Cavity Wall Installation Box With Barb Anchoring and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing installation boxes for electrical installations in cavity walls are complex to install and often fail to achieve a secure fit, especially in multi-layer or thin cavity walls.
Innovation Solution
An installation box design featuring anchoring elements that form a barb in the wall for secure attachment, combined with a sealing system using soft-elastic plastics to ensure a reliable fit and easy assembly, including a distribution of anchoring elements and clamping ribs for universal application across different wall types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional holding devices with adjusting screws are used to secure the installation box, then the installation box can be fastened to the wall, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the adjustment mechanism from the fastening system by using pre-configured anchoring elements with integrated deformation zones that automatically engage with the wall structure, eliminating the need for separate adjusting screws and complex manual assembly steps
Solution Approach 2:
The anchoring elements perform self-adjustment through their deformation zones that automatically adapt to the wall thickness and material during insertion, providing secure fastening without requiring manual adjustment or complex tooling
2Reliability
If conventional holding devices are used to secure the installation box, then fastening is achieved, but the installation time increases due to complex assembly steps
Solution Approach 1:
The anchoring elements are segmented into multiple rows with different densities, allowing simultaneous engagement with different wall structures during a single insertion action, thereby achieving secure fastening without repetitive adjustment steps
Solution Approach 2:
The anchoring elements are pre-configured with deformation zones and barb structures that automatically engage and lock into the wall structure upon insertion, eliminating the need for post-installation adjustment and reducing total installation time
3Adaptability or versatility
If the installation box is designed for universal application in different cavity walls, then adaptability improves, but the secure fit becomes difficult to achieve in all wall types
Solution Approach 1:
Different rows of anchoring elements have locally optimized properties: first rows have higher density for initial engagement, while subsequent rows have lower density for deeper penetration, with varying barb orientations that adapt to different wall materials and thicknesses
Solution Approach 2:
The anchoring elements incorporate deformation zones that allow dynamic adaptation during insertion, enabling the same anchoring element design to securely engage with various wall types (plasterboard, wood, composite) by automatically deforming to match the specific wall structure
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 design allows for easy and quick assembly with enhanced sealing and secure fastening, ensuring the installation box remains firmly in place across various cavity wall configurations, improving both installation ease and durability.
Implementation Method 1
The anchoring elements are designed such that the force required to insert the installation box into the wall opening is lower than the force required to remove the installation box from the wall opening
Implementation Method 2
at least one seal running along the side wall for sealing the box body with respect to the wall opening

AI summary
The invention relates to an installation box (1) for electrical installations, comprising a box body (2) made of a first plastic. The box body includes a base (3) which transitions into a tubular side wall (4) extending in the axial direction (z) and surrounding an installation space (6), and an installation opening (5) which is arranged opposite the base (3) and is bounded by a radially outwardly projecting edge (7) of the side wall (4). The installation box further comprises one or more anchoring elements (9) arranged near the edge (7), projecting from the outer surface (8) of the side wall (4) and distributed around the circumference of the side wall (4) for securing the installation box (1) in a wall opening, and at least one seal (10) for sealing the box body (2) against the wall opening.
