Quick-Release Air Dam for Variable Ground Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air dams for vehicles lack a convenient and efficient mechanism to quickly transition between deployed and stowed positions, which limits their adaptability for different driving conditions such as highway driving and off-roading, where varying ground clearance is necessary.
Innovation Solution
The air dam assembly incorporates a quick-release pin system that secures the air dam to the vehicle structure, allowing it to be easily transitioned between deployed and stowed positions without requiring rotation, using spring-biased retaining members and a pull ring mechanism to facilitate movement along a longitudinal axis, enabling the air dam to be raised and lowered by an actuator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional securement mechanism is used for the air dam, then the air dam remains fixed in position, but the ability to quickly transition between deployed and stowed positions is limited
Solution Approach 1:
The securement mechanism is segmented into multiple quick-release pins distributed at different locations on the air dam. Each pin can be independently operated to release specific sections of the air dam, allowing for controlled transition between positions while maintaining overall structural integrity during operation.
Solution Approach 2:
The quick-release pin mechanism transforms the static securement system into a dynamic one where the air dam can rapidly transition between fixed (deployed) and movable (stowed) states. The pins allow the air dam to be quickly released and repositioned based on driving conditions, enabling adaptive ground clearance adjustment.
2Adaptability or versatility
If the air dam is kept in deployed position for highway driving, then airflow redirection is optimized, but ground clearance is reduced for off-roading
Solution Approach 1:
The air dam system is designed to be dynamic rather than static, allowing it to adapt its position based on driving conditions. The quick-release pins enable the air dam to be quickly transitioned between deployed (for highway airflow optimization) and stowed (for off-road ground clearance) positions, providing versatility across different terrains and speeds.
Solution Approach 2:
The air dam assembly serves multiple functions through its adjustable positioning capability. When deployed, it optimizes aerodynamic airflow for highway driving; when stowed, it provides increased ground clearance for off-road conditions. The universal design allows a single air dam structure to fulfill both aerodynamic and ground clearance requirements across diverse driving scenarios.
3Adaptability or versatility
If multiple apertures are provided in the vehicle structure for different positions, then the air dam can be secured at multiple positions, but the structure becomes more complex
Solution Approach 1:
The vehicle structure incorporates multiple discrete apertures positioned at different heights and locations to accommodate the air dam in various positions. Each aperture is a distinct opening that receives a corresponding quick-release pin, allowing the air dam to be secured at multiple predetermined positions (deployed, intermediate, stowed) while maintaining a relatively simple overall structural design.

AI summary
An air dam assembly includes, among other things, an air dam and at least one quick-release pin that secures the air dam to a vehicle structure. An air dam positioning method includes, among other things, when an air dam is in a first position, the step of coupling the air dam to a vehicle structure using at least one quick-release pin in an engaged position. The method further includes transitioning the at least one quick-release pin to a disengaged position, and then, when the quick-release pin is in the disengaged position, moving the air dam to a second position that is different than the first position. The method then, when the air dam is in the second position, includes coupling the air dam to the vehicle structure using the at least one quick-release pin.
