 1:
The patent employs asymmetric positioning of the oil filler opening relative to the flashers. The oil filler opening is located forward of the flashers in the longitudinal direction, creating an asymmetric layout that prevents interference between the cap and flasher installation while maximizing leg space. This asymmetric arrangement resolves the spatial conflict between these components.

AI summary
The present invention provides a scooter type vehicle for compactly forming a structure of a front section of a vehicle, facilitating oil supply to the vehicle, and largely ensuring a space for positioning rider's legs. In the scooter type vehicle, a front fender (27) is separately provided from a front cover portion (21) and covers the top of a front wheel (3). The front fender (27) is movable with the front wheel (3). A headlight (32) is provided in the transverse center of the front cover portion (21). A pair of flashers (31a, 31b) is provided in the front cover portion (21). The flashers (31a, 31b) are disposed in positions spaced from the transverse center of the vehicle to the rightward and the leftward, respectively. An oil filler (51) is provided in a rear cover portion (24). The oil filler (51) includes an oil filler opening (52) and an oil filler cap (53) for opening/closing the oil filler opening (52). When the oil filler cap (53) closes the oil filler opening (52), the front end of the upper surface of the oil filler cap (53) is disposed in a position spaced from the transverse center of the vehicle either to the rightward or the leftward, and is disposed in a position vertically spaced from the flashers (31a, 31b).
