Modular sofa
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sofas are inconvenient for assembly, transportation, and storage due to their heavy weight and large volume, leading to high transportation costs and instability during use.
Innovation Solution
A modular sofa design featuring detachable components, including a sofa seat plate, back plate, side plates, and legs, connected by trapezoidal protrusions and slots for easy assembly and disassembly, along with elastic cushions and a compact storage module for reduced transportation volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sofas are designed with integrated structure, then stability and ease of use are improved, but transportation cost and difficulty increase
Solution Approach 1:
The sofa is divided into multiple independent modules including seat modules, backrest modules, and armrest modules that can be detached from each other. Each module contains complete functional elements, allowing the sofa to be disassembled into manageable sections for easy transportation while maintaining structural integrity and stability when assembled.
2Ease of manufacture
If traditional sofas are disassembled for transportation, then transportation cost and ease are improved, but assembly complexity and cost increase
Solution Approach 1:
Multiple functional components are merged into integrated modules. For example, the seat module combines the seat plate, seat cushion, and connecting structures into a single unit. This merging reduces the number of separate parts that need to be assembled while maintaining the ability to detach for transportation.
Solution Approach 2:
The sofa modules are designed with self-aligning connection structures featuring guide rails and positioning protrusions that automatically guide the assembly process. Users can easily connect modules together without requiring professional tools or expertise, as the design itself facilitates the assembly operation.
3Ease of manufacture
If traditional sofas are disassembled for transportation, then transportation cost is improved, but stability and ease of use deteriorate
Solution Approach 1:
The connection structures between modules are pre-designed with built-in locking mechanisms and reinforcing elements. The connection plates and fastening structures are prepared in advance to ensure that when modules are assembled, they form a stable and rigid structure capable of withstanding normal use forces.
