Detachable Shelf Rail Power Supply for Flexible LED Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelving systems with LED lighting face issues of messy wires and limited versatility due to fixed power supply arrangements, making maintenance and aesthetics challenging, and restricting the ability to easily add or reposition lighting components.
Innovation Solution
A shelving system with detachable power supply apparatuses integrated into hollow metal vertical shelf rails, featuring bus bars and push-in resilient ball head plungers for secure and flexible power distribution, allowing arbitrary placement of power supplies along the rail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power source is provided on the back of the shelf with wires passing through to the LED lighting, then electrical connection is achieved, but wire clutter increases and maintenance becomes inconvenient
Solution Approach 1:
The power supply apparatus is extracted from the traditional fixed location on the shelf back and transformed into a detachable unit that can be independently positioned. The power supply is separated from the shelf structure itself, allowing it to be removed and repositioned without affecting the shelf or requiring wire routing through the shelf back.
Solution Approach 2:
The power supply apparatus transitions from a static, fixed installation to a dynamic, repositionable configuration. The detachable design with removable plugs and sockets enables the power supply to be moved to different locations along the shelf rail, adapting to changing lighting needs without permanent installation.
2Reliability
If the power supply is fixed on a support arm, then electrical connection is stable, but versatility is reduced and additional sockets cannot be used
Solution Approach 1:
The shelf rail is designed with multiple openings distributed along its length, each capable of receiving a power supply apparatus. This universal design allows any opening to serve as a power supply location, enabling the system to adapt to various lighting configurations and accommodate additional sockets without requiring specialized mounting positions.
Solution Approach 2:
The power supply system is segmented into independent, modular units that can be individually installed in different openings along the shelf rail. Each power supply apparatus with its plug and socket is a self-contained module that can be added, removed, or repositioned independently, providing flexibility while maintaining stable electrical connections.
3Power
If wires are passed through the shelf from front to back, then LED lighting is powered, but aesthetics deteriorate and maintenance becomes difficult
Solution Approach 1:
The power delivery system is extracted from the interior shelf structure and repositioned to the exterior front surface. The power supply apparatus mounts on the front of the shelf with the power cord accessible from the front, eliminating the need to route wires through the shelf back and improving both aesthetics and maintenance accessibility.
4Ease of manufacture
If the shelving system uses fixed power supply arrangement, then installation is simple, but adaptability to different lighting needs is limited
Solution Approach 1:
The system is divided into modular components: the shelf rail with multiple standardized openings, detachable power supply apparatus, and plug-socket connections. This segmentation allows for simple initial installation while enabling easy reconfiguration by moving individual power supply modules between openings, combining installation simplicity with long-term adaptability.

AI summary
A shelving system having a detached power supply apparatus includes at least a hollow vertical shelf rail (10), at least a bus bar (20) inserted into the vertical shelf rail, and at least a detached power supply apparatus (30) inserted in the vertical shelf rail and electrically connected to the bus bar. Each of the vertical shelf rails includes at least a punched hole (11), and two locating protrudes (12). Each of the bus bar includes a slot (211), and two current conductors (22). The slot includes a carrier surface, and a track abutting surface. Each of the detached power supply apparatus (30) passes through the punched hole (11) and is inserted between the carrier surface and the track abutting surface. Each of the detached power supply apparatus (30) includes two push-in resilient ball head plungers (32), a receiving surface, an abutting surface (311), and two reeds. The abutting surface is engaging with the track abutting surface.
