Non-Planar Magnetic Alignment Structure for Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional docking stations for portable electronic devices often suffer from inaccurate alignment due to planar magnetic attractive surfaces, leading to lateral shifts and poor alignment accuracy.
Innovation Solution
The alignment structure employs non-planar magnetic surfaces on the first and second casings, with the first surface and second surface having distinct ends that maximize magnetic attraction, guiding the second casing to align accurately with the first casing through unequal magnetic forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If planar magnetic attractive surfaces are used, then the magnetic attraction force is uniform across the surface, but the alignment accuracy deteriorates due to lateral shifts
Solution Approach 1:
The patent applies asymmetry by changing the magnetic attractive surface from a planar (symmetric) shape to a non-planar (asymmetric) shape. The non-planar surface includes a slope that creates unequal magnetic attraction forces across different regions, generating a directional alignment force that eliminates lateral shifts and improves docking accuracy between the portable electronic device and docking station.
Solution Approach 2:
The patent applies local quality by creating different surface characteristics at different locations of the magnetic component. The non-planar surface has a slope region with different geometric properties compared to other regions, causing the magnetic attraction force to vary spatially. This localized variation in surface quality creates a gradient in magnetic force that guides precise alignment while maintaining overall attachment stability.
2Stability of the object's composition
If a hook is used to fix the portable electronic device, then the device can be secured, but the appearance deteriorates and alignment convenience is reduced
Solution Approach 1:
The patent replaces the mechanical hook fixation system with a magnetic field-based fixation system. Instead of using a physical hook that requires manual alignment and degrades appearance, the invention uses magnetic attraction forces between corresponding magnets on the device and docking station to achieve both secure fixation and alignment guidance, eliminating the need for mechanical hooks entirely.
Solution Approach 2:
The patent changes the parameter of magnetic surface geometry from planar to non-planar. This parameter change transforms the uniform magnetic attraction into a directional force field with gradient characteristics, enabling the magnetic system to perform both fixation and alignment functions simultaneously, thereby replacing the need for separate mechanical hooks.

AI summary
An alignment structure including a first casing, a first magnetic component, a second casing and a second magnetic component is provided. The first magnetic component is disposed at the first casing and has a first surface, and the first surface is a non-planar surface. The second magnetic component is disposed at the second casing and has a second surface, and the second surface is a non-planar surface. When the second casing leans against the first casing, the first surface and the second surface are facing each other, and a magnetic attraction between the first magnetic component and the second magnetic component guides the second magnetic component to be aligned to the first magnetic component, and stops the second casing from being separated from the first casing.
