Modular Cabinet Assembly with Pivoting Boards for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cabinets are cumbersome for storage, transportation, and packaging due to their large size and complex assembly requirements, which involve significant space occupation and time-consuming assembly processes prone to errors.
Innovation Solution
A modular cabinet assembly comprising sub-cabinets with pivotably connected back and side boards, removably attached shelf boards, and a connector system that allows for efficient folding and assembly, reducing space occupation and simplifying the assembly process through the use of clamps and hinges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cabinet is disassembled and stacked in the prior art manner, then the cabinet can be stored and transported, but the occupied area is large and it is not convenient for carrying
Solution Approach 1:
The cabinet is divided into multiple sub-cabinets that can be independently folded and stacked. Each sub-cabinet contains a back board with left and right side boards that can be folded against each other, creating compact units that are easier to carry and store compared to a single large disassembled cabinet.
Solution Approach 2:
The disassembled cabinet components are designed to nest within each other during folding. The side boards fold against the back board, and sub-cabinets can be stacked vertically, creating a compact nested configuration that reduces the overall occupied area and improves portability.
2Ease of manufacture
If the cabinet components are assembled and fixed one by one in the prior art manner, then the cabinet can be assembled, but the assembly process is complicated, time-consuming and subject to error
Solution Approach 1:
The cabinet components are pre-configured with pivot connections and folding mechanisms during manufacturing. The back boards are pre-attached to side boards with pivot shafts, and shelves are pre-positioned with removable connections, allowing users to simply unfold and stack the pre-assembled sub-cabinets rather than assembling individual components from scratch.
Solution Approach 2:
The cabinet uses dynamic folding mechanisms with pivot connections that allow components to move from a folded storage position to an unfolded assembled position. This dynamic design enables quick transformation between compact and expanded states, significantly reducing assembly time and complexity compared to static fixed-component assembly.
3Volume of moving object
If the cabinet is made in component parts for cost-effective storage and shipping, then storage and shipping costs are reduced, but the assembly becomes complicated and time-consuming
Solution Approach 1:
The cabinet is segmented into modular sub-cabinets that can be independently folded and stacked for compact storage and shipping. Each sub-cabinet is a self-contained unit with integrated back and side boards, reducing the overall volume when disassembled while maintaining simple assembly through standardized folding mechanisms.
Solution Approach 2:
The back board and side boards are merged into integrated sub-cabinet units with pivot connections, combining multiple components into cohesive modules. This merging reduces assembly complexity by eliminating the need to separately assemble individual boards while still enabling compact folding for cost-effective storage and shipping.

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.
