Solution Overview
Problem
Smart ring wearable devices face challenges such as the need for removal for charging, poor fit, limited user interactivity, and restricted functionality, particularly due to the limited space for a power source in their compact form factor.
Innovation Solution
A smart ring charging system is configured with a charging source integrated into objects that users can hold, allowing wireless energy transfer via inductive coupling between the charging source and the smart ring's power source, with indicators providing feedback on the charging rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a smart ring uses a compact form factor with limited space for power source, then the device portability and wearability are improved, but the charging convenience deteriorates as the device needs to be removed for charging
Solution Approach 1:
The patent replaces the mechanical connection system (physical charging port and cable insertion) with a wireless inductive charging system. The smart ring includes a receiving coil that wirelessly receives power from a charging source through electromagnetic induction, eliminating the need for mechanical connection and allowing charging while the ring remains on the user's finger.
Solution Approach 2:
The patent introduces an intermediary electromagnetic field between the charging source and the smart ring's power source. The receiving coil in the smart ring and the transmitting coil in the charging source create an electromagnetic coupling that transfers energy wirelessly, serving as an intermediary mechanism that enables power transfer without direct physical contact.
2Ease of operation
If a smart ring uses wireless inductive charging, then the charging convenience is improved, but the device complexity increases due to additional components like receiving coils
Solution Approach 1:
The patent makes the charging source universal by integrating it into common objects in the environment (such as desks, tables, or other surfaces). This multi-functional approach allows the same charging infrastructure to serve multiple purposes and locations, reducing the need for specialized charging equipment and simplifying the overall system deployment.
3Adaptability or versatility
If a smart ring provides real-time charging rate feedback through indicators, then the user interactivity is improved, but the device complexity increases due to additional I/O components
Solution Approach 1:
The patent implements a feedback mechanism where the controller monitors the charging rate and communicates this information to the user through I/O components. The user interface provides real-time feedback about the charging status and rate, allowing users to understand and interact with the charging process, thereby improving user awareness and control.

Function Achieved in This Case
This solution enables convenient charging of smart rings without removing them from the finger, improving user experience by providing a compact, efficient, and user-friendly charging method.
Implementation Method 1
a receiving induction coil configured to generate a voltage in response to a change in magnetic flux through the coil, the magnetic flux associated with one or more transmitting coils electrically connected to the charging source

AI summary
A smart ring charging system comprises a charging source integrated into an object, the object configured to be held by a user wearing a smart ring. The smart ring may include a ring-shaped housing and a power source disposed within or at the ring-shaped housing and configured to receive energy from the charging source while the user is wearing the smart ring and holding the object. A controller may be disposed within or at the ring-shaped housing, or at the object with the charger and configured to estimate a charging rate at which the power source receives the energy from the charging source. The system may further include one or more indicators configured to indicate the charging rate.
