Modular Storage Cabinet Assembly Using Engagement Portions and Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal safe deposit cabinets face issues with non-detachable integral welded structures having high transportation costs and boltable combined structures with high site mounting costs and low mounting efficiency due to the need for multiple connecting bolts.
Innovation Solution
A storage cabinet design featuring a door frame, rotatable cabinet door, left and right plates connected via engagement portions and hinges, and top and bottom plates connected with fasteners, reducing the number of fasteners needed for assembly and allowing for easier disassembly and packaging, enhancing assembly efficiency and structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If integral welded structures are used for cabinet bodies, then structural stability is improved, but transportation costs increase and disassembly becomes difficult
Solution Approach 1:
The cabinet body is divided into multiple detachable plates (front plate, rear plate, left plate, right plate, top plate, bottom plate) that can be separated for transportation and reassembled at the installation site. Each plate is connected through engagement portions and hinges rather than permanent welding, enabling modular segmentation that reduces transportation costs while maintaining structural integrity when assembled.
2Ease of operation
If boltable combined structures are used for cabinet bodies, then disassembly becomes easier, but the number of connecting bolts increases and mounting efficiency decreases
Solution Approach 1:
The patent extracts and eliminates the need for multiple connecting bolts by designing engagement portions with built-in positioning and fixing功能的凸出部 and 凹陷部 structures. The hinges and engagement portions integrate multiple functions (connection, positioning, limiting movement) into single components, reducing the total number of fastening elements required while maintaining ease of assembly and disassembly.
Solution Approach 2:
The engagement portions and hinges serve multiple functions simultaneously: they connect adjacent plates, provide positioning through shaped structures, limit relative movement, and enable both assembly and disassembly operations. This multi-functionality reduces the number of separate components needed while simplifying the overall assembly process.
3Strength
If multiple connecting bolts are used for plate connections, then connection strength is improved, but mounting time increases and mounting efficiency decreases
Solution Approach 1:
The engagement portions are pre-formed with positioning structures (protrusions and recesses) that automatically align adjacent plates during assembly. The hinges are pre-assembled with plates, so when plates are brought together, the connection features are already in place, eliminating the need for multiple separate bolting operations and significantly reducing mounting time while maintaining connection strength.
