Mattress Spring Positioning Ring to Prevent Waist-Ring Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic mattresses with interconnected springs lack independent elasticity adjustment based on body posture, leading to uneven stress distribution and reduced comfort.
Innovation Solution
The springs are connected using a positioning ring and connecting waist rings, ensuring independent stress distribution by maintaining the stability and alignment of the springs through buckling and pin connections, with the positioning ring parallel or perpendicular to the spring's elastic force direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If springs are connected using connecting waist rings, then the springs can be connected together to form an elastic mattress, but the connecting waist ring and spring body may undergo relative displacement during use, affecting connection stability
Solution Approach 1:
The positioning ring is pre-installed on the spring body at a predetermined position (at least 1/4 length from the stressing end) before the connecting waist ring is attached. This preliminary positioning structure ensures that when the connecting waist ring is later fastened, it cannot undergo relative displacement along the spring body, thereby solving the connection stability issue while maintaining ease of manufacture
Solution Approach 2:
The positioning ring acts as an intermediary element between the spring body and the connecting waist ring. It provides a dedicated positioning interface that mediates the connection, preventing direct sliding contact between the connecting waist ring and spring body, thus ensuring connection stability without complicating the overall assembly process
2Strength
If upper ends of springs are connected together, then the springs can be jointly stressed to provide elastic force, but the springs cannot be independently stressed and separated, preventing synchronous deformation with body posture
Solution Approach 1:
The spring system is segmented into individually connected units through the connecting waist rings and positioning rings. Each spring maintains its independence while being connected to neighbors, allowing each spring to be independently stressed and deform synchronously with body posture changes, while still providing collective elastic support

AI summary
One or more springs having at least one positioning ring and an elastic mattress are provided. Each of the one or more springs comprises a spring body having a spiral shape formed by winding, two ends of the spring body are wound to form two end surface rings, the spring body comprises the at least one positioning ring, the at least one positioning ring is a winding ring of the spring body, the at least one positioning ring is substantially parallel to the two end surface rings or is substantially perpendicular to a direction of an elastic force of the spring body, and the winding ring is at least spaced apart from a stressing end for 1/4. In the present disclosure, the spring body comprises the at least one positioning ring, and the at least one positioning ring is a winding ring of the spring body. A length of the at least one positioning ring extends no less than 180 degrees. The at least one positioning ring is substantially parallel to the two end surface rings or is substantially perpendicular to the direction of the elastic force of the spring body, so as to position the one or more connecting waist rings in subsequent assembly processes to effectively prevent displacement of the one or more connecting middle rings during use, and convenience and stability of the connection between the springs is improved.
