Installation Box Cover Structure for Front Conduit Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional installation sockets require time-consuming assembly of electrical tubes before concrete is poured, and limited access often results in pipes being inserted too deep, requiring subsequent reduction.
Innovation Solution
An improved installation socket design featuring a cover, tubular intermediate piece, and base, which allows for easy insertion and secure attachment of electrical tubes, even in low installation space, by using a separable wall area and sealing lip for precise assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical conduits are inserted deeply into the installation box from the back, then the conduits are securely attached, but the installation time increases and subsequent shortening is required
Solution Approach 1:
The installation box is divided into a base body and a cover that can be separated. The cover is removable to provide access to the installation space from the front, allowing conduits to be inserted and secured without deep insertion from the back. This segmentation enables efficient conduit installation while maintaining secure attachment.
2Reliability
If the installation opening is closed during casting, then the installation box is protected, but access for conduit installation is limited
Solution Approach 1:
The installation box is segmented into a base body and a removable cover. The cover can be closed during concrete casting to protect the installation space, then removed later to provide full access for conduit installation from the front. This resolves the contradiction between protection during casting and accessibility during installation.
Solution Approach 2:
The cover transitions from a closed state during casting to an open/removed state during conduit installation. This dynamic behavior allows the installation box to adapt to different operational phases: protected during concrete pouring, then accessible for conduit work.
3Reliability
If conduits are inserted too deeply due to limited access, then secure attachment is achieved, but subsequent shortening from the front is required
Solution Approach 1:
By separating the installation box into a base body and removable cover, the design enables conduit insertion from the front at the optimal depth. The cover is removed to access the installation space, conduits are inserted to the correct depth with proper support, then the cover is replaced. This eliminates the need for subsequent conduit shortening.

AI summary
An electrical installation box (1) comprising a base (2) for mounting the installation box (1) to a formwork wall, a tubular intermediate piece (4) extending in an axial direction, and a cover (5). An installation opening (6) is provided in the base (2). The intermediate piece (4) is operatively connectable to the base (2) at a first end (8) and to the cover (5) at a second end (9). The cover (5) has at least one insertion opening (10) for inserting an electrical conduit into an installation space (7) of the installation box (1), wherein the at least one insertion opening (10) is closed in its initial state by a removable wall section (11), and, when the wall section (11) is removed and the cover (5) is operatively connected to the intermediate piece (4), at least partially connects to the intermediate piece (4).
