Motorcycle Case Locking Hinge With Magnetic Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle case hinges can accidentally disengage due to a mobile hook without locks or blockage, leading to unintended opening, which compromises security and stability.
Innovation Solution
A locking hinge with magnetic coupling means, comprising a magnet on the bottom part and a metal backing plate on the hook, ensures a secure and stable connection between the two components of the case, preventing accidental opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile hook is used without locks or blockage means, then the hinge structure remains simple and easy to operate, but the hook can accidentally rotate and disengage, causing the case to open unintentionally
Solution Approach 1:
The patent replaces the purely mechanical hook-and-plate connection with a magnetic coupling system. Magnets embedded in the bottom part and metal strips in the hook create magnetic attraction that prevents accidental disengagement while maintaining simple operation. This substitution of mechanical interlocking with magnetic field interaction resolves the contradiction between simplicity and reliability.
Solution Approach 2:
The patent changes the physical parameter of the connection force by introducing magnetic attraction. The magnetic force provides a continuous holding force that prevents the hook from rotating away, transforming the connection from purely geometric (mechanical) to electromagnetic. This parameter change enables reliable locking without adding complex mechanical locks or blockage means.
2Reliability
If locks or blockage means are added to the mobile hook, then the reliability and security of the case is improved, but the device complexity increases
Solution Approach 1:
Instead of adding mechanical locks or blockage means to the hook, the patent uses magnetic coupling between the bottom part and hook. This eliminates the need for additional mechanical locking components while achieving reliable case closure. The magnetic field provides continuous holding force without requiring complex mechanical interlocks.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary force between the bottom part and hook. Rather than direct mechanical contact and interlocking, the magnetic field acts as a mediator that provides attractive force to maintain case closure. This intermediary approach achieves reliability without increasing mechanical device complexity.
3Stability of the object's composition
If magnetic coupling means are added to the hinge, then the stability and security of the case is enhanced, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent applies magnetic coupling locally at specific points where the bottom part and hook interact. Magnets are embedded in the bottom part and metal strips in the hook at strategic locations to provide stable magnetic attraction. This localized application of magnetic coupling provides stability enhancement without requiring magnets throughout the entire structure, minimizing added complexity.

Function Achieved in This Case
The magnetic coupling provides a firm and secure locking mechanism that maintains the case in a closed position, enhancing stability and security while maintaining simplicity and economic feasibility.
Implementation Method 1
The bottom part 12 and the hook 18 are equipped with magnetic coupling means, which allow, in the closed or hooked configuration of the hinge 10, when said bottom part 12 and said hook 18 are arranged in parallel facing each other (figure 3), firm and secure hooking of the second component onto the first component 14 to be maintained.

AI summary
A locking hinge (10) is described of the type comprising one bottom part (12), to be affixed to a first component (14) by means of suitable fastening means (16), and a hook (18), hinged to said bottom part (12) and provided with a hook-shaped end portion (20) for hooking a second component and blocking it in a closed position on the first component (14). The bottom part (12) and the hook (18) are equipped with magnetic coupling means (22,24), which allow, in the closed or hooked configuration of the hinge (10), when said bottom part (12) and said hook (18) are arranged in parallel facing each other, to maintain a firm and secure hooking of the second component onto the first component (14). The first component (14) and the second component typically consist of the two half-shells of a case or of a top box for motorcycles.
