Elastic module and elastic pad for furniture
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 integrated spring cushions are not easily disassembled or cleaned, affecting comfort and hygiene.
Innovation Solution
A spring module design featuring a base, end cover, and flexible connecting parts that allow for easy assembly and disassembly, with a rotary locking assembly for compressing springs, enabling independent motion and easy cleaning of the sponge part, and allowing modules to be stacked for space-saving storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spring cushions are made as integrated non-disassemble 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 easily assembled and disassembled while maintaining structural stability when connected, resolving the contradiction between integrated stability and ease of disassembly.
2Reliability
If independent bagged springs are covered with non-woven fabrics and foam rubber, then spring independence is improved, but ease of disassembly and transport is worsened
Solution Approach 1:
Each spring is enclosed in an independent bagged structure with base and end cover, maintaining spring independence while allowing the entire module to be easily disassembled and transported, eliminating the contradiction between reliability and ease of operation.
Solution Approach 2:
The use of flexible connecting parts made from elastic bands or rubber materials allows the spring modules to be easily connected and disconnected while maintaining structural integrity, enabling easy disassembly and transport without compromising spring independence.
3Stability of the object's composition
If non-woven fabrics are adhered together to cover bagged springs, then structural integrity is improved, but spring independence and comfort are worsened
Solution Approach 1:
Flexible connecting parts made from elastic bands or rubber materials replace adhered non-woven fabrics, providing structural integrity while allowing springs to move independently, thus maintaining both structural integrity and spring independence.
4Stability of the object's composition
If the sponge part is integrated with the spring structure, then structural stability is improved, but ease of cleaning is worsened
Solution Approach 1:
The spring cushion is segmented into modular units with the sponge part made as a separate detachable component, allowing the sponge to be easily removed for cleaning while maintaining structural stability when assembled, resolving the contradiction between structural stability and ease of cleaning.
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 facilitates easy disassembly and reassembly of furniture, provides improved comfort through independent spring motion, and allows for efficient cleaning and space-saving storage, addressing the challenges of existing integrated spring cushions.
Implementation Method 1
one or more springs; and a spring bracket configured to be able to hold and fix the one or more springs
Implementation Method 2
a rotary locking assembly arranged on the base and the end cover; wherein, the base and the end cover are configured to be releasably locked together via the rotary locking assembly, so as to compress the one or more springs
