Acute-Angle Rotating Stand That Avoids Magnetic Charging Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic equipment accessories with support functionality, such as mobile phone cases, face instability when stands are positioned near the edges due to interference with magnetic attraction structures and wireless charging coils, necessitating a design that avoids these areas.
Innovation Solution
A rotating device with an acute angle between connecting members allows the stand to be positioned between the magnetic charging structure and the bottom edge, ensuring stable support without interference, featuring a shaft and connecting members that are rotatable and offset to minimize protrusion and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stand is positioned near the middle area of the electronic equipment accessory, then the support stability is improved, but the magnetic attraction structure and wireless charging coils are interfered with
Solution Approach 1:
The patent introduces a rotating device with a shaft that extends in a thickness direction (third dimension) perpendicular to the front and back surfaces of the accessory. This allows the stand to be positioned away from the middle area in the planar dimensions while maintaining support stability through the vertical dimension. The shaft's rotation axis is offset from the center, enabling the stand to occupy space in the thickness direction rather than interfering with middle-area components.
Solution Approach 2:
The rotating device features asymmetric positioning where the shaft's rotation axis is deliberately offset from the center of the accessory. This asymmetric design allows the stand to be positioned in a location that avoids interference with magnetic attraction structures and wireless charging coils typically located in the middle area, while still providing effective support when rotated to the appropriate position.
2Object-affected harmful factors
If the stand is positioned near the edges of the mobile phones, then the magnetic attraction structure and wireless charging coils are not interfered with, but the support stability deteriorates
Solution Approach 1:
By utilizing the thickness direction (third dimension) with the shaft extending perpendicular to the front and back surfaces, the patent enables the stand to achieve support stability without being constrained to edge positions in the planar view. The stand can be positioned away from edges while maintaining stability through its vertical extension and rotation capability.
Solution Approach 2:
The rotating device provides dynamic positioning capability, allowing the stand to be rotated to different positions. This dynamic feature enables the stand to occupy optimal support positions when needed while avoiding interference with middle-area components, transforming a static positioning problem into a dynamic solution.
3Reliability
If the rotating device is positioned in the middle area, then the support function is improved, but the magnetic charging structure is shielded
Solution Approach 1:
The shaft extending in the thickness direction allows the rotating device to be positioned such that it occupies vertical space rather than horizontal space in the middle area. This dimensional shift enables the support function to be achieved without the device body shielding the magnetic charging structure located in the middle plane of the accessory.

AI summary
A rotating device and an electronic equipment accessory are provided. The rotating device includes a first connecting member and a second connecting member rotatable about a rotation axis relative to the first connecting member. An angle formed between the rotation axis and a length direction of the rotating device is acute such that the second connecting member can move upwards when rotating with respect to the first connecting member. Therefore, when the rotating device is applied to an electronic equipment accessory which is mounted on electronic equipment, the rotating device acting as a stand can be arranged between a magnetic charging structure of electronic equipment and a bottom edge of the electronic equipment, such that the rotating device will not shield the magnetic charging structure. The rotating device can act as a stand with a good support effect due to existing of the acute angle.
