Saddle-ride Vehicle Side Cover Airflow and Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-ride type vehicles face challenges in airflow regulation due to side cover sections that block airflow and accumulate heat, as existing designs either increase air resistance or fail to efficiently remove heat from the engine area.
Innovation Solution
The design incorporates a side cover section with a first recessed portion extended rearwards from the front end, slanted surfaces that gradually separate from the vehicle center, and a fixation portion above the recessed area, allowing for increased surface area while preventing lateral bulging, enhancing airflow regulation without creating seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the side cover section is bulged laterally outwards to increase surface area for airflow regulation, then the airflow regulation effect is improved, but the air resistance increases
Solution Approach 1:
The side cover section extends in the longitudinal direction (front-to-rear dimension) rather than bulging laterally (width dimension). The first recessed portion creates a longitudinal extension that increases surface area for airflow regulation while maintaining a compact lateral profile, thus reducing air resistance while achieving the desired airflow control effect.
2Object-affected harmful factors
If the side cover section is extended laterally to protect rider's feet, then the protection effect is improved, but the air resistance increases
Solution Approach 1:
Instead of extending the side cover laterally (width direction) to protect rider's feet, the design extends it longitudinally (front-to-rear direction) through the first recessed portion. This longitudinal extension provides adequate foot protection while maintaining a compact lateral profile that reduces air resistance.
3Force
If the side cover section has a perpendicularly edged shape for compact design, then the lateral extension is minimized, but turbulence occurs behind the leg shield
Solution Approach 1:
The side cover section employs curved surfaces instead of perpendicularly edged shapes. The first recessed portion features smooth curved transitions that guide airflow continuously from front to rear, eliminating sharp edges that would cause turbulence. This curved design maintains compact lateral dimensions while ensuring smooth airflow and reducing turbulence behind the leg shield.
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 airflow regulation, reduces heat accumulation, and improves air flow from front to rear, achieving a balance between airflow efficiency and heat management.
Implementation Method 1
the air flowing from the front side of the vehicle body is blocked due to the structure of the side cover section
Implementation Method 2
turbulence occurs in the air behind the leg shield due to the perpendicularly edged shapes of the rear end of the leg shield
Implementation Method 3
the surface area of the side cover section can be increased while the side cover section can be inhibited from being bulged laterally outwards from the vehicle body
Implementation Method 4
heat tends to be accumulated rearwards of the side cover section in the saddle-ride type vehicles especially when an engine is disposed below the seat

AI summary
A vehicle body cover of a saddle-ride type vehicle includes a top cover section (31), a side cover section (32) and a front cover section (34). The top cover section (31) forms a downwardly recessed vehicle body outline between the steering unit (6) and the seat (7) in a side view of the vehicle. The side cover section (32), covering a lateral side of a front fork (24), is fixed to the main frame (22) while being disposed from a position forward of the steering unit (6) to a position below the top cover section (31). The front cover section (34) is coupled to the top portion of the side cover section (32). The side cover section (32) includes a first recessed portion (41) extended rearwards from the front end of the side cover section (32). A top fixation portion (76), fixing the front cover section (34) and the side cover section (32), is disposed above the first recessed portion (41).
