Solution Overview
Problem
Wearable ring devices often fail to charge efficiently due to misalignment of inductive coils between the device and the charger, leading to reduced or ineffective charging.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable ring device is placed on the charging device in multiple radial orientations, then the user convenience is improved, but the alignment between inductive coils deteriorates leading to charging failure
Solution Approach 1:
The charging device incorporates a step motor that dynamically adjusts the radial orientation of the wearable ring device during charging. The motor rotates the device to the correct orientation based on detection signals, transforming a static alignment problem into a dynamic adjustment process that maintains both user convenience and coil alignment.
2Manufacturing precision
If a step motor is added to rotate the wearable ring device into correct orientation, then the coil alignment is improved, but the device complexity increases
Solution Approach 1:
The charging device uses a detection component to automatically detect the radial orientation of the wearable ring device and triggers the step motor to rotate it into the correct position. This self-service mechanism eliminates the need for manual alignment by the user while maintaining relatively simple system architecture through automated feedback control.
3Productivity
If the inductive coils are properly aligned through mechanical rotation, then the charging efficiency is improved, but the loss of time for orientation adjustment occurs
Solution Approach 1:
The detection component continuously monitors the radial orientation of the wearable ring device and triggers the step motor rotation in advance before charging inefficiency occurs. This preliminary detection and adjustment mechanism ensures that the coils are aligned before the charging process begins, minimizing orientation adjustment time and maximizing charging efficiency.

AI summary
Methods, systems, and devices for a charging device are described. Some charging devices may include a base, a charging post extending from the base, and a charging component disposed within the charging post. The charging component may be configured to wirelessly charge a wearable ring device through a surface of the charging post. Additionally, the charging device may include a rotational alignment component extending from the base, the rotational alignment component including a curved surface configured to contact an outer curved surface of the wearable ring device when the wearable ring device is positioned around the charging post. The charging device may further include a motor to rotate the wearable ring device via rotation of the rotational alignment component to align the charging component of the charging device with an additional charging component of the wearable ring device for charging.
