Adjustable Insulation Fastener with Notched Rod and Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for thermal and sound insulating materials on building partitions or walls lack sufficient adjustability and shock resistance, particularly when used with varying thicknesses of insulating materials, and often require complex mechanisms for spacing adjustment.
Innovation Solution
A device comprising a first part with a notched rod and a third part with an internally notched tube, allowing for adjustable spacing and secure clipping, with features like annular grooves, resilient tabs, and radial fins for axial and rotational locking, enabling easy adaptation to different insulating material thicknesses and providing robust fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing fastening devices are used with varying thicknesses of insulating materials, then the device can be applied to different building requirements, but the spacing adjustment capacity is very limited and requires complex mechanisms
Solution Approach 1:
The fastening device incorporates a dynamic spacing adjustment mechanism where the distance between the two furring profiles can be varied continuously. The device allows adjustment of the spacing between support elements to accommodate different insulating material thicknesses, transforming a static fastening system into a dynamic one that adapts to varying installation requirements without requiring multiple specialized components.
2Reliability
If existing fastening devices are used, then fixation is provided, but the resistance to shocks is insufficient particularly when facing is installed
Solution Approach 1:
The fastening device incorporates shock-absorbing elements and flexible connection components that are built into the structure before installation. The device includes features such as elastomeric elements and adjustable spacing mechanisms that provide cushioning against shocks and impacts that may occur during or after installation, protecting the rigid facing material from damage while maintaining secure fixation.
3Ease of operation
If intermediate fastening devices pass through insulating material, then the two series of supports can be fixed, but the installation simplicity is compromised and adaptation to thickness range is limited
Solution Approach 1:
The fastening device is designed as a universal system that can accommodate a wide range of insulating material thicknesses through adjustable components. The device incorporates elements that can be configured for different spacing requirements, allowing a single fastening solution to serve multiple thickness ranges rather than requiring specialized devices for each thickness category, thereby simplifying installation while maintaining versatility.
4Reliability
If notched rod and tube with serrations are used, then sliding and immobilization can be achieved, but the practical operation is difficult requiring keys or levers
Solution Approach 1:
The fastening device incorporates self-aligning and self-locking features that eliminate the need for external tools or complex manipulation during assembly. The notched rod and tube design includes inherent guidance elements and engagement mechanisms that automatically align and secure the components in the correct position during installation, making the assembly process intuitive and tool-free while maintaining reliable locking.
