Modular Spring Mattress Assembly for Easy Disassembly and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional furniture, such as beds and couches, are difficult to disassemble and reassemble, making them cumbersome to move and store, as they consist of large, integral spring pads that cannot be easily separated or rearranged.
Innovation Solution
The design of modular elastic modules with a spring and an outer foam or sponge covering layer, which can be easily attached and detached without tools, allowing for the creation of a spring pad or mattress that can be quickly assembled or disassembled, and can be connected to form various configurations conforming to different furniture frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional integral spring pads are used, then structural strength and stability are improved, but ease of disassembly and assembly deteriorates
Solution Approach 1:
The spring pad is divided into multiple independent spring units, each containing one or more springs individually enclosed in foam rubber. These modular units can be separately assembled and disassembled while maintaining the overall structural stability when connected together to form the complete mattress.
2Strength
If traditional integral spring pads are used, then structural strength is improved, but ease of moving and storage deteriorates
Solution Approach 1:
The spring pad consists of multiple separable spring units that can be individually handled, moved, and stored. This segmentation allows the large, heavy integral structure to be broken down into manageable pieces that are easier to transport and store while maintaining structural integrity when assembled.
3Reliability
If individually bagged spring mattresses are used, then comfort and support are improved, but ease of disassembly and assembly deteriorates
Solution Approach 1:
Each spring is individually enclosed in foam rubber to provide independent comfort and support, while the entire spring unit can be easily removed from the mattress by detaching it from the connecting webbing, allowing simple disassembly without compromising the comfort benefits.
Solution Approach 2:
The spring units can be individually extracted from the mattress structure by removing them from the webbing connections, allowing easy disassembly and reassembly while maintaining the individual comfort characteristics of each spring unit.
4Ease of operation
If modular elastic modules are used, then ease of assembly and disassembly is improved, but device complexity increases
Solution Approach 1:
The spring pad is segmented into standardized modular units with consistent dimensions and connection interfaces. This segmentation simplifies assembly through repetition of the same module type while the standardization reduces the perceived complexity by creating a uniform, predictable system.
Solution Approach 2:
The spring units are designed as universal modules that can be used in various configurations and positions within the mattress. The standardized design allows the same module to serve multiple functions and be assembled in different arrangements, simplifying the overall system while maintaining ease of assembly.

AI summary
Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly Including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.
