Pocket spring string, pocket spring mattress core, and mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pocket springs are difficult to separate and recycle due to their structure, requiring mechanical assistance or high-pressure water cutting, resulting in low work efficiency and high recycling costs.
Innovation Solution
A pocket spring design featuring springs wrapped in cloth with ultrasonic welds and detachable thread stitching at the top and bottom of each pocket, allowing for easy separation of springs and cloth without special technical means, using polypropylene cloth and glue for efficient recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional pocket springs are formed by wrapping springs in folded cloth with ultrasonic welds, then the springs are securely held in pockets, but the cloth and spring cannot be separated easily requiring mechanical assistance or high-pressure water cutting
Solution Approach 1:
The pocket spring structure is divided into separate components: the spring, the cloth pocket, and the stitching thread. This segmentation allows the spring to be independently extracted from the cloth by simply removing the stitching thread, eliminating the need for mechanical assistance or high-pressure water cutting while maintaining secure holding during use.
2Reliability
If traditional pocket springs require mechanical assistance or high-pressure water cutting for separation, then secure bonding is achieved, but work efficiency is low and recycling cost is high
Solution Approach 1:
The stitching thread is extracted as a separate, removable component that connects the spring to the cloth pocket. This extraction approach allows the spring to be easily removed from the cloth by simply taking out the thread, achieving reliable bonding during use while enabling high-efficiency recycling without mechanical assistance or high-pressure water cutting.
3Ease of operation
If detachable thread stitching is used to package springs in pockets, then easy separation and recycling are enabled, but additional manufacturing step is required
Solution Approach 1:
The stitching thread serves as an intermediary element that connects the spring to the cloth pocket. This intermediary approach enables easy separation and recycling by simply removing the thread, while the manufacturing process remains relatively simple as it only requires standard stitching operations in addition to the pocket formation process.
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
Enables quick and efficient separation of metal springs and cloth, facilitating manual operation and effective material recycling, particularly beneficial for environmental protection and garbage classification.
Implementation Method 1
Traditional pocket springs are formed by wrapping springs in folded cloth and forming ultrasonic welds on the cloth

AI summary
A pocket spring string, a pocket spring mattress core and a mattress. The pocket spring string includes: springs; cloth, which is folded and provided with welds to form multiple adjacent pockets, each pocket being provided with an opening, and the springs being received in the pockets respectively; and thread provided to stitch the openings so that the springs are packaged in the pockets in a compressed state. The pocket spring mattress core is formed by connection of the pocket spring strings, and the mattress includes a mattress cover and the pocket spring mattress core. Because the top and/or bottom of each pocket is provided with the opening which is stitched by the thread, when the thread is removed, the springs can be quickly separated from the pockets, so that the metal material and the cloth are separated without any special technical means.
