Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing in-floor heating systems face challenges in securely locating and maintaining the position of wires or pipes, leading to uneven heating and potential damage, while also requiring efficient bonding of successive flooring layers.

Innovation Solution

A system featuring a base with protrusions, or bosses, that securely position heating elements and facilitate bonding between adhesive layers, including hollow bosses for weight reduction and enhanced heat retention, and openings for drainage and air permeability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wires or pipes are not securely positioned, then installation is simpler, but heating becomes uneven and wires may be damaged

Engineering Contradiction:

Improveheating uniformityVSAvoidpositioning structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The underlayment is divided into multiple cells, each containing positioning protrusions that independently secure wire or pipe segments. This segmentation allows simple localized positioning without complex overall structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Positioning protrusions act as intermediaries between the underlayment and heating elements (wires/pipes). These protrusions provide dedicated positioning points that ensure uniform spacing and secure placement without requiring complex external fixtures

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If successive adhesive layers cannot interact, then installation is faster, but bonding strength is reduced

Engineering Contradiction:

Improveadhesive bondingVSAvoidinstallation speed

Core Design Contradiction:

StrengthVSProductivity

Solution Approach 1:

The underlayment incorporates porous regions or channels that allow adhesive to penetrate through and interact with successive adhesive layers. This porous structure enables chemical bonding between layers while maintaining a relatively simple installation process

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The underlayment design enables continuous adhesive flow and interaction between successive adhesive layers through integrated channels or porous structures. This continuity ensures strong bonding without requiring complex multi-step installation procedures

Inventive Principle:

Principle #20Continuity of useful action

3Weight of moving object

If solid bosses are used for positioning, then structural strength is higher, but weight increases and heat retention decreases

Engineering Contradiction:

Improveunderlayment weightVSAvoidboss structural strength

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The positioning protrusions are designed as thin-walled or hollow structures that provide sufficient mechanical strength for positioning while minimizing weight. The shell-like structure maintains rigidity where needed while reducing overall mass compared to solid bosses

Inventive Principle:

Principle #30Flexible shells and thin films

4Reliability

If heating elements are not securely located, then installation is more flexible, but wire damage risk increases

Engineering Contradiction:

Improvewire protectionVSAvoidinstallation flexibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The underlayment is segmented into multiple cells with individual positioning protrusions for each heating element location. This segmentation provides dedicated protection zones for wires while allowing flexible routing within each cell compartment

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Positioning protrusions serve as intermediary protective structures between the underlayment and heating elements. These protrusions guide and secure wires/pipes during installation, preventing damage while maintaining installation flexibility through their distributed arrangement

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An underlayment system is provided that includes a plurality of bosses that emanate form a common base member. The bosses and bases preferably include an opening therethrough that will allow for subsequent layers of adhesive to interact and bond to each other. The bosses are also spaced in such a way to help secure a wire snugly therebetween.
