Modular Spring Cushion Design for Easy Disassembly and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, is difficult to disassemble and reassemble, and existing spring mattresses are not easily disassembled or cleaned, leading to storage and transportation challenges and health risks due to non-woven fabrics adhering to each other, which affects comfort and hygiene.
Innovation Solution
A spring module comprising conical springs and a spring bracket with flexible straps and connectors that allow for easy assembly, disassembly, and stacking, along with a detachable sponge pad for enhanced cleaning and comfort, enabling independent motion of springs and adjustable stiffness.
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, base, and end cover. These modules can be separately disassembled and stored, transforming the integrated structure into modular components that are easier to handle and store while maintaining structural stability when assembled.
Solution Approach 2:
The spring modules are designed to be stackable and nestable, with the end cover of one module fitting over the base of another. This nesting capability allows multiple modules to be compactly stored together, significantly reducing storage space requirements while maintaining the integrity of each individual module.
2Stability of the object's composition
If independent bagged spring bed mattresses use non-woven fabrics adhered together, then the structure is stable, but the bagged springs cannot move up and down completely independently, affecting comfort
Solution Approach 1:
Each spring is housed in its own independent module with separate base and end cover, eliminating the need for non-woven fabrics to hold springs together. This segmentation allows each spring to move independently without interference from adjacent springs, improving comfort while maintaining structural stability through the modular design.
Solution Approach 2:
The non-woven fabric layer is completely removed from the design. Instead of using fabric to bind springs together, the invention uses individual modular housings for each spring, extracting the binding function and replacing it with physical separation through modular compartments.
3Device complexity
If existing bed mattresses use integrated sponge parts, then the structure is simple, but the sponge part cannot be removed and is difficult to clean
Solution Approach 1:
The sponge is divided into multiple detachable sponge blocks that can be separately removed from each spring module. This segmentation allows the sponge components to be easily taken out for cleaning or replacement while maintaining a relatively simple overall structure, resolving the contradiction between structural simplicity and cleaning ease.
4Ease of operation
If spring modules are designed for easy disassembly, then they are easy to assemble and store, but the structure becomes more complex
Solution Approach 1:
The base and end cover are designed as integrated components that form the housing for each spring module. This merging of structural elements simplifies the overall design by reducing the number of separate parts, making assembly and storage easier while avoiding excessive structural complexity.
Solution Approach 2:
The base and end cover serve multiple functions: they house the spring, provide structural support, enable stacking through complementary geometries, and facilitate disassembly and reassembly. This multi-functionality reduces the need for additional specialized components, maintaining structural simplicity while achieving ease of operation.
