Problem
Existing spring cushions for furniture, such as beds, are difficult to disassemble and reassemble, occupy large storage space, and are challenging to clean, affecting comfort and practicality.
Innovation Solution
A modular spring cushion design featuring detachable spring modules with a base and flexible connecting parts, allowing for independent compression and release, and a detachable sponge pad for easy cleaning, along with a compartmentalized outer cover for efficient storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If existing spring cushions are designed as integrated non-disassemble cushions, then the structure is simple and stable, but they are difficult to disassemble and store, occupying large storage space
Solution Approach 1:
The spring cushion is divided into multiple independent spring modules, each containing a spring, base cloth, and connecting parts. These modular units can be disassembled and stored separately, significantly reducing storage volume while maintaining structural stability when assembled
Solution Approach 2:
The spring modules are designed to nest within each other when disassembled, with smaller modules fitting into larger ones, creating a compact storage configuration that minimizes the volume occupied during transport and storage
2Reliability
If independent bagged spring bed mattresses are used, then mutual interference between users is avoided, but the non-woven fabrics cause springs to be adhered together, affecting comfort
Solution Approach 1:
The springs are extracted from the conventional bagged design and placed directly on base cloth without enclosing fabric bags. This eliminates the adhesion problem caused by non-woven fabrics while maintaining the independence of each spring through proper spacing and connection design
Solution Approach 2:
Instead of using thick non-woven fabric bags, the invention uses thin base cloth that allows springs to move independently without adhesion, providing better comfort while maintaining spring independence
3Device complexity
If traditional bed mattresses are designed with integrated sponge parts, then the structure is simple, but the sponge part cannot be removed for cleaning, creating health risks
Solution Approach 1:
The sponge pad is separated from the spring modules into a detachable component. This allows the sponge pad to be removed for cleaning while keeping the spring modules intact, improving cleanability without significantly increasing overall structural complexity
Solution Approach 2:
The connection between sponge pad and spring modules is designed to be dynamic and detachable, allowing easy removal and reattachment. This enables the sponge pad to be taken off for cleaning and put back, solving the hygiene issue while maintaining simplicity
4Adaptability or versatility
If spring cushions are designed for frequent disassembly and reassembly, then mobility needs are met, but the complexity of disassembly and reassembly increases
Solution Approach 1:
The spring cushion is segmented into standardized spring modules with uniform connection interfaces. This modular design simplifies disassembly and reassembly operations, making the process more manageable despite the frequency of moves
Solution Approach 2:
Multiple spring modules are designed to connect through simple interfacing mechanisms, allowing them to be quickly assembled together. The connection design merges the modules into a stable structure through straightforward fastening methods
