Solution Overview
Problem
Existing mattress sets face challenges in secure fixation to prevent movement and tearing, particularly in hospital environments where frequent changes and contamination are common, leading to inefficient installation and maintenance.
Innovation Solution
The use of reversible magnetic strips on the contact faces of the mattress and box spring for secure attachment, providing a larger gripping surface and easier installation while allowing for the use of protective or safety fitted sheets without affecting the fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connecting means (zippers, hook and loop systems, buttons) are used to secure the mattress to the bed base, then the mattress can be fastened to the bed base, but the positioning requires precise alignment resulting in slow and tedious setup operation
Solution Approach 1:
The patent replaces traditional mechanical connecting means (zippers, hooks, buttons) with magnetic strips that utilize magnetic attraction forces. This substitution eliminates the need for precise manual alignment and complex fastening operations while maintaining secure attachment. The magnetic strips automatically align and secure the mattress to the bed base through magnetic attraction, significantly reducing setup time and operational complexity.
Solution Approach 2:
The patent changes the fundamental parameter of connection from mechanical interlocking to magnetic field interaction. By using magnetic strips with appropriate strength and positioning, the system achieves reliable securing without requiring precise positioning. The magnetic force provides continuous holding power that is independent of alignment precision, resolving the contradiction between ease of operation and securing reliability.
2Adaptability or versatility
If traditional connecting means are used to secure the mattress, then the mattress can be fastened to the bed base, but the connecting means affect or prevent the fitting of safety fitted sheets necessary in hospital settings
Solution Approach 1:
The patent segments the connection system into separate magnetic strips positioned at the periphery of the mattress and bed base. This segmentation allows the magnetic connecting means to be located at the edges while leaving the central mattress surface completely accessible for fitting safety sheets. The magnetic strips provide secure connection without interfering with the placement and functionality of protective hospital bedding.
Solution Approach 2:
The magnetic strips act as intermediary connecting elements that bridge the mattress and bed base without requiring direct contact or interference with the mattress surface. This intermediary positioning allows safety fitted sheets to be placed over the mattress surface while the magnetic strips maintain their connecting function at the edges, achieving both adaptability and connection integrity.
3Stability of the object's composition
If the mattress is securely fastened to prevent shifting and accidental removal, then the mattress stability is improved, but the setup operation becomes slow and tedious due to precise positioning requirements
Solution Approach 1:
The patent replaces precision-dependent mechanical fastening systems with magnetic attraction-based connection. The magnetic strips provide stable securing through magnetic forces that automatically engage without requiring precise manual positioning. This substitution maintains mattress stability while dramatically reducing setup time, as the magnetic connection forms immediately upon proximity rather than requiring aligned fastening operations.
Solution Approach 2:
The magnetic strips enable self-aligning and self-securing functionality. When the mattress is placed near the bed base, the magnetic attraction automatically pulls them into proper alignment and secures them together without requiring manual positioning or adjustment. This self-service mechanism achieves both stability and time efficiency by eliminating the need for operator intervention in precise positioning.
