Wall Tie with Deformable Ribs for Hard Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall ties struggle to securely anchor hard insulation materials between inner and outer cavity walls, often causing installation difficulties and safety hazards due to their design, which is not suitable for relatively hard insulation panels.
Innovation Solution
A wall tie design featuring a plug with a longitudinal central bore and deformable ribs, along with a pin that can be anchored in the outer cavity wall, allows for easy and secure installation of hard insulation panels by forming a clamped fit with the inner cavity wall, using a pin with a screw thread and ribs that deform to engage firmly with the surrounding material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat first end part is used to anchor in the joint of an outer cavity wall, then the wall tie can be securely anchored, but it cannot easily cut through hard insulation materials and causes installation difficulties
Solution Approach 1:
The wall tie is divided into two separate components: a plug for anchoring in the inner cavity wall and a pin for anchoring in the outer cavity wall. The plug has a narrowed insertion end that can easily penetrate hard insulation materials, while the pin provides secure anchoring in the outer wall, thus resolving the contradiction between anchoring reliability and ease of installation.
Solution Approach 2:
Instead of using a single flat end part that tries to both anchor and penetrate, the invention inverts the approach by using a narrowed insertion end on the plug that is specifically designed to easily cut through hard insulation materials, while the anchoring function is handled by the pin in the outer wall.
2Strength
If the first end part is made wide for secure anchoring, then anchoring strength is improved, but it creates safety hazards for personnel during installation
Solution Approach 1:
By separating the wall tie into a plug and a pin, the narrowed insertion end of the plug eliminates the safety hazard of wide flat surfaces, while the pin provides the necessary anchoring strength in the outer wall, thus resolving the contradiction between anchoring strength and safety.
3Device complexity
If a single plug design is used for both soft and hard insulation materials, then device simplicity is maintained, but it cannot effectively support hard insulation panels
Solution Approach 1:
The wall tie is segmented into a plug with narrowed insertion end and a pin component. This segmentation allows the plug to effectively support hard insulation panels while maintaining relatively simple device structure, resolving the contradiction between device simplicity and support capability.
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 solution enables safe, simple, and effective anchoring of hard insulation materials between cavity walls, ensuring reliable installation and preventing displacement of the insulation material, thus addressing the limitations of prior wall tie designs.
Implementation Method 1
the ribs are (preferably elastically) deformed in such a manner that a clamped fit between the plug and the inner cavity wall is already realised
Implementation Method 2
the pin, which is for example provided with a screw thread, is turned or driven into the central bore of the plug

AI summary
A wall tie having a supporting function for an insulation material to be installed in a wall cavity, characterised in that the wall tie comprises a plug to be inserted through the insulation material and into the inner cavity wall, which plug comprises a pin-shaped body provided with a longitudinal, central bore, as well as a pin to be anchored in an outer cavity wall, which pin can be inserted into the bore in the plug body, which body is provided with outwardly extending, deformable, longitudinal ribs at least along part of its length, and which plug is capable of supporting the insulation material.
