Innovation Solution
A modular cabinet assembly comprising sub-cabinets with pivotably connected back and side boards, removable shelf boards, and a connector system that allows for efficient folding and quick assembly/disassembly, reducing space occupation and simplifying the assembly process through the use of clamps and hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cabinet is manufactured in component parts and disassembled for storage, then the cabinet can be stored and shipped cost-effectively, but the disassembled cabinet occupies large space and is inconvenient for carrying
Solution Approach 1:
The cabinet is divided into multiple sub-cabinets, each with foldable back boards and side boards. The back board is divided into at least two separate pieces that can be folded relative to each other, and side boards are separable from the back board. This segmentation allows each component to be compactly folded and stacked, significantly reducing the occupied storage area while maintaining ease of manufacture and assembly.
Solution Approach 2:
The disassembled cabinet components are designed to nest within each other. The side boards can be positioned inside the cabinet body, and the foldable back board pieces can be nested against each other in a compact configuration. This nesting arrangement minimizes the overall occupied space during storage and transportation, addressing the contradiction between ease of manufacture and storage area.
2Reliability
If the cabinet components are assembled and fixed one by one, then the cabinet can be properly constructed, but the assembly process is complicated, time-consuming and subject to error
Solution Approach 1:
The cabinet components are pre-configured with connection features and folding mechanisms during manufacturing. The back board pieces are pre-connected with pivotable joints, side boards are pre-equipped with connection means, and shelf boards have removable connection features. This preliminary preparation allows users to simply unfold and connect components in a straightforward sequence during assembly, dramatically reducing assembly time and minimizing errors while ensuring proper construction.
Solution Approach 2:
The cabinet employs dynamic connection mechanisms including pivotable joints between back board pieces, pivotable connections between side boards and back boards, and removable connections for shelf boards. These dynamic features allow components to be easily moved, connected, and secured during assembly without complex fastening procedures. The connections can be quickly made and adjusted, reducing assembly time while maintaining construction reliability.
3Quantity of substance
If the cabinet is designed as a large cube shape with height much larger than widths, then the cabinet provides adequate storage capacity, but the components have very large size differences making packaging and transportation inconvenient
Solution Approach 1:
The large cube-shaped cabinet is segmented into multiple smaller sub-cabinets with more uniform dimensions. Each sub-cabinet maintains adequate storage capacity while having proportions that are more suitable for packaging and transportation. The back board is further segmented into multiple foldable pieces, and side boards are made separable, allowing the components to be collapsed into compact, uniform sizes that are convenient for packaging without sacrificing overall storage capacity when assembled.
Solution Approach 2:
The cabinet design incorporates foldable back boards and separable side boards that can be collapsed in the vertical dimension during disassembly. This dimensional transformation allows the components to transition from a large three-dimensional cube shape to a compact, flattened configuration suitable for packaging and transportation, while maintaining the storage capacity when reassembled.

Function Achieved in This Case
The modular design significantly reduces the occupied space during disassembly, facilitates easy transportation and storage, and simplifies the assembly process by allowing quick unfolding and fixing of components, minimizing the risk of assembly errors and improving usability.
Implementation Method 1
a back board having at least two separate back board pieces that are pivotably connected to each other, a left side board pivotably connected to one of the at least two back board pieces, and a right side board pivotably connected to another of the at least two back board pieces
Implementation Method 2
the back board can be folded in half during disassembly, so as to further reduce the space occupied by the disassembled cabinet

AI summary
A modular cabinet assembly has at least a first sub-cabinet and a second sub-cabinet. Each sub-cabinet includes a back board having at least two separate back board pieces that are pivotably connected to each other, a left side board pivotably connected to one of the at least two back board pieces, and a right side board pivotably connected to another of the at least two back board pieces. At least one shelf board having opposite ends is removably connected to the left side board and the right side board of either the first sub-cabinet or the second sub-cabinet. A first end board is connected to either an upper end of the first sub-cabinet or a lower end of the second sub-cabinet. A first connector removably connects the left side boards of the first and second sub-cabinets, and a second connector removably connects the right side boards of the first and second sub-cabinets.
