Magnetic Locking Switch for Mobile Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional selfie sticks with elastic clamps are inconvenient for users as they require time-consuming and laborious operations to mount and dismount mobile devices for shooting and browsing, and frequent retraction and extension to switch between shooting and browsing modes.
Innovation Solution
An auxiliary shooting device with a telescopic rod, connecting base, locking switch assembly, magnetic positioning assembly, and adapter base that allows quick mounting and dismounting of mobile devices using elastic retaining pieces and magnetic connections, eliminating the need for manual screwing and nuts, and enabling seamless transitions between shooting and browsing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional elastic clamps are used to mount mobile devices on selfie sticks, then the device can be securely held, but the operation of mounting and dismounting becomes time-consuming and inconvenient
Solution Approach 1:
The elastic clamp is divided into a clamping body and separate clamping arms that can independently move. The clamping arms are equipped with magnetic pieces that interact with corresponding magnetic pieces on the clamping body, enabling segmented magnetic attraction for automated clamping action without manual adjustment.
Solution Approach 2:
The manual mechanical adjustment process is replaced by magnetic attraction forces. When the clamping arms approach the clamping body, the magnetic pieces attract each other automatically, causing the arms to move and clamp the device without requiring manual screwing or complex mechanical adjustments.
2Adaptability or versatility
If the telescopic rod is frequently extended and retracted to switch between shooting and browsing modes, then the mobile device can be used for both purposes, but the operation becomes laborious and time-consuming
Solution Approach 1:
The selfie stick system is segmented into a detachable connection structure where the clamping portion can be separated from the telescopic rod. This allows the mobile device to remain clamped while the telescopic rod is retracted for browsing, or the clamping portion is detached entirely, eliminating the need to repeatedly extend and retract the rod for mode switching.
3Reliability
If manual screwing and nuts are used for assembly, then the connection is secure, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
The manual screwing and nut assembly is completely replaced by magnetic attraction mechanisms. The magnetic pieces on the clamping arms and clamping body automatically attract each other to secure the connection, eliminating the need for tools and manual fastening operations while maintaining secure attachment.
Solution Approach 2:
The magnetic pieces are positioned such that when the clamping arms approach the clamping body, the magnetic attraction automatically pulls the arms into the clamped position without requiring manual intervention. The system serves itself by using magnetic forces to complete the assembly action.
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 device provides a labor-saving and convenient way to use mobile devices for photography, allowing quick assembly and disassembly without the need for repeated retraction and extension of the telescopic rod, enhancing user experience by simplifying the switching between shooting and browsing.
Implementation Method 1
A magnetic pole of the at least one first magnet is opposite to a magnetic pole of the at least one second magnet and a magnetic pole of the at least one third magnet, so the at least one first magnet is alternatively magnetically connected to the at least one second magnet and the at least one third magnet.

AI summary
An auxiliary shooting device for a mobile device includes a telescopic rod, a connecting base, a connecting bracket and a locking switch assembly. The telescopic rod includes a handheld portion. The connecting base is connected to one end of the telescopic rod away from the handheld portion. The connecting bracket includes locking grooves and a clamping portion for clamping the mobile device. The locking switch assembly includes elastic retaining pieces and locking pieces. The locking pieces are rotatably connected to the connecting base. Each of the locking pieces includes a pressing portion and a hook portion. When each pressing portion is pressed, each of the elastic retaining pieces is compressed, and each hook portion moves away from the connecting base. The locking pieces are matched with the locking grooves of the connecting bracket. The elastic retaining pieces respectively abut against the locking pieces and the connecting base.
