Information Processing Apparatus Power Saving Lock Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses face inefficiencies in power saving due to unintended lock modes caused by program terminations, leading to inconvenient operation transitions and reduced power saving efficiency.
Innovation Solution
An information processing apparatus with a check unit that periodically assesses program activity and a cancel unit that unlocks operations when a program is inactive for a given period, preventing unnecessary prohibition of power-saving mode transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If periodical check is performed to cancel locks from terminated programs, then power saving efficiency is improved, but operation stability deteriorates when resuming process occurs simultaneously
Solution Approach 1:
The system performs preliminary action by checking program activity status before allowing power-saving mode transition. The determination unit assesses whether a program that applied lock is active or inactive before the lock is canceled, and only cancels the lock when the program is confirmed inactive, preventing premature cancellation during resuming processes
Solution Approach 2:
The system implements feedback mechanism where the determination unit continuously monitors program activity status and uses this information to control the lock cancellation timing. The feedback from program status checking allows the cancel unit to make informed decisions about when to safely cancel locks, balancing power saving with operational stability
2Productivity
If lock is canceled when program becomes inactive, then power saving mode transition is enabled, but program operation continuity is disrupted during resuming process
Solution Approach 1:
The determination unit performs preliminary assessment of program activity status before lock cancellation. By checking whether the program is truly inactive (not in resuming process) before canceling the lock, the system prevents disruption of program operation continuity while still enabling power saving mode transition when appropriate
Solution Approach 2:
The system dynamically adjusts lock cancellation timing based on real-time program status detection. The cancel unit delays lock cancellation until the determination unit confirms the program is inactive, creating a dynamic control mechanism that adapts to program lifecycle states and prevents operational disruption

AI summary
An information processing apparatus (10) includes a check unit (201, 111, 134) and a cancel unit (201, 111, 135). The check unit (201, 111, 134) checks whether a program is active at plural timings. The program is previously terminated while keeping prohibition of at least one operation of the information processing apparatus. The cancel unit (201, 111, 135) cancels the prohibition of the at least one operation of the information processing apparatus when the program remains inactive for a given period of time.
