Cavity Wall Box Mounting Elements with Releasable Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cavity wall boxes with contact elements face challenges in easy production, assembly, and alignment due to the need for film hinges that require severing and can leave residues, making it difficult to precisely align multiple boxes and connect them securely.
Innovation Solution
The use of releasable connecting elements, such as sliding guide elements and counter-elements, allows for easy attachment and detachment of contact elements to the cavity wall box, enabling precise alignment and connection, with features like dovetail guides and springs for secure engagement and interference fits, facilitating the connection of multiple boxes and contact elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact elements are connected to the cavity wall box by means of a film hinge, then the contact elements can be folded up against the cavity wall box during installation, but the film hinge must be severed with a knife which leaves a residue forming a burr that prevents precise alignment of multiple cavity wall boxes
Solution Approach 1:
The film hinge connection is replaced by separate connecting elements that attach contact elements to the cavity wall box. These connecting elements can be removed without leaving residues, enabling precise alignment when multiple boxes are connected. The segmentation separates the hinge function from the mounting structure, allowing clean detachment and repositioning.
2Adaptability or versatility
If straight wall sections of the cavity wall box are required to connect multiple boxes, then contact elements must be removed by severing the film hinge, but this creates an additional work step and leaves residues that prevent exact alignment
Solution Approach 1:
The connecting elements are designed to be dynamically attachable and detachable without damage. This allows the contact elements to be easily removed and repositioned when connecting multiple cavity wall boxes in different configurations, eliminating the need to sever film hinges and perform additional cleanup work steps.
3Ease of manufacture
If releasable connecting elements are used instead of film hinges, then contact elements can be easily attached and detached without severing, but additional connecting elements and structures are required
Solution Approach 1:
The connecting elements integrate multiple functions into a single component: they provide mechanical attachment, enable precise positioning, and allow easy detachment. By merging the attachment mechanism and alignment features into unified connecting elements, the overall structure remains simple despite the enhanced functionality.

AI summary
The invention relates to a cavity wall box with mounting elements associated with the cavity wall box for installation in a wall recess of a cavity wall, wherein a box interior is bounded by a box wall, wherein the box wall has first wall sections and second wall sections extending along the circumferential direction of the cavity wall box, wherein one or more outwardly directed mounting sections with contact surfaces are arranged on a second wall section along the circumferential direction of the cavity wall box, wherein the mounting elements each have a curved outer surface and, opposite the outer surface, a buttress surface for contact with a mounting section on the box wall of the cavity wall box, and wherein one or more first connecting elements are arranged in the area of the mounting sections of the cavity wall box.It is provided that one or more second connecting elements are arranged on the abutting surfaces of the mounting elements, and that the connecting elements are designed to detachably connect the mounting elements to the cavity wall box. The cavity wall box according to the invention can be easily combined with one another and adapted to the shape of a wall opening.
