Modular Spring Cushion with Detachable Units for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture, such as beds and mattresses, are difficult to disassemble, transport, and clean, and lack independent spring movement for comfort, leading to space inefficiency and health risks.
Innovation Solution
A spring module with a base and end cap design that allows for easy assembly and disassembly, featuring a flexible connection and locking mechanism to stabilize the spring, enabling independent compression and release, and a detachable sponge layer for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integral spring cushion design is used, then the structure is simple and stable, but it is difficult to disassemble and store
Solution Approach 1:
The spring cushion is divided into multiple independent spring units, each enclosed in a separate bag. These modular units can be individually removed and reassembled, transforming the integral structure into a segmented system that enables easy disassembly and storage while maintaining overall structural stability through the coordinated arrangement of multiple springs.
Solution Approach 2:
The spring units are arranged in a nested configuration where multiple springs are positioned within the same cushion space, allowing them to be compactly stored when removed from the cushion. This nesting approach enables the disassembled components to occupy minimal storage space while reconstructing the full cushion functionality when assembled.
2Ease of operation
If independent bagged springs are used, then individual spring movement is improved, but non-woven fabric covering restricts complete independence
Solution Approach 1:
Each spring is enclosed in a flexible bag made of elastic material that can deform and move with the spring. This flexible enclosure allows the spring to move up and down independently within its bag, while the bag itself provides protection and maintains the spring's position. The flexibility of the bag material ensures it does not restrict spring motion, thereby achieving both spring independence and comfort performance.
3Ease of operation
If the sponge layer is integrated, then the structure is stable, but it is difficult to clean
Solution Approach 1:
The sponge layer is divided into multiple detachable sponge pieces, each corresponding to a spring unit. These segmented sponge pieces can be individually removed from the cushion for cleaning while the base structure remains intact. This segmentation enables easy cleaning of the sponge components without compromising the overall structural stability when reassembled.
Solution Approach 2:
The detachable sponge pieces can be removed, cleaned, and reused multiple times. When the sponge pieces become worn or soiled, they can be discarded and replaced with new ones, while the main cushion structure is retained and reused. This approach maintains structural stability by preserving the base framework while allowing easy maintenance and cleaning of the removable sponge components.
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 compact storage and transportation, enhances comfort through independent spring movement, and allows for easy cleaning, addressing the limitations of existing furniture designs.
Implementation Method 1
a spring; a base having a first spring fixing portion and an end cap locking portion, the first spring fixing portion being configured to detachably fix a first end of the spring
Implementation Method 2
an end cap comprising: a cap body portion formed with a second spring fixing portion on a side facing the base, the second spring fixing portion being configured to detachably fix a second end of the spring; a locking portion configured to unlockably lock with the end cap locking portion; and a flexible connection portion connecting the cap body portion to the locking portion and located inside the spring in a radial direction of the spring

AI summary
A spring module for a spring cushion for furniture. includes a base (20), an end cap (30) and a spring (10) arranged between the base and the end cap. The end cap has a flexible connection portion (33) and is configured to be detachably fixed to the base (20). The flexible connection portion (33) is located radially inside the spring (10). The spring module provides improved stability. The spring cushion has a simple structure and is easy to assemble and disassemble. The disassembled spring modules can be compressed or stacked and nested to save storage and transportation space
