Tensioning Mounting Sleeve for Universal Wall Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting solutions for flush-mounted boxes in walls are complex and limited to specific wall thickness ranges, making them difficult to manufacture, assemble, and reuse across different types of walls.
Innovation Solution
A mounting sleeve design featuring a first sleeve with a flange and a displaceable second sleeve, along with a tensioning element and clamping elements that can be tensioned radially and axially to securely attach to any wall type, allowing for easy installation and removal without damaging the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex flush-mounted box with screw-adjustable lugs and wings is used to clamp the wall, then the mounting can be secured, but the device complexity increases and it is limited to a specific wall thickness range
Solution Approach 1:
The mounting sleeve is divided into two separate sleeves (first sleeve and second sleeve) that can be independently positioned and tensioned. The first sleeve has clamping elements for radial clamping while the second sleeve has clamping elements for axial clamping, allowing each component to perform a specific function rather than requiring a complex integrated structure with multiple adjustable parts.
Solution Approach 2:
The mounting sleeve design provides universal applicability across different wall types and thicknesses through the combination of radial and axial clamping elements. The first sleeve with radially protruding clamping elements can clamp various wall materials, while the second sleeve with axially protruding clamping elements accommodates different wall thicknesses, making the system universally applicable without requiring model-specific adjustments.
2Reliability
If a flush-mounted box designed for limited wall thickness range is used, then the mounting can be secured, but the adaptability to different wall types is reduced
Solution Approach 1:
Different portions of the mounting sleeve have different clamping characteristics tailored to specific needs. The first sleeve has clamping elements designed for radial clamping of the wall material, while the second sleeve has clamping elements designed for axial clamping to accommodate wall thickness variations. This local differentiation of clamping functions allows the system to adapt to various wall types and thicknesses while maintaining secure mounting.
3Reliability
If a mounting system requiring multiple screw-adjustable lugs and wings is used, then the mounting can be secured, but the ease of manufacture and assembly is reduced
Solution Approach 1:
The functionality of multiple screw-adjustable lugs and wings is merged into a simplified two-sleeve structure. The first sleeve integrates the radial clamping function that previously required multiple lugs and wings, while the second sleeve integrates the axial positioning function. This merging reduces the number of separate components and simplifies both manufacturing and assembly processes while maintaining mounting security.
4Reliability
If a complex mounting structure with multiple components is used, then the mounting can be secured, but the ease of operation for installation and removal is reduced
Solution Approach 1:
The mounting sleeve employs dynamic tensioning elements that can be easily adjusted during installation and released during removal. The tensioning elements allow the two sleeves to be moved relative to each other, enabling the clamping elements to engage and disengage from the wall smoothly. This dynamic design facilitates easy installation and removal operations while maintaining secure mounting during use.

AI summary
A mounting sleeve for mounting in a recess in a wall having a first sleeve with a longitudinal axis, wherein a flange is arranged in the region of a first free end of the first sleeve, the flange projects radially outwards beyond the circumference of the sleeve-shaped body as a result that can abut against an outside of the wall, wherein the mounting sleeve has a second sleeve that is arranged displaceably along the longitudinal axis in the first sleeve and the mounting sleeve has a tensioning element which the two sleeves can be brought from a non-tensioned position into a tensioned position, wherein the first sleeve and/or the second sleeve has at least one clamping element which, in the tensioned position, projects radially outwards beyond the circumference of the body of the first sleeve, as a result of tensioning of the mounting sleeve with the wall can be achieved.
