Solution Overview

Problem

Existing thermal insulation systems for buildings face challenges in preventing moisture damage, particularly when external insulation is used, as they can move the dew point into the wall, leading to potential moisture penetration and damage, and existing solutions that address this often compromise thermal insulation properties or require significant investment.

Innovation Solution

A system that attaches thermal insulation to the inside of external walls or roofs, creating a cavity into which temperature-controlled air is circulated, allowing heat to be transferred to the paneling and stored, thereby regulating room temperature and preventing moisture damage through controlled air flow and heat distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If thermal insulation is installed on the exterior of building walls, then thermal insulation performance is improved, but moisture penetration risk increases due to dew point shifting into the wall

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidmoisture penetration risk
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional approach by installing thermal insulation on the interior side of the wall rather than the exterior. This reversal prevents the dew point from shifting into the wall structure, eliminating the moisture penetration risk while maintaining thermal insulation performance. The interior insulation is combined with a cavity and cladding system to manage moisture and heat effectively.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a cavity between the interior insulation and the cladding as an intermediary element. This cavity serves multiple functions: it allows for moisture management, provides an air circulation path, and maintains the effectiveness of the thermal insulation while preventing moisture accumulation in the wall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a vapor-tight layer is installed on the room-facing side to prevent moisture penetration, then moisture protection is improved, but thermal insulation properties are reduced

Engineering Contradiction:
Improvemoisture protectionVSAvoidthermal insulation properties
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent uses a vapor-permeable membrane instead of a traditional vapor-tight layer. This membrane allows water vapor to pass through while still providing moisture protection, thereby maintaining thermal insulation properties. The membrane is integrated into the cladding system, allowing it to perform both moisture management and thermal functions without compromise.

Inventive Principle:
Principle #30Flexible shells and thin films

3Object-affected harmful factors

If calcium silicate boards are used for vapor-permeable insulation, then moisture protection is improved, but investment cost and reduction in thermal insulation properties increase

Engineering Contradiction:
Improvemoisture protectionVSAvoidinvestment cost and thermal insulation reduction
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent creates a multi-functional system where the cladding serves multiple purposes: it acts as a moisture barrier, a thermal mass for heat storage, and a surface for the heating system. This eliminates the need for expensive specialized materials like calcium silicate boards, as the regular cladding materials perform all necessary functions including moisture protection and thermal regulation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines several functions into a single integrated system: thermal insulation, moisture protection, heat storage, and surface heating are all merged into one system comprising interior insulation, cavity, and cladding. This integration eliminates the need for separate expensive components and achieves cost-effective moisture protection without compromising thermal insulation.

Inventive Principle:
Principle #5Merging (Combining)
