Removable Motor Vehicle Spoiler Bezel Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear spoilers in vehicles face limitations in geometry and length due to assembly constraints with the bezel, requiring additional assembly and disassembly operations, and often result in a visible upper edge of the bezel, affecting aesthetics and user perception.
Innovation Solution
A rear spoiler design featuring a first part permanently attached to the vehicle and a removable second part that covers the upper edge of the bezel, allowing for flexible assembly and disassembly of the rear window, and adjustable geometry by modifying the length of the spoiler's extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spoiler length is shortened to allow bezel positioning, then the assembly operation becomes feasible, but the spoiler geometry possibilities are limited and the upper edge of the bezel remains visible
Solution Approach 1:
The spoiler is divided into a first part that remains fixed during bezel assembly and a second part that is removable. This segmentation allows the bezel to be assembled on the tailgate without interference from the spoiler, while the removable second part can be temporarily removed to clear the assembly path and then reinstalled to cover the bezel edge.
Solution Approach 2:
The second part of the spoiler is made removable rather than fixed, allowing it to be temporarily removed during bezel assembly and then reinstalled. This dynamic approach enables the spoiler to adapt to the assembly process requirements while maintaining its full geometry and length possibilities.
2Reliability
If the spoiler is made non-removable or integrated with the tailgate, then the aerodynamic benefits are maintained, but additional assembly and disassembly operations are required
Solution Approach 1:
The spoiler is segmented into a first part that remains permanently attached to maintain aerodynamic performance and a second part that is removable. This allows the essential aerodynamic structure to remain fixed while only the non-critical second part is removed and reinstalled during bezel assembly.
Solution Approach 2:
The second part of the spoiler is extracted (removed) only when necessary for bezel assembly, while the first part remains in place to maintain aerodynamic performance. This selective removal minimizes the time loss associated with assembly operations.
3Ease of operation
If the second part is made removable to allow bezel assembly, then the upper edge of the bezel can be covered, but the spoiler structure becomes more complex
Solution Approach 1:
The spoiler is divided into two parts with the second part being removable. This segmentation enables the bezel to be assembled by temporarily removing the second part, then reinstalling it to cover the bezel edge, all while keeping the overall structure relatively simple.
Solution Approach 2:
The removable second part serves multiple functions: it allows bezel assembly by being temporarily removed, and it covers the upper edge of the bezel when installed, providing both operational flexibility and aesthetic coverage.

AI summary
The invention relates to a motor vehicle rear spoiler (1). This spoiler (1) is characterized in that it comprises - A first part (10) which is intended to be fastened in a position assembled on the rear of the vehicle and which forms the upper face of the spoiler (1), - A second part (20) which forms at least one part of the lower face of the spoiler (1) and which is able to cover an upper edge (985) of a rear window (98) of the vehicle when this second part (20) is in the assembled position, the second part (20) being removable so as to allow a rear window (98) to be assembled on or disassembled from this vehicle.
