Solution Overview
Problem
In industrial automation, the connection of safety switching devices is often prone to wiring errors, is time-consuming to install, and poses failure risks due to loose cables or wire contact issues, requiring frequent maintenance.
Innovation Solution
A connection system comprising interlocking modules that establish direct electrical and mechanical connections between devices, eliminating the need for individual wiring, allowing for easy replacement of devices without removing others, and accommodating devices on a top-hat rail or wall with a 120 mm row pitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual wiring is used to connect devices, then electrical connections can be established between devices, but installation time increases and wiring errors occur
Solution Approach 1:
The connection system is divided into modular connection modules, each capable of independently establishing electrical connections. Instead of individual wiring between devices, multiple connection points are segmented into discrete modules that can be individually installed and connected, reducing installation complexity and time while maintaining reliability
Solution Approach 2:
Connection modules serve as intermediary components between devices, eliminating the need for direct individual wiring. The modules provide standardized connection interfaces that simplify the connection process, reduce wiring errors, and enable faster installation while maintaining reliable electrical connections
2Reliability
If individual wiring is used to connect devices, then electrical connections can be established, but maintenance requirements increase due to loose cables and wire contact issues
Solution Approach 1:
By segmenting the connection system into modular units, each connection module can be independently maintained and replaced. This eliminates the need to troubleshoot and repair individual wire connections throughout the system, significantly reducing maintenance frequency and improving connection stability
Solution Approach 2:
The connection modules act as protected intermediaries that shield internal electrical connections from environmental factors causing loose cables and wire contact issues. The modular design allows these protected connections to be maintained less frequently while ensuring stable electrical connections
3Adaptability or versatility
If devices are connected using traditional wiring methods, then electrical connections can be established, but the system lacks flexibility for device replacement and expansion
Solution Approach 1:
The connection system is segmented into standardized modular units with uniform interfaces. This segmentation enables devices to be replaced or expanded by simply connecting or disconnecting modules, providing high flexibility without increasing overall system complexity
Solution Approach 2:
The connection modules are designed with universal interfaces that can accommodate different devices and connection configurations. This universality allows the same module design to serve multiple functions and device types, enhancing adaptability while maintaining simple, standardized connection procedures

AI summary
A connection system includes a first connection module and a second connection module, which each have a first connection devices, the first connection module including a second connection device and the second connection module including a third connection device. There is a direct electrical connection between the first connection device of the connection module and the accommodated device and a direct mechanical connection between the connection module and the accommodated device. The first connection module can be locked directly to the third connection device such that the first connection module is electrically and mechanically connected to the second connection module. The third connection device is arranged such that, when the second connection device is locked to the third connection device, mechanical and electrical disconnection of the first connection module from the second connection module is prevented if the second connection module has received a device.
