Locking Fastener System with Asymmetric Magnetic Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener systems allow for generic attachments, limiting manufacturers' ability to provide exclusive customization for their products, as they can be used with goods from different manufacturers, reducing the uniqueness of the attachments.
Innovation Solution
A two-piece locking fastener system comprising a magnetic key and housing with varying slot widths and a magnet for secure locking, allowing for exclusive customization by enabling the attachment of only manufacturer-specific items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If generic hooks are used for attachments, then ease of operation and versatility are improved, but product uniqueness and manufacturer exclusivity deteriorate
Solution Approach 1:
The fastener system employs asymmetric geometry where the key has a specific prong configuration that matches only the corresponding housing slot geometry. The slot width varies along its length with a narrow portion that only accommodates the key's prong in a specific orientation and position, preventing generic or substituted goods from being attached while maintaining ease of operation for authorized attachments.
2Reliability
If a locking mechanism with varying slot width is used, then reliability and manufacturer exclusivity are improved, but device complexity increases
Solution Approach 1:
The housing slot features a dynamic width variation along its length, transitioning from a wider opening that allows key insertion to a narrower locking portion that secures the key in place. This dynamic geometry change provides reliable locking security through the narrow portion while maintaining relative structural simplicity by using a continuous slot rather than multiple discrete components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables manufacturers to provide exclusive customization options by ensuring that only approved items can be attached, enhancing product uniqueness and design flexibility.
Implementation Method 1
The locking location has a magnet to provide attraction between the key and the housing, providing the locking of the mechanism.
