Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assembled sofas have unstable frame structures, leading to a risk of falling apart, particularly with the back board breaking easily, necessitating an improvement in stability and assembly security.
Innovation Solution
A detachable sofa frame structure featuring vertical support bars with connecting pieces and support legs, enhancing the stability of the back board and overall frame, while allowing for easy assembly and disassembly, and incorporating a storage unit for added functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sofa is divided into multiple parts for easy transportation and assembly, then the ease of operation is improved, but the stability and reliability of the frame structure deteriorates
Solution Approach 1:
The sofa frame is divided into multiple detachable parts including side boards, face board, back board, and vertical support bars that can be separately transported and assembled. The segmentation is achieved through detachable connection structures that allow easy assembly while maintaining structural integrity when assembled.
Solution Approach 2:
The vertical support bars are pre-equipped with connecting pieces (extending upward or downward) and support legs before assembly. The connecting pieces are pre-configured to extend in specific directions to facilitate straightforward connection with the back board, and support legs are pre-attached to provide immediate ground contact and stability upon assembly, reducing the need for complex on-site adjustments.
2Ease of operation
If the sofa frame is made detachable for easy assembly, then the ease of operation is improved, but the strength and durability of the frame deteriorates
Solution Approach 1:
The frame is segmented into modular components (side boards, face board, back board, vertical support bars) that can be easily assembled and disassembled while maintaining structural strength through proper connection design.
Solution Approach 2:
The vertical support bars act as intermediary elements that strengthen the connection between the face board and back board. These support bars with connecting pieces serve as mediators that distribute and transfer loads across the detachable joints, enhancing the overall strength of the assembled frame structure.
3Device complexity
If the back board is connected directly to the side boards without additional support, then the device complexity is reduced, but the reliability of the back board connection deteriorates
Solution Approach 1:
The vertical support bars with connecting pieces serve as intermediary elements between the back board and the rest of the frame structure. These intermediaries provide additional connection points and structural support, enhancing the reliability of the back board connection without significantly increasing overall complexity.
Solution Approach 2:
The connecting pieces extend upward or downward from the vertical support bars, utilizing the vertical dimension to provide additional connection surfaces and support points for the back board. This dimensional extension allows for more robust connection without adding horizontal complexity to the frame structure.

AI summary
A sofa frame, a vertical support bar and an assembled sofa. The sofa frame includes two side boards, a face board connected between the front ends of the two side boards and a back board connected between the rear ends of the two side boards. The two side boards, the face board and the back board forms a detachable frame structure. Between the face board and the back board, a vertical support bar is connected. The rear side of the vertical support bar is fixed with a connecting piece. By fixing and connecting the connecting piece and the back board, the support of the back board is strengthened. The lower end of the vertical support bar is connected with a support leg to contact the ground. The sofa frame is a detachable structure, which can be disassembled for packaging and transportation, and assembled again later.
