Assembly Sofa with Nested Armrest Storage to Reduce Packing Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly sofas face challenges in reducing logistics transportation costs while maintaining structural firmness and avoiding increased production costs due to excessive disassembly.
Innovation Solution
The assembly sofa design includes a sofa seat frame with backrest and seat plates, armrest boxes with cavities for storing disassembled components, and a compact structure that allows for efficient packing and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the sofa is disassembled into many components to narrow packing spaces, then container storage capacity is improved, but structural firmness becomes insufficient and product quality deteriorates
Solution Approach 1:
The sofa is divided into modular components including seat frames, backrests, armrests, and cushions that can be disassembled and reassembled. This segmentation allows compact packing while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
Components are designed to nest within each other during packing - armrests fit into seat frames, backrests fit into armrests, and cushions are placed within the nested structure. This nesting approach maximizes space utilization while preserving structural relationships.
2Loss of energy
If the sofa is disassembled into many components to reduce logistics costs, then storage capacity is improved, but production and manufacturing costs increase
Solution Approach 1:
Standardized connection components and modular design elements are used across different sofa configurations, allowing the same production processes and parts to serve multiple product variants. This universality reduces manufacturing complexity and cost despite the modular disassembled structure.
3Volume of moving object
If cushions are compressed to vacuum state for storage, then packing space is reduced, but cushion comfort and structure are affected
Solution Approach 1:
Cushions are pre-compressed to a vacuum state before packaging, allowing them to occupy minimal space during transportation. The compression is applied in advance, and cushions are designed with structural elements that maintain their integrity even when compressed, ensuring they can be easily re-expanded to full comfort upon assembly.

AI summary
Disclosed is an assembly sofa. The assembly sofa includes a sofa seat frame; a plurality of backrest plates, transversely laid side by side and connected to a rear side of the sofa seat frame; a plurality of seat plates, transversely laid side by side and connected to a top of the sofa seat frame; a plurality of cushions, arranged on the backrest plates or/and the seat plates; and two armrest boxes, connected to two sides of the sofa seat frame respectively, wherein the armrest boxes are provided with cavities inside and openings in bottom ends, the cavity of one armrest box is used for storing the stacked backrest plates when the assembly sofa is packed, and the cavity of the other armrest box is used for storing the vacuum-compressed cushions when the assembly sofa is packed. The present disclosure has the beneficial effects of narrowing packing spaces.
