Wall Mounting Box With Pull-Out Insert For Prefab Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mounting boxes require significant on-site labor for cable pulling, connection, and installation, necessitating skilled personnel and increasing construction time and complexity.
Innovation Solution
A modular assembly comprising a mounting box, an insert part with a functional module, and a cover element that can be positioned in multiple stages, allowing cable connections to be made off-site, with the insert part moving from a building-in position to a use position for easy cover attachment, enabling prefabricated walls with integrated modules that can be easily assembled by untrained personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting boxes are used for building into walls with functional modules, then functional modules can be safely built into walls with cable connections realized in the mounting box, but a relatively large amount of work must be performed on site by skilled electricians including pulling cables, connecting cables, mounting the functional module, and attaching a cover frame
Solution Approach 1:
The patent applies preliminary action by pre-assembling the functional module within the mounting box at the factory before transportation to the construction site. The functional module is pre-mounted in a recess of the mounting box, and cable connections are pre-established, so that upon arrival at the site, only the mounting box needs to be installed into the wall opening without requiring complex on-site assembly work by skilled electricians
Solution Approach 2:
The mounting box is segmented into a main body with a recess and a separate functional module that fits into the recess. This segmentation allows the functional module to be pre-assembled in the factory and then easily installed as a complete unit at the construction site, reducing on-site work complexity while maintaining installation reliability
2Ease of operation
If functional modules are pre-mounted in mounting boxes at the factory, then on-site labor is reduced, but the mounting box must be opened and closed during transport and installation, exposing the functional module to dirt and damage
Solution Approach 1:
The functional module is nested within a recess of the mounting box, and the mounting box is further nested within a protective outer box. The outer box encloses the mounting box during transport, creating a nested structure that protects the functional module from dirt and damage while allowing easy handling and installation at the construction site
Solution Approach 2:
The outer box provides beforehand cushioning and protection for the mounting box and its contents during transport and storage. This protective enclosure prevents dirt, moisture, and physical damage from affecting the functional module before installation, eliminating the need to keep the mounting box open during transport
3Ease of operation
If the insert part protrudes through the mounting box for cover element attachment, then the cover element can be mounted on the insert part, but the open side of the mounting box cannot be closed off during building in, allowing dirt to enter
Solution Approach 1:
The functional module is pre-mounted in the recess of the mounting box at the factory, and the mounting box is enclosed in a protective outer box. This preliminary assembly allows the mounting box to be completely closed during transport and installation, preventing dirt entry, while still enabling cover element attachment at the construction site after the mounting box is installed in the wall opening

AI summary
The present invention provides an assembly for building into a wall, especially a prefabricated or prefab wall. The assembly comprises a mounting box (10), an insert part (20) mountable in the mounting box (10) and comprising a functional module (21) connectable with at least one cable (50). The assembly furthermore comprises a cover element (40) mountable on the insert part (20) after building the mounting box (10) into the wall. The mounting box (10) and the insert part (20) are adapted for being able to position the insert part (20) at least in a building-in position and a use position and for moving the insert part (20) from the building-in position to the use position. The assembly furthermore comprises a cover (30) for closing off an open side of the mounting box (10)in the building-in position of the insert part (20). The cover (30) is provided with a coupling means (31, 32) for coupling the cover (30) to the insert part (20), the coupling means (31, 32) being designed to pull the insert part (20) from the building-in position to the use position when removing the cover (30).
