Efficient Heating Mat Design with Reduced Costs and Enhanced Longevity
Here’s PatSnap Eureka !
Summary
Problems
Existing electrical heating mats face high manufacturing and installation costs due to the need for high currents to achieve required heating power, which increases the cost of cables, power supplies, and other components, and they suffer from increased electrical resistance over time due to oxidation of conductive fibers.
Innovation solutions
The heating mat features a support layer with an isolating surface and a heating layer comprising multiple electrically conductive stripes, which reduces the amount of expensive conductive material needed and allows for efficient voltage distribution by connecting stripes in series and parallel, along with a controller to manage voltage bursts to maintain low resistance.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If conventional heating mats with low resistance are used, then heating power is achieved, but high currents are required which increase the cost of cables, power supplies, and other components
Why choose this principle:
The heating layer is divided into multiple conductive stripes instead of using a continuous low-resistance conductive layer. This segmentation allows the system to achieve the required heating power through series-parallel connections, reducing the current requirement and associated component costs while maintaining manufacturing simplicity
Principle concept:
If conventional heating mats with low resistance are used, then heating power is achieved, but high currents are required which increase the cost of cables, power supplies, and other components
Why choose this principle:
The electrical resistance parameter of the heating layer is optimized by using multiple conductive stripes with controlled resistance values. By adjusting the number, width, and arrangement of stripes, the system achieves appropriate resistance to reduce current requirements while maintaining heating power output

Abstract
A heating mat 1 for a floor heating or a wall heating with a support layer 10 with an upper isolating surface 12 and a heating layer on top of the isolating surface 12 can be manufactured particularly efficient, if the heating layer comprises at least two electrically conductive stripes 20, each having a longitudinal extension and a width and if the two electrically conductive stripes 20 are horizontally spaced from each other, wherein an isolating stripe 30 extends in between of the two conductive stripes 20.
