Magnetic Locking Pin for Wheeled Luggage Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to securely attach auxiliary items to pull-handle wheeled luggage, leading to sliding, twisting, and theft issues, while being cumbersome and time-consuming to attach and detach.
Innovation Solution
A magnetic locking device system with a magnetic locking pin controlled by an operating button, a locking pin hole, and an auxiliary item attachment adaptor, allowing for quick and secure attachment and detachment of auxiliary items to the pull-handle of wheeled luggage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a strap is used to attach the auxiliary item to the pull-handle, then the auxiliary item can be secured to the luggage, but the attachment process becomes cumbersome and time-consuming requiring two hands
Solution Approach 1:
The patent replaces the traditional mechanical strap system with a magnetic locking mechanism. The magnetic locking pin creates a magnetic field that automatically secures the auxiliary item to the pull-handle without requiring manual threading or fastening of straps, thus maintaining attachment security while dramatically improving ease of operation
Solution Approach 2:
The magnetic locking system enables self-service attachment where the auxiliary item with its attachment adaptor automatically engages with the magnetic locking pin when placed on the luggage. The magnetic attraction self-aligns and secures the connection without requiring user manipulation of straps or fasteners
2Reliability
If a strap is used to attach the auxiliary item, then the item can be secured, but rapid movements and quick turns cause the auxiliary item to slide or twist away from its desired position
Solution Approach 1:
The magnetic locking mechanism replaces the flexible strap system that allowed sliding and twisting. The magnetic field creates a stable, fixed-position connection between the auxiliary item and pull-handle that maintains consistent alignment during rapid movements and turns, eliminating position instability while maintaining security
3Stability of the object's composition
If support bars are added to prevent twisting, then the auxiliary item can be secured, but the device complexity increases and additional parts become intangled with straps
Solution Approach 1:
The magnetic locking system eliminates the need for mechanical support bars and additional structural components. The magnetic field itself provides the stabilizing force that prevents twisting and maintains position, thereby reducing device complexity and eliminating the problem of additional parts becoming entangled with straps
Solution Approach 2:
The invention extracts and removes the unnecessary support bars and complex structural elements from the system. By using magnetic force alone, the patent eliminates these extraneous components that added complexity and caused entanglement issues, keeping only the essential magnetic locking mechanism

AI summary
A magnetic connection system for luggage or other bags. This invention involves a method for manufacturing and using a magnetic locking device system for attaching a bag to a pull-handle or other telescoping tubular device of a wheeled bag. This system allows two bags to easily be secured together, quickly and efficiently while a traveler is on the go. If the traveler wishes to remove the second bag from the wheeled luggage, they merely need to depress the release button on the pull-handle thus removing the magnetic force which connects the two bags together through the connection with the locking pin, the mount and the auxiliary attachment adaptor.
