Solution Overview

Problem

Existing surface temperature control systems face issues with moisture penetration due to perforation of the carrier film, leading to compromised thermal and sound insulation, and require additional costly installation steps for insulating materials.

Innovation Solution

A surface temperature control system featuring a flexible plastic tube with a Velcro connection, a carrier film glued or laminated onto a heat and sound insulating mat without penetrating seams, and stabilizing seams that run through the entire thickness of the mat for enhanced stability and moisture resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the carrier film is attached to the insulating layer by means of tacking, sewing, twisting or braiding, then the carrier film is fixed to the insulation layer, but the carrier film is perforated creating holes that allow water penetration

Engineering Contradiction:
Improveattachment strengthVSAvoidmoisture tightness
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The harmful effect of perforation is eliminated by extracting the stitching/tacking process and replacing it with a welding process that seals the carrier film rather than penetrating it, thus removing the source of water penetration while maintaining attachment strength

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A welding process acts as an intermediary method to join the carrier film to the insulating layer without mechanical penetration, using heat and pressure to create a bond that maintains the integrity of the carrier film's moisture barrier function

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a thin dimensionally stable flat carrier is used, then the installation is simpler and faster, but the thermal conductivity resistance requirements of EN 1264 are not met

Engineering Contradiction:
Improveinstallation speedVSAvoidthermal insulation performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The functions of the carrier film and the insulating layer are merged into a single integrated unit where the carrier film is welded directly to the insulating layer, eliminating the need for separate attachment steps and additional insulating material layers, thus maintaining installation speed while meeting thermal performance requirements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier film serves multiple functions: it provides mechanical support for the pipes, acts as a moisture barrier, and when welded to the insulating layer, becomes part of the thermal insulation system, eliminating the need for separate functional layers

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

3Strength

If seams penetrate the carrier film to attach it to the insulation layer, then the attachment is secure, but the liquid-tight protective function of the carrier film is impaired

Engineering Contradiction:
Improveattachment securityVSAvoidwater penetration
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The welding process converts the potential harm of heat application into a benefit by melting and fusing the carrier film material to the insulating layer, creating a sealed bond that actually enhances the moisture barrier function rather than compromising it

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
