Solution Overview

Problem

Existing thermal insulation methods for building walls, such as the use of non-heat conductor panels and thermal paints, suffer from mechanical weakness, toxicity, high installation costs, humidity issues leading to mold formation, and disposal problems, while providing only modest thermal conductivity reduction.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If non-heat conductor panels (polystyrene or rock wool) are applied to wall surfaces to reduce thermal losses, then thermal insulation performance is improved, but mechanical strength and structural reliability deteriorate

Engineering Contradiction:

Core Design Contradiction:
Loss of energyVSStrength

Solution Approach 1:

The patent uses a composite material system combining organic fibers (cellulose, wood, cork) with inorganic binders (gypsum, cement, lime) to create insulation panels that maintain both thermal insulation properties and mechanical strength. This composite approach allows the material to exhibit both low thermal conductivity and high structural integrity, resolving the contradiction between insulation performance and mechanical strength.

Solution Approach 1:

The patent changes the chemical composition parameters of insulation materials by replacing synthetic polymers (polystyrene) and mineral wool with natural organic materials (cellulose, wood fibers, cork) that degrade into non-toxic substances. This parameter change in material composition eliminates the generation of harmful degradation products while maintaining thermal insulation performance.
