Solution Overview

Problem

Existing floor heating systems are technically complex, prone to component damage during installation, suffer from poor heat conductivity and high maintenance challenges, and are limited to single-use applications for either water or electric heating.

Innovation Solution

A floor integrated system featuring a floor tile with grooves connected to a base plate via a support assembly that includes a heat conducting piece and positioning support in an up-and-down lapping mode, with a reflecting film for enhanced heat retention, modular design for easy assembly and repair, and adaptable for both water and electric heating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional floor heating methods (water or electric) are used with traditional installation approaches, then heating function is achieved, but the installation process becomes technically complicated and requires considerable site operation

Engineering Contradiction:
Improveinstallation convenienceVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the heating pipe support function directly into the floor tile structure by forming grooves on the bottom surface of the floor tile. This merging of support function into the floor tile eliminates the need for separate support components and complex installation procedures, thereby simplifying the overall installation process while maintaining heating functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The floor tile is segmented with multiple grooves formed on its bottom surface, allowing independent positioning and support of heating pipes within each groove. This segmentation enables flexible adaptation to different heating pipe layouts while maintaining a simple overall structure, reducing installation complexity

Inventive Principle:
Principle #1Segmentation

2Reliability

If conventional floor heating tiles are used before concrete sets, then floor heating installation is enabled, but the components laid are at risk of being damaged and the tiles tend to tilt

Engineering Contradiction:
Improvecomponent protectionVSAvoidfloor tile stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The heating pipes are pre-positioned within the grooves formed on the bottom surface of the floor tile before concrete pouring. This preliminary positioning ensures that the pipes are protected from damage during concrete setting and prevents floor tile tilting, as the pipes are securely held within the groove structures rather than being loosely laid on the surface

Inventive Principle:
Principle #10Preliminary action

3Loss of energy

If conventional floor heating tiles are used, then floor heating is achieved, but the heat conducting effect between the tile and set concrete is poor leading to heat loss

Engineering Contradiction:
Improveheat lossVSAvoidheat conducting performance
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The floor tile is designed with grooves on its bottom surface that create localized contact points with the concrete subfloor. This local quality enhancement ensures concentrated heat transfer zones where the heating pipes are positioned, improving heat conducting effectiveness between the tile and concrete while reducing overall heat loss through the floor structure

Inventive Principle:
Principle #3Local quality

4Ease of repair

If conventional floor heating tiles with large overall thickness are used, then structural integrity is maintained, but maintenance and repair become challenging in case of pipe or wire breakdown

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidfloor tile thickness
Core Design Contradiction:
Ease of repairVSLength of stationary object

Solution Approach 1:

The floor tile is designed with grooves that segment the internal space, allowing heating pipes to be positioned in dedicated channels. This segmentation enables easier access to pipes for maintenance and repair by creating defined pathways, reducing the need to remove entire thick floor tile sections while maintaining structural integrity

Inventive Principle:
Principle #1Segmentation
