Saddle Vehicle Airflow Rectification for Engine Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle type vehicles face limitations in cooling performance due to restricted airflow into the engine cover, and positioning electrical components in front of the engine can disrupt airflow to the engine, potentially leading to inefficient cooling of both components.
Innovation Solution
The vehicle design includes an electrical component placed in front of the engine with a rectification member that guides traveling air to both the engine and the electrical component, utilizing space efficiently and ensuring precise airflow, while a separate rectification member with an attachment portion and positioning unit maintains accurate positioning and suppresses heat transmission between components.

Engineering Contradiction Analysis
1Volume of moving object
If the electrical component is disposed in front of the engine to utilize space efficiently, then the space utilization is improved, but the airflow path to the engine may be blocked
Solution Approach 1:
The rectification member extends in the vehicle widthwise direction (lateral dimension) with rectifying plates positioned at different widthwise locations. This dimensional arrangement allows air to flow laterally around the electrical component and be redirected to the engine, transforming a potential blockage problem into an efficient three-dimensional airflow pattern
