Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-layer wall structures fail to effectively utilize the thermal advantages of both wood and inorganic materials for improved heat exchange and insulation, often leading to issues like mold growth, inefficient heat capacity, and aesthetically unpleasing designs.
Innovation Solution
A wall structure with a wood layer spaced from an inorganic carrier layer using wooden dowels or screws as spacer elements, incorporating thermally conductive cast layers for efficient heat exchange, and optionally featuring a laminated wood element for enhanced insulation and fire safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brick wall is positioned outside the wooden wall to protect it from the elements, then the supporting layer is protected, but the thermal conductivity increases and the temperature drops below dew point causing mold growth
Solution Approach 1:
The wall is divided into multiple functional layers: an inner wooden wall layer, an insulating layer, and an outer brick support layer. This segmentation allows each layer to perform its specific function - the wooden layer provides interior finishing and moisture regulation, the insulating layer prevents thermal bridging and maintains temperature above dew point, and the brick layer provides structural support and exterior protection.
Solution Approach 2:
An insulating layer is introduced as an intermediary between the wooden wall and the brick support layer. This intermediary layer has low thermal conductivity, which prevents heat transfer that would otherwise cause the brick layer temperature to drop below dew point. The insulating layer mediates the thermal interaction between the two wall layers, eliminating the harmful effect of condensation and mold growth.
2Loss of energy
If insulation material is placed between the wood layer and inorganic layer, then insulation value increases, but thermal advantages of different layers cannot be utilized
Solution Approach 1:
Different layers of the wall are assigned different thermal properties optimized for their specific locations and functions. The inner wooden layer has moderate insulation properties and high heat capacity for interior comfort, while the outer brick layer has high thermal mass for absorbing external temperature variations. The insulating layer between them has very low thermal conductivity to minimize heat transfer. This local differentiation of thermal qualities allows each layer to contribute its specific thermal advantage.
Solution Approach 2:
The wall construction uses a composite structure combining organic wood material and inorganic brick material with an insulating layer in between. This composite design leverages the complementary thermal properties of different materials - the wood provides interior finishing and moisture regulation, the insulation minimizes heat transfer, and the brick provides structural support and thermal mass. The composite structure enables both layers to contribute their thermal advantages simultaneously.
3Use of energy by moving object
If pipes are attached to wall layers using clips or aluminum sheets, then heat exchange is improved, but thermal bridges are created negatively impacting heat transfer
Solution Approach 1:
Instead of using metal clips or sheets that create thermal bridges, the patent uses wooden spacers as intermediaries to attach the heating pipes to the wall layers. These wooden spacers have thermal conductivity similar to the wooden wall layer, creating a continuous thermal path without abrupt conductivity changes. This intermediary approach maintains thermal uniformity across the wall structure while still enabling effective heat transfer from the pipes to the wall and subsequently to the interior space.
