Solution Overview

Problem

Existing radiant heating and cooling systems face inefficiencies due to significant temperature drops across interior cladding materials, such as plasterboard and engineered wood flooring, which hinder the effective use of low-temperature radiant heating systems and increase energy consumption.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional interior cladding materials (plasterboard, engineered wood flooring) are used in radiant heating systems, then the systems can be installed with simple cladding structures, but significant temperature drops occur across the cladding reducing heating efficiency

Engineering Contradiction:
Improvetemperature dropVSAvoidcladding structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies composite materials by combining conventional cladding materials (plasterboard, engineered wood flooring) with integrated thermal bridges made of high-conductivity materials. This creates a composite cladding structure that maintains the aesthetic and structural properties of conventional materials while adding thermal conduction pathways to reduce temperature drops and improve energy efficiency.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies local quality by incorporating thermal bridges at specific locations within the cladding structure rather than uniformly modifying the entire cladding. The thermal bridges are strategically positioned to create localized high-conductivity pathways that address temperature drops at critical points while maintaining the overall simplicity of the cladding structure.

Inventive Principle:
Principle #3Local quality

2Productivity

If high-conductivity thermal bridges are integrated into cladding to reduce temperature drops, then heat transfer efficiency improves, but the manufacturing and installation complexity increases

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent applies merging by combining the thermal bridge function with the cladding structure itself, rather than treating them as separate components. The thermal bridges are integrated into the cladding manufacturing process, allowing both elements to be produced as a single unit, which simplifies installation while achieving improved heat transfer efficiency.

Inventive Principle:
Principle #5Merging (Combining)

3Use of energy by stationary object

If thermal bridges are added to improve radiant heating efficiency, then energy consumption decreases, but the cladding design becomes more complex

Engineering Contradiction:

Solution Approach 1:

The patent applies the intermediary principle by introducing thermal bridges as mediator elements between the radiant heating system and the interior space. These thermal bridges act as intermediate conduits that facilitate heat transfer through the cladding, reducing energy consumption while adding only minimal complexity to the overall cladding design.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The efficiency of radiant space heating or cooling is improved and the use of renewable energy sources enabled by reducing the resistance of the thermal path through cladding used in the floor, walls or ceiling of a domestic or commercial living space. The resistance of the thermal path is reduced by constructing the cladding with an array of thermal bridges each comprising a thermal shunt connected to a heat-collecting layer and to a heat-dispersing layer. Such bridged cladding extends the range of choice of interior cladding and of configuration of radiant system. As an example, engineered wood floor is bridged below the veneer by embedded spiral aluminium (FIG 12b)
