Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switching and/or distributing devices require significant time and specialized knowledge for component arrangement and exchange, especially in potentially explosive atmospheres, with limited flexibility in accommodating different numbers and sizes of components.
Innovation Solution
The solution involves power distribution rails connected to sub-distribution rails that extend in parallel planes, allowing for modular arrangement of components with electrical contact, enabling easy installation and exchange of components without screws, and using a separating plate for mechanical and electrical connection, ensuring electrical insulation and explosion protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are screwed or wired to power distribution rails in conventional switching devices, then reliable electrical connection is achieved, but the arrangement requires relatively large time and specific knowledge about work in potentially explosive atmospheres
Solution Approach 1:
The device is segmented into modular components that can be independently arranged and connected. The housing is divided into a receiving housing and a housing cover, with components that can be separately assembled and detached without requiring complex wiring operations in explosive atmospheres.
Solution Approach 2:
The conventional mechanical screwing and wiring operations are replaced by a simplified mechanical connection system. Components are detachably connected to power distribution rails through a mechanical interface that ensures reliable electrical contact without requiring threading or complex assembly procedures.
2Reliability
If components are screwed or wired to power distribution rails in conventional switching devices, then reliable electrical connection is achieved, but specific knowledge about work in potentially explosive atmospheres is required
Solution Approach 1:
The system is designed to be self-explanatory and self-assembly friendly. The modular components and standardized interfaces allow users to arrange and connect components intuitively without requiring specialized knowledge about working in potentially explosive atmospheres, while still maintaining safety and reliability.
Solution Approach 2:
The power distribution rails and component interfaces are designed with universal compatibility. The same standardized connection mechanism works for all components regardless of the specific application environment, eliminating the need for specialized procedures in explosive atmospheres while ensuring reliable electrical connections.
3Ease of manufacture
If the arrangement of components is predetermined in conventional switching devices, then manufacturing simplicity is maintained, but few possible variations for arranging a different number or components of different sizes are possible
Solution Approach 1:
The component arrangement system transitions from a static, predetermined layout to a dynamic, reconfigurable system. The modular housing with standardized power distribution rails allows components to be freely positioned and rearranged according to different numbers and sizes, while the standardized interfaces maintain manufacturing simplicity through repetition and modularity.
Solution Approach 2:
The system adds spatial flexibility by allowing components to be arranged in multiple dimensions and configurations within the housing. The power distribution rails extend to accommodate components of different sizes and numbers, enabling versatile arrangements while maintaining a standardized base structure that preserves manufacturing simplicity.

AI summary
A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and are connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and are electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, are in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.
