Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing large-area temperature-controlled floor coverings are time-consuming and costly, particularly in underfloor heating systems where pipes or hoses need to be laid and fixed by hand, and electric heating systems require electrical energy conversion, reducing efficiency.
Innovation Solution
A method involving the formation of a screed layer with pre-formed grooves for inserting heating or cooling pipes, where the pipes are laid and fixed within the screed layer using a sealing layer, allowing for efficient and cost-effective installation without additional fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pipes or hoses are laid and fixed by hand in wet underfloor heating systems, then the heating system can be installed, but the expenditure of time and money increases considerably
Solution Approach 1:
The invention applies preliminary action by pre-forming grooves in the screed layer before pipe installation. The grooves are created in the uncured screed material, allowing pipes to be easily inserted and positioned without manual laying and fixing operations. This preliminary preparation of the screed structure significantly reduces installation time and labor requirements while maintaining proper pipe positioning.
2Ease of manufacture
If grooves are cut or milled out of a solid, hardened covering to lay heating coils, then the heating system can be installed, but the process becomes time-consuming
Solution Approach 1:
The invention reverses the conventional sequence by forming grooves in the uncured screed layer before it hardens, rather than cutting grooves into hardened concrete. This preliminary action allows the grooves to be created easily during the screed application process itself, eliminating the need for subsequent time-consuming cutting or milling operations and significantly improving installation productivity.
3Temperature
If electrical energy is used for heating surfaces, then heating can be achieved, but electrical energy must be available and waste heat conversion reduces efficiency
Solution Approach 1:
The invention replaces electrical heating systems with a hydraulic heating system using water or other fluids circulated through pipes embedded in the screed layer. This substitution eliminates the need for electrical energy conversion of waste heat, directly utilizing thermal energy from heat sources or cooling systems to heat or cool the floor surface, thereby improving overall energy efficiency.

AI summary
The method involves forming a screed layer (1) e.g. asphalt supporting layer, from a malleable or fluent granular or liquid material, where the screed layer comprises a surface profile with a groove or multiple grooves. A pipeline is moved into the grooves of the surface profile, and a closure layer is moved by covering the pipeline with a closure material. The surface profile is partially formed with the mold of the screed layer. One of the grooves is partially formed as linear grooves in a direction of an application of a floor material. Independent claims are also included for the following: (1) a grid module (2) a large scale, moderate temperature floor covering.
