Vehicle Ventilator Air Guide Sleeve for Full Vent Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilators face limitations in ventilation efficiency due to restricted opening angles of upper cover plates, leading to reduced exhaust performance.
Innovation Solution
A ventilator design that includes a housing assembly with a fan blade, a cover plate assembly, and an air guide sleeve that can be lifted or lowered to expose or cover the vent, utilizing a second drive device and a controller to manage airflow, enhancing ventilation volume and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper cover plate is rotated by a predetermined angle to expose the vent, then the vent can be exposed, but the opening angle is limited resulting in smaller ventilation amount and low exhaust efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the cover plate movable between a closed state (covering the vent) and an open state (exposing the vent). This dynamic structure allows the cover plate to rotate or slide, enabling full exposure of the vent when needed, thereby maximizing ventilation amount and exhaust efficiency while maintaining ease of operation.
2Ease of operation
If the upper cover plate is rotated to expose the vent, then the vent becomes accessible, but the restricted opening angle reduces the ventilation volume
Solution Approach 1:
The dynamic cover plate design allows it to move from a closed position to a fully open position, maximizing the vent opening area. This ensures that when the vent needs to be accessed, the full ventilation volume is available, resolving the contradiction between accessibility and ventilation quantity.
Solution Approach 2:
The patent may employ a sliding or telescopic mechanism that extends the cover plate's movement beyond simple rotation, utilizing linear or multi-dimensional motion to achieve complete vent exposure. This dimensional approach allows the cover plate to clear the vent entirely, maximizing opening area and ventilation volume.
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
The design achieves high exhaust efficiency and superior exhaust performance by minimizing the impact of vent exposure on ventilation volume, allowing for better air exchange between the interior and exterior of a vehicle.
Implementation Method 1
The second drive device includes a lifting motor and a screw rod. The air guide sleeve is fixedly provided with a nut. The lifting motor is provided in the second accommodating space and configured to drive the screw rod to rotate. The nut is screwed with the screw rod to drive the nut to move in an extending direction of the screw rod when the screw rod rotates.
