Removable Air Duct for Off-Road Vehicle Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side-by-side all-terrain vehicles often experience insufficient airflow into the passenger area, leading to discomfort during warm weather, as most glass windshields do not have vents, prompting drivers or passengers to remove the windshield for cooling, which compromises safety.
Innovation Solution
A ventilation system featuring an air duct that can selectively attach to and detach from the vehicle's rollover protection system, redirecting external air into the passenger area without removing the windshield, utilizing an attachment member that allows for non-destructive and tool-free installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the windshield is removed to increase cooling airflow into the passenger area, then the airflow volume increases, but the vehicle safety and structural integrity deteriorate
Solution Approach 1:
The windshield assembly is segmented into multiple components: the main windshield structure and a separate removable air duct component. This allows the air duct to be detached for increased airflow while the main windshield remains in place to maintain safety and structural integrity.
Solution Approach 2:
A removable air duct acts as an intermediary component between the external environment and the passenger area. It provides an additional airflow pathway when attached, and can be removed when maximum airflow is needed, without requiring removal of the main windshield structure.
2Temperature
If the windshield is removed to provide cooling air, then the cooling effectiveness improves, but the ease of operation and convenience deteriorate due to repeated installation and removal
Solution Approach 1:
The air duct is designed with dynamic attachment and detachment capabilities, allowing it to be easily installed and removed from the windshield frame. This dynamic design enables users to adjust the configuration based on cooling needs without complex tools or procedures.
3Quantity of substance
If a fixed air duct is installed to increase airflow, then the cooling performance improves, but the adaptability and versatility deteriorate
Solution Approach 1:
The ventilation system is divided into a permanent windshield structure and a separate, removable air duct component. This segmentation allows the air duct to be attached when increased airflow is needed and removed when not needed, providing adaptability while maintaining the option for enhanced cooling performance.
Solution Approach 2:
The air duct component serves multiple functions: it can be attached to increase airflow when needed, removed when maximum cooling is required, and stored when not in use. This multi-functionality provides versatility while maintaining the ability to improve airflow rate when the duct is attached.
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
Enhances airflow into the vehicle's passenger area, maintaining the integrity of the windshield while providing cooling air, thus improving passenger comfort without compromising safety or requiring windshield removal.
Implementation Method 1
The air duct can be configured to receive air along the first direction and redirect air flowing to the air duct to exit the air duct in the second direction such that air outside the vehicle enters the vehicle
