Vehicle Display Decorative Part Radial Concentric Groove Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display device decorative parts lack fresh visual effects, as they do not effectively combine patterns to enhance aesthetic appeal.
Innovation Solution
A vehicle display device decorative part featuring a first area with radially extending grooves and a second area with concentrically or spirally extending grooves, where the second grooves have a deeper maximum depth than the first grooves, creating a radial and spin pattern combination that enhances visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional resin-made board with single pattern is used, then the manufacturing process is simple, but the visual effects are not fresh or appealing
Solution Approach 1:
The decorative part is divided into multiple areas (first area with radially extending grooves, second area with concentrically/annularly extending grooves) each having distinct groove patterns. This segmentation allows different visual effects in different regions while maintaining a unified manufacturing process through mold transfer.
Solution Approach 2:
Different groove patterns (radial in first area, concentric/annular in second area) and different groove depths are applied to different areas of the decorative part. This local differentiation creates varied visual effects across the surface, enhancing overall aesthetic appeal while using a single molded component.
2Shape
If multiple groove patterns with different depths are created, then fresh visual effects are achieved, but the manufacturing complexity increases
Solution Approach 1:
The groove patterns are pre-formed on the molding surface of the mold before the resin material is injected. This preliminary action allows complex multi-pattern groove structures to be automatically transferred to the decorative part during a single molding process, avoiding post-manufacturing operations.
Solution Approach 2:
The groove patterns are transferred from the molding surface of the mold to the surface of the resin material through the molding process itself. This copying mechanism enables precise replication of complex groove patterns (radial, concentric, annular) with different depths without requiring separate manufacturing steps.
3Ease of manufacture
If grooves are transferred from mold surface, then manufacturing is simplified, but precision in groove depth and pattern must be maintained
Solution Approach 1:
The mechanical process of manually creating grooves on the decorative part surface is replaced by a molding process where grooves are automatically transferred from the mold surface to the resin material. This substitution ensures consistent groove depth and pattern through the inherent precision of the molding process.
Solution Approach 2:
The groove depth parameter is controlled by varying the depth of grooves formed on the molding surface of the mold. By adjusting this parameter during mold fabrication, precise control over the final groove depths in different areas (first area radial grooves, second area concentric/annular grooves) is achieved, ensuring manufacturing precision.

AI summary
A vehicle display device decorative part and a vehicle display device include a first area provided in the vehicle display device that displays information regarding a vehicle, and having a first pattern formed of a plurality of first grooves, and a second area provided to be included in the first area, and having a second pattern formed of a plurality of second grooves. As a result, the vehicle display device decorative part and the vehicle display device exhibits an effect to realize new and fresh visual effects due to a synergistic effect by a combination of the first pattern formed in the first area and the second pattern formed in the second area included in the first area.
