Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface heating/cooling systems, particularly underfloor heating, face issues with holding forces and damage to insulation boards due to conventional fastening methods that pierce or damage the insulation structure during pipe installation.
Innovation Solution
A laying system comprising a structural chamber panel with three functional layers and wire pipe holders with laterally bent ends, where the radius of curvature matches the panel thickness and setting tool height, ensuring maximum holding force without damaging the insulation board, and a setting tool with adjustable restraint system for consistent fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fastening methods (staples, cramps) are used to attach pipes to insulation boards, then pipes can be secured to the surface, but the insulation board structure is damaged during the fastening process
Solution Approach 1:
The fastening system is divided into separate functional components: the pipe holder with laterally bent ends provides the fastening function, while the insulation board maintains its integrity. The setting tool is another separate component that enables controlled installation. This segmentation allows each component to perform its function without compromising the insulation board structure.
Solution Approach 2:
The setting tool acts as an intermediary device that mediates between the pipe holder and the insulation board. It controls the introduction process, ensuring that the laterally bent ends are properly formed and positioned without excessive force that would damage the insulation board. The setting tool translates operator input into precise fastening action.
2Strength
If wire pipe holders with laterally bent ends are used, then holding forces are improved, but the radius of curvature must be precisely matched to panel thickness to avoid damage
Solution Approach 1:
The radius of curvature of the laterally bent ends is specifically designed and controlled during manufacturing to match the panel thickness. This parameter optimization ensures that when the pipe holder is introduced, the bends engage the pipe and panel at the correct depth and angle, maximizing holding force while preventing penetration through the lower layer. The setting tool's counter-holder height is also designed to correspond to this radius.
Solution Approach 2:
The laterally bent ends are pre-formed during pipe holder manufacturing with the precise radius of curvature required. This preliminary preparation ensures that during installation, no additional forming or bending is needed that could compromise the insulation board. The geometry is optimized in advance to achieve the desired fastening effect.
3Strength
If the setting tool introduces pipe holders with excessive force, then secure attachment is achieved, but the lower insulation layer is penetrated
Solution Approach 1:
The setting tool with its counter-holder serves as a mediator that controls the introduction process. The counter-holder's height corresponds to the radius of curvature of the pipe holder bends, ensuring that the bends are formed and positioned at the correct depth. This intermediary mechanism prevents excessive force or depth that would penetrate the lower insulation layer while still achieving secure attachment.
Solution Approach 2:
The setting tool is designed with specific geometric parameters - the counter-holder height matches the radius of curvature of the pipe holder bends. This parameter matching ensures that during introduction, the bends engage the pipe and panel at the optimal depth and angle, achieving maximum holding force without penetrating through the lower layer.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances holding forces while minimizing damage to the insulation board, ensuring secure pipe attachment and preventing penetration through the lower layer, thus maintaining insulation integrity and thermal efficiency.
Implementation Method 1
The laterally bent ends of the pipe holders have a radius of curvature r, which is equal to or smaller than the height of the upper cover layer and the middle layer of the installation board plus the construction height of the counter holder of the setting tool
Implementation Method 2
the insertion process for the fastening means designed according to the invention is characterized in that the leg ends, which are executed in a circular arc whose radius matches the maximum permissible penetration depth, are introduced into the installation panel by a pivoting bending process on the fastening means themselves
Implementation Method 3
the setting tool is designed to accommodate the pipe holders with laterally bent ends with swivel arches and to introduce the same into the laying board
