Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heatable covering systems for floors, ceilings, and walls with electrically conductive layers tend to crack, affecting appearance and reliability, and are prone to cracking above certain thicknesses, leading to impaired electrical conductivity and heating capacity.
Innovation Solution
Incorporating a reinforcement layer, such as fleece or paper, that is embedded in the electrically conductive layer during the drying process, which absorbs moisture and maintains even distribution of conductive components, preventing cracking and allowing for thicker conductive layers without compromising conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electrically conductive layer is applied as a fluid and dried out, then the heating means can be produced with simple application methods, but the layer tends to crack which adversely affects appearance and reliability
Solution Approach 1:
The patent combines the electrically conductive layer with a reinforcement layer (such as fabric, paper, or mesh) to create a composite structure. This composite material prevents cracking while maintaining electrical conductivity, as the reinforcement layer provides structural integrity to the otherwise brittle dried conductive material.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the electrically conductive layer by incorporating binders and additives that control drying behavior and shrinkage. By adjusting composition parameters such as solids content, viscosity, and drying rate, the patent prevents crack formation during the drying process while maintaining electrical conductivity.
2Power
If the electrically conductive layer thickness is increased to improve heating capacity, then more heating power is available, but the layer develops increased cracking tendency
Solution Approach 1:
The reinforcement layer embedded in the electrically conductive layer provides structural support that enables thicker applications without cracking. The composite structure distributes stress evenly throughout the layer, allowing increased thickness for higher heating capacity while maintaining integrity.
Solution Approach 2:
The patent introduces a third dimension by embedding a reinforcement layer within the conductive layer structure. This additional structural dimension provides crack resistance while allowing the conductive material to be applied in thicker configurations for enhanced heating power.
3Reliability
If the electrically conductive layer is made thinner to prevent cracking, then cracking is reduced, but the heating capacity is limited
Solution Approach 1:
The composite structure allows thin applications of conductive material to maintain crack resistance while the embedded reinforcement layer provides the structural integrity needed to prevent cracking. This enables thin-layer applications that would otherwise be too brittle.
Solution Approach 2:
The reinforcement layer acts as a flexible substrate that supports the thin electrically conductive layer, preventing it from becoming too brittle. This flexible support structure enables thin-film applications that maintain both crack resistance and adequate heating capacity.
4Temperature
If conventional underfloor heating systems are installed to achieve even heat distribution, then pleasant heating is achieved, but material costs and installation expenses are very high
Solution Approach 1:
The patent combines the heating function with the floor covering itself by applying the electrically conductive layer directly to the underside of the covering panel. This merging of heating and covering functions eliminates the need for separate heating pipe systems and reduces installation complexity.
Solution Approach 2:
The patent replaces the mechanical hydraulic system (water pipes) with an electrical system (conductive layer). This substitution simplifies the overall system by eliminating complex pipe laying, connections, and hydraulic control mechanisms while maintaining even heat distribution through the conductive layer.

AI summary
The heatable covering system has covering panel (26) with a decorative upper surface (11) and a lower surface (12), particularly laminated plates, veneer plywood, and parquet plates. The covering panel is provided with coupling units at longitudinal edges for interconnecting the covering panels. An electrical heating medium (24) is provided at the covering panels. The electrical heating medium consists of an electrically conducting fluid which is applied on the covering panels and a reinforcement layer which is embedded partially in the electrically conducting layer.
