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 a hot water storage tank, which is less efficient than electric systems.

Innovation Solution

The underlayment features protrusions forming routing hubs with receiving cavities to securely route and contain heating elements, allowing for efficient routing and reducing thermal loss, and includes a pad layer for additional support and insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wires are placed between studs without securing mechanisms, then installation is simpler, but wire separation occurs causing uneven heating and wire damage

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

Solution Approach 1:

The underlayment is divided into modular sections with individual protrusions at regular intervals. Each protrusion acts as an independent wire positioning element, allowing wires to be securely routed between studs without requiring continuous securing mechanisms. This segmentation maintains installation simplicity while ensuring reliable wire positioning at multiple discrete points along the heating element length.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Protrusions extend from the underlayment to serve as intermediary elements between the underlayment structure and the heating wires. These protrusions provide a physical interface that guides and secures wires in the correct position without requiring direct attachment to studs or complex fastening systems, thus maintaining ease of installation while ensuring wire stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

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

Engineering Contradiction:
Improveinstallation speedVSAvoidadhesive layer interaction
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The continuous mat is replaced with a segmented underlayment structure featuring discrete protrusions at regular intervals. This segmentation allows adhesive to be applied in multiple layers that can interact with different protrusions and the substrate, enabling mechanical interlocking between layers while maintaining efficient installation through the pre-formed modular structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The underlayment structure adds vertical dimensionality with protrusions extending upward from the mat surface. This three-dimensional structure allows subsequent adhesive layers to bond to the protrusions and previous layers, creating a multi-layered bonded assembly that maintains installation speed while enabling proper adhesive interaction between layers.

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

3Power

If hydronic system with storage tank is used, then heating capacity is sufficient, but thermal efficiency decreases due to heat loss

Engineering Contradiction:
Improveheating capacityVSAvoidthermal loss
Core Design Contradiction:
PowerVSLoss of energy

Solution Approach 1:

The heating element and associated underlayment system are extracted as a separate, pre-configured module that can be installed directly onto the subfloor. This extraction eliminates the need for bulky storage tanks and complex piping infrastructure, providing sufficient heating capacity through efficient electric heating elements while minimizing thermal loss through direct coupling to the flooring structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical hydronic system with water circulation and storage tanks is replaced with an electric heating system that converts electrical energy directly to thermal energy. This substitution eliminates the thermal losses associated with water circulation, storage tank heat loss, and pump energy consumption, while maintaining sufficient heating capacity through high-efficiency electric heating elements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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.
