Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear spoiler systems for commercial vehicles are complex, limited in adjustability, and often interfere with the operation of rear doors, leading to increased air resistance and reduced accessibility due to complex connections and limited air guiding element lengths.
Innovation Solution
A rear spoiler device with adjustable air guiding elements that seal against the vehicle's outer surfaces using a sealing means, such as a sealing lip, and a four-bar linkage mechanism for easy adjustment between rest and driving positions, allowing for reduced air resistance by eliminating turbulence and vortex formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air guiding elements are connected to the hinge area of rear doors, then aerodynamic optimization is achieved, but the pivoting process is impaired and device complexity increases
Solution Approach 1:
The air guiding element is extracted from the hinge connection and instead connected to the rear door's outer surface. This allows the air guiding element to be adjusted independently without interfering with the hinge pivoting mechanism, resolving the contradiction between aerodynamic optimization and ease of door operation.
Solution Approach 2:
The air guiding element is designed to be adjustable between different positions (retracted and extended) relative to the rear door. This dynamic configuration allows the system to optimize aerodynamics when needed while maintaining full door accessibility when the air guiding element is retracted.
2Reliability
If complex locking mechanisms are provided to ensure stability of air currents, then aerodynamic stability is improved, but device complexity and difficulty of adjustment increase
Solution Approach 1:
The air guiding element utilizes the aerodynamic forces generated during vehicle operation to automatically maintain its extended position and ensure stability of air currents. The design eliminates the need for complex locking mechanisms by allowing the air guiding element to self-stabilize through the very air flows it is designed to manage.
3Object-affected harmful factors
If air guiding elements are extended to cover irregularities on the vehicle surface, then aerodynamic performance is improved, but the length of air guiding elements is limited by hinge configurations
Solution Approach 1:
By extracting the air guiding element from the hinge connection, the patent removes the constraint that limited the length of air guiding elements. This allows the air guiding element to be extended sufficiently to cover irregularities on the vehicle surface and effectively reduce turbulence and vortex formation without being constrained by hinge configuration.
4Loss of energy
If rear spoiler systems are designed to improve aerodynamics, then fuel consumption is reduced, but accessibility and ease of adjustment are reduced
Solution Approach 1:
The air guiding element is designed with adjustable positioning capability, allowing it to be extended or retracted as needed. This dynamic adjustment feature maintains aerodynamic performance when extended while preserving full accessibility and ease of operation when retracted, resolving the contradiction between energy efficiency and ease of adjustment.
