Solution Overview
Problem
Existing spring sofas require separate compression and reinstallation of bases, armrests, and backrests during transportation, making the process complicated and inconvenient.
Innovation Solution
A sofa design featuring an integral sofa body supported by compressible springs, allowing for complete compression and easy unpacking and assembly without reinstallation, with features like parallel springs, auxiliary material layers, and detachable feet for efficient packaging and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate compression of bases, armrests, and backrests is used, then compression is achieved, but the compression process becomes complicated and requires reinstallation
Solution Approach 1:
The patent merges the compression process by allowing the entire sofa (bases, armrests, and backrests) to be compressed as a single integrated unit. The compression mechanism applies force to the whole sofa structure simultaneously, eliminating the need for separate compression of each component and simplifying the overall operation.
Solution Approach 2:
The sofa is designed with modular components (bases, armrests, backrests) that are connected in a way that allows integrated compression while maintaining structural integrity. The segmentation enables the sofa to be compressed as one unit yet still allow for easy reassembly at the destination without complex reinstallation procedures.
2Productivity
If separate compression and reinstallation is required, then transportation is possible, but user convenience is reduced due to reinstallation requirement
Solution Approach 1:
The sofa is pre-configured with its modular components and connection mechanisms during manufacturing, so that upon arrival at the destination, users only need to perform simple unpacking and basic assembly steps. The preliminary preparation of the modular structure significantly reduces the setup effort required by end users.
3Productivity
If the sofa is designed for integral compression, then transportation efficiency is improved, but the structural design becomes more complex
Solution Approach 1:
The modular components of the sofa are designed to nest within each other during compression, with smaller parts fitting into spaces within larger components. This nesting arrangement maximizes space utilization during transportation while maintaining a relatively simple overall structure that does not require complex mechanisms.

AI summary
Disclosed in the present invention is a sofa capable of being integrally compressed, comprising an integral sofa body formed by being at least supported by compressible springs. The integral sofa body comprises bases, backrests, and armrests; the bases, the backrests, and the armrests are all formed by being supported by the compressible springs, and all the springs are parallel to one another, so that the integral sofa body can be completely compressed. The sofa capable of being completely compressed is provided, so that during transportation, the sofa can be packaged and transported after being completely compressed, facilitating the transportation of the sofa; the sofa can be integrally compressed, so that when the compressed sofa is transported to a place where the sofa needs to be used, the sofa can be reset and formed by simply unpacking same, does not need to be re-installed, and is easy to use quickly.
