Rack assembly and sub-rack thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rack assemblies lack versatility due to securely mounted and non-adjustable supporting members, limiting their use and adaptability for displaying goods.
Innovation Solution
A rack assembly design featuring slidable sub-racks with U-section rails and retractable wheels, allowing for adjustable positions and quantities of supporting members between side racks, enabling flexible placement and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If supporting members are securely mounted on the rack frame, then the rack frame has high structural stability, but the supporting members cannot be detached or adjusted, reducing versatility
Solution Approach 1:
The rack assembly is divided into a fixed rack frame and detachable sub-racks. The sub-racks can be independently removed or added, allowing the supporting members to be adjusted or detached while maintaining the stability of the main rack frame structure.
Solution Approach 2:
The supporting members are transformed from fixed to dynamic components through the introduction of sliding mechanisms and detachable connections. This allows the sub-racks to move along the rack frame and be positioned flexibly, achieving both stability and adaptability.
2Device complexity
If supporting members are fixed in position, then the structure is simple and stable, but the positions cannot be adjusted, limiting flexibility
Solution Approach 1:
A sliding mechanism with wheels acts as an intermediary between the fixed rack frame and the adjustable sub-racks. This intermediary component enables smooth movement and position adjustment while maintaining structural simplicity through standardized guides and rollers.
3Ease of manufacture
If the rack assembly has fixed configuration, then manufacturing is simple, but the rack cannot accommodate different user demands, reducing usability
Solution Approach 1:
The rack assembly is designed with universal components that can serve multiple functions. The standardized sub-racks and sliding mechanisms allow the same basic structure to accommodate various configurations and user demands, enhancing versatility without complicating manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the versatility of the rack assembly by allowing for customizable placement and quantity of sub-racks, accommodating different user demands and improving usability.
Implementation Method 1
Each one of the at least one rear rod has a rear wheel mounted rotatably on a top of the rear rod and held slidably in the rear rail
Implementation Method 2
Each one of the at least one front rod has an extension rod mounted retractably on a top of the front rod and having a top and a front wheel mounted rotatably on the top of the extension rod
