Front-End Air Intake Flap Frames for Independent Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle shut-off devices for air intakes often have difficulty in independently controlling multiple support frames, complicating mounting and connection, and lack optimal aerodynamic control.
Innovation Solution
A device comprising two support frames with complementary fixing sidewalls and dedicated drive devices for each frame, allowing independent control of flaps and improved aerodynamic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single actuator is used to pivot flaps of multiple support frames, then device complexity is reduced, but independent control capability is lost
Solution Approach 1:
The patent divides the actuation system into separate segments, with each support frame having its own dedicated actuator. This segmentation enables independent control of each flap while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The system transitions from a static, unified actuation mechanism to a dynamic, distributed control system where each actuator can independently adjust its corresponding flap based on real-time requirements, enabling adaptive air flow control.
2Adaptability or versatility
If multiple independent support frames are used, then independent control capability is improved, but mounting and connection complexity increases
Solution Approach 1:
The support frames are designed with universal mounting features and standardized connection interfaces that can be used across different frames, enabling independent control capability while simplifying mounting and connection procedures through reusable components.
Solution Approach 2:
The patent combines multiple support frames into a integrated assembly where frames are mechanically connected through standardized interfaces, allowing independent control of each frame while reducing overall mounting complexity through unified installation procedures.
3Adaptability or versatility
If support frames are made independent of one another, then adaptability is improved, but structural stability decreases
Solution Approach 1:
The support frame system is segmented into independent, modular units that can be configured flexibly while maintaining structural integrity through standardized connection points and reinforcement features designed into each segment.
Solution Approach 2:
The support frames are designed with nested or interlocking features where frames can be independently positioned yet structurally supported by the overall assembly, allowing configuration flexibility while maintaining structural stability through hierarchical support relationships.
