Full-sponge compressible sofa
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular sofa designs are complex and difficult to assemble, increasing mounting time and transportation costs.
Innovation Solution
A full-sponge compressible sofa design featuring a sponge mounting seat with symmetrically arranged armrests and sponge sofa seats, where the armrests have limiting flanges that abut against the seat cushions for precise positioning, allowing for quick assembly and disassembly, and made of cross-linked polyurethane sponge for easy compression during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular sofa with detachable mounting parts is used, then transportation and storage are facilitated, but assembly structure becomes complicated and mounting time increases
Solution Approach 1:
The patent combines the mounting parts (backrest, armrest, leg support) directly into the sofa body through integral forming, eliminating the need for separate connection elements. The mounting parts are not detachable components but are formed as one piece with the sofa body, simplifying the assembly structure while maintaining transportation convenience.
Solution Approach 2:
The sofa body is designed with multi-functional characteristics where the same structure serves both as the main body and as mounting parts. The base, backrest, armrests, and leg supports are all integrated into a single structure that performs multiple functions simultaneously, reducing the need for separate components and connection mechanisms.
2Adaptability or versatility
If modular sofa with connection elements is used, then sofa configuration can be changed, but assembly and disassembly becomes difficult and time-consuming
Solution Approach 1:
The mounting parts are merged with the sofa body through integral forming, creating a unified structure that eliminates the need for separate connection elements. This merging simplifies assembly operations while still allowing for configuration changes through the design of the integrated structure.
Solution Approach 2:
While maintaining integral forming, the sofa is segmented into functional zones (base, backrest, armrests, leg supports) that can be independently designed and positioned. This segmentation within integration allows for configuration flexibility without requiring detachable connection elements.

AI summary
A full-sponge compressible sofa includes a sponge mounting seat and at least one sponge sofa seat provided on the sponge mounting seat. The sponge mounting seat includes a base and two armrests symmetrically arranged on the base. Each armrest includes an armrest main body and a limiting flange provided on one side of the armrest main body. Each sponge sofa seat includes a seat cushion and a backrest provided on one end of the seat cushion. The side of either one of the armrests provided with the limiting flange faces the other armrest. When the sponge sofa seat is mounted on the sponge mounting seat, the limiting flange of each armrest abuts against the seat cushion of one sponge sofa seat, so as to limit the position of the sponge sofa seat on the sponge mounting seat.
