Two-Piece Automotive Splash Guard Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional manufacturing process for two-tone painted automotive components, such as splash guards, is cumbersome and wasteful, involving high labor costs and material expenses due to the need for hand-applied self-adhesive masking and resulting in increased scrap from the painting process.
Innovation Solution
The method involves molding two separate pieces for the splash guard, where one piece is painted separately and then mechanically joined or adhered to the other, eliminating the need for a separate paint masking process by using a two-piece, two-color design with one piece painted and the other in a natural black material, allowing for a clean transition between colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional masking process is used to manufacture two-tone painted parts, then a clean transition line between painted and non-painted sections can be achieved, but labor costs and material costs increase significantly
Solution Approach 1:
The component is divided into two separate pieces: a painted portion and a non-painted portion. Each piece is manufactured independently, eliminating the need for masking during painting. The pieces are then joined together to form the final two-tone component, achieving clean color transitions without the complexity of traditional masking processes.
2Manufacturing precision
If hand-applied self-adhesive masking is used, then a defined line between painted and non-painted sections is achieved, but material costs and scrap increase
Solution Approach 1:
The component is divided into two separate pieces: a painted portion and a non-painted portion. Each piece is manufactured independently, eliminating the need for masking during painting. The pieces are then joined together to form the final two-tone component, achieving clean color transitions without the complexity of traditional masking processes.
3Manufacturing precision
If traditional masking process is used, then two-tone painted parts can be manufactured, but productivity decreases due to cumbersome process steps
Solution Approach 1:
The component is divided into two separate pieces: a painted portion and a non-painted portion. Each piece is manufactured independently, eliminating the need for masking during painting. The pieces are then joined together to form the final two-tone component, achieving clean color transitions without the complexity of traditional masking processes.
Solution Approach 2:
The component is divided into two separate pieces: a painted portion and a non-painted portion. Each piece is manufactured independently, eliminating the need for masking during painting. The pieces are then joined together to form the final two-tone component, achieving clean color transitions without the complexity of traditional masking processes.

AI summary
An automotive splash guard includes first and second molded pieces. The first molded piece has a shape configured to have at least a portion thereof installed outside an automobile wheel well, and the second molded piece has a shape configured to be installed in an automobile wheel well. The first piece has an exterior painted surface, the first piece is separate from the second piece while the first piece is being painted and is attached to the second piece after being painted by mechanical joining or adhering. A method for manufacturing a splash guard includes molding the first piece; molding the second piece; painting the first piece while it is separate from the second piece; and then attaching the second piece to the first piece.
