Portable Terminal Sleep Mode Timer Notice Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face inconvenience when entering sleep mode during data gathering, as the transition to sleep mode can be frequent with large content volumes, leading to unnecessary power consumption or user inconvenience when waking the device.
Innovation Solution
A method and apparatus that display a notice screen before entering sleep mode, allowing users to temporarily reset the sleep mode timer, thereby preventing the device from switching to sleep mode until the new timer expires, enhancing user convenience and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sleep mode timer is set to a short duration to avoid frequent wake-ups, then user convenience is improved, but unnecessary power consumption increases due to frequent sleep mode transitions
Solution Approach 1:
The system performs preliminary action by displaying a notice screen before the sleep mode timer expires, giving the user advance warning and an opportunity to extend the timer. This prevents unnecessary sleep mode transitions by allowing users to proactively adjust settings before the automatic transition occurs, thereby avoiding frequent wake-ups and reducing power consumption.
2Loss of energy
If the sleep mode timer is set to a long duration to reduce power consumption, then energy efficiency is improved, but user convenience deteriorates due to frequent wake-ups when gathering content
Solution Approach 1:
The system applies dynamics by making the sleep mode timer adjustable and flexible rather than fixed. The notice screen provides users with the ability to dynamically change the timer setting based on their current needs, allowing the system to adapt between energy efficiency and user convenience depending on the situation.
3Loss of energy
If the portable terminal enters sleep mode automatically to reduce power consumption, then energy efficiency is improved, but user convenience deteriorates when the user needs to check operations or gather content
Solution Approach 1:
The system implements feedback by displaying a notice screen that informs users of the upcoming sleep mode transition. This feedback mechanism allows users to be aware of the timer status and take action to extend it if needed, creating a closed-loop system that responds to user needs while maintaining energy efficiency.

AI summary
A method of controlling a sleep mode of a portable terminal is provided. The method includes setting a sleep mode timer according to a default setting; displaying, upon reaching a predetermined time point before expiration of the sleep mode timer, a notice screen including the sleep mode timer and a timer setting area for re-setting the sleep mode timer according to a temporary setting; and entering, when a sleep mode timer temporary resetting command is received while the notice screen is displayed, a screen maintaining mode in which the sleep mode timer is temporarily re-set from the default setting to a temporary setting according to the sleep mode timer temporary resetting command.
