Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bed systems often require cumbersome screws and bolts to secure mattresses to frames, making installation and use difficult, and can result in mattresses sliding or bunching against walls.
Innovation Solution
The use of magnetic couplers with a two-component assembly, including a magnet assembly attachable to the mattress and a target assembly attachable to the bed foundation, providing a quick, simple, and reliable attachment and detachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and bolts are used to secure the mattress to the frame, then the mattress is firmly attached, but the installation and operation become cumbersome and difficult
Solution Approach 1:
The patent replaces the traditional mechanical screw and bolt fastening system with a magnetic coupling system. The magnetic couplers use magnetic attraction forces to securely attach the mattress to the frame, eliminating the need for manual manipulation of screws and bolts. This substitution maintains reliable attachment while dramatically improving ease of operation, as the magnetic couplers can be easily attached and detached without tools.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical interlocking (screws and bolts) to magnetic field interaction. By utilizing magnetic field strength as the attachment parameter, the system achieves both secure attachment and easy operation. The magnetic force can be sufficiently strong to hold the mattress securely during normal use, yet allows for simple attachment and detachment when needed.
2Ease of operation
If the mattress is left unsecured on the frame, then installation is simple, but the mattress slides off or bunches together over time
Solution Approach 1:
The patent replaces complex mechanical fastening systems with magnetic coupling to achieve both simplicity and stability. The magnetic couplers provide continuous holding force that prevents the mattress from sliding or bunching, while requiring minimal installation effort compared to traditional screw and bolt systems.
Solution Approach 2:
The magnetic couplers automatically maintain the mattress position through continuous magnetic attraction. Once attached, the magnetic force continuously counteracts any forces that might cause sliding or bunching, providing self-regulating position stability without requiring additional mechanical constraints or adjustments.
3Reliability
If traditional fastening methods are used, then the mattress is securely attached, but the complexity of the device increases
Solution Approach 1:
The patent replaces complex mechanical fastening systems involving multiple components (screws, bolts, washers, drill holes) with simpler magnetic couplers. The magnetic coupling system reduces the number of parts and assembly steps while maintaining secure attachment, thereby reducing overall device complexity.
Solution Approach 2:
The patent divides the attachment function into separate magnetic coupler units distributed at different locations on the mattress and frame. This segmentation allows each coupler to be a simple, standardized component, reducing the complexity of individual parts and simplifying the overall system architecture compared to a unified mechanical fastening system.

Function Achieved in This Case
The magnetic couplers securely attach and detach the mattress from the foundation without the need for screws, preventing sliding and bunching, while allowing for easy adjustment and disassembly, enhancing user convenience and mattress longevity.
Implementation Method 1
The magnet assembly and the target assembly can be releasably attached when the magnet is magnetically coupled to the target

AI summary
A magnetic coupler for attaching a mattress to a bed foundation includes a magnet assembly, a target assembly, and a shunt. The magnet assembly includes a housing and a magnet, wherein the housing is configured to couple the magnet to the mattress. The target assembly is configured to couple a target to the foundation. The shunt is disposed within the housing of the magnet assembly or in the mattress. The magnet assembly and the target assembly are releasably attached when the magnet is magnetically coupled to the target.
