Floor Heating Element Embedded in Laminate Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor heating devices react slowly and deliver excessive heat to the floor, as the heating elements are typically placed underneath flooring materials, leading to inefficient heating and mechanical issues due to differential expansions.
Innovation Solution
Incorporating heating means, such as thin wires or cords with low electrical conductivity, within the flooring materials themselves, particularly between the carrying layer and décor paper in laminate panels, to provide faster and more focused heat distribution, and using a network or meshwork structure that integrates with the panel's layers for stability and reduced mechanical strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If heating means are arranged underneath flooring materials (stone plates, tiles, parquet elements, or laminate panels), then the heating device can be installed, but the heating response is slow and a large amount of heat is delivered to the floor instead of the room
Solution Approach 1:
The patent inverts the conventional placement of heating elements by moving them from underneath the flooring materials to inside the flooring materials themselves, specifically in the upper third layer. This inversion allows heat to be generated closer to the room space, eliminating the need for heat to penetrate through thick flooring layers, thereby improving heating response speed and reducing energy loss to the floor.
Solution Approach 2:
The patent transitions from a one-dimensional placement (underneath the flooring) to a three-dimensional integration (inside the flooring layers). By embedding heating means within the internal structure of the flooring materials, specifically in the upper third layer, the heat generation occurs in a different spatial dimension relative to the flooring surface, enabling faster heat transfer to the room.
2Speed
If heating means are placed inside the covering (in the stone plate, tile, parquet element, or laminate panel), then faster and more focused heating is achieved, but mechanical problems due to differential expansions and shrinkages may arise
Solution Approach 1:
The patent applies local quality by positioning heating means specifically in the upper third layer of the flooring material, rather than uniformly distributing them throughout. This localized placement optimizes heat transfer to the room while minimizing the impact on the overall structural integrity. Additionally, using thin wires or cords with low electrical conductivity provides localized heating elements that cause minimal mechanical disturbance.
Solution Approach 2:
The patent employs thin wires or cords with low electrical conductivity as heating means, which act as flexible elements within the flooring structure. These thin heating elements minimize mechanical disruption to the flooring layers while still effectively generating heat. The thin nature of these heating means allows them to accommodate differential expansions and shrinkages without causing significant mechanical problems.
3Reliability
If thin wires or cords with low electrical conductivity are used, then mechanical problems are reduced, but the electrical resistance must be carefully controlled to ensure sufficient heating performance
Solution Approach 1:
The patent applies parameter changes by carefully selecting and controlling the electrical resistance of the thin wires or cords used as heating means. By adjusting the electrical resistance parameter, the patent ensures sufficient heating performance while using thin, mechanically benign conductors. The low electrical conductivity of the thin wires is compensated by optimizing their resistance to generate adequate heat.
4Productivity
If a network or meshwork structure is incorporated into the flooring material, then production efficiency is improved and mechanical stability is enhanced, but the structure becomes more complex
Solution Approach 1:
The patent merges the heating function with the structural flooring layers by integrating heating means into the upper third layer of the flooring material. This merging allows the heating elements to be processed together with the flooring layers, improving production efficiency. The network or meshwork structure is combined with the flooring material layers, eliminating the need for separate installation steps.
Solution Approach 2:
The patent creates a multi-functional flooring structure where the upper third layer serves both as a structural component and as a housing for heating means. The network or meshwork structure provides both mechanical reinforcement and integrates the heating function, allowing a single structural element to perform multiple functions: structural support, heat generation, and production process integration.
