Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-floor heating systems face challenges in securely locating and maintaining 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 and maintain heating elements, allowing for adhesive interaction between layers and facilitating even heat distribution, with features like ring-shaped bosses and hollow structures for weight reduction and improved heat retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires or pipes are not securely located in heating systems, then installation is simpler, but heating becomes uneven and wires may be damaged
Solution Approach 1:
The base is segmented into multiple protrusions (bosses) that are distributed across the surface. Each protrusion independently secures a wire or pipe at a specific location, dividing the securing function into multiple discrete points rather than requiring a continuous complex structure. This segmentation achieves reliable wire positioning while keeping the overall structure simple.
Solution Approach 2:
The protrusions act as intermediary elements between the base and the wires/pipes. Instead of directly complexly securing wires to the base, the protrusions serve as intermediate positioning features that guide and hold the wires in place, simplifying the overall securing mechanism while ensuring proper wire placement for uniform heating.
2Strength
If successive layers of adhesive are used to bond flooring layers, then bonding strength increases, but adhesive layers cannot interact with each other reducing cohesion
Solution Approach 1:
The protrusions create a porous or interconnected structure that allows adhesive to flow through and interact between successive adhesive layers. The spaces around and between protrusions enable adhesive penetration, allowing chemical bonding across multiple layers rather than just surface bonding, thus achieving both strong bonding and layer cohesion.
Solution Approach 2:
The invention replaces purely mechanical adhesive bonding (surface-to-surface contact) with a system where adhesive can chemically interact through the protrusion structure. Instead of relying only on mechanical interlocking of adhesive layers, the protrusions enable adhesive penetration and chemical bonding across layers, strengthening the overall bond while maintaining layer interaction.
3Loss of energy
If thick pipes are used in hydronic systems, then heat transfer is effective, but floor thickness increases which is undesirable
Solution Approach 1:
Instead of using thick pipes throughout, the invention uses localized protrusions at specific positions to secure thin pipes. The protrusions concentrate the structural support function at discrete locations, allowing the use of thinner pipes that would otherwise be too flexible, while maintaining effective heat transfer at the localized contact points between pipes and flooring.
Solution Approach 2:
The invention moves the support function from a vertical dimension (thick pipes providing structural rigidity) to a horizontal dimension (protrusions providing localized support). By securing thin pipes at multiple elevated points through protrusions, the system achieves the necessary structural stability without increasing pipe thickness or floor buildup, maintaining effective heat transfer with minimal floor thickness.

AI summary
An underlayment system includes a plurality of bosses that emanate from 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.
