Structured Surface Carrier Material for Plaster-Like Interior Finishes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating a structured plaster-like surface on interior building surfaces are either expensive, require skilled workmanship, and result in a random appearance, unlike the natural look of structured plaster.
Innovation Solution
A method using a carrier material with a surface structure, applied like wallpaper, where the graining is bound with a low-viscosity binder that dissolves upon moisture, allowing the graining to be aligned and creating a plaster-like appearance, which can be achieved by using natural rocks or perlite, and optionally additives like methyl cellulose or dispersible polymer powders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If structured plastering is performed manually with thorny boards to create random appearance, then aesthetic quality is improved, but labor cost and skill requirement increase significantly
Solution Approach 1:
The surface structure is pre-formed on the carrier material before application to the building surface. The carrier material is provided with a surface structure that resembles structured plaster, allowing it to be manufactured in advance with consistent quality and then simply applied to the building surface like wallpaper.
Solution Approach 2:
The invention creates a copy of the desired structured plaster appearance on the carrier material. Instead of manually creating the structure on-site, the carrier material is pre-formed to replicate the aesthetic qualities of structured plaster, enabling easy application without requiring skilled workmanship.
2Ease of operation
If carrier material with surface structure is applied like wallpaper, then application ease is improved, but achieving natural plaster appearance becomes difficult
Solution Approach 1:
The carrier material is pre-formed with a surface structure that mimics structured plaster before being applied to the building surface. This preliminary structuring allows the material to be applied easily like wallpaper while maintaining the desired aesthetic appearance.
Solution Approach 2:
The surface structure on the carrier material is designed with specific parameters (grain size, texture, pattern) that change to match the appearance of structured plaster. The carrier material can be manufactured with varying surface characteristics to achieve different plaster-like effects.
3Stability of the object's composition
If graining is bound with strong binder, then structural stability is improved, but graining cannot be aligned properly after application
Solution Approach 1:
The binder is designed to change its properties dynamically - initially providing weak binding that allows graining alignment, then strengthening to provide stable retention. The binder may start with low viscosity for easy alignment, then cure or set to provide strong retention of the aligned graining structure.
Solution Approach 2:
The binding process occurs in stages or periods - first allowing free alignment of graining, then progressively increasing binding strength to lock in the aligned structure. This periodic action enables both alignment and retention requirements to be met at different times in the application process.
