Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If external chargers are used to supply power to wearable devices, then sufficient battery power can be maintained, but users need to carry more devices which reduces convenience
Solution Approach 1:
The microphone interface is designed to serve dual purposes: traditional audio signal transmission and power supply. By enabling the same interface to perform multiple functions, the patent eliminates the need for separate charging devices, allowing users to charge wearable devices using the microphone interface of connected devices like smartphones, thereby improving convenience without compromising battery power maintenance
Solution Approach 2:
The patent combines the power supply function with the existing microphone interface infrastructure. Instead of using separate charging ports or external chargers, the power transmission is merged into the audio connection pathway, allowing a single connection to simultaneously handle both audio and power transmission needs
2Ease of operation
If power is supplied through the microphone interface, then convenience is improved and cost is reduced, but it may affect microphone functionality
Solution Approach 1:
The power management module implements segmented power distribution by providing different voltage levels to different components based on operational mode. During voice communication, the system supplies appropriate power to the microphone through the microphone interface while simultaneously providing power to the wearable device, using voltage regulation to ensure each component receives the correct power level without interference
Solution Approach 2:
The system dynamically adjusts voltage output based on operational requirements. The power management module detects the operational state and dynamically changes the voltage provided through the microphone interface - providing first voltage during voice communication to maintain microphone functionality, and second voltage (higher than first voltage) during other operations to maximize power transfer to the wearable device

AI summary
A power supply manageable wearable device and a power supply management method thereof are disclosed. The wearable device includes: a power management module connected to the microphone interface, a control module and a function module that are connected to the power management module respectively; wherein the control module monitors whether a user instruction includes a voice communication instruction; if the user instruction includes the voice communication instruction, the power management module is enabled to supply power to a microphone and output a first voltage to supply power to the control module; or otherwise, the power management module is enabled to cut off power supply to the microphone and output a second voltage to supply power to the control module and the function module, or output the first voltage to supply power to the control module and output the second voltage to supply power to the function module, the first voltage being less than the second voltage. According to the present application, on the premise of not affecting use of the microphone in the wearable device, power may be supplied to the wearable device. The wearable device according to the present application has the advantages of convenient use and low cost.
