Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional iron frame sofas with foldable hinge structures face issues such as high transportation and packaging costs due to inefficient disassembly and assembly methods, environmental impact from non-renewable materials, and excessive use of harmful glues and packaging materials.
Innovation Solution
An iron frame sofa design featuring a foldable hinge structure with connecting square tubes, supporting legs, a grille supporting frame, and foldable assembling pipes that utilize foldable hinges to minimize volume, allowing for easy disassembly and reassembly, reducing material usage and transportation costs, and promoting environmentally friendly production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional disassembly and assembly methods using screws are used, then the sofa can be assembled and disassembled, but the process is inconvenient and time-consuming
Solution Approach 1:
The sofa is divided into modular components (seat frame, backrest, armrests, legs) that can be independently assembled and disassembled. Each component is designed with specific connection interfaces that enable quick attachment and detachment without requiring complex tools or procedures.
Solution Approach 2:
The connection mechanisms between sofa components are designed to be dynamically adjustable, allowing for quick insertion and removal. The joint structures enable smooth transitions between assembled and disassembled states, reducing the time and effort required for assembly operations.
2Volume of moving object
If the sofa is designed with a fixed structure, then it maintains structural stability, but it occupies excessive space during transportation and increases packaging costs
Solution Approach 1:
The sofa structure is segmented into multiple detachable components that can be folded and nested together. The seat frame, backrest, and armrests are designed as separate modules that can be collapsed into a compact configuration, significantly reducing the volume required for transportation and storage while maintaining structural integrity when assembled.
Solution Approach 2:
The sofa components are designed to nest within each other when disassembled. Larger components such as the seat frame provide structural support and can accommodate smaller components like armrests and legs, creating a compact nested configuration that minimizes packaging volume while preserving the stability of the original structure when reassembled.
3Object-affected harmful factors
If traditional packaging materials are used for the foldable sofa, then the product is protected during transportation, but packaging costs increase and environmental pollution worsens
Solution Approach 1:
The sofa structure itself serves as its own packaging protection. The folded and nested configuration of the modular components provides inherent structural protection during transportation, eliminating or reducing the need for additional protective packaging materials. The design leverages the sofa's own geometry and material properties to protect against damage during shipping.
Solution Approach 2:
The design eliminates the need for single-use protective packaging materials by using the sofa's own structure for protection. This approach discards traditional packaging materials entirely, reducing waste and environmental pollution while lowering packaging costs. The sofa components are designed to be recovered and reused in their original form without requiring disposable protective coverings.

AI summary
The present application relates to the technology field of iron frame sofa, in particular to an iron frame sofa with a foldable hinge structure. The iron frame sofa includes a sofa mainframe with connecting square tubes mounted at four inner corners of the sofa mainframe. Supporting legs are mounted at bottom of the connecting square tubes. A grille supporting frame is mounted on top of the sofa mainframe. A first assembling pipe seat is mounted on both sides of a back of an inner wall of the sofa mainframe. A first assembling pipe is sleeved with the first assembling pipe seat at top end of the first assembling pipe seat. A second assembling pipe seat is mounted on both of a front and a rear side of a right side of the inner wall of the sofa mainframe. A second assembling pipe is sleeved with the second assembling pipe seat at top end of the second assembling pipe seat. Folding hinges are mounted at both ends of the top of the second and first assembling pipes. The overall structure of the iron frame sofa is simple, and it is convenient to minimize packaging volume by folding the armrest and backrest frame by hinges, which can save space and reduce transportation costs and save packaging materials and have high stability and practicality, having certain promotion value
