Solution Overview

Problem

Existing in-floor heating systems face issues with uneven heating and wire damage due to unsecured wires between studs, and hydronic systems require thicker floors and inefficient hot water storage tanks, while electric systems have limited heat transfer efficiency.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wires are placed between studs without securing mechanisms, then installation is simpler, but wires may separate causing uneven heating or wire damage

Engineering Contradiction:
Improveinstallation simplicityVSAvoidwire positioning stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The underlayment is divided into modular units with individual studs that have integrated wire routing features. Each stud acts as an independent segmentation unit that guides and secures wire segments, allowing simple installation while ensuring reliable wire positioning through the segmented structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stud protrusions serve as intermediary elements between the underlayment and the heating wires. These studs provide a physical interface that mediates the connection, guiding wires along their length and securing them in place without requiring additional fastening mechanisms, thus maintaining installation simplicity while ensuring wire stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If continuous mat is used for heating elements, then installation is faster, but subsequent adhesive layers cannot interact with previously placed layers

Engineering Contradiction:
Improveinstallation speedVSAvoidadhesive bonding
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The underlayment features localized textured regions or protrusions at specific intervals on the continuous mat. These localized features provide adhesive interaction points without disrupting the continuity of the mat itself, allowing fast installation while enabling subsequent adhesive layers to bond effectively at these specific locations.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The solution introduces vertical dimensionality through protruding studs or textured surfaces on the continuous mat. This dimensional change allows adhesive layers to interact with the underlayment in the vertical dimension while the mat remains continuous in the horizontal plane, thus maintaining both installation speed and adhesive bonding strength.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Loss of energy

If hydronic system with large diameter pipes is used, then heat transfer is effective, but floor thickness increases

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoidfloor thickness
Core Design Contradiction:
Loss of energyVSLength of stationary object

Solution Approach 1:

The patent applies hydraulic principles by using smaller diameter pipes designed for optimized water flow velocity and heat transfer efficiency. The system compensates for the reduced pipe diameter by controlling flow parameters, maintaining effective heat transfer while reducing the vertical space required and thus minimizing floor thickness.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Length of stationary object

If electric cables are installed directly onto sub floor, then floor buildup is minimal, but heat transfer to finished flooring is reduced

Engineering Contradiction:
Improvefloor buildup thicknessVSAvoidheat transfer efficiency
Core Design Contradiction:
Length of stationary objectVSLoss of energy

Solution Approach 1:

The underlayment with integrated heating elements and protruding studs serves as an intermediary layer between the sub floor and finished flooring. This intermediary structure provides a thermally conductive pathway that enhances heat transfer efficiency while maintaining minimal overall thickness, as the heating elements are positioned optimally within the thin underlayment structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An underlayment system is provided that includes a plurality of protrusions that extend from a common base member. The protrusions and base member can include an opening therethrough that allows for subsequent layers of material, such as adhesive, to interact and bond to each other. The protrusions are arranged in such a way to contain a wire, string, or heating element, within a receiving area. The arrangement of the protrusions allow for routing of the wire, string, or heating element in a variety of angles, bends, and other routing layouts.
