Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating wall systems face challenges in accommodating thick insulation layers due to limitations in screw length and the need to minimize penetrations through the insulation, which affects the insulating effect and ease of installation.
Innovation Solution
A wall system that utilizes frictional forces between the insulation material and the walls, achieved by compressing the insulation material to create pre-stressed mounting, allowing for thicker insulation layers with fewer components and reduced thermal bridging, using screws with standardized tension and a rough surface structure to enhance friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to penetrate the insulation material to secure the support members, then the support members can be firmly attached to the first wall, but the insulating effect is reduced due to thermal bridges created by the screw penetrations
Solution Approach 1:
The patent replaces the mechanical penetration system (screws passing through insulation) with a friction-based mechanical system. The support members are compressed against the first wall by pre-stressed insulation material, creating friction forces that secure the attachment without penetrating the insulation material, thereby eliminating thermal bridges while maintaining attachment strength.
Solution Approach 2:
The insulation material serves as an intermediary element that transfers the attachment function from direct mechanical penetration to indirect friction-based attachment. By compressing the insulation material between the support members and the first wall, it creates the necessary friction forces while remaining intact and non-penetrated, thus preventing thermal bridging.
2Object-affected harmful factors
If the insulation layer is made thicker to meet modern insulation requirements, then the insulating effect is improved, but it becomes difficult to design suitable screws that can penetrate and properly fasten to the inner wall
Solution Approach 1:
The patent replaces the penetration-based mechanical system with a compression-based friction system. Instead of using long screws that penetrate through thick insulation layers, the support members are secured by compressing the insulation material to generate sufficient friction forces, eliminating the need for penetration and simplifying installation for thick insulation layers.
Solution Approach 2:
The patent changes the mechanical parameter from penetration depth to compression force. By applying a predetermined compression force to the insulation material (between 1.2% and 3.2% compression), the system generates adequate friction forces to secure support members without requiring screw penetration, making the system adaptable to various insulation thicknesses.
3Object-affected harmful factors
If the number of screw penetrations through the insulation is reduced to maintain insulating effect, then thermal bridging is minimized, but the attachment reliability may be compromised
Solution Approach 1:
The patent replaces the penetration-based attachment mechanism with a friction-based mechanism. The friction forces generated by compressing the insulation material between the support members and the first wall provide sufficient attachment reliability without requiring screw penetrations, thus maintaining insulating effect while ensuring secure attachment.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical interpenetration to friction-based holding. By optimizing the compression force applied to the insulation material, the system generates adequate friction forces to reliably secure support members without penetration, balancing attachment reliability with insulation effectiveness.
4Object-affected harmful factors
If adhesive is used to attach insulation material to the wall surface, then the number of penetrating screws is reduced, but this solution is not suitable for wall systems requiring relatively thick insulation layers
Solution Approach 1:
The patent replaces both adhesive attachment and screw penetration with a compression-based friction system. The support members are secured by compressing the insulation material to generate friction forces, which works effectively for thick insulation layers where adhesive would be insufficient and screw penetration would create excessive thermal bridges.
Solution Approach 2:
The patent changes the attachment mechanism from surface-level adhesive bonding to volume-based compression friction. By applying compression force throughout the thickness of the insulation material, the system generates sufficient friction forces even for thick insulation layers, making it adaptable and versatile for various insulation thicknesses.
