Folding Sofa with Detachable Modular Frames to Reduce Packing Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding sofas with large dimensions occupy a significant surface area during packing and storage, making them inconvenient to pack and store.
Innovation Solution
The folding sofa features multiple detachable support legs and a rotatable frame structure with iron or steel tubes, elastic elements, and a flexible covering, allowing the sofa to be disassembled into smaller parts and overlapped for reduced packing space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the folding sofa has a large length and size, then it provides sufficient seating and lying space, but it occupies a large surface area in the packing box, making it inconvenient to pack and store
Solution Approach 1:
The folding sofa is divided into multiple detachable modules: seat cushion frames, backrest frames, support legs, and elastic elements. These segments can be disassembled and reconfigured, allowing the long sofa to be broken into smaller units for compact packing while maintaining sufficient length when assembled for use
Solution Approach 2:
The support legs are designed to be nested within or attached to the frame structures. When packed, the support legs can be stored within the frame assemblies, and the frame assemblies themselves can be nested or stacked together, significantly reducing the surface area occupied in the packing box while maintaining full functionality when deployed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces the overall surface area occupied by the sofa during storage, enhances strength and durability, and improves comfort through elastic elements, facilitating easy packing and storage.
Implementation Method 1
the support element includes multiple elastic elements; and two ends of each of the elastic elements are fixed inside the seat cushion frame and the backrest frame
