Pocket Spring Core Reinforcement Strips for Longitudinal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pocket spring cores lack dimensional stability, particularly in the longitudinal direction, due to unstable connections between spring strands, leading to handling issues and increased production costs when attempting to address this with external reinforcement frames.
Innovation Solution
Incorporating buckling-resistant reinforcement strips made of flexible materials, such as textile or plastic, which are attached to the spring strands via gluing or form fit, extending over the entire length and positioned between adjacent strands to enhance stability without affecting suspension behavior, and using a flexible band to cover gaps and replace intermediate foam layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If peripheral reinforcement frames are attached to the pocket spring core, then dimensional stability is improved, but device complexity and production costs increase
Solution Approach 1:
The invention extracts the reinforcement function from the external peripheral frame and relocates it directly to the spring strands through attached reinforcement strips. This eliminates the need for separate peripheral reinforcement structures and their complex attachment processes, while maintaining dimensional stability.
Solution Approach 2:
The reinforcement strips are merged with the spring strands through direct attachment, combining the structural support function with the existing spring assembly. This integration eliminates separate production steps for attaching peripheral frames and simplifies the overall manufacturing process.
2Stability of the object's composition
If peripheral reinforcement frames are attached to the pocket spring core, then dimensional stability is improved, but production costs increase
Solution Approach 1:
The reinforcement function is extracted from expensive peripheral frames and implemented through simpler, cheaper reinforcement strips directly attached to spring strands, reducing material and manufacturing costs while maintaining stability.
3Stability of the object's composition
If reinforcement frame is attached in the area of the lying surface, then dimensional stability is improved, but lying comfort deteriorates due to unwanted influence on suspension behavior
Solution Approach 1:
The reinforcement strips are selectively positioned at specific locations on the spring strands rather than forming a continuous peripheral frame. This localized reinforcement provides dimensional stability while leaving the suspension characteristics in the lying surface area largely unaffected.
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 solution provides cost-effective dimensional stability for pocket spring cores, integrates reinforcement attachment into the production process, reduces material usage, and maintains lying comfort by minimizing the impact on suspension behavior, thus optimizing manufacturing efficiency and cost-effectiveness.

AI summary
The pocket spring core has multiple spring strands (1), which lie next to each other and are connected with each other. The spring strands form a lying surface. Each spring strand has multiple springs, which are arranged behind one another in a row and are covered by a case (2) made of textile material in each case. A buckling-resistant reinforcing strip (4) is fastened to a spring strand. The reinforcing strip is connected with the spring strand in a form-fit manner, particularly by joggling. The reinforcing strip is made of plastic or wood.
