Solution Overview

Problem

Existing surface temperature control systems require additional layers of insulating material and complex installation processes, which increase costs and complexity, while failing to meet high insulation standards.

Innovation Solution

A surface temperature control system featuring a dimensionally stable, flat carrier designed as a 1 cm to 20 cm thick polymer foam insulation layer with a metal-coated composite cover film, combined with a flexible plastic tube using a Velcro connection for easy installation and enhanced insulation, where the carrier film and cover film are processed in a foaming device to form the polymer foam insulation layer and the Velcro connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a thin dimensionally stable flat carrier is used, then the structure is simple, but the insulation properties are insufficient and additional insulating layers are required

Engineering Contradiction:
Improvestructure simplicityVSAvoidinsulation properties
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The patent combines the carrier function and insulation function into a single integrated component. The dimensionally stable flat carrier is designed with sufficient thickness (at least 5 mm, preferably 7-10 mm) to provide both structural support and thermal insulation, eliminating the need for separate insulating layers and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The dimensionally stable flat carrier serves multiple functions simultaneously: it provides mechanical support for the flexible tubes, ensures dimensional stability during installation, and provides thermal insulation. This multi-functional design resolves the contradiction by making one component perform both structural and insulating roles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of energy

If additional insulating layers are added, then the insulation properties improve, but the installation complexity and costs increase

Engineering Contradiction:
Improveinsulation propertiesVSAvoidinstallation complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the insulation layer with the carrier into a single integrated component. The carrier is designed with adequate thickness to provide the required insulation performance, eliminating the need for separate insulating layers and simplifying the installation process to a single step.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of energy

If the carrier thickness is increased, then the insulation properties improve, but the weight and material consumption increase

Engineering Contradiction:
Improveinsulation propertiesVSAvoidmaterial consumption
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The patent optimizes the carrier thickness parameter to at least 5 mm (preferably 7-10 mm) to achieve the required insulation performance while minimizing material consumption. This parameter optimization resolves the contradiction by finding the minimum sufficient thickness that provides adequate insulation without excessive material use.

Inventive Principle:
Principle #35Parameter changes
