Modular sofa
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sofas have fixed component configurations, limiting the ability to assemble them in different ways to create varied sofa designs.
Innovation Solution
A modular sofa design featuring detachable base and backrest assemblies, connected via connection members, allowing for flexible assembly into one-seater, two-seater, or three-seater configurations, with adjustable seat cushions and stable connections using receiving holes and connecting members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sofa components (bases, backrest assemblies, armrest assemblies) are fixed to one another, then structural stability is improved, but configurability and adaptability deteriorate
Solution Approach 1:
The sofa is divided into separate modular components (bases, backrest assemblies, armrest assemblies) that can be independently manufactured and then connected through connection members, allowing both structural stability when assembled and configurability when disassembled or rearranged
Solution Approach 2:
The connection members enable dynamic reconfiguration of the sofa components, allowing users to assemble and disassemble parts to create different configurations (e.g., changing from a two-seater to a one-seater arrangement) while maintaining stable connections during each configuration
2Adaptability or versatility
If sofa components are designed for detachable connection, then adaptability and customization are improved, but device complexity increases
Solution Approach 1:
The connection members are designed with universal functionality to work with multiple component types (bases, backrest assemblies, armrest assemblies), allowing the same connection mechanism to be used throughout the sofa system, which simplifies the overall design despite the modular complexity
Solution Approach 2:
The connection members are strategically positioned at specific locations (e.g., at the corners or edges of components) to enable detachable connection, concentrating the complexity only where needed for assembly rather than distributing it throughout the entire structure

AI summary
A sofa includes: a base assembly comprising a base that comprises at least one of a first connection member and a second connection member; wherein the first connection member is configured to detachably connect with a base connecting member, two bases are detachably connectable to each other through the first connection member and the base connecting member; the second connection member is configured to detachably connect with a backrest connecting member, thereby allowing a backrest connected to the backrest connecting member to be detachably connected to the base assembly.
