Modular Spring Cushion Assembly for Easy Disassembly and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, are difficult to disassemble, transport, and clean, and traditional independent bagged spring mattresses lack independent spring movement and comfort due to adhered non-woven fabrics, leading to space inefficiency and health risks.
Innovation Solution
A spring module with a flexible connecting part outside the spring, allowing independent motion and easy assembly/disassembly, featuring a base for stability and adjustable stiffness, with a detachable sponge part for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing spring cushions are made as integrated non-disassemble cushions, then the structure is simple and stable, but they are large in size and not easy to disassemble and store
Solution Approach 1:
The spring cushion is divided into multiple independent spring modules, each containing a spring unit with hooks. These modules can be easily assembled and disassembled while maintaining structural stability when connected, resolving the contradiction between integrated stability and ease of disassembly
2Reliability
If independent bagged spring bed mattresses are made as integral products, then the springs are protected from interference, but the product is non-disassemble and not easy to transport
Solution Approach 1:
The mattress is segmented into multiple spring modules that can function independently while being transportable as separate units. Each module maintains spring independence through its own protective structure, yet the entire system can be easily transported by disassembling into smaller modules
3Reliability
If non-woven fabrics are used to cover bagged springs, then the springs are protected, but the fabrics are adhered to each other causing springs to cannot move up and down completely independently
Solution Approach 1:
The non-woven fabric covering is removed entirely from the spring structure. Instead, a flexible strap with hooks provides protection and connection functionality, allowing springs to move independently without fabric adhesion while maintaining necessary protection
4Device complexity
If the sponge part is integrated into the bed mattress, then the structure is simple, but it cannot be removed making cleaning difficult
Solution Approach 1:
The mattress is segmented into separate spring modules and a removable sponge cover. The sponge cover can be detached for cleaning while the spring modules remain in place, maintaining structural simplicity while enabling easy maintenance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables compact storage and transportation, improved comfort through independent spring motion, and easy cleaning of the sponge part, enhancing usability and convenience.

AI summary
The present disclosure provides a spring module for making a spring cushion of furniture, the spring module comprising a conical spring (110; 110a; 110b); and a one-piece flexible sleeve (1231g; 1231h) shaped to conform to a shape of the conical spring and having a closed end and an open end, the conical spring being configured to enter into an interior of the one-piece flexible sleeve through the open end; and one or more fasteners (129g); wherein an end of the open end of the one-piece flexible sleeve is bent toward an interior of the conical spring around a large diameter end of the conical spring, and fixed on an adjacent portion of the one-piece flexible sleeve positioned outside the conical spring by the one or more fasteners.
