Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior insulation systems face issues with water condensation leading to moisture accumulation, which can cause damage to building structures due to the lack of a water buffer and thermal bridging, especially in old buildings where exterior insulation is not feasible.
Innovation Solution
Incorporating a gutter profile with a cavity and a third mineral wool insulation element to store and evaporate condensed water, reducing thermal conductivity and preventing damage by creating a water buffer and anti-microbial properties to prevent mould growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a wicking media is used to transport condensate away from the insulation interface, then moisture transport capability is improved, but the system lacks a water buffer and cannot prevent water from damaging building structures
Solution Approach 1:
The patent introduces a porous water buffer layer positioned between the insulation system and the building structure. This layer absorbs and stores excess condensate water through capillary action, preventing it from reaching and damaging the building structure while allowing controlled evaporation back into the room. The porous structure provides both moisture storage capacity and controlled release mechanisms.
2Ease of manufacture
If the lower part of the insulation system is not insulated, then installation simplicity is maintained, but it creates a thermal bridge that increases the risk of water soaking the floor
Solution Approach 1:
The patent applies insulation material specifically to the lower part of the insulation system where thermal bridging occurs. By locally insulating this critical area, the system prevents cold temperatures that would cause condensate to pool and soak the floor, while maintaining the overall simplicity of the installation process. This targeted approach addresses the thermal bridge issue without requiring complete re-insulation of the entire system.
3Productivity
If condensed water evaporates quickly back into the room, then moisture accumulation is reduced, but the system cannot provide a water buffer for delayed release
Solution Approach 1:
The patent utilizes phase transitions of water (liquid condensate → vapor) in a controlled manner. The water buffer layer stores condensate in liquid form and releases it slowly as vapor through controlled evaporation, providing both immediate moisture management and delayed release capabilities. This phase change mechanism allows the system to act as both a quick-response and long-term moisture control system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively manages condensed water by storing it in the gutter profile for delayed evaporation, reducing the risk of damage and thermal bridging, while preventing mould growth through anti-microbial treatments.
Implementation Method 1
The water vapour or condensed water can also be confined in the third mineral wool insulation element inside the profile and evaporate through the ventilation opening(s) into the interior room of the building
Implementation Method 2
by providing a third mineral wool insulation element in the cavity of the gutter profile, the thermal conductivity of the lower profile structure and any unwanted thermal bridging is reduced
Implementation Method 3
the water vapour absorbed in the first mineral wool insulation can be transported via the upper opening and into the gutter profile
Implementation Method 4
a wicking media in the insulation product to transport the condensate away from the interface between the insulating product and the exterior wall
