Spring module and spring cushion for furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, are difficult to disassemble, transport, and clean due to their integral design, which affects mobility and hygiene.
Innovation Solution
A spring module with a flexible connecting part and a detachable sponge part, allowing for easy assembly and disassembly, compact storage, and independent spring motion, along with a modular design that includes compartments and zippers for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing spring cushions are designed as integrated non-disassemble cushions, then the structure is simple and stable, but the furniture is difficult to disassemble, transport, and store
Solution Approach 1:
The spring cushion is divided into multiple independent spring modules, each containing a spring, base cloth, and sponge block. These modular units can be easily disassembled, transported, and reassembled, directly resolving the contradiction between operational ease and structural complexity.
2Reliability
If independent bagged spring bed mattresses are used, then mutual interference between users is avoided, but the non-woven fabrics adhere springs together preventing independent motion and reducing comfort
Solution Approach 1:
The springs are extracted from the adhesive non-woven fabric bags and placed into individual spring modules with separate base cloths. This extraction eliminates the adhesive constraint that prevented independent spring motion, allowing each spring to move freely while maintaining user isolation benefits.
3Ease of operation
If the sponge part is integrated into the bed mattress, then the structure is simple, but the sponge cannot be removed making cleaning difficult
Solution Approach 1:
The sponge block is segmented from the main mattress structure and integrated as a removable component within each spring module. This segmentation allows the sponge to be easily removed for cleaning while maintaining a relatively simple overall structure through modular design.
4Reliability
If springs are individually packaged in bags or sleeves, then mutual interference is avoided, but the product becomes integral and non-disassemble making transport difficult
Solution Approach 1:
The spring cushion system is segmented into discrete spring modules that can be independently handled and transported. Each module maintains spring isolation through its own base cloth and structure, preventing interference while enabling easy transport and storage.
Solution Approach 2:
The spring modules can be nested or stacked within each other when not in use, significantly reducing transport and storage space while maintaining the individual spring isolation that prevents interference.
