Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals with wireless LAN connection functions consume excessive power, leading to shortened battery life, as existing solutions only address power reduction before communication starts, neglecting ongoing power consumption during internet connection.
Innovation Solution
A mobile communication terminal with a communication method determining unit that assesses available wireless LAN connectivity and a communication method selecting unit that switches to mobile communication when the battery level falls below a threshold, allowing user selection and providing warnings and power-off notifications to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless LAN connection function is kept in operation all time, then data communication availability is improved, but power consumption increases and drivable time becomes short
Solution Approach 1:
The patent implements dynamic switching between wireless LAN and mobile communication modes based on real-time battery level monitoring. The system transitions from a static always-on configuration to a dynamic adaptive mode, automatically selecting the appropriate communication method based on current power conditions to resolve the contradiction between availability and power consumption
Solution Approach 2:
The system changes the operational parameter of communication method selection based on battery level thresholds. When battery level exceeds a threshold, wireless LAN is activated for high-speed communication; when below the threshold, the system switches to mobile communication mode, thereby adjusting system behavior according to power availability to balance performance and energy consumption
2Speed
If wireless LAN connection operation is performed, then data communication speed is improved, but battery remaining amount decreases faster
Solution Approach 1:
The system dynamically adjusts communication mode based on real-time monitoring of battery levels during data transmission. When battery level drops below the threshold during active use, the system automatically switches from wireless LAN to mobile communication mode, enabling adaptive performance adjustment that preserves battery life while maintaining acceptable communication speeds
Solution Approach 2:
The patent implements a feedback mechanism where battery level information is continuously monitored and fed back to the communication selection logic. This feedback loop enables the system to respond to changing power conditions and adjust communication methods accordingly, preventing battery depletion while maintaining optimal performance when power is available
3Use of energy by moving object
If communication method is automatically selected based on battery level, then power consumption is reduced, but user choice is limited
Solution Approach 1:
The system performs self-service by automatically monitoring battery levels and selecting appropriate communication methods without requiring continuous user intervention. The automatic selection mechanism handles power management decisions autonomously, reducing user burden while still providing transparent options through notifications, thereby combining automated power saving with user autonomy
Data Source
AI summary
An apparatus and method for reducing the power consumed by mobile communication terminal having a wireless LAN connection function. When a data communication operation is started, a control unit determines whether a connection to a wireless LAN is available, and if so, detects the battery remaining amount in a battery unit. If the battery remaining amount is equal to or greater than a first threshold, data communication is performed through the wireless LAN connection. When the battery remaining amount is smaller than the first threshold, a screen for recommending connection through cellular communication is displayed on a display unit. When the battery remaining amount becomes smaller than a second threshold, which is smaller than the first threshold, a power source control unit performs a predetermined power saving operation.
