Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If magnetic connection is used in existing quick-release apparatus, then the structure is simple, but the magnetic stability is poor and the apparatus is easy to fall off while being shaken
Solution Approach 1:
The patent replaces the magnetic connection system with a mechanical gear-based locking system. The gear stand with positioning gear ring engages with the limiting gear ring on the gear turntable, creating a purely mechanical connection that eliminates reliance on magnetic force while maintaining structural simplicity through the gear mechanism.
Solution Approach 2:
The connection system is divided into distinct functional components: the gear turntable for mounting, the gear stand with positioning mechanism for locking, and the anti-rotation plate for preventing detachment. This segmentation allows each component to perform its specific function optimally, with the positioning gear ring providing rotational locking and the anti-rotation plate providing lateral stabilization.
2Reliability
If large magnetic force is used to improve stability, then the quick-release apparatus is more stable, but the electromagnetic signal of the terminal device is interfered and iron-containing parts may be magnetized
Solution Approach 1:
The patent completely replaces the magnetic field-based connection with a mechanical gear engagement system. The positioning gear ring on the gear stand meshes with the limiting gear ring on the gear turntable, providing stable connection through mechanical interlocking rather than magnetic attraction, thereby eliminating electromagnetic interference with terminal devices.
Solution Approach 2:
The gear mechanism acts as an intermediary between the mounting bracket and the terminal device. Instead of direct magnetic contact, the gear stand with its positioning mechanism mediates the connection through controlled engagement of gear rings, providing stable attachment without magnetic field exposure to the terminal device.
3Device complexity
If snap-fit connection is used in existing quick-release apparatus, then the structure is simple, but the protection is poor and the quick-release apparatus is easy to fall off causing damage
Solution Approach 1:
The protection system is segmented into multiple functional elements: the gear stand providing structural support, the positioning gear ring for rotational locking, the limiting gear ring for engagement, and the anti-rotation plate for lateral prevention. This segmentation distributes the protective function across multiple components rather than relying on a single snap-fit feature.
Solution Approach 2:
The anti-rotation plate extends to limit the rotation range of the terminal device beforehand, preventing excessive movement that could cause damage. The positioning gear ring and limiting gear ring are pre-configured to engage at specific positions, providing prior constraint against unintended detachment or rotation before any damaging event can occur.
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
The apparatus provides a stable and protected connection for electronic devices, preventing detachment and signal interference, while allowing easy mounting and adjustment of device angles, improving user convenience and safety.
Implementation Method 1
a limiting spring, disposed at a bottom of the gear stand, and configured to control a clearance between the positioning gear ring and the limiting gear ring
Implementation Method 2
at least four spring steel beads are disposed inside the connection base, one end of the spring steel bead abuts against an inner wall of the arc-shaped groove

AI summary
The present disclosure discloses a fixed quick-release apparatus. It includes: a gear turntable, configured to connect a cycling bracket, where a limiting gear ring is disposed on a top circle of the gear turntable; a housing, configured to mount the gear turntable; and a gear stand, mounted inside the housing, where a positioning gear ring that is opposite to the limiting gear ring is disposed on a bottom circle of the gear stand, an anti-rotation plate is disposed at a top of the gear stand, and a limiting spring, disposed at a bottom of the gear stand. Because the gear stand is driven to move by pressing the button, the positioning gear ring is engaged with the limiting gear ring, to limit rotation of the locking turntable and the unlocking of the anti-rotation plate on the terminal device. Because the spring steel beads abut against the arc-shaped groove, the terminal device can be adjusted and positioned by rotating 360°.
