Rotating Buckle Phone Mount for One-Handed Secure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone accessories, such as arm bags and holders, are inconvenient for use during activities like sports or navigation due to the need to remove the phone for calls, unstable installation, and difficulty in one-handed access and removal.
Innovation Solution
A digital product fixing device comprising a mobile phone patch, a shell with a rotating wheel and buckle mechanism, and a buckle spring, allowing for easy one-handed installation and removal of the phone by adjusting the rotating wheel's angle to buckle or unlock the mobile phone patch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the phone is placed in a transparent bag with no opening, then the phone is protected and secured, but the sound output is very small and phone calls cannot be made conveniently
Solution Approach 1:
The bag is divided into separate compartments: a transparent storage bag for the phone and a separate control area with buttons and speakers. This segmentation allows the phone to remain secured in the bag while still enabling audio output and control functions through the separate compartments, resolving the contradiction between security and accessibility.
2Reliability
If the phone holder uses a fixed clamping mechanism, then the phone is securely held, but it requires two hands to install and remove the phone
Solution Approach 1:
The clamping mechanism uses a rotating wheel that converts rotational motion into linear clamping motion through a cam mechanism. This dynamic mechanism allows one-handed operation where rotating the wheel simultaneously adjusts the clamping force and secures the phone, eliminating the need for two hands while maintaining secure holding.
Solution Approach 2:
The spring-loaded buckle mechanism automatically adjusts and maintains clamping pressure on the phone once the rotating wheel is turned. The spring provides continuous force to keep the phone secured without requiring constant manual adjustment, making the system self-regulating and easy to operate with one hand.
3Device complexity
If the buckle mechanism uses a simple spring design, then the structure is simple, but the buckle is unstable and may detach accidentally
Solution Approach 1:
The cam mechanism converts the rotational motion of the wheel into controlled linear motion of the buckle, providing a mechanical advantage that increases clamping force. This dynamic mechanical transformation allows a relatively simple spring design to generate sufficient and stable clamping pressure, preventing accidental detachment while maintaining structural simplicity.
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
Enables easy one-handed installation and disassembly of the mobile phone, stabilizing it during use and preventing accidental detachment, thus addressing the inconvenience and instability issues of prior art products.
Implementation Method 1
a cam is protruded and provided on the bottom surface of the mounting cavity of the shell; one end of the mobile phone patch is inserted into the buckle cavity of the rotating wheel, the cam makes the buckle spring drive the buckle spring inward to buckle the mobile phone patch when the rotating wheel turns into a first angle range, and pushes the buckle outward so as to unlock the clamping
Implementation Method 2
the buckle is retractably provided along the radial of the rotating wheel through the buckle spring, the cam makes the buckle spring drive the buckle spring inward to buckle the mobile phone patch
Implementation Method 3
the digital product fixing device further includes a rotating return spring, an end of the rotating return spring is connected with the shell, and another end of the rotating return spring is connected with the rotating wheel
