Frame construction for a rack system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelving system frame constructions are not easily assembled with specified equidistant heights for horizontal traverses, lacking a straightforward method to achieve consistent and adjustable configurations.
Innovation Solution
A frame construction using column and traverse hollow profiles combined with special traverse connectors, including a perforated grid strip housed in the hollow column profile, allowing traverses to be positioned at defined height intervals with a detachable and adjustable connection system, and optionally incorporating LED lighting for ambient illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional frame constructions are used, then structural stability is achieved, but assembly ease and adjustment flexibility are reduced
Solution Approach 1:
The frame construction is divided into modular components: hollow column profiles, hollow traverse profiles, and separate connector elements. This segmentation allows each component to be manufactured independently and assembled through simple insertion and clipping operations, greatly improving assembly ease while maintaining structural integrity through the standardized modular interface.
Solution Approach 2:
Special connectors serve as intermediary elements between the hollow column profiles and hollow traverse profiles. These connectors simplify the connection process by providing a standardized interface that requires only insertion and clipping actions, eliminating the need for complex fastening mechanisms while ensuring stable structural connections.
2Adaptability or versatility
If fixed connection methods are used, then structural stability is improved, but adjustability and reconfigurability are reduced
Solution Approach 1:
The connection system incorporates both fixed and quick-release characteristics. The connectors can be easily inserted and removed from the hollow profiles, allowing the frame configuration to be dynamically adjusted. Once assembled, the connections provide stable fixed support for structural reliability, but can be quickly reconfigured when needed, achieving both adaptability and reliability.
Solution Approach 2:
The standardized hollow profiles and connectors serve multiple functions: they provide structural support, enable easy assembly, allow configuration adjustment, and facilitate disassembly and reconfiguration. This multi-functionality allows the same basic components to serve both as stable fixed connections and as adjustable elements, resolving the contradiction between reliability and adaptability.
3Illumination intensity
If perforated grid strips are made opaque, then structural strength is improved, but ambient lighting capability is reduced
Solution Approach 1:
The perforated grid strips are made from translucent material that allows light to pass through while maintaining sufficient structural strength. This translucent property enables the LED strips mounted on the rear to provide ambient lighting through the grid strips, while the material itself provides the necessary structural support for the frame construction.
