Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupling devices for bicycle mudguards are inconvenient to reassemble after safety release, requiring precise alignment of separated parts, and do not ensure safe automatic separation from the strut when clothing is caught.
Innovation Solution
A magnetic coupling device comprising a first and second seat, a magnetic unit, and a rotatable releasing member that converts between linked and released positions, allowing easy separation and reassembly by magnetic attraction and cam mechanisms, ensuring safety release without manual alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coupling devices are used to link mudguard and strut, then safety release is achieved, but reassembly requires precise alignment causing inconvenience
Solution Approach 1:
The magnetic coupling device enables automatic alignment during reassembly through magnetic attraction between the first and second members. When the user brings the separated parts close together, the magnetic force automatically guides them into the correct positioned, eliminating the need for precise manual alignment required by conventional devices.
Solution Approach 2:
The patent replaces the complex mechanical alignment mechanisms of conventional coupling devices with a magnetic field-based system. The magnetic attraction force provides both the coupling strength for safety release and the automatic alignment function, substituting mechanical precision requirements with magnetic field guidance.
2Strength
If conventional coupling devices are used, then structural connection is achieved, but automatic safety separation is not ensured when clothing is caught
Solution Approach 1:
The magnetic coupling device uses adjustable magnetic strength as a key parameter to balance connection strength and automatic safety separation. By controlling the magnetic field strength, the device maintains strong connection during normal use but allows automatic separation when sufficient force (such as clothing being caught) overcomes the magnetic attraction, providing inherent safety without additional mechanical release mechanisms.
