Solution Overview
Problem
Existing insulating elements in facade constructions, while improving thermal insulation, often hinder the removal of moist air, leading to condensate accumulation and potential damage due to limited ventilation options.
Innovation Solution
An insulating element with transversely connected depressions on its side surfaces and internal cavities that facilitate additional ventilation, allowing for improved air exchange without compromising thermal insulation, and featuring passages that guide screws or fasteners, enabling moisture to be directed from the inner seal to the outer seal for discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If an insulating element is used in the rebate space to improve thermal insulation properties, then thermal insulation is improved, but the removal of moist air is slowed down leading to condensate accumulation
Solution Approach 1:
The insulating element is segmented into multiple sections with longitudinal and transverse passages that divide and channel moist air flow through defined paths from the inner seal area to the outer seal area, enabling effective moisture removal while maintaining insulation
Solution Approach 2:
The insulating element acts as an intermediary structure between the inner and outer seals, providing a controlled pathway for moisture transport while simultaneously serving as a thermal barrier. The passages within the insulating element mediate the moisture removal process without compromising the overall insulation performance
2Ease of operation
If ventilation chambers are created by indentations on side surfaces, then ventilation is improved, but thermal insulation properties are significantly reduced
Solution Approach 1:
The insulating element features localized ventilation passages and chambers positioned specifically in regions where moisture removal is most critical, while maintaining solid insulating material in other areas to preserve thermal insulation performance
Solution Approach 2:
The ventilation system utilizes three-dimensional passages running through the insulating element in longitudinal and transverse directions, creating volumetric ventilation chambers rather than simple surface indentations, which improves ventilation efficiency while minimizing impact on thermal insulation
3Ease of operation
If passages run through the insulating element to enable moisture transport, then moisture removal is improved, but the insulating properties are compromised
Solution Approach 1:
The insulating element incorporates a controlled porous structure with passages and chambers that allow moisture vapor transport while the surrounding solid insulating material maintains thermal barrier functionality
Solution Approach 2:
The insulating element functions as a composite structure combining solid insulating material with integrated ventilation passages, creating a multi-functional component that simultaneously provides thermal insulation and moisture transport capabilities
