Magnetic Stand Mechanism for Tablet Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tablet computers require manual opening and closing of the stand, which is inconvenient for switching between tablet and notebook computer operation modes.
Innovation Solution
A portable electronic device with a magnetic assembly comprising a first and second magnetic dipole, allowing the stand to be automatically opened or closed relative to the body through magnetic attraction and repulsion forces, eliminating the need for manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stand and pivot mechanism are used to enable notebook computer operation mode, then applicability is improved, but manual opening and closing operation is required which reduces convenience
Solution Approach 1:
The patent replaces the traditional mechanical spring-based automatic stand mechanism with a magnetic field-based system. Magnetic dipoles embedded in the body interact with magnetic assemblies in the stand to provide automatic opening and closing forces, eliminating the need for manual operation while maintaining the ability to switch between tablet and notebook computer modes
Solution Approach 2:
The magnetic assembly automatically opens or closes the stand based on the relative positions of magnetic dipoles, without requiring user intervention. The system self-regulates the stand position through magnetic attraction and repulsion forces, improving ease of operation while preserving adaptability
2Productivity
If manual stand operation is used, then device complexity is reduced, but opening/closing efficiency is lowered
Solution Approach 1:
The patent changes the physical state and interaction parameters by introducing magnetic dipoles and magnetic assemblies. These components create variable magnetic forces that automatically adjust stand position, significantly improving opening/closing efficiency. The added complexity is localized to the magnetic components while the overall device structure remains relatively simple
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
Enhances user convenience by allowing effortless switching between operation modes without manual intervention, improving the efficiency and usability of the device.
Implementation Method 1
magnetic poles with opposite polarities of the first magnetic dipole and the second magnetic dipole correspond to and attract each other, such that the stand is closed to the body due to the attraction
Implementation Method 2
magnetic poles with the same polarity of the first magnetic dipole and the second magnetic dipole correspond to and repel each other, and the stand is spread relative to the body due to the repulsion

AI summary
A portable electronic device including a body, a stand, and first and second magnetic assemblies is provided. The stand is pivoted to the body to rotate and being opened or closed relative to the body. The first magnetic assembly having a first magnetic dipole is movably disposed in the body. The second magnetic assembly having a second magnetic dipole is disposed on the stand. When the stand is closed to the body, the first and second magnetic dipoles correspond to each other, and produce a first and second corresponding states. In the first corresponding state, magnetic poles with opposite polarities of the first and second magnetic dipoles correspond to and attract each other. In the second corresponding state, magnetic poles with the same polarity of the first and second magnetic dipoles correspond to and repel each other, and the stand is spread relative to the body due to the repulsion.
