Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal insulation panels for masonry fail to effectively manage moisture, leading to condensation, mold growth, and reduced thermal insulation due to poor capillary activity and thermal bridges, while requiring significant thickness for standard insulation performance.
Innovation Solution
A thermal insulation panel design featuring capillary-active cover and boundary layers with free spaces enclosed by capillary-active webs, allowing for efficient moisture drainage and improved thermal insulation with a thinner panel thickness, using materials like calcium silicate, perlite, and mineral foam, and optionally incorporating VIP panels for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional thermal insulation panels with waterproof foam glass or foam concrete are used, then thermal insulation is provided, but moisture management fails leading to condensation and mold growth
Solution Approach 1:
The insulation panel is segmented into multiple functional layers: a hydrophobic core layer for thermal insulation, capillary-active outer layers for moisture management, and a drainage layer for water removal. This segmentation allows each layer to perform its specific function optimally without interfering with others.
Solution Approach 2:
Different regions of the panel have different material properties tailored to local requirements. The core layer uses low-capillarity material for thermal insulation, while the outer layers use high-capillarity materials for moisture transport. This local differentiation resolves the contradiction between thermal insulation and moisture management.
2Length of stationary object
If VIP panels with plastic frames are used to achieve high thermal insulation with reduced thickness, then thermal insulation performance improves, but thermal bridges form at frame areas leading to condensation and mold growth
Solution Approach 1:
The problematic plastic frames that create thermal bridges are completely removed from the design. Instead, the VIP panels are directly embedded in the capillary-active outer layers which provide both mechanical protection and moisture management, eliminating the source of thermal bridges while maintaining structural integrity.
3Loss of energy
If standard thermal insulation panels with thick construction are used, then adequate thermal insulation is achieved, but significant interior space is lost
Solution Approach 1:
The panel uses a composite structure combining VIP panels (extremely low thermal conductivity) with thin capillary-active layers. This composite approach achieves superior thermal insulation performance with dramatically reduced thickness compared to conventional homogeneous insulation panels, preserving interior space while meeting or exceeding insulation requirements.
4Reliability
If capillary-active materials are used for moisture drainage, then moisture management improves, but thermal insulation performance decreases due to higher thermal conductivity
Solution Approach 1:
The panel is divided into distinct functional zones where capillary-active materials are confined to thin outer layers dedicated to moisture management, while the thick core layer uses low-capillarity VIP panels for thermal insulation. This segmentation minimizes the thermal penalty of capillary materials while maximizing their moisture management benefits.

AI summary
The board has chambers (6) arranged between a covering layer plate (4) and a barrier layer for arrangement at a masonry (1). The chambers have a heat insulating unit (8) of low thermal conductivity. The covering layer plate and the barrier layer serve as a barrier layer plate (3) made of capillary-active insulation material. The chambers are enclosed by capillary-active chamber bars (5) at all sides. The chamber bars are capillary-active connected with the covering layer plate and the barrier layer plate. The chamber bars are connected with the covering and barrier layer plates. An independent claim is also included for a kit for assembly of a thermal insulation board.
