Reinforced Plaster Interior Elements for Seamless Crack-Resistant Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior decoration systems often develop cracks, splits, and apertures over time due to material property differences between construction elements and wall plastering, leading to a loss of seamless integration and aesthetic appeal, especially in modern and hygienic environments.
Innovation Solution
The use of reinforced wall plastering material for both the body and joining elements of interior decoration elements, such as glass-reinforced gypsum, ensures a strong bond with the wall plaster, reducing the risk of cracks and providing improved strength, rigidity, and impact resistance, allowing for seamless integration and easy production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If construction elements are mounted to walls before plastering and covered with plaster to achieve seamless integration, then aesthetic appearance is improved, but connection reliability deteriorates over time causing cracks and splits
Solution Approach 1:
The construction element is made from the same reinforced wall plastering material as the wall plaster itself, creating material homogeneity. This ensures both elements expand and contract uniformly with temperature and humidity changes, preventing differential movement that causes cracks and maintains seamless integration over time.
Solution Approach 2:
The invention uses reinforced wall plastering material containing fibrous reinforcement (such as glass fibers) that provides both the seamless aesthetic quality and enhanced mechanical strength. The composite structure with distributed fibers prevents crack propagation and maintains connection reliability while achieving the desired seamless appearance.
2Ease of manufacture
If conventional materials are used for construction elements, then ease of manufacture is maintained, but bond strength with wall plaster deteriorates leading to cracks
Solution Approach 1:
Using the same reinforced plastering material for both the construction element and wall plaster eliminates material incompatibility issues. The homogeneous material composition ensures strong chemical and mechanical bonding while maintaining ease of manufacture through standardized production processes for reinforced plaster products.
Solution Approach 2:
The invention changes the material parameters by incorporating fibrous reinforcement into the plastering material, transforming it from a brittle conventional plaster to a toughened composite material. This parameter change enhances bond strength and crack resistance while the material remains processable using standard plastering manufacturing techniques.
3Adaptability or versatility
If construction elements are made from materials different from wall plaster, then manufacturing versatility is improved, but material compatibility deteriorates causing differential expansion and cracking
Solution Approach 1:
The construction element is manufactured from the same reinforced wall plastering material as the wall, ensuring homogeneous composition and compatible thermal-hygrometric behavior. This eliminates differential expansion and contraction that would otherwise cause cracking at the interface between different materials.
4Strength
If reinforced wall plastering material is used for construction elements, then bond strength and crack resistance are improved, but weight of the element increases
Solution Approach 1:
The reinforced plastering material uses lightweight fibrous reinforcements (such as glass fibers) dispersed in the plaster matrix. These fibers provide significant strength and crack resistance improvements while adding minimal weight compared to conventional solid materials, achieving high strength-to-weight ratio.
