Foldable drawer and the drawer chest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawers for writing desks, computer desks, and drawer chests are cumbersome to transport and assemble, requiring separate packaging and tedious field assembly, especially for drawer chests which complicate the process of combining drawers with main bodies using sliding rails.
Innovation Solution
A foldable drawer design with articulated or bendable structures allowing the drawer components to fold and retract during transportation, simplifying assembly by enabling components to be opened perpendicular to the side plates at the installation site, eliminating the need for complex assembly processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If drawers are transported separated from the main body to reduce packaging volume, then transportation is facilitated, but field assembly becomes tedious and troublesome
Solution Approach 1:
The drawer is divided into multiple separable components including drawer side plates, drawer bottom plates, drawer front panels, and drawer back baffles that can be transported independently and assembled at the installation site through turning structures
Solution Approach 2:
The drawer components are designed with turning structures that enable dynamic transformation between folded transport state and assembled operational state, allowing the drawer to transition from a compact configuration during transport to a functional configuration during assembly
2Volume of moving object
If drawers are split and packaged separately to reduce packaging volume, then transportation is facilitated, but the assembly process requires complex sliding rail combinations
Solution Approach 1:
The turning structure integrates multiple functions into a single component that simultaneously serves as a connection element, a positioning element, and an assembly guide, eliminating the need for separate sliding rail components and simplifying the overall assembly process
Solution Approach 2:
The complex sliding rail mechanism is extracted and replaced with a simplified turning structure that achieves the same functional outcome of connecting drawer components to the main body without requiring complex intermediate elements

AI summary
The present relates to a foldable drawer, it's provided with a drawer bottom plate, a left drawer side plate, a right drawer side plate, a drawer back baffle, and a drawer front panel. A foldable opening and closing structure of the foldable drawer is as follows: the drawer bottom plate is designed as left and right parts. A turning structure that enables the left and right parts of the drawer bottom plate to turn relative to each other is arranged between the left and right parts of the drawer bottom plate. Each part of the drawer bottom plate consists of at least one piece. Before delivery, the drawer is folded and retracted, which facilitates transportation. During site installation, a drawer main body is formed by only pulling the drawer side plates open, so that the assembly efficiency of the drawer is improved.
