Solution Overview
Problem
Smart ring-shaped electronic devices face challenges in being used while charged, due to limited size and small battery capacity, making it difficult to provide functions effectively during charging.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the smart ring-shaped electronic device is made small to be worn on the body, then it can be worn comfortably, but the battery capacity becomes limited and cannot provide sufficient power
Solution Approach 1:
The power system is segmented into two parts: a small battery inside the wearable ring device and a larger external battery in the charging device. The ring device maintains its small size for comfort while the external charging device provides additional power capacity through the coupling mechanism.
Solution Approach 2:
The power capacity is extended from the one-dimensional constraint of the ring device to a two-dimensional system by adding the external charging device. The coupling part enables power transfer between devices, effectively increasing the available battery capacity without increasing the wearable device's size.
2Use of energy by moving object
If the smart ring-shaped electronic device is charged by being disposed on an external holding device, then power can be transmitted, but the user has difficulty using the ring device while it is being charged
Solution Approach 1:
The coupling mechanism is designed to be detachable and reconfigurable. The coupling part can be formed on different surfaces (first, second, or third coupling surfaces) allowing the devices to be coupled in various orientations. This dynamic configuration enables the user to maintain usability of the ring device while charging, as the devices can be positioned to allow interaction with the ring device's interface.
3Reliability
If the connection terminal is formed on the housing to enable electrical connection, then power transmission is achieved, but the device structure becomes more complex
Solution Approach 1:
The coupling part serves multiple functions: it provides mechanical attachment between the devices, establishes electrical connection through the connection terminal, and enables power transmission. By integrating these functions into a single coupling structure, the design avoids adding separate components for each function, thereby reducing overall structural complexity while ensuring reliable electrical connection.
