Spoiler Lip Module With Adaptor For Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air guiding devices for motor vehicles have a complex and cumbersome process for replacing the spoiler lip when it is damaged, as it is directly attached to the front panel, leading to difficulties in maintenance and replacement.
Innovation Solution
The air guiding device features a spoiler lip mounted on an adaptor connected via a fastening device, allowing for indirect attachment to the front panel, enabling secure connection and easy replacement of the spoiler lip module, which includes an actuator, fastening device, and adaptor, with preassembly and testing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spoiler lip is directly attached to the front panel, then the connection is secure and stable, but the replacement process becomes complex and time-consuming
Solution Approach 1:
The air guiding device is segmented into a spoiler lip component and a mounting component that remains attached to the front panel. This allows the spoiler lip to be easily replaced by detaching only the specific component needing repair, while the mounting structure stays in place, significantly reducing replacement complexity while maintaining connection stability.
Solution Approach 2:
A mounting component serves as an intermediary element between the front panel and the spoiler lip. This mediator allows for secure attachment of the spoiler lip to the front panel while enabling easy detachment and replacement. The mounting component absorbs the complexity of the connection mechanism, leaving the spoiler lip itself simple to replace.
2Device complexity
If the spoiler lip is directly attached to the front panel, then the structure is simple, but the replacement process is time-consuming and complex
Solution Approach 1:
By dividing the air guiding device into separable components (spoiler lip and mounting structure), the overall structure remains relatively simple while enabling rapid replacement. The mounting component stays integrated with the front panel, but the spoiler lip can be quickly detached and replaced without complex disassembly procedures.
Solution Approach 2:
The mounting component is pre-installed and securely attached to the front panel before the spoiler lip is attached to it. This preliminary action creates a ready-made mounting structure that allows the spoiler lip to be quickly replaced without requiring re-attachment to the front panel each time, significantly reducing replacement time.
3Device complexity
If the spoiler lip is directly attached to the front panel, then fewer components are needed, but damage requires complete replacement of the assembly
Solution Approach 1:
The air guiding device is divided into a permanent mounting component and a replaceable spoiler lip component. This segmentation allows only the damaged spoiler lip to be replaced rather than the entire assembly, reducing the scope of replacement needed while adding only one additional component (the mounting structure).
Solution Approach 2:
The mounting component is extracted from the spoiler lip and integrated into the front panel structure. This extraction allows the spoiler lip to be independently replaced without removing the mounting structure, enabling partial replacement rather than complete assembly replacement, thus improving ease of repair with minimal additional complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the replacement process of the spoiler lip, providing enhanced rigidity and secure attachment, allowing for rapid and reliable installation of the air guiding device as a module, while maintaining aerodynamic functionality.
Implementation Method 1
The elastomer of the pneumatic actuators is deformed elastically during the filling operation and builds up a restoring force that returns the spoiler lip toward the rest position during the emptying operation.
Implementation Method 2
An actuating device moves the spoiler lip between a retracted rest position and an extended maximum position. The actuating device is a flexible, inflatable tube that can be filled or emptied to transfer the spoiler lip into different positions.
Implementation Method 3
The adaptor and the spoiler lip preferably have magnets that help hold the spoiler lip on the adaptor in the retracted rest position.
