Modular Rear Spoiler with Removable Second Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rear spoilers on motor vehicles are difficult and expensive to change due to their permanent attachment, limiting customization and repair options, and complicating the manufacturing process.
Innovation Solution
A modular rear spoiler design featuring a first part attached to the vehicle and a second part that can be easily removed and replaced, allowing for varying geometry and appearance, with snap-fastening or nut and bolt attachments, and incorporating a reinforcement for structural integrity and aesthetic enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spoiler is permanently attached to the vehicle, then the structural integrity and aerodynamic performance are maintained, but the difficulty and cost of changing the spoiler increases
Solution Approach 1:
The spoiler is divided into two separate parts: a first part that remains permanently attached to the vehicle, and a second part that can be easily removed and replaced. This segmentation allows the permanent attachment to maintain structural integrity while enabling easy replacement of the removable second part.
2Reliability
If the spoiler is permanently attached to the vehicle, then the aerodynamic performance is maintained, but the cost of changing the spoiler increases
Solution Approach 1:
By segmenting the spoiler into permanent and removable parts, the invention allows customers to replace only the aesthetic second part rather than the entire spoiler assembly, significantly reducing replacement costs while maintaining aerodynamic performance through the permanent first part.
3Ease of manufacture
If the spoiler has a single-piece design, then the manufacturing process is simpler, but the ability to customize geometry and appearance is reduced
Solution Approach 1:
The two-part design enables different geometries and appearances to be created by combining the permanent first part with various removable second parts, significantly increasing customization options while keeping the manufacturing of each individual part relatively simple.
Solution Approach 2:
The invention applies different qualities to different parts: the first part maintains structural and aerodynamic qualities, while the second part provides aesthetic customization. This allows each part to be optimized for its specific function.
4Shape
If the second part covers the entire upper surface of the first part, then the aesthetic appearance is improved, but the visibility of the first part's surface features is reduced
Solution Approach 1:
The second part is designed to cover only specific portions of the first part's upper surface, allowing different regions to have different aesthetic treatments. This selective coverage maintains visibility of important surface features while improving overall aesthetic appearance.

AI summary
A rear spoiler of a motor vehicle. The spoiler includes a first part intended for being attached to the rear of the vehicle in an attachment position by a first attachment means, and a second part which is intended for being removably attached to the first part in an attachment position by a second attachment means, the second part leaving a portion of the upper surface of the first part visible in this attachment position.
