Zipper Mattress Attachment for Adjustable Foundation Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mattresses often fall off or slide around on adjustable foundations over time, and existing solutions fail to provide a secure and aesthetically pleasing attachment mechanism.
Innovation Solution
A zipper mechanism is used to attach the mattress to the adjustable foundation, with zippers sewn into the seams of the mattress and foundation to ensure a strong and hidden connection, allowing the mattress to remain in place during articulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a zipper mechanism is used to attach the mattress to the adjustable foundation, then the mattress remains securely attached during articulation, but the device complexity increases
Solution Approach 1:
The patent introduces a zipper mechanism as an intermediary component between the mattress and adjustable foundation. The zipper includes a first zipper tape attached to the mattress and a second zipper tape attached to the foundation, with interlocking teeth that provide secure attachment while allowing for articulation movement. This intermediary solution resolves the contradiction by providing reliable attachment without requiring complex mechanical fastening systems.
Solution Approach 2:
The zipper tapes are attached to flexible seams on the mattress and foundation surfaces, allowing the attachment mechanism to flex and move with the articulation of the foundation. The thin film nature of the zipper tapes enables them to conform to the moving surfaces while maintaining secure attachment, resolving the contradiction between reliability and flexibility.
2Strength
If the zipper is sewn into the seams of the mattress and foundation, then the connection is strong and hidden, but the manufacturing precision requirements increase
Solution Approach 1:
The zipper tapes are pre-attached to the mattress and foundation during manufacturing, with the zipper mechanism positioned and secured before final assembly. This preliminary action ensures proper alignment and secure attachment, reducing the precision requirements during final assembly while maintaining strong hidden connections.
Solution Approach 2:
The zipper mechanism serves as an intermediary that bridges the mattress and foundation through their respective seams. The zipper teeth and tapes are designed to interlock securely within the seam structures, providing strong attachment while the seam itself conceals the zipper mechanism, balancing strength requirements with manufacturing feasibility.
3Reliability
If the zipper extends from the head end to the foot end of the mattress, then the mattress remains securely retained during articulation, but the length of the zipper increases
Solution Approach 1:
The zipper mechanism is segmented into two separate zipper tapes - a first zipper tape attached to the mattress and a second zipper tape attached to the foundation. These segmented tapes with interlocking teeth provide distributed attachment points along the length of the mattress, ensuring secure retention during articulation while allowing the zipper to be constructed from manageable segments rather than a single continuous piece.

AI summary
A system can include a zipper that connects a mattress to a bed foundation. For example, the zipper can extend from a head end to a foot end of an adjustable foundation. For another example, a zipper can connect to a mattress along a seam of the mattress and/or to a foundation along a seam of a foundation. For another example, a first zipper can connect the mattress core to a second zipper and the second zipper can connect a foundation to the first zipper. For another example, first and second zippers can be substantially vertically aligned.
