Magnetic Closure with Spaced Magnet and Retention Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic closures for bags and rucksacks require precise alignment of magnets for effective closure, making it difficult for users to close them without careful positioning of the flaps.
Innovation Solution
A magnetic closure design featuring a male and female element with magnets spaced from the flap surfaces, where the female element has a protruding retention element to accommodate the male element at right angles, allowing for easier alignment and providing an acoustic prompt for closure confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnets are arranged mutually closer precisely on each flap, then magnetic attraction strength is improved, but alignment precision requirement increases
Solution Approach 1:
The patent introduces a non-magnetic plate as an intermediary carrier between the magnet and the flap surface. This plate allows the magnet to be positioned at an optimized distance from the flap without requiring precise alignment during closure operations. The non-magnetic plate acts as a mediator that decouples the magnetic force optimization from the alignment precision requirement.
Solution Approach 2:
The patent transitions from a two-dimensional surface alignment problem to a three-dimensional spatial arrangement by spacing the magnet from the flap surface. This vertical dimensionality allows the magnet to be positioned optimally for magnetic attraction while the non-magnetic plate handles the alignment function, separating the two functions across different spatial dimensions.
2Ease of operation
If magnets are spaced from the flap surface, then ease of operation is improved, but magnetic attraction strength may be reduced
Solution Approach 1:
The non-magnetic plate serves as a mediator that allows the magnet to be spaced from the flap surface, improving ease of operation by eliminating the need for precise alignment. The plate maintains sufficient magnetic attraction strength while enabling the magnet to be positioned at an optimal distance for easy closure operation.
Solution Approach 2:
The patent changes the spatial parameter by spacing the magnet from the flap surface rather than placing it in direct contact. This parameter change improves ease of operation while the non-magnetic plate ensures magnetic attraction strength is maintained at acceptable levels for effective closure.
3Ease of manufacture
If conventional magnetic closure design is used, then manufacturing simplicity is maintained, but user operation difficulty increases
Solution Approach 1:
The patent segments the closure system into distinct functional components: a non-magnetic plate for alignment and a magnet for magnetic attraction. This segmentation allows each component to perform its specific function optimally, maintaining manufacturing simplicity while significantly improving ease of operation through the specialized roles of each component.
Solution Approach 2:
The non-magnetic plate acts as an intermediary component that simplifies the operation of the closure system. It handles the alignment function, allowing users to close the bag without worrying about precise magnet positioning, while the magnet maintains its primary function of providing magnetic attraction.
