Modular Spring Bracket Assembly for Easy Disassembly and Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, is difficult to disassemble and reassemble, making it cumbersome for migration and outdoor recreation, and the integral spring cushions are not easily disassembled or cleaned, affecting comfort and hygiene.
Innovation Solution
A spring module design featuring a conical spring and a spring bracket with flexible straps and locking structures allows for easy assembly and disassembly, independent motion of springs, and a detachable sponge pad for cleaning, enabling compact storage and improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spring cushions are made as integral non-disassemble structures, then structural stability is improved, but ease of disassembly and storage is worsened
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 easily assembled and disassembled while maintaining structural stability when connected through locking structures. The segmentation allows the cushion to be taken apart for storage or cleaning without compromising the integrity of individual components.
2Ease of manufacture
If spring cushions are made as integral structures, then manufacturing simplicity is improved, but ease of cleaning is worsened
Solution Approach 1:
The spring cushion consists of multiple independent modules with detachable components including removable end covers and separable bases. This segmentation enables the sponge pads and other components to be easily removed for cleaning while maintaining manufacturing efficiency through standardized module assembly.
3Volume of moving object
If multiple springs are arranged closely together, then space utilization is improved, but independence of spring motion is worsened
Solution Approach 1:
Each spring is housed in its own independent module with separate base and end cover, preventing mutual interference between adjacent springs. The locking structures connect modules while maintaining their independence, allowing springs to move freely without affecting neighboring springs even when closely arranged.
Solution Approach 2:
The base and end cover act as intermediary structures that isolate each spring within its own module. These components prevent direct contact between adjacent springs, ensuring independent motion while allowing compact arrangement through standardized connection interfaces.
4Device complexity
If springs are positioned without external flexible connections, then structural simplicity is improved, but resistance to winding is worsened
Solution Approach 1:
Flexible straps are used as external connections between modules, providing flexibility that prevents spring winding while maintaining structural simplicity. The thin film-like straps allow natural spring movement without creating rigid constraints that could cause winding, yet provide sufficient connection to maintain overall structure.
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 system facilitates easy disassembly and reassembly, reduces storage space, provides better comfort through independent spring motion, and allows for easy cleaning of the sponge pad, addressing the challenges of existing integral spring cushions.
Implementation Method 1
a plurality of flexible straps, two ends of each flexible strap in the plurality of flexible straps being fixedly connected to the base and the end cover respectively
