Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pocket spring mattresses are difficult to compress and roll due to their unstable size, leading to high transportation and storage costs, and the added steel wire or sponge frames are not easily recyclable.
Innovation Solution
A device and method for manufacturing a pocket spring bed net that uses a supply mechanism for sheet-like flexible materials, a spring string conveying mechanism, a glue spraying mechanism, and a pushing mechanism to bond the flexible materials with pocket spring strings, allowing for dimensional stability and ease of compression and rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual springs are compressed and pocketed to form independent pocket spring strings, then each spring body works independently providing supporting role and comfort, but the manufactured spring mattress has large stretch stroke or compression stroke leading to unstable size
Solution Approach 1:
The patent uses a net-like structure (flexible shell/film) to wrap around and constrain the pocket spring strings. This net structure allows the springs to function independently while preventing excessive stretching or compression of the overall mattress, thus maintaining size stability without compromising spring independence
Solution Approach 2:
The patent combines pocket spring strings with a net-like restraining structure to create a composite mattress system. This composite structure integrates the flexibility and independence of individual springs with the dimensional stability provided by the net constraint mechanism
2Stability of the object's composition
If steel wire frame or sponge frame is added around mattress to fix size, then mattress size stability is improved, but the mattress cannot be rolled and steel wire frame cannot be compressed
Solution Approach 1:
The patent replaces rigid steel wire frames and bulky sponge frames with a flexible net-like structure. This net structure can conform to compressed and rolled shapes while still providing dimensional constraints, enabling the mattress to be rolled for transportation and storage without sacrificing size stability when in use
Solution Approach 2:
The net-like structure is designed to be dynamically adaptable - it maintains structural integrity and size stability during normal use, but can be deformed into compressed or rolled configurations when needed for transportation or storage, providing both stability and adaptability
3Stability of the object's composition
If sponge frame is used to fix mattress size, then size stability is improved, but sponge degradation and recycle become problems when mattress is abandoned
Solution Approach 1:
The patent employs a net-like structure that is more environmentally friendly and recyclable compared to sponge frames. The net structure can be made from durable, recyclable materials that do not degrade like sponge, reducing harmful environmental factors when the mattress is abandoned
Solution Approach 2:
The net-like restraining structure is designed to be recoverable and recyclable, unlike degradable sponge frames. This allows the structural component to be recovered and reused or properly recycled at the end of the mattress lifecycle, eliminating the harmful degradation issues associated with sponge frames
