Storage Rack Trays With Locating Blocks For Variable Box Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage racks with pivot shafts and trays can only accommodate flat accessories boxes of a single size, limiting the ability to arrange different combinations of box sizes.
Innovation Solution
The storage rack features trays and accessories boxes made of plastic, with recessed locating holes on the boxes and springy locating blocks on the trays that securely engage and allow for the detachment of boxes of varying sizes, enabling flexible arrangement and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one single size of flat accessories boxes is used, then the structure is simple, but the adaptability is poor
Solution Approach 1:
The tray is divided into multiple compartments with different sizes, allowing different sized boxes to be arranged flexibly. The tray body includes first, second, and third compartments of varying dimensions, enabling users to place different sizes of flat accessories boxes in different compartments according to their needs.
Solution Approach 2:
The tray is designed to accommodate multiple sizes of flat accessories boxes simultaneously through its multi-compartment structure. Each compartment can hold boxes of different dimensions, making the tray universally adaptable to various box sizes rather than being limited to a single size.
2Ease of operation
If flat accessories boxes are made detachable, then the ease of operation is improved, but the reliability of positioning is worsened
Solution Approach 1:
The tray compartments are pre-designed with specific dimensional specifications that match the sizes of flat accessories boxes. The locating holes are positioned in advance at optimal locations to ensure proper alignment and secure positioning when boxes are placed in the compartments, enabling both easy detachment and reliable positioning.
Solution Approach 2:
Locating holes are introduced as intermediary elements between the tray compartments and the flat accessories boxes. These locating holes receive corresponding locating protrusions on the boxes, providing precise positioning and secure engagement while still allowing easy insertion and removal of the boxes.
