Motorcycle Radiator Air Guide Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motorcycles, the high-temperature air discharged from the radiator directly impinges on the rider's feet, causing discomfort, especially in summer, due to the existing design that directs this air rearward from the side covers.
Innovation Solution
An air guide passage is created between the cover and the fuel tank to redirect high-temperature air to an area higher than the fuel tank, ensuring it flows rearward and mixes with a large quantity of running wind, thereby diluting its temperature to match the ambient wind temperature, preventing direct impingement on the rider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is discharged rearward from exhaust ports in side covers, then the radiator cooling function is achieved, but high temperature air directly impinges on rider's feet causing discomfort
Solution Approach 1:
The air guide passage redirects the discharge direction of hot air from horizontal (rearward at rider level) to vertical (upward above fuel tank), changing the spatial dimension of air flow. This dimensional change allows hot air to be discharged above the rider's foot level, eliminating direct impingement while maintaining cooling efficiency
Solution Approach 2:
The air guide passage acts as an intermediary structure between the radiator and the external environment. It intercepts hot air from the radiator, redirects it through a controlled path, and discharges it at a different location (above fuel tank), thereby mediating the harmful effect of hot air on the rider
2Device complexity
If air is discharged at rider level, then the structure is simple, but rider comfort deteriorates due to direct heat exposure
Solution Approach 1:
The air guide passage is nested within the existing motorcycle structure, utilizing the space between the cover and fuel tank. This nested configuration adds the air redirection function without requiring external additions, maintaining structural compactness while improving rider comfort
Solution Approach 2:
By changing the discharge dimension from horizontal to vertical, the invention achieves air redirection using the existing vertical space above the fuel tank, avoiding the need for complex external air discharge structures
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 solution effectively prevents rider discomfort by ensuring high-temperature air is diluted and discharged above the rider's foot level, maintaining a comfortable temperature and reducing heat-related issues.
Implementation Method 1
An air guide passage situated between the cover and the fuel tank guides air that has passed through the radiator to an area higher than the fuel tank
Implementation Method 2
high temperature air guided to this area is diluted with a large quantity of running wind to substantially the same temperature as that of the running wind
Data Source
AI summary
A motorcycle that discharges air that has passed through a radiator such that the air does not directly impinge on a rider, thereby resolving discomfort. An air guide passage guides air that has passed through the radiator so that the air passes through a gap between a front side cover and a fuel tank to a portion higher than the fuel tank.
