Riding Vehicle Cowling Opening Positioning for Banking Lightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cowling structure of riding-type vehicles obstructs air flow during early-stage turning due to openings formed near internal structures, leading to unsatisfactory lightness and potential damage to the external appearance when enlarged to improve this.
Innovation Solution
A cowling structure with side cowls lengthened to the front of the head pipe and openings positioned level with the head pipe, overlapping with the steering gear, allowing improved air flow and maintaining the internal structure's protection without excessive enlargement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening is enlarged to improve the lightness of banking, then the lightness of banking is improved, but the internal structure is easily exposed to view through the opening
Solution Approach 1:
The patent positions the opening in the fore direction (front view) rather than only in the transverse direction (side view). By making the opening extend in the fore direction to overlap with the steering gear in front view, air can be supplied effectively without enlarging the opening in the transverse direction, thus preventing exposure of internal structures while maintaining banking lightness
2Device complexity
If the opening is formed near internal structures, then the cowling structure is compact, but the internal structure obstructs the flow of air through the opening
Solution Approach 1:
The patent extracts the opening from the traditional position near internal structures and relocates it to the fore direction where it overlaps with the steering gear. This extraction allows air flow to be improved without being obstructed by internal structures, while the opening still serves the cowling structure effectively
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the lightness of the vehicle during early-stage turning while minimizing exposure of internal structures, thus protecting the external appearance and maintaining the structural integrity.
Implementation Method 1
the opening is in such a position that it is level with the head pipe and overlaps with the steering gear in the fore of the head pipe... allowing the flow of air passing through the opening to be made better

AI summary
A cowling structure includes a head pipe mounted to the front of a body frame, a steering gear held such that it is capable of pivoting about the axis of the head pipe, side cowls each arranged at the transverse outside of the body frame, together with an opening so formed in each side cowl that it communicates with the transverse outside and inside of each side cowl. When viewed in a side view, the side cowls are lengthened up to the fore of the head pipe, and the opening is in such a position that it is level with the head pipe and overlaps with the steering gear in the fore of the head pipe. Such cowling structure permits less damages to the external appearance while providing the improvement in the lightness of banking at the time in the early stage of turning of a vehicle body.
