Magnetic Support Mechanism for Portable Electronic Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with rotatable bodies, such as laptops, experience instability and shaking when the display body is unsupported, making operation inconvenient due to tilting or shaking when touched.
Innovation Solution
A supporting mechanism within the device, comprising a support shaft, magnetic element, and positioning stand, is used to stabilize the display body by magnetically attracting and locking it in place, preventing tilting and enhancing operational stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second body is made unsupported to enable 360-degree rotation, then the adaptability of the device is improved, but the stability of the second body deteriorates
Solution Approach 1:
The support mechanism transitions from a static fixed structure to a dynamic adjustable structure that can move between stored and supporting positions, allowing the second body to be unstable during rotation but stable when supported at desired angles
Solution Approach 2:
The magnetic element acts as an intermediary between the support mechanism and the second body, providing magnetic attraction to hold the second body in position while allowing easy attachment and detachment without mechanical complexity
2Stability of the object's composition
If a support mechanism is added to stabilize the second body, then the stability is improved, but the device complexity increases
Solution Approach 1:
The support function is extracted as a separate movable mechanism independent of the main rotating hinge structure, allowing it to be stored when not needed and deployed only when support is required
Solution Approach 2:
The support mechanism uses the weight of the second body itself and magnetic attraction to achieve automatic positioning and locking, eliminating the need for motors, sensors, or complex control systems
3Ease of operation
If the magnetic element is positioned close to the opening for quick deployment, then the ease of operation is improved, but the reliability of magnetic attraction decreases
Solution Approach 1:
The support shaft moves along a guide rail in a vertical direction perpendicular to the opening plane, allowing the magnetic element to approach the second body from a different spatial dimension while maintaining strong magnetic attraction
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 supporting mechanism effectively prevents the display body from shaking or tilting when touched, improving operational convenience and stability by securely supporting it through magnetic attraction and multi-stage positioning adjustments.
Implementation Method 1
the magnetic element is magnetically attracted to the magnetic part... the magnetic element and the support shaft are driven by the second body to move out from the first body via the opening... the magnetic element is pivoted to the second end part

AI summary
A portable electronic device (100, 100A, 100B) including a first body (110), a second body (120) and a supporting mechanism (130, 130a, 130b) is provided. The first body (110) has a bottom surface (112) and an opening (113) located at the bottom surface (112). The second body (120) is pivoted to the first body (110) and has a rear surface (122) and a magnetic part (123) located at the rear surface (122). The supporting mechanism (130, 130a, 130b) is disposed in the first body (110) corresponding to the opening (113). The rear surface (122) of the second body (120) is rotated toward the bottom surface (112) of the first body (110) to allow the supporting mechanism (130, 130a, 130b) to be magnetically attracted to the magnetic part (123). Afterwards, the rear surface (122) of the second body (120) is rotated away from the bottom surface (112) of the first body (110), and the supporting mechanism (130, 130a, 130b) is driven by the second body (120) to move out of the first body (110) via the opening (113). When the supporting mechanism (130, 130a, 130b) is locked, a support shaft (131) supports the second body (120).
