Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying electric heating foils, with soft layers on both sides, result in inefficient heat emission and limited top layer application possibilities due to reduced heat transfer efficiency and absorption.
Innovation Solution
Attaching the electric heating foil directly to a hard surface using a single viscous adhesive layer and applying the top layer directly to the heating foil with the same adhesive, enhancing heat radiation and reducing absorption, with Semco Liquid Membrane as an ideal viscous material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If soft layers are applied on both sides of the heating foil, then the heating foil is protected and easily installed, but heat emission efficiency decreases due to heat absorption by the soft layers
Solution Approach 1:
The patent removes the soft insulating layers from both sides of the heating foil, extracting the harmful thermal insulation that was preventing efficient heat emission. The heating foil is instead mounted directly to a hard reflective surface, eliminating the thermal barrier while maintaining installation simplicity through direct attachment.
Solution Approach 2:
Instead of placing insulating soft layers on both sides of the heating foil as in conventional methods, the patent inverts the approach by using a hard reflective surface on the rear side and minimal adhesive layers on both sides, thereby inverting the thermal management strategy from insulation to radiation efficiency.
2Strength
If soft layers are used on both sides of the heating foil, then the heating foil is cushioned and protected, but the top layer application possibilities are limited
Solution Approach 1:
The patent extracts the thick soft cushioning layers that were limiting top layer applications, replacing them with thin adhesive layers that provide sufficient bonding without creating a thermal or physical barrier between the heating foil and the top layer, thereby enabling greater versatility in top layer material selection.
Solution Approach 2:
The patent uses thin adhesive films instead of thick soft layers, providing the necessary bonding function while maintaining thermal transparency and flexibility for various top layer applications. The thin film approach allows direct contact between the heating foil and diverse top layer materials.
3Strength
If thick soft layers are used on both sides of the heating foil, then the heating foil is well-cushioned, but heat radiation is absorbed and space heating efficiency decreases
Solution Approach 1:
The patent removes the thick cushioning soft layers that were absorbing heat radiation, extracting the excessive thermal insulation that prevented effective space heating. The heating foil is mounted with minimal adhesive layers to a hard reflective surface, eliminating the thermal barrier while maintaining structural support.
Solution Approach 2:
The patent inverts the conventional approach of using thick insulating layers for cushioning by using a hard reflective surface with thin adhesive layers, thereby inverting the thermal management from heat trapping to heat radiation, which improves space heating efficiency while providing sufficient cushioning through the adhesive layers alone.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method improves heating efficiency by minimizing heat absorption and maximizing space heating, particularly benefiting infrared heating foils by reducing the number of adhesive layers and allowing for better heat transfer.
Implementation Method 1
the heating foil is attached to a hard surface over the entire underside by means of a first viscous adhesive layer, and the top layer is attached directly to the heating foil over the entire top side of the heating foil by means of a second viscous adhesive layer
Implementation Method 2
a heating foil is provided with a bottom side which faces the substrate, as well as a top side which radiates heat
Implementation Method 3
resistance elements which become hot when they conduct current and in the form of radiant elements which radiate infrared radiation when they conduct current

AI summary
In a method for applying a heating foil, a heating foil 11 is over the entire underside attached to a hard surface 3 and an upper layer 5 is attached to the heating foil 11 over the entire top side of the heating foil 11. By fixing the heating foil 11 on a hard surface 3 and fixing the top layer 5 directly on the heating foil 11, a thin top layer will suffice, so that the infrared radiation is absorbed less and the space above the floor 1 is therefore better heated. The heating foil 11 is glued directly onto the hard substrate 3 by means of a first viscous adhesive layer 7 and the top layer 5 is glued directly onto the top side 11b of the heating foil 11 by means of a second viscous adhesive layer 9. The adhesive layers 7 and 9 are of the same viscous material Semco Liquid Membrane™ which is an elastomeric liquid suspended in a copolymer adhesive.
