Movable Spoiler Gap Cover Mechanism for Aerodynamic Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable spoiler devices suffer from gaps during movement, leading to foreign matter intrusion and reduced aerodynamic performance due to the relative motion of the movable and fixed parts.
Innovation Solution
A movable spoiler device with a cover member linked to the movable part that covers the gap formed between the movable and fixed parts during movement, using a rotatable mechanism to adaptively fill the gap and prevent foreign matter intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the movable part moves relative to the fixed part to adjust aerodynamic performance, then the aerodynamic performance is improved, but a gap is formed between the movable part and fixed part allowing foreign matter intrusion
Solution Approach 1:
A cover member is introduced as an intermediary element between the movable part and the external environment. The cover member moves synchronously with the movable part through a link mechanism, continuously covering the gap that forms during movement, thereby preventing foreign matter intrusion while allowing aerodynamic adjustment
2Adaptability or versatility
If the movable part moves relative to the fixed part to adjust aerodynamic performance, then the aerodynamic performance is improved, but aerodynamic performance is reduced due to the gap formation
Solution Approach 1:
The cover member acts as a mediator that maintains aerodynamic continuity by covering the gap formed during movable part movement. By synchronously following the movable part's position changes, the cover member prevents airflow disruption and energy loss that would otherwise occur through the gap
Solution Approach 2:
The cover member is designed to dynamically adjust its position in synchrony with the movable part through the link mechanism. This dynamic coverage ensures that the gap is continuously sealed during movement, maintaining optimal aerodynamic performance across different positions

AI summary
A movable spoiler device is provided in the disclosure. The movable spoiler device includes: a fixed part, fixed on a body of a vehicle; a movable part, configured to be movable between a storage position connected to the fixed part and a deployed position protruding from the fixed part toward rear of the vehicle; an actuator, disposed on the fixed part and drives the movable part to move in a front-rear direction of the vehicle; and a cover member, disposed on the fixed part and connected to the movable part so as to be linked with the movable part, in which there is a gap between the movable part and the fixed part due to the movement of the movable part, when the movable part moves from the storage position to the deployed position, the cover member is driven by the movable part to move and cover the gap.
