Solution Overview
Problem
Existing plug-in devices for goods display lack enhanced functionality and user comfort, particularly in terms of optical and visual presentation, and do not efficiently provide electrical supply for lighting or other loads.
Innovation Solution
A plug-in device with a socket and plug-in part that establishes a secure, electrically conductive connection via contact points on the socket and plug-in portion, allowing for the electrical supply of loads such as lighting, with anti-rotation safeguards and magnet mechanisms for increased retention, while maintaining a compact and protected design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plug-in device is designed with separate socket and plug-in part for goods display, then the device provides basic mechanical connection and positioning, but it lacks electrical supply functionality for lighting and other electrical loads
Solution Approach 1:
The plug-in device is designed to perform multiple functions: mechanical connection for positioning goods display components and electrical supply for lighting and other loads. The socket and plug-in part incorporate both mechanical engagement features and electrical contact points, allowing a single component to fulfill both mechanical and electrical functions simultaneously.
Solution Approach 2:
The electrical supply system is merged with the mechanical connection system. The contact points are integrated into the socket and plug-in part structures, so that the same components that provide mechanical connection also establish electrical contact. This combining eliminates the need for separate electrical connection mechanisms.
2Device complexity
If contact points are integrated into the lateral regions of the receptacle and plug-in portion, then electrical connection is achieved in a compact and protected design, but the contact points may be difficult to access for manufacturing and assembly
Solution Approach 1:
The contact points are pre-positioned and integrated into the lateral regions of the receptacle and plug-in portion during manufacturing. This preliminary integration ensures that the electrical connection features are already in place before final assembly, simplifying the overall manufacturing process despite the integrated design.
Solution Approach 2:
The lateral region integration allows the contact points to be automatically positioned and connected when the plug-in part is inserted into the socket. The mechanical insertion action itself brings the contact points into electrical contact, eliminating the need for separate electrical connection steps during assembly.
3Reliability
If anti-rotation safeguards and magnet mechanisms are added to increase retention, then the plug-in part has improved retention and positioning stability, but the device complexity increases
Solution Approach 1:
The anti-rotation safeguards and magnet mechanisms are integrated into the existing socket and plug-in part structures. The magnetic retention features are incorporated into the lateral regions alongside the contact points, and the anti-rotation elements are formed as part of the mechanical engagement structure, combining multiple functions into unified components.
Solution Approach 2:
Magnetic fields are used as an intermediary force to provide retention between the socket and plug-in part. The magnets create an attractive force that holds the components together without requiring direct mechanical contact for retention, supplementing the mechanical anti-rotation features and providing reliable positioning stability.

AI summary
A plug-in device for an arrangement for goods display, having a socket mounted on a supporting structure, and a plug-in part having a plug-in portion plugged into a receptacle of the socket. An electrification arrangement, in the connected state of the plug-in device electrically supplies electricity via the plug-in device, with an electrical connection being established via the socket and the plug-in part in that an electrically conducting contact is established by galvanic contacting between a first contact point and a second contact point. The first contact point is formed on the socket and the second contact point is formed on the plug-in portion such that, in the connected state, the first contact point in and the second contact point are electrically contacted with one another.
