Modular Filing Tray Assembly for Expandable Tiered Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filing systems have limited expandability and space, requiring additional support for stacking and often occupying fixed space during usage and storage, lacking the ability to alter size or number of trays.
Innovation Solution
A multi-tiered expandable filing assembly with modular trays supported by lateral frames featuring convex and concave humps for secure stacking and lateral expansion, allowing for vertical and lateral expansion through additional tray arrangements, and disassembly for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple file trays are constructed within a fixed structure divided into rows and columns, then the filing system provides organized storage, but the user cannot alter the size of the entire structure or the number of trays for usage
Solution Approach 1:
The filing system is divided into separate modular trays that can be independently added, removed, or reconfigured. Each tray is a discrete unit that can be stacked or arranged in different configurations, allowing the overall system size and capacity to be adjusted based on user needs without requiring a complete restructuring of the entire filing system.
Solution Approach 2:
The filing system transitions from a static fixed structure to a dynamic reconfigurable system. The modular trays can be easily assembled and disassembled, allowing users to adapt the number and arrangement of trays to changing storage requirements. The system evolves from a permanent installation to a flexible arrangement that can be modified without tools or complex procedures.
2Volume of moving object
If a simple file tray with a permanent structure is used, then the tray can receive and organize files, but it must occupy the same space during usage and transportation
Solution Approach 1:
The modular trays are designed to nest within each other when not in use, similar to nested dolls. Multiple trays can be stacked vertically or arranged in compact configurations that minimize the overall volume occupied during storage or transportation. This nesting capability allows the filing system to transition from an expanded operational state to a compact storage state, significantly reducing the space required when the trays are not actively being used.
3Strength
If wire trays and shelves are constructed to be load-bearing, then they can support files and documents, but the mesh is usually welded to the supports making them difficult to reconfigure
Solution Approach 1:
The load-bearing function is segmented from the support structure. Instead of welding trays to a permanent support framework, the modular trays themselves provide the necessary structural strength to bear loads independently. Each tray is designed as a self-supporting unit with integrated reinforcement, eliminating the need for welded connections to external supports while maintaining load-bearing capacity.
Solution Approach 2:
The system transitions from a static welded construction to a dynamic snap-fit assembly. The trays maintain their load-bearing strength through optimized structural design while allowing for easy reconfiguration through reversible connection mechanisms. Users can add, remove, or rearrange trays based on changing storage needs without compromising the structural integrity or load-bearing capacity of the system.

AI summary
A multi-tiered expandable filing assembly provides at least three modular trays arranged in stacked tiers and supported from two side by a pair of lateral frames. The modular trays receive, store, sort, and organize files, documents, and mail. The modular trays comprise a panel, a peripheral region, and at least one protrusion extending from the periphery. The protrusion extends from the sides of the panel and are configured to couple with the concave humps that form in the support bars of the lateral frames. The modular trays are arranged into three tiers and expanded to additional tiers of trays through constructive arrangement with the lateral frames. The lateral frames comprise a pair of legs, a top bar forming a top convex hump, and a bottom bar forming a bottom convex hump. The top and bottom convex humps from multiple assemblies can be stacked to further expand the assembly.
