Transparent Plastering Strip with Drip Edge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plaster strips for building edges, particularly those with thermal insulation, face issues such as visible drip strips that contrast with the plaster color, become dirty or yellowed due to UV exposure, and require separate production for different plaster colors, leading to aesthetic and logistical challenges.
Innovation Solution
A plaster strip design featuring a transparent drip strip with a plaster receiving area on one side, allowing the plaster color to shine through, thus minimizing UV exposure and dirt accumulation, and enabling a single strip to match various plaster colors, with optional oblique and tapered designs for improved aesthetics and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent drip edge is used, then the visibility of the drip edge is reduced, but the transparent part is exposed to UV radiation and becomes yellowed or soiled over time
Solution Approach 1:
The drip edge is divided into two distinct parts: a transparent section that allows plaster color to show through (reducing visibility), and a covered section that is protected from UV radiation. This segmentation allows each part to serve its specific function while mitigating the harmful effects of UV exposure on the transparent portion.
Solution Approach 2:
The plaster layer itself acts as an intermediary protective layer between the UV radiation and the transparent drip edge. By applying plaster over the transparent section, the plaster serves as a shield that blocks UV radiation while still allowing the color to show through the transparent material, thus protecting the drip edge from yellowing and soiling.
2Ease of manufacture
If a white drip edge profile is used, then the manufacturing is simple, but it contrasts with darker plaster colors and accumulates dirt
Solution Approach 1:
Instead of using a fixed white color for the drip edge, the invention uses a transparent material that allows the plaster color to show through. This color adaptation approach enables the drip edge to match any plaster color automatically, eliminating the need for multiple colored profiles while maintaining aesthetic appearance and reducing dirt visibility.
3Illumination intensity
If different plastering bead types are manufactured for different plaster colors, then the aesthetic appearance is improved, but the production and storage complexity increases
Solution Approach 1:
A single transparent plastering bead profile is designed to work with multiple plaster colors. The transparency of the material allows it to serve as a universal component that adapts to any plaster color, eliminating the need to manufacture and store multiple colored variants while maintaining aesthetic appearance across different applications.

AI summary
The invention relates to a plastering strip (10) suitable for installation on a building edge (20) having, for example, thermal insulation (21), with at least one plastering leg (11, 12) and a drip edge (13) projecting from the plastering leg (11, 12), wherein the drip edge (13) is at least largely transparent. According to the invention, the transparent part of the drip edge (13) has a plaster receiving area (14) on one side, so that when the plastering strip (10) is installed, the color of a plaster layer (23) shines through to the opposite, visible side (15) of the transparent drip edge (13).
