Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building panels with embedded piping for heating or cooling have poor thermal conductivity, making them inefficient in withstanding rapid temperature changes and distributing heat gradients effectively.
Innovation Solution
A rigid mortar board with a significant proportion of elemental carbon additives, combined with a metal pipe system and a core layer of lightweight material, enhances thermal conductivity and even heat distribution, while a frame mold ensures proper embedding and curing of the mortar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If normal construction or cement mortar is used for building panels with embedded piping, then the structure provides mechanical strength and stability, but the thermal conductivity is poor
Solution Approach 1:
The patent applies composite materials by combining cement mortar with graphite particles (elemental carbon) to create a new material composition. The graphite particles are dispersed throughout the mortar matrix, forming a composite that maintains the mechanical properties of cement while adding high thermal conductivity characteristics from the graphite, thereby resolving the contradiction between structural strength and thermal performance
Solution Approach 2:
The patent changes the physical-chemical parameters of the mortar by incorporating graphite particles with specific properties (high thermal conductivity, lamellar structure). This parameter modification transforms the mortar from a thermally insulating material to a thermally conductive composite, enabling effective heat distribution while maintaining structural integrity
2Ease of manufacture
If polystyrene foam boards are used to attach heating pipes, then the pipes can be mounted, but the panels cannot withstand rapid temperature changes effectively
Solution Approach 1:
The patent replaces pure polystyrene foam with a composite material consisting of cement mortar enhanced with graphite particles. This composite maintains the ease of pipe attachment provided by foam-like materials while dramatically improving thermal conductivity and temperature stability, allowing the panel to withstand rapid temperature changes without cracking or deforming
Solution Approach 2:
The patent introduces graphite particles with specific local properties (high thermal conductivity, thermal stability) into the mortar matrix where they are needed to enhance temperature load resistance. The graphite particles are distributed throughout the material to provide localized thermal management capabilities while maintaining overall structural properties
3Reliability
If a high proportion of elemental carbon aggregate is added to increase thermal conductivity, then heat distribution improves, but the compatibility with mortar mass must be maintained
Solution Approach 1:
The patent optimizes the parameters of the graphite particles, specifically controlling particle size distribution and shape, to ensure compatibility with the mortar matrix. By selecting appropriate graphite particle dimensions and surface characteristics, the patent achieves good dispersion and bonding within the cement mortar, maintaining composition stability while maximizing thermal conductivity enhancement
Solution Approach 2:
The patent applies local quality by using graphite particles with specific surface properties and size distributions that enhance compatibility with mortar. The particles are designed to have surface characteristics that promote bonding with cement while maintaining thermal conductivity, creating optimal local interactions between the graphite additive and mortar matrix

AI summary
The panel (100) has a pipe line (2) with hot or cold fluid for space heating or cooling while mounting on a wall, a ceiling or a floor. A core layer (1) consists of a foam glass plate, and a reinforcing layer (6) made of a fiber glass mat is provided at a rear side of the core layer. The pipe line partially lies at a front side of the core layer or partially embedded on an outer surface of the front side of the core layer. The pipe line is provided with metal selected from corrosion-free steel and copper, and is formed as a connecting pipe.
