Solution Overview
Problem
Existing electrical installation systems in industrial settings face inefficiencies in production and installation due to the need for numerous screw connections, which increases time and complexity, and there is a challenge in ensuring the permanent functionality and safety of these connections.
Innovation Solution
A closed system of interconnected chamber modules with polygonal shapes, featuring lowered overlapping edges and vertical through holes for fasteners, eliminating the need for threaded holes and incorporating resilient grommets for cable protection, uses screws and nuts for connection and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections with threaded holes are used to connect modules, then the connection strength and reliability are improved, but the manufacturing complexity and assembly time increase
Solution Approach 1:
The patent extracts the threading operation from the module housing and relocates it to separate connection elements (screws and nuts). The module housing itself becomes simpler without threaded holes, while the connection functionality is provided by external fasteners that have the threading feature. This separation reduces manufacturing complexity of the main module while maintaining connection reliability.
Solution Approach 2:
The patent introduces connection elements (screws and nuts) as intermediary components between modules. These intermediaries provide the threading and fastening function without requiring the module housing to have complex threaded holes. The lowered edges serve as positioning intermediaries that guide the connection elements into proper alignment.
2Reliability
If multiple screw connections are used to ensure permanent functionality, then operational reliability is improved, but assembly time and production cost increase
Solution Approach 1:
The patent incorporates lowered edges on the module housing that serve as pre-positioning features. These lowered edges are formed during module manufacturing, so that during assembly, the connection elements automatically align and engage with the lowered edges without requiring complex alignment procedures. This preliminary positioning action significantly reduces assembly time while maintaining reliable connections.
3Ease of operation
If threaded holes are provided in module housings for connections, then connection functionality is improved, but manufacturing simplicity deteriorates
Solution Approach 1:
The patent removes the threading feature from the module housing and places it only in the separate connection elements (screws and nuts). The module housing is manufactured without threaded holes, simplifying the manufacturing process. The threading functionality is extracted and embodied in the connection elements that are manufactured separately and assembled later.
4Ease of operation
If lowered overlapping edges are used for module connection, then assembly simplicity is improved, but connection strength may be reduced
Solution Approach 1:
The patent combines multiple functions into the lowered edges: they serve as positioning features, alignment guides, and structural support elements. The lowered edges are integrated into the module housing design and work together with the connection elements (screws and nuts) to provide both simple assembly and strong mechanical connection. The overlapping configuration of lowered edges from adjacent modules creates a distributed strength system.

AI summary
The closed system for placing installations is formed by interconnected chamber modules (1, 2, 3, 4, 5) of a rectangular top view, In the connection area, the adjacent modules (1,2,3,4,5) are provided with lowered edges which overlap, and in the overlap area vertical through holes (9) are provided for module (1,2,3,4,5) fasteners. The fasteners consist of screws (11) and nuts (12). The lowered edges are provided in the horizontal abutting surfaces with horizontal coaxial passages (10). These passages (10) connect the chambers (6) of adjacent modules (1,2,3,4,5) and cables pass through them. The passages (10) are provided with a sealing grommet (13) which is made of a resilient material. The chamber modules (1,2,3,4,5) consist of two caps (7, 8) attached to each other.
