Dual Support-Frame Air Shutter for Independent Front-End Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle shutter systems face challenges in independently controlling flaps on multiple support frames, complicating installation and connection, and often require a single actuator for both frames, limiting airflow optimization and aerodynamic efficiency.
Innovation Solution
A sealing device with two support frames, each having dedicated drive devices and flaps, where the frames are mechanically fixed to each other, allowing independent control and simplified installation, with complementary shapes and fastening mechanisms for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single actuator is used to rotate flaps on both support frames, then device complexity is reduced, but independent control capability is lost
Solution Approach 1:
The patent divides the actuation system into separate dedicated actuators for each support frame. The first actuator is exclusively coupled to the first support frame, and the second actuator is exclusively coupled to the second support frame. This segmentation enables independent control of each frame's flaps while maintaining manageable system complexity through modular architecture.
2Ease of manufacture
If support frames are made independent of each other, then ease of installation is improved, but structural stability deteriorates
Solution Approach 1:
The patent merges the first and second support frames into a single integrated assembly. The frames are positioned adjacent to each other with their respective actuators and flaps, forming a unified shutter system that provides both installation flexibility and structural stability through their combined configuration.
3Adaptability or versatility
If dedicated drive devices are provided for each support frame, then airflow optimization capability is improved, but device complexity increases
Solution Approach 1:
The patent implements local quality by providing specialized drive devices positioned at specific locations for each support frame. The first drive device is associated with the first support frame and the second drive device with the second support frame, allowing each frame to be independently optimized for its specific airflow control requirements without affecting the other.
