Solution Overview

Problem

Existing electrically-supplied heating panels face issues with costly external insulating layers and non-uniform heat diffusion due to inadequate adhesive application, leading to poor mechanical seal and heat distribution.

Innovation Solution

A heating panel design featuring a support with a polymer coupling layer that embeds between the weft and warp of a heating fabric, ensuring a strong, uniform connection and consistent heat transmission without external insulating layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If adhesive material is applied only in specific zones (edges or random points) to limit installation time and save materials, then installation efficiency is improved, but the mechanical seal quality deteriorates and heat diffusion uniformity worsens

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidmechanical seal quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies adhesive material in specific zones (edges or distributed points) rather than uniformly across the entire surface. This partial action approach achieves sufficient mechanical seal and heat diffusion while reducing adhesive material consumption and installation time, resolving the contradiction between installation efficiency and seal quality.

Inventive Principle:
Principle #16Partial or excessive action

2Loss of time

If adhesive material is applied in zones with insufficient air, then installation time is reduced, but the reticulation of adhesive deteriorates leading to poor fixing quality

Engineering Contradiction:
Improveinstallation timeVSAvoidadhesive reticulation quality
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The patent applies adhesive material in specific localized zones (edges or distributed points) where air entrapment is minimized. This local quality approach ensures sufficient aeration for proper reticulation while maintaining installation efficiency, resolving the contradiction between installation time and adhesive reticulation quality.

Inventive Principle:
Principle #3Local quality

3Loss of energy

If external insulating layers are provided on heating panels, then thermal insulation is improved, but production costs and device complexity increase

Engineering Contradiction:
Improvethermal insulationVSAvoidpanel structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the adhesive layer with the insulating function by using the adhesive material itself as the insulating layer. This combination eliminates the need for separate external insulating layers, reducing device complexity and production costs while maintaining thermal insulation performance.

Inventive Principle:
Principle #5Merging (Combining)

4Quantity of substance

If adhesive is applied with non-uniform thickness or in inconsistent zones, then material usage is optimized, but heat diffusion uniformity deteriorates

Engineering Contradiction:
Improveadhesive material usageVSAvoidheat diffusion uniformity
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent applies adhesive material in specific zones (edges or distributed points) with controlled thickness. This partial action approach optimizes adhesive material usage while maintaining sufficient heat diffusion uniformity through strategic placement in areas that do not critically affect thermal distribution.

Inventive Principle:
Principle #16Partial or excessive action
