Modular Spring Cushion Design 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 challenging for transportation and storage, and the integrated spring cushions are not easily cleanable, affecting comfort and hygiene.
Innovation Solution
A spring module design featuring conical springs and flexible straps allows for easy assembly and disassembly, with a sponge pad that is detachable for cleaning, enabling independent compression and release of springs for improved comfort and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spring cushion is made as an integrated non-disassemble structure, then the manufacturing process is simplified, but the ease of disassembly and storage is worsened
Solution Approach 1:
The spring cushion is divided into multiple independent modules, each containing a spring unit with its own support plate and connecting components. These modular units can be easily assembled and disassembled while maintaining the overall cushion structure, thus improving ease of disassembly and storage without significantly complicating the manufacturing process.
2Stability of the object's composition
If the spring cushion is made as an integrated structure, then the structural stability is improved, but the ease of transportation and storage is worsened
Solution Approach 1:
The modular spring cushion units are designed to nest within each other when disassembled, with smaller components fitting into the spaces of larger components. This nesting arrangement significantly reduces the storage and transportation volume while maintaining structural stability when assembled, as each module retains its integrity during storage.
3Ease of manufacture
If the sponge part is integrated with the spring structure, then the manufacturing process is simplified, but the ease of cleaning is worsened
Solution Approach 1:
The sponge cleaning function is extracted from the integrated structure by making the sponge pad a separate, removable component. The sponge pad can be detached from the spring module for cleaning while the spring mechanism remains in place, thus improving ease of cleaning without significantly complicating the manufacturing process.
4Stability of the object's composition
If non-woven fabrics are adhered together to cover bagged springs, then the structural integrity is improved, but the independence of spring movement is worsened
Solution Approach 1:
Instead of using a continuous adhered fabric covering that restricts spring movement, the design uses localized support plates and individual fabric covers for each spring unit. This allows each spring to move independently while maintaining structural integrity through the modular connection system, thus improving spring independence without sacrificing structural stability.
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 provides a stable and comfortable cushion with adjustable stiffness, easy cleaning, and reduced storage space requirements, addressing the challenges of disassembly, transportation, and hygiene in existing furniture designs.
Implementation Method 1
a conical spring; and a plurality of flexible straps... 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
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
