Underlayment Boss Structure for Secure Heating Wire Positioning
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 heat regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wires are not secured between adjacent studs, then installation is simpler, but heating becomes uneven and wires may be damaged
Solution Approach 1:
The continuous mat is segmented into discrete sections with individual studs, allowing wires to be secured at specific intervals between studs rather than requiring continuous attachment, thus simplifying installation while maintaining heating uniformity
Solution Approach 2:
Studs are pre-positioned on the mat at predetermined locations before wire installation, allowing installers to simply place wires between studs without complex measurement or positioning, achieving both simplicity and reliability
2Ease of operation
If a continuous mat is used, then wire positioning is facilitated, but successive layers of adhesive cannot interact with each other
Solution Approach 1:
The continuous mat is replaced with a segmented structure featuring discrete studs on a base, creating gaps between studs that allow adhesive layers to interact while still providing predetermined wire positioning locations
Solution Approach 2:
The base structure with studs acts as an intermediary element that provides wire positioning functionality while simultaneously allowing adhesive penetration and interaction between flooring layers
3Loss of energy
If thicker pipes are used in hydronic systems, then heat transfer is improved, but floor thickness increases which is undesirable
Solution Approach 1:
The mechanical hydronic pipe system is replaced with an electric heating cable system that can be installed in a much thinner configuration while achieving comparable or superior heat transfer efficiency
Solution Approach 2:
The heating system parameters are changed from hydraulic (pipe diameter, water flow) to electrical (cable resistance, current), enabling much thinner installation depth while maintaining or improving heat transfer efficiency

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.
