Dual Vehicle Flap Control With Sequential Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems of controlled flaps for vehicles cannot independently control the opening and closing of two sets of flaps, limiting flexibility and efficiency in air management.
Innovation Solution
A system with two sets of flaps, each driven by an actuator, utilizing a spring, upper and lower levers with lost motion cams, and connecting rods to allow independent control of flap positions, enabling a modular flap control strategy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two sets of flaps are controlled simultaneously to open or close, then the structure is simple, but one set of flaps cannot be opened or closed independently of the other
Solution Approach 1:
The single actuator is segmented into two independent output mechanisms: a first output mechanism connected to the first set of flaps and a second output mechanism connected to the second set of flaps. This segmentation allows each set of flaps to be controlled independently while using a single actuator, resolving the contradiction between independent control capability and device complexity.
2Ease of operation
If a single actuator drives both sets of flaps, then the number of actuators is reduced, but independent control of each flap set is limited
Solution Approach 1:
The single actuator is designed with multi-functionality, serving as both a first actuator for the first set of flaps and a second actuator for the second set of flaps. The actuator includes a first output mechanism and a second output mechanism that can independently drive respective flap sets, enabling flexible control operations while reducing the total number of actuators required.
3Adaptability or versatility
If flaps are opened simultaneously, then the control system is simple, but air management flexibility under the engine hood is reduced
Solution Approach 1:
The control system implements dynamic operation where the first set of flaps and the second set of flaps can be opened or closed in different sequences and at different rates. The actuator can independently adjust the position of each flap set based on operating conditions, providing dynamic air management flexibility while maintaining a relatively simple control architecture.
