Modular Spring Bracket Assembly for Disassemblable Furniture Cushions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, is difficult to disassemble and reassemble, making them cumbersome for migration and outdoor recreation, and their integral design hinders comfort and cleanliness.
Innovation Solution
A spring module for a spring cushion comprising conical springs and a spring bracket with flexible straps, allowing for easy assembly, disassembly, and storage, with independent compressing and releasing motions for enhanced comfort, and a detachable sponge part 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 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, end cover, and mounting seat. These modules can be disassembled and reassembled freely, transforming the integrated cushion into modular components for easy storage and transport.
2Ease of operation
If independent bagged spring bed mattresses are designed with non-woven fabrics covering the bagged springs, then the springs are protected, but when the bed mattress is squeezed, a plurality of bagged springs cannot move up and down completely independently, thus affecting the comfort
Solution Approach 1:
Each spring is enclosed in its own independent module with separate end covers and mounting seats, eliminating the common non-woven fabric covering that causes interference. The modules can move independently without affecting adjacent springs.
3Ease of operation
If existing bed mattresses have an integral sponge part, then the structure is stable, but the sponge part cannot be removed, thus not easy to clean
Solution Approach 1:
The sponge is divided into multiple detachable sponge blocks that can be removed from each spring module independently. This allows the sponge parts to be taken off for cleaning while maintaining the stability of the overall structure.
4Ease of operation
If large furniture like beds needs to be disassembled frequently for migration, then mobility is improved, but the disassembly and assembly process becomes difficult and time-consuming
Solution Approach 1:
The bed is divided into modular spring modules with standardized mounting seats and end covers that can be quickly connected and disconnected. This modular design significantly reduces assembly time compared to traditional integrated furniture.
Solution Approach 2:
The spring modules can be nested within each other when disassembled, compacting the overall volume and making storage and transport much more efficient for migration purposes.
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
The spring module enables the spring cushion to be easily disassembled and stored, providing improved comfort and stability, while the detachable sponge part facilitates cleaning, addressing the challenges of mobility and hygiene in existing designs.
Implementation Method 1
one or more groups of flexible straps, each group of flexible straps comprising a plurality of flexible straps spaced apart from each other and evenly arranged between a corresponding pair of the spring mounting seat and the end cover
