Combination furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional furniture is bulky and inconvenient for transportation, and when damaged, it requires skilled professionals for repair, leading to high maintenance costs due to its integral design and lack of replaceable parts.
Innovation Solution
The combination furniture design features independently manufactured main cushions, armrests, and backrests that are assembled on a base with strip-shaped coupling grooves and fasteners, allowing for easier assembly, transportation, and user-replaceable components, reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional furniture is integrally made in one piece, then structural strength is improved, but transportation convenience deteriorates due to large volume
Solution Approach 1:
The furniture is divided into multiple independent modules including seat cushions, backrests, armrests, and base components. Each module can be separately manufactured, transported, and assembled, significantly reducing transportation volume while maintaining structural integrity through standardized coupling mechanisms between modules
2Stability of the object's composition
If traditional furniture is integrally made in one piece, then structural stability is improved, but ease of repair deteriorates as damaged parts cannot be simply replaced
Solution Approach 1:
The furniture structure is segmented into replaceable modules with standardized coupling interfaces. When a component is damaged, only that specific module needs to be detached and replaced, while the rest of the furniture remains intact. This modular design dramatically improves repairability while maintaining overall structural stability through the coupling mechanisms
Solution Approach 2:
The design enables individual components to be discarded and replaced independently rather than requiring repair of the entire furniture piece. Users can replace damaged cushions, backrests, or armrests by simply detaching them from the base, recovering the functional value of the furniture without professional repair intervention
3Volume of moving object
If combination furniture uses metal skeletons and attachments, then transportation convenience is improved, but manufacturing complexity increases due to large skeleton volume
Solution Approach 1:
Instead of using a single large metal skeleton, the furniture employs multiple small modular components that can be independently manufactured and assembled. This segmentation reduces the volume of individual parts for transportation while simplifying manufacturing through standardized production of identical modules
Solution Approach 2:
The base structure incorporates universal coupling mechanisms that can accommodate various types of cushions, backrests, and armrests. This multi-functional design simplifies manufacturing by using standardized interfaces across different components, reducing overall manufacturing complexity despite the modular nature of the furniture
4Ease of manufacture
If combination furniture uses metal skeletons and attachments, then ease of assembly is improved, but maintenance cost remains high due to professional repair requirements
Solution Approach 1:
The furniture is designed with segmented modular components that can be easily assembled by users through simple coupling mechanisms. The same modularity that facilitates easy assembly also enables easy replacement of damaged parts, allowing users to maintain the furniture themselves without requiring professional repair services, thereby reducing maintenance costs

AI summary
A combination furniture includes a base, a main cushion, two armrests, a backrest, and a fastener assembly. The top surface of the base is concavely provided with plural strip-shaped coupling grooves. The main cushion has a bottom plate provided with plural coupling strips integrally projecting from the bottom plate for being coupled with the coupling grooves. The two armrests have a pair of combining parts formed in parallel and slidingly and transversely installed on two sides of the base, respectively. The backrest has a pair of fixing parts formed on the backrest in parallel for correspondingly overlapping the two combining parts of the two armrests. The fastener assembly fastens the combining parts and the corresponding fixing parts to the base. Therefore, the combination furniture is easily assembled, manufactured, and transported.
