Modular cabinet assembly
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 multiple components and time-consuming assembly processes.
Innovation Solution
A modular cabinet assembly comprising sub-cabinets with pivotably connected back and side boards, allowing for efficient disassembly and assembly by folding the components, thereby reducing the occupied space and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cabinet is manufactured in component parts and disassembled for storage, then the cabinet can be stored and shipped more efficiently, but the occupied area after disassembly remains large and inconvenient for carrying
Solution Approach 1:
The cabinet is divided into multiple sub-cabinets, each with its own back board and side boards that can be independently folded and stored. This segmentation allows each component to be compacted separately, reducing the overall storage volume while maintaining ease of handling for individual units.
Solution Approach 2:
The back boards and side boards are designed with pivot connections that allow them to transition between extended (assembled) and folded (disassembled) positions. This dynamic design enables the cabinet components to change their configuration, reducing the occupied area when disassembled while maintaining structural integrity when assembled.
2Ease of manufacture
If the cabinet components are disassembled and stacked, then the cabinet can be packed and shipped cost-effectively, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The back boards and side boards are pre-connected through pivot joints during manufacturing, creating a pre-assembled sub-cabinet unit. This preliminary connection eliminates the need for complex on-site assembly, as users only need to unfold and secure the pre-connected components rather than assembling multiple separate parts.
Solution Approach 2:
Multiple cabinet components (back boards and side boards) are merged into integrated sub-cabinet units with permanent pivot connections. This merging reduces the number of separate assembly steps required, transforming a complex multi-component assembly process into a simpler unfolding and securing operation.
3Volume of moving object
If the cabinet is designed as a large cube shape, then it provides adequate storage space, but the components have very large size differences making packaging and storage inconvenient
Solution Approach 1:
The large cube-shaped cabinet is segmented into multiple smaller sub-cabinets, each with proportionally sized components. This segmentation reduces the size difference between individual components, making them more uniform and easier to package and store while collectively maintaining the total storage capacity of the original large 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.
