Watch-Type Mobile Terminal Power Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watch-type mobile terminals face challenges in minimizing power consumption due to their small battery capacity and the need to enhance user convenience while maintaining functionality.
Innovation Solution
The implementation of a control unit that operates in both normal and low-power modes, allowing for a standby screen with high luminance in normal mode and ambient screens with lower luminance in low-power mode, which reduces power consumption by minimizing the display of information and using lower power settings for the touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display operates in normal mode with high luminance, then the user experience and visibility are improved, but the power consumption increases
Solution Approach 1:
The display system dynamically switches between normal mode and low-power mode based on operational requirements. The control unit adjusts the display characteristics in real-time, transitioning from high luminance normal mode to lower luminance low-power mode when full display performance is not needed, thereby optimizing the balance between visibility and power consumption
Solution Approach 2:
The system changes the operational parameters of the display by switching between two distinct modes: normal mode with higher luminance for better visibility, and low-power mode with reduced luminance for energy conservation. This parameter switching allows the device to adapt its power consumption characteristics based on the current usage scenario
2Duration of action of moving object
If the battery capacity is increased to maintain functionality, then the operational duration is extended, but the device size increases
Solution Approach 1:
The low-power mode enables continuous operation of essential functions with reduced power consumption. By maintaining core functionalities in a lower power state, the system extends the effective operational duration of the battery without requiring additional capacity, thereby avoiding increased device size
Solution Approach 2:
The system periodically transitions between normal mode and low-power mode based on usage patterns. During periods when full performance is not required, the device operates in low-power mode, effectively extending the average operational duration without increasing battery capacity or device volume
