Modular Spring Bracket Assembly for Disassembleable Furniture Cushions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large furniture, such as beds, is difficult to disassemble and reassemble, making it cumbersome for frequent migration and outdoor use. Additionally, existing spring cushions are integral, non-disassembleable, and hard to clean, affecting comfort and hygiene.
Innovation Solution
A spring module for a spring cushion that consists of conical springs and a spring bracket with flexible straps, allowing for easy assembly and disassembly. The spring module can be compressed or stacked, saving space, and features a detachable sponge pad for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing spring cushions are made as integral, non-disassembleable units, 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 individually assembled and disassembled while maintaining the overall cushion structure. The segmentation allows the cushion to be taken apart for storage or migration while preserving structural integrity during use.
2Volume of moving object
If spring modules are stacked and nested for storage, then storage space is reduced, but spring interference between modules may increase
Solution Approach 1:
The spring modules are designed to be nested within each other during storage, with smaller modules placed inside larger ones. This nesting arrangement significantly reduces storage space requirements while the individual encapsulation of each spring in its own module prevents interference between springs from different modules.
Solution Approach 2:
Flexible straps serve as intermediary elements that connect the springs to the base and end cover without allowing direct contact between springs of adjacent modules. These straps maintain spring independence even when modules are stacked or nested, preventing mutual interference while allowing compact storage.
3Force
If non-woven fabrics are used to cover bagged springs, then spring support is improved, but spring independence and comfort are worsened due to adhesion
Solution Approach 1:
The patent replaces permanent adhesive bonds with removable flexible straps that can be easily attached and detached. These straps provide the necessary support force while allowing individual springs to move independently without being constrained by adhesive materials, enabling both support and independence.
4Stability of the object's composition
If the sponge part is integrated into the bed mattress, then structural integrity is improved, but ease of cleaning is worsened
Solution Approach 1:
The sponge pad is segmented from the spring modules and made detachable, allowing it to be removed separately for cleaning while the spring modules remain in place. This segmentation maintains structural integrity during use by keeping all components together, but enables easy cleaning by separating the sponge portion that requires frequent 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
The spring module enables the spring cushion to be easily disassembled, stored, and transported, while maintaining stability and comfort. The detachable sponge pad ensures better hygiene, and the independent compressing motion of each spring module enhances comfort.
Implementation Method 1
one or more conical springs, and a spring bracket configured to hold and fix the one or more conical springs

AI summary
A spring module includes a spring and a spring bracket for accommodating the spring. The spring bracket may have a base, an end cover and a flexible connecting part connecting the base and the end cover. The spring may be fixed in the spring bracket with a predetermined initial pressure. The spring module may be used in a spring cushion for furniture.
