Solution Overview

Problem

Conventional building insulation systems, while effective in reducing thermal exchange, often restrict ventilation and mass exchange, leading to unhealthy indoor climates due to trapped volatile organic substances and increased summer heat loads, requiring thicker insulation layers and active cooling.

Innovation Solution

An insulation system comprising rectangular plastic cassettes with a tray and cover, forming an air chamber that can be filled with insulating material, allowing for thermal and fire-resistant properties, and featuring an air space for ventilation and mass exchange, which can be integrated into existing or non-insulated building walls, enabling effective heat and substance discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional insulation systems are used to reduce thermal exchange, then thermal insulation is improved, but ventilation and mass exchange are restricted leading to unhealthy indoor climates

Engineering Contradiction:

Improvethermal exchangeVSAvoidindoor air quality

Core Design Contradiction:

Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The insulation system is divided into separate modules (insulation panels with integrated ventilation channels), allowing thermal insulation and ventilation functions to be segmented yet integrated within the same structure, resolving the contradiction between reducing thermal exchange and maintaining air quality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Ventilation channels act as intermediary pathways within the insulation system, enabling mass exchange and ventilation while the insulation material itself maintains thermal barrier function, thus allowing both thermal protection and air quality maintenance simultaneously

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If thicker insulation layers are used to achieve required insulation values, then thermal insulation is improved, but device complexity and construction thickness increase

Engineering Contradiction:

Improvethermal insulationVSAvoidconstruction thickness

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The insulation panels serve multiple functions simultaneously: thermal insulation, ventilation, and structural support. This multi-functionality allows achieving required insulation values without increasing overall construction thickness, as the same component provides both insulation and air flow pathways

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Ventilation channels are nested within the insulation panel structure itself, allowing the insulation system to contain functional elements that provide ventilation without requiring additional external space, thus maintaining compact construction thickness

Inventive Principle:

Principle #7Nested doll (Nesting)

3Loss of energy

If conventional insulation systems are used, then thermal insulation is improved, but active cooling is required due to trapped heat and volatile substances

Engineering Contradiction:

Improvethermal insulationVSAvoidactive cooling

Core Design Contradiction:

Loss of energyVSUse of energy by moving object

Solution Approach 1:

The ventilation channels enable continuous passive air flow through the insulation system, providing ongoing heat and volatile substance discharge without requiring active cooling systems, thus maintaining thermal insulation while eliminating the need for energy-consuming cooling

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The insulation system serves itself by incorporating internal ventilation pathways that automatically discharge heat and volatile substances without external intervention or active cooling systems, allowing the insulation structure to maintain indoor climate passively

Inventive Principle:

Principle #25Self-service
