Rear Spoiler Airflow Rectification and Armrest Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle-type vehicles with rear spoilers are susceptible to airflow turbulence near the rear cover, affecting their air-rectifying capabilities and passenger comfort.
Innovation Solution
The rear spoiler is designed with an inclined arm-resting surface covered by a cushioned member, retained above the seat by a hollow pillar-shaped retainer section, which positions the spoiler sections above the seat to avoid turbulent airflow and provides an arm-resting function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rear spoiler is arranged in the immediate vicinity of the rear cover, then the structure is compact and simple, but the spoiler is susceptible to turbulent airflow from the rear cover surface
Solution Approach 1:
The rear spoiler is repositioned from a horizontal arrangement near the rear cover to a vertical arrangement above the seat. This dimensional change in spatial positioning moves the spoiler out of the turbulent airflow zone generated by the rear cover surface, eliminating airflow interference while maintaining structural compactness through the vertical retention mechanism
2Object-affected harmful factors
If the rear spoiler is positioned above the seat, then air rectification is effective without turbulence interference, but the structure becomes more complex
Solution Approach 1:
The hollow pillar-shaped retainer section serves multiple functions: it retains the spoiler sections above the seat, provides structural support, and acts as an air guide to direct airflow. This multi-functionality simplifies the overall structure by consolidating multiple components into a single integrated element, reducing the complexity that would otherwise result from positioning the spoiler above the seat
3Ease of operation
If the arm-resting surface is added to the spoiler section, then passenger comfort is improved, but the device complexity increases
Solution Approach 1:
The arm-resting surface is merged with the spoiler section, combining the air rectification function and the arm-resting function into a single integrated structure. The spoiler section simultaneously serves as an aerodynamic component and as a passenger comfort feature, eliminating the need for separate armrest components and reducing overall device complexity
