Bed Mattress Spring Structure With Z-Shaped Anti-Contact End
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed mattress springs experience rapid deformation and generate noise due to close contact between connection end portions and windings during load application, leading to lateral displacement and reduced lifespan.
Innovation Solution
A spring structure with a 'Z'-shaped contact-preventing/rigidity-reinforcing end at the connection portion between the body spring and exposure wire spring, preventing contact with uppermost or lowermost windings and enhancing rigidity to ensure vertical movement only, thereby reducing noise and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connection end portion is allowed to contact the uppermost winding for structural simplicity, then manufacturing is easier, but contact noise is generated and lifespan is reduced
Solution Approach 1:
The patent introduces a contact-preventing structure as an intermediary element between the connection end portion and the uppermost winding. This mediator prevents direct contact while maintaining the structural integrity and functionality of the spring assembly, thereby eliminating contact noise and extending lifespan without significantly complicating manufacturing.
2Stability of the object's composition
If the connection end portion is made rigid to prevent lateral displacement, then stability improves, but contact with windings occurs causing noise
Solution Approach 1:
The contact-preventing structure serves as a mediator that maintains the stability and rigidity of the connection end portion while preventing it from contacting the uppermost winding. This intermediary element allows the connection to remain stable and resistant to lateral displacement without generating contact noise.
3Adaptability or versatility
If the exposure wire spring is allowed to move freely, then cushioning flexibility is improved, but lateral displacement occurs reducing effectiveness
Solution Approach 1:
The contact-preventing structure acts as a guide and mediator that constrains the exposure wire spring to vertical movement only. By preventing lateral displacement through this intermediary structure, the spring maintains its vertical alignment while still providing flexible cushioning through vertical compression and expansion.

AI summary
Disclosed herein is a spring structure having a contact-preventing and rigidity-reinforcing function for a bed mattress in which the structure of a connection end portion for connecting a body spring and an exposure wire spring to each other is improved such that the connection end portion is not in close contact with an uppermost winding and/or a lowermost winding of the body spring and such that when a load is exerted to an exposure wire spring a displacement is prevented from being generated in which the exposure wire spring is leaned to one side, and rigidity of the spring is reinforced so that the exposure wire spring ascends/descends vertically only, thereby easily preventing the lateral displacement and deformation of the spring along with a prevention of a noise due to a frictional contact to prolong the lifespan of the spring.
