Spring module and spring cushion for furniture
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 their integral design.
Innovation Solution
A spring module system comprising conical springs and flexible straps allows for easy assembly and disassembly, with a sponge pad that is detachable for cleaning, enabling the spring modules to be stacked and nested for space-saving storage and providing independent compressing and releasing motions for improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing spring mattresses are designed as integral non-disassemble cushions, then the structure is simple and stable, but the furniture is difficult to disassemble, transport, and store
Solution Approach 1:
The spring mattress is divided into multiple independent spring modules, each containing a conical spring, flexible straps, and a base. These modules can be separately assembled and disassembled, allowing the furniture to be easily transported and stored while maintaining structural stability through the standardized modular design.
2Ease of operation
If existing spring mattresses are designed as integral products, then the structure is stable, but the sponge part cannot be removed for cleaning
Solution Approach 1:
The mattress structure is segmented into spring modules and a separate sponge layer. The sponge part can be completely removed from the spring modules for cleaning or replacement, while the spring modules remain assembled. This separation allows easy maintenance without requiring disassembly of the entire mattress structure.
3Ease of operation
If independent bagged spring 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:
Flexible straps replace the traditional non-woven fabric covering. These straps are positioned outside the conical spring and connected to the base, allowing the spring to move up and down independently without being constrained by adhered fabric. The straps provide necessary structural support while maintaining spring independence for comfort.
4Ease of operation
If existing bed mattresses are large in size, then they provide sufficient comfort, but they are not easy to disassemble and store
Solution Approach 1:
The spring modules are designed with nested structures where the conical spring fits within the base, and flexible straps are positioned outside the spring. This nested arrangement allows the modules to be compactly stored when not in use, significantly reducing storage space requirements while maintaining the necessary comfort characteristics when assembled.
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, enhances cleaning capabilities, and provides better comfort by allowing independent motion of springs, addressing the challenges of existing integral spring mattresses.
Implementation Method 1
a conical spring; the spring in the spring module is not easy to be wound together with springs or other components in adjacent spring modules
Implementation Method 2
a plurality of flexible straps. Each flexible strap respectively comprises: a strap-like main body part, the main body part comprising a first end a second end opposite to the first end along a length direction of the flexible strap; a first hook, positioned at the first end of the main body part; and a second hook, positioned at the second end of the main body part
