Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems for shelves, particularly in retail and logistics settings, face challenges with cluttered wiring, limited adaptability, and aesthetic issues due to exposed wiring, which complicates maintenance and versatility in rearranging or replacing shelf components.
Innovation Solution
An electrical supply support arm with an embedded plug system that includes a mounting base and fastener, allowing for adjustable distance between fastening surfaces, and a power taking contact assembly with rotatable contacts, integrated into a support arm body on a shelf column, enabling flexible installation and connection to power supply bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power supply is provided on the backlight surface of the shelf with wires threaded or wound from the exposed surface, then power can be supplied to LED lamps, but wiring becomes cluttered and maintenance becomes inconvenient
Solution Approach 1:
The patent extracts the power supply system from the traditional backlight surface location and relocates it to an independent support arm structure. The power supply box is separated from the shelf body, and wires are routed through the support arm's internal hollow cavity rather than being exposed on the shelf surface, thereby eliminating wiring clutter while maintaining power supply functionality.
Solution Approach 2:
The patent implements nesting by placing the power supply box inside the hollow cavity of the support arm. The wires are nested within the internal cavity of the support arm structure, and the entire power supply assembly is nested within the support arm, creating a compact integrated system that eliminates external wiring clutter.
2Ease of manufacture
If shelves are designed with fixed layer board positions to simplify structure, then manufacturing is easier, but versatility for different goods placement is reduced
Solution Approach 1:
The patent applies dynamics by making the layer board positions adjustable rather than fixed. The support arm structure includes movable components that allow layer boards to be repositioned along the support arm's length, enabling the shelf to adapt to different storage needs while maintaining a simple overall structure.
Solution Approach 2:
The patent segments the shelf structure into modular components: the main shelf body, independent support arms, and adjustable layer boards. This segmentation allows each component to be manufactured separately with simple structures, then assembled in various configurations to achieve versatility for different goods placement requirements.
3Reliability
If exposed wiring is used to connect power supply to LED lamps, then electrical connection is achieved, but aesthetics are compromised and product irradiation effect is affected
Solution Approach 1:
The patent hides the wires within the hollow cavity of the support arm structure, nesting the electrical connections inside the support arm rather than exposing them on the shelf surface. This maintains reliable electrical connection while eliminating the aesthetic problems of exposed wiring and preserving the product irradiation effect.
Solution Approach 2:
The patent extracts the wiring from the visible shelf surface and relocates it to the internal cavity of the support arm. The power supply box is also extracted from the backlight surface location and placed in the support arm, thereby removing all electrical components from the visible areas while maintaining their functional connections.
4Adaptability or versatility
If power supply components are integrated into the support arm structure, then adaptability to different support arm thicknesses is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal embedded plug system that can accommodate different support arm thicknesses. The plug structure includes adjustable components and standardized interfaces that allow the same power supply assembly to be installed on support arms of varying dimensions, achieving multi-functionality without requiring multiple specialized designs.
