Saddle-ride Vehicle Duct Intersecting Frame for Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional saddle-ride type vehicles face challenges in achieving both sufficient cooling and support rigidity due to the use of dedicated ducts, which increase weight and complexity, and result in higher air resistance and reduced support rigidity.
Innovation Solution
A saddle-ride type vehicle design featuring an outside air intake duct with a duct body that intersects with the vehicle body frame, secured by duct securing portions on both sides, providing excellent support rigidity and guiding air efficiently to cooling components like the generator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a dedicated duct is used to guide travelling air to vehicle components, then cooling effect is improved, but device complexity and weight increase
Solution Approach 1:
The patent merges the duct structure with the vehicle body frame by forming the duct holding portion directly as an integrated structure with the frame. The duct body is positioned to intersect with the frame, and the holding portion surrounds and secures the duct at the intersecting site, eliminating the need for separate mounting brackets or fastening components.
2Temperature
If a dedicated duct is used to guide travelling air to vehicle components, then cooling effect is improved, but weight increases
Solution Approach 1:
The duct holding portion is formed as an integrated structure with the vehicle body frame, combining the functions of structural support and duct mounting into a single component. This integration eliminates the need for separate mounting brackets or fastening components, thereby reducing overall weight while maintaining structural integrity and cooling functionality.
3Device complexity
If the duct is not securely supported by the frame, then device complexity is reduced, but support rigidity deteriorates
Solution Approach 1:
The vehicle body frame serves multiple functions: it provides structural support for the vehicle and simultaneously acts as a mounting structure for the duct through the integrated duct holding portion. The frame's intersection with the duct creates a multi-functional element that both supports the vehicle structure and secures the cooling duct in place.
4Temperature
If a large amount of travelling air is circulated for cooling, then cooling effect is improved, but air resistance increases
Solution Approach 1:
The duct body is positioned to intersect with the vehicle body frame at a specific location, creating a localized air intake structure. The air intake opening is formed on the front end of the cowl at the intersecting site, allowing targeted air intake precisely where needed for cooling components, rather than requiring large-scale air circulation throughout the entire vehicle.
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
The design enhances support rigidity and cooling efficiency while reducing air resistance by securely fastening the duct and optimizing airflow, ensuring effective cooling of critical components without increasing weight or complexity.
Implementation Method 1
an outside air intake duct that takes in air flowing at the outside of the vehicle body and guides the air to an inside of the vehicle body
Implementation Method 2
The duct holding portion includes a plurality of duct securing portions to secure the duct body. The duct securing portions are disposed so as to be positioned on both sides of the duct body nipping the duct body.
