Vehicle Spoiler Positioning Wedge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Achieving a consistent and flush adjustment between the rear spoiler and the rear end of a motor vehicle roof is complex, making it difficult to attain a high-quality finish on the assembly line.
Innovation Solution
A device comprising a fixed wedge and an adjustable wedge with pre-holding notches and flexible blades, allowing for precise adjustment and locking of the spoiler's position relative to the roof, using a template to set dimensional characteristics and ensuring a flush fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional adjustment methods are used for spoiler positioning, then the adjustment process becomes complex and time-consuming, but achieving consistent flushness between the spoiler and roof remains difficult
Solution Approach 1:
The adjustment device is segmented into two independent wedges: a fixed wedge attached to the vehicle body and an adjustable wedge attached to the spoiler. This segmentation allows the adjustable wedge to be independently positioned and adjusted without affecting the fixed wedge, enabling precise flushness control while simplifying the overall adjustment process.
Solution Approach 2:
The adjustable wedge acts as an intermediary element between the fixed wedge and the spoiler. By positioning the adjustable wedge between these two components, it mediates the geometric dispersions and enables precise positioning of the spoiler relative to the roof, achieving consistent flushness while maintaining a simple adjustment mechanism.
2Productivity
If manual adjustment methods are used for spoiler positioning, then flexibility is maintained, but the adjustment process becomes time-consuming and difficult to reproduce on an assembly line
Solution Approach 1:
The fixed wedge is pre-positioned and fixed to the vehicle body at the correct location before spoiler installation. The adjustable wedge is pre-configured with notches at predetermined positions. This preliminary preparation eliminates the need for complex measurements and adjustments during assembly, enabling rapid and reproducible spoiler positioning on the assembly line.
Solution Approach 2:
The adjustable wedge functions as a temporary, disposable adjustment element. It is used during assembly to achieve the correct spoiler position, then locked in place. This simple, inexpensive component enables rapid adjustment without requiring complex, time-consuming manual procedures, significantly improving assembly line productivity.
3Manufacturing precision
If the spoiler is fixed directly to the vehicle body, then the structure is simplified, but geometric dispersions prevent achieving desired flushness and clearances
Solution Approach 1:
The mounting structure transitions from a static direct fixation to a dynamic adjustable system. The adjustable wedge can be positioned at different notches to compensate for geometric dispersions in the vehicle body and spoiler components. This dynamic adjustment capability enables precise control of flushness and clearances while maintaining a relatively simple mounting structure consisting of only two wedges and a locking mechanism.
