Magnetic Hinge Mechanism for Portable Device Support Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable electronic devices with hidden support brackets require complex interlocking mechanisms that occupy space and are cumbersome, lacking an efficient design for opening and closing the support bracket.
Innovation Solution
A portable electronic device design featuring a main body, hinge unit, and driving unit with magnetic connecting elements that allow the support unit to rotate from a closed to a support state through a repulsive force generated by moving magnetic elements, enabling one side of the device body to detach from the support unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex interlocking mechanism is used to connect the support bracket, then the support bracket can be securely fixed, but the device occupies more space and becomes more cumbersome
Solution Approach 1:
The patent replaces the traditional mechanical interlocking mechanism with a magnetic field-based connection system. Magnetic attracting elements and magnetic repelling elements generate magnetic forces to achieve connection and detachment of the support bracket, eliminating complex mechanical interlocking structures while maintaining secure fixation.
Solution Approach 2:
The patent changes the physical state or properties of the connecting elements by using magnetic fields instead of mechanical structures. The magnetic attracting elements and magnetic repelling elements utilize magnetic field parameters to control the connection and detachment states, simplifying the overall mechanism.
2Reliability
If a traditional mechanical connection mechanism is used for the support bracket, then the connection is reliable, but more space is occupied inside the device
Solution Approach 1:
The patent substitutes mechanical connection components with magnetic field-based connecting elements. The magnetic attracting elements and magnetic repelling elements create connection forces without requiring bulky mechanical structures, significantly reducing the space occupied inside the device while maintaining connection reliability.
3Reliability
If a complex interlocking mechanism is used to open and close the support bracket, then the bracket can be securely held, but the operation becomes cumbersome
Solution Approach 1:
The patent replaces complex mechanical interlocking operations with simple magnetic field interactions. Users can open or close the support bracket by triggering the magnetic repelling elements, which generate repulsive forces to detach the bracket, or by allowing magnetic attracting elements to re-engage, making the operation intuitive and effortless.
Solution Approach 2:
The magnetic connection system provides self-service functionality where the magnetic attracting elements automatically re-engage the support bracket when the repulsive force is removed, eliminating the need for complex manual manipulation of interlocking mechanisms.

Function Achieved in This Case
This design simplifies the mechanism for opening and closing the support unit, reducing space occupation and enhancing user convenience by using magnetic repulsion to rotate the support unit from a closed to a support state, allowing one side of the device body to detach.
Implementation Method 1
When the driving unit moves from an initial position to a driving position, attraction between magnetic poles is changed to repulsion, the second connecting element detaches from the fourth connecting element

AI summary
A portable electronic device has a device body, a hinge unit, a driving unit and a support unit. The device body has a first connecting element. The hinge unit disposes at an end of the device body. The driving unit disposes in the device body and has a second connecting element. The support unit rotates relative to the device body for a closed state and a support state. The support unit has a third connecting element and a fourth connecting element. When the support unit in the closed state, the third connecting element connects with the first connecting element; the fourth connecting element connects with the second connecting element. When the driving unit moves to a driving position, the fourth connecting element detaches from the second connecting element, and the support unit rotates to the support state due to rotation of the hinge unit.
