Solution Overview
Problem
Existing magnetic smartphone mounts with inductive charging features are limited by the space occupied by the charging coil, making it difficult to achieve optimal mounting and rotation of devices, which restricts orientation changes and is cumbersome to use.
Innovation Solution
A rotatable inductive charger dock with a stator cap, rotor frame, and opposed magnet support arms that allow for magnetic coupling and easy rotation of smartphones between landscape and portrait orientations while maintaining a wireless charging connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a magnetic mount with inductive charging is used, then wireless charging capability is provided, but the charging coil occupies space that restricts device mounting and rotation
Solution Approach 1:
The magnetic mount is divided into separate functional components: a magnetic mounting structure for securing the device and a separate inductive charging coil assembly. This segmentation allows the charging coil to be positioned in a location that does not interfere with the magnetic mounting area, enabling both wireless charging and flexible device rotation to be achieved simultaneously
Solution Approach 2:
The charging coil is positioned in a different spatial dimension or plane relative to the magnetic mounting surface. By relocating the coil to an adjacent area or different layer, the patent eliminates the spatial conflict between the coil and the magnetic mount, allowing devices to be mounted and rotated freely on the magnetic surface while charging occurs independently in another dimension
2Productivity
If the charging coil is positioned centrally for optimal charging, then charging efficiency is improved, but device rotation between orientations becomes difficult
Solution Approach 1:
The charging system is segmented into a stationary charging coil assembly and a movable device mounting area. The coil remains fixed in an optimal position for charging efficiency, while the device can be placed and rotated in the magnetic mounting zone that is spatially separated from the coil, allowing orientation changes without compromising charging performance
Solution Approach 2:
A magnetic coupling mechanism acts as an intermediary between the device and the charging coil. The magnetic mount secures the device in place and allows rotation, while maintaining the device's proximity to the charging coil through magnetic attraction, thus enabling orientation changes while preserving charging efficiency
