Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for connecting electrical installation boxes with empty pipes in concrete construction lack flexibility and reliability, failing to provide efficient and secure attachment options.
Innovation Solution
An electrical installation box with a detachable wall area and parallel breaking strips allows for easy attachment of a pipe adapter, which can be pushed into the housing wall using cutting edges and a deflection area, enabling flexible and secure connection of empty pipes without pre-existing connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pipe adapters are attached to electrical installation boxes in concrete construction using existing solutions, then connection reliability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The wall area of the electrical installation box is segmented into a detachable wall area and a remaining area through predetermined breaking strips. This segmentation allows the pipe adapter to be attached by breaking off only the necessary wall portion, simplifying the attachment process while maintaining connection reliability without requiring complex adapter designs
Solution Approach 2:
The detachable wall area is extracted from the main housing wall through predetermined breaking strips. This extracted wall area serves as the connection interface for the pipe adapter, allowing reliable attachment while keeping the main housing structure intact and simple
2Reliability
If pipe adapters are attached to electrical installation boxes using existing solutions, then connection security is improved, but ease of operation deteriorates
Solution Approach 1:
The detachable wall area is pre-prepared with predetermined breaking strips that define the exact separation lines. This preliminary preparation allows the pipe adapter to be attached by simply breaking along these pre-defined lines, making the operation easy while ensuring secure connection through the properly positioned wall area
3Reliability
If force is applied to push pipe adapters into housing walls using existing solutions, then connection reliability is improved, but the required force increases
Solution Approach 1:
The housing wall is segmented into detachable and remaining areas, allowing the pipe adapter to be attached by breaking off only the necessary wall portion rather than forcing the adapter into the entire wall structure. This segmentation significantly reduces the insertion force required while maintaining connection reliability
Solution Approach 2:
The predetermined breaking strips are designed to break when force is applied, converting the potentially harmful excessive force into a beneficial separation action. The breaking strips fail in a controlled manner to create the detachable wall area, reducing the force needed for adapter attachment while ensuring reliable connection

AI summary
The invention relates to an arrangement comprising an electrical installation box (1) and a pipe adapter (2) connectable to the electrical installation box (1), particularly for installation in concrete, wherein the pipe adapter (2) has a pipe connection spigot (3) for connecting a conduit (4) and a joining area (5) with cutting edges (6) for connecting to the electrical installation box (1), the electrical installation box (1) has a housing (7) with several housing walls (8), a removable wall section (9) is provided in one housing wall (8), the removable wall section (9) is connected on two opposite sides to the adjacent areas of the housing wall (8) by means of parallel predetermined breaking strips (10), and the predetermined breaking strips (10) both extend to a common edge (11) of the housing wall (8), so that the pipe adapter (2) is in an orientation in which the pipe connection spigot (3) points away from the housing (7),Each of the two pre-scored break strips (10) can be attached to a common edge (11) of the housing wall (8) with a cutting edge (6). By removing the removable wall section (9) along the two pre-scored break strips (10), the section can be inserted into the housing wall (8) and thus connected to the electrical installation box (1). This provides a flexible and reliable solution for adapting electrical installation boxes with conduits.
