Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulation systems face issues with thermal insulation materials having low mechanical strength and poor hygrothermal properties, leading to irreversible deformations and cracking, which compromise both thermal and sound insulation performance.
Innovation Solution
A two-component plastering compound is used, comprising a pasty first component with both mineral and organic binders, and a further component to accelerate hardening, applied in thicker layers to form a reinforcing and/or plaster layer that enhances mechanical properties and flexibility, reducing the risk of cracking and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal insulation materials with excellent thermal insulation values are used, then thermal insulation performance is improved, but mechanical strength and dimensional stability deteriorate
Solution Approach 1:
The patent employs composite insulation elements combining phenolic resin foam core with polystyrene particle foam cover layers. This composite structure leverages the excellent thermal insulation properties of phenolic resin while the polystyrene cover layers provide enhanced mechanical strength and dimensional stability, resolving the contradiction between thermal performance and mechanical properties.
2Temperature
If insulation elements with low mechanical strength are used, then thermal insulation performance is improved, but dimensional stability deteriorates
Solution Approach 1:
The multi-layer composite structure with phenolic resin core and polystyrene cover layers provides both excellent thermal insulation and high dimensional stability. The cover layers constrain the phenolic resin core, preventing irreversible deformations and bowl-shaped distortions while maintaining thermal performance.
3Ease of operation
If plaster and reinforcement layers are applied in thin layers, then ease of application is improved, but ability to stop deformation of underlying insulation element deteriorates
Solution Approach 1:
The patent applies plaster and reinforcement layers in multiple sequential layers rather than a single thin layer. This multi-layer application method provides cumulative protective effect, with each layer contributing to stopping deformation of the insulation element while maintaining practical applicability. The progressive layering ensures sufficient thickness to counteract deformation without making application excessively difficult.
