Textured Painting Roller for Fast Irregular Wall Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing painting techniques, such as spray, dabbed, and scratch effect painting, are time-consuming, require skill, and do not allow for quick and easy creation of patterned designs with aesthetic effects.
Innovation Solution
A painting device with a specially designed roller featuring orthogonal ribs that compress and remove paint to create an irregular streaked pattern, allowing inexperienced users to achieve a textured, attractive finish by rolling over fresh paint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spray painting is used to apply paint uniformly on the wall, then painting speed and paint consumption are improved, but the ability to create aesthetic effects and textured patterns deteriorates
Solution Approach 1:
The patent introduces a textured roller as an intermediary tool between the spray painting system and the wall surface. The roller's surface contains embossed patterns that transfer texture to the freshly sprayed paint, creating aesthetic effects without requiring direct contact or manual manipulation. This mediator enables pattern creation while maintaining the efficiency of spray painting.
2Ease of manufacture
If dabbed painting with a sponge pad is used to create a rippled effect, then original aesthetic results and customizable decoration are achieved, but painting time increases significantly
Solution Approach 1:
The roller's textured pattern is pre-formed and permanently embossed into its surface structure. When the roller contacts the freshly sprayed paint, the pattern is immediately transferred without requiring the user to manually dab or manipulate a sponge pad. This preliminary preparation of the texture pattern enables rapid application of aesthetic effects.
3Ease of manufacture
If spatula painting is used to create three-dimensional visual effects, then decorative impact is improved, but execution time and skill requirement increase
Solution Approach 1:
The textured roller serves as a mediator that automatically imparts three-dimensional texture patterns to the paint surface. The embossed designs on the roller transfer the decorative effect without requiring the operator to manually create overlapping lines and glazes with a spatula. This eliminates the need for extensive skill while maintaining the aesthetic impact.
4Ease of manufacture
If scratch effect painting with a metal trowel is used to create defined lines, then durability and customization are improved, but painting time and skill requirement increase
Solution Approach 1:
The roller contains pre-formed linear and geometric patterns embossed into its surface. As the roller moves across the freshly sprayed paint, these pre-configured designs are automatically transferred, creating defined lines and geometric patterns without requiring the operator to manually scratch or drag a trowel. This preliminary patterning enables rapid execution of durable, customized designs.

AI summary
A painting device (100) comprises: a handle (1), a support rod (2) and a roller (6) rotatably mounted on the support rod (2); the roller (6) comprising a lateral surface (40) and a plurality of ribs (51, 52), namely longitudinal ribs (51) distributed along rows (R) and transverse ribs (52) distributed along circumferential columns (C); the roller (6) being suitable for rolling over a layer of fresh paint applied to a surface of a wall or substrate, so that the ribs (51, 52) compress the fresh paint leaving imprints (7) of irregular contour with a different shade of color than a color (8) of the layer of fresh paint that has not been in contact with said ribs (51, 52) of the roller, so that the surface repeatedly paints the same pattern with a texture comprising a shaded irregular set of orthogonal streaks.
