Saddled Vehicle Wing Member Segmentation and Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddled vehicle wing members, particularly those of a cantilever type, are prone to deformation and vibration due to increased airflow forces, which compromises their aerodynamic effectiveness and stability.
Innovation Solution
A wing member configuration featuring a first wing and a second wing connected by a connection section, with the first wing positioned above the second wing in a longitudinal direction, and both wings inclined to enhance rigidity and aerodynamic performance, while a cover member is used to rectify airflow and reduce air resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the wing member is enlarged to enhance aerodynamic effect, then the down force increases, but the force acting on the wing member increases causing deformation or vibration
Solution Approach 1:
The wing member is divided into a first wing and a second wing connected by a connection section. This segmentation allows the structure to handle increased aerodynamic forces by distributing loads across multiple components, preventing deformation and vibration while maintaining enhanced down force capability.
Solution Approach 2:
The connection section connects the first wing and second wing in a spatial arrangement that extends in multiple dimensions. The first wing is positioned above and forward of the second wing, creating a three-dimensional structure that improves rigidity and resistance to aerodynamic forces while maintaining aerodynamic effectiveness.
2Device complexity
If a cantilever type wing member is used, then the structure is simple, but deformation or vibration occurs when airflow force increases
Solution Approach 1:
The wing member is segmented into multiple parts (first wing, connection section, second wing) that work together to provide structural stability. This segmentation maintains relative structural simplicity while significantly improving resistance to deformation and vibration under increased airflow forces.
3Strength
If the first wing and second wing are connected to increase rigidity, then deformation is prevented, but the device complexity increases
Solution Approach 1:
The connection section integrates the first wing and second wing into a unified structural assembly. This merging provides the necessary rigidity and strength to prevent deformation while maintaining a relatively simple overall structure that does not require complex additional components or mechanisms.
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
This configuration enhances the rigidity and support strength of the wing members, prevents deformation and vibration, and achieves a higher down force effect by optimizing airflow rectification and reducing air resistance, thereby improving the overall aerodynamic performance.
Implementation Method 1
a plate-shaped wing member is attached to a surface of the cowling, for rectifying airflow (induced by travelling of the vehicle) into a desired direction and for obtaining a down force that presses down the vehicle body
Implementation Method 2
a front edge (50f) of the first wing (50) is inclined such that its transverse-directionally outer side portion is located on a vehicle body rear side relative to its transverse-directionally inner side portion, in plan view of the vehicle body, and a rear edge (50r) of the first wing (50) is inclined such that its transverse-directionally outer side portion is located on a vehicle body front side relative to its transverse-directionally inner side portion

AI summary
A wing member includes a first wing, a second wing, and a connection section connecting one-end sides of the first wing and the second wing. Both the wings are disposed with a spacing therebetween in the longitudinal vehicle direction, and the first wing is located on a vehicle body front upper side relative to the second wing. The connection section connects the one-end sides of both the wings that extend from a cowling toward a transverse-directionally outer side. A front edge of the first wing is inclined such that its transverse-directionally outer side portion is located on the vehicle body rear side relative to its transverse-directionally inner side portion, in plan view of the vehicle body. A rear edge of the first wing is inclined such that its transverse-directionally outer side portion is located on the vehicle body front side relative to its transverse-directionally inner side portion, in plan view.
