Solution Overview
Problem
Smart ring wearable devices face challenges such as needing to be removed for charging, poor fit, and limited functionality, particularly due to the difficulty in reliably powering components within the compact form factor.
Innovation Solution
A smart ring charging system with a charging source integrated into objects that users can hold, enabling wireless energy transfer via inductive coupling between a transmitting coil in the object and a receiving coil in the smart ring, allowing for charging without removing the ring, along with indicators to display the charging rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the smart ring uses a compact form factor with integrated power source, then the device portability and wearability are improved, but the charging reliability and ease of operation deteriorate because the ring must be removed for charging
Solution Approach 1:
The patent replaces the mechanical contact-based charging system with a wireless inductive charging system. The transmitting coil in the charging source generates a magnetic field that induces current in the receiving coil of the smart ring, eliminating the need for physical connection and removal of the ring for charging.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the charging source and the smart ring power source. The transmitting coil converts electrical energy to magnetic energy, which then induces electrical current in the receiving coil, serving as a non-contact energy transfer mediator.
2Adaptability or versatility
If the smart ring maintains continuous wear on the finger, then the user interaction and functionality are improved, but the charging capability worsens because traditional charging requires ring removal
Solution Approach 1:
The patent replaces the mechanical contact-based charging system with a wireless inductive charging system. The transmitting coil in the charging source generates a magnetic field that induces current in the receiving coil of the smart ring, eliminating the need for physical connection and removal of the ring for charging.
Solution Approach 2:
The patent enables continuous charging capability while the smart ring remains worn on the user's finger. The wireless inductive charging allows the power source to be recharged without interrupting the continuous wear and usage of the device, maintaining uninterrupted functionality.
3Ease of operation
If the smart ring uses wireless inductive charging, then the charging convenience is improved, but the device complexity increases due to additional coils and control circuits
Solution Approach 1:
The patent merges the transmitting coil and control circuitry into an integrated charging source unit. This consolidation combines multiple components into a single system, managing the complexity by integrating rather than separating the wireless charging elements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and continuous charging of smart rings, enhancing user interaction and functionality by maintaining the ring on the finger while powering its components efficiently.
Implementation Method 1
the smart ring may include 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
Data 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.
