Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible magnetic strips are unable to provide a sealing that is stable to various mechanical deformations such as bending and twisting, due to non-proximate distance between magnetic elements and the mechanical characteristics of the materials used.
Innovation Solution
A sealable device with a magnetic sealing closure is designed, featuring membranes with a predetermined thickness and static friction coefficient that preserves magnetic attraction and prevents movement, ensuring stability under mechanical deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible magnetic strips are used for sealing, then the sealing is flexible and can be deformed, but the magnetic attraction force is reduced due to non-proximate distance between magnetic elements
Solution Approach 1:
The patent uses thin membrane structures (first and second membranes) that connect the magnetic strips, allowing the sealing to remain flexible while maintaining proximity between magnetic elements. The membranes act as thin flexible barriers that do not significantly increase the distance between magnetic elements when the sealing is deformed, thus preserving magnetic attraction force while enabling flexibility.
Solution Approach 2:
The patent introduces a third dimension by using membranes with optimized thickness parameters. The membranes extend in the direction perpendicular to the magnetic strip surfaces, creating a three-dimensional structure that maintains magnetic element proximity while allowing flexibility in other dimensions. This dimensional approach resolves the contradiction between flexibility and magnetic force.
2Adaptability or versatility
If flexible magnetic strips are used for sealing, then the sealing can be deformed, but the sealing becomes unstable under mechanical deformations such as bending and twisting
Solution Approach 1:
The thin membrane structure provides flexibility for deformation while the magnetic attraction between elements maintains structural integrity. The membranes are thin enough to allow deformation but provide sufficient structural support to maintain sealing stability during bending and twisting operations.
Solution Approach 2:
The patent accommodates curved and deformed configurations through its flexible membrane design, allowing the sealing to adapt to various shapes while maintaining functional integrity. The structure can bend and twist without compromising the sealing relationship between magnetic elements.
3Force
If strong magnetic elements are embedded in flexible strips, then magnetic attraction force is increased, but the mechanical characteristics of the materials are compromised
Solution Approach 1:
The patent creates a composite structure combining strong magnetic elements with flexible membrane materials. The first and second membranes are connected to the magnetic strips, forming a composite assembly that leverages the strengths of both components: the magnetic elements provide strong attraction force while the membranes provide mechanical flexibility and strength.
Solution Approach 2:
The thin membrane structure distributes mechanical stresses away from the magnetic elements, protecting them from damage while maintaining their magnetic properties. The membranes act as protective yet flexible enclosures that preserve both mechanical integrity and magnetic functionality.
