Voice Input Detection Prevents Power Saving State Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with power saving functions often interrupt applications like voice chat when they enter a suspend state due to inactivity, which is inconvenient for users engaged in voice conversations.
Innovation Solution
An electronic device with a manipulation receiving unit and a voice receiving unit that prevents the device from entering a power saving state if voice input is detected during a predetermined non-operation time period, allowing voice chat applications to continue uninterrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the device enters a power saving state when no user manipulation is detected for a predetermined time, then power consumption is reduced, but application execution is interrupted
Solution Approach 1:
The patent applies dynamics by making the power saving state transition conditional rather than fixed. The system dynamically adjusts its behavior based on real-time detection of voice input, allowing the device to remain in active state when voice communication is detected and transition to power saving state only when truly idle, thus resolving the contradiction between power consumption and application continuity
Solution Approach 2:
The patent implements feedback by continuously monitoring for voice input signals and using this feedback to prevent power saving state transition. When voice input is detected, the system receives feedback that the device should remain active, and this feedback mechanism prevents the harmful effect of application interruption while still enabling power saving when appropriate
2Productivity
If the device switches to power saving state autonomously after predetermined inactivity, then energy efficiency is improved, but user convenience deteriorates during voice chat
Solution Approach 1:
The patent applies preliminary action by detecting voice input before the power saving state transition can occur. The system monitors for voice signals in advance and prevents the power saving transition from happening during voice chat, ensuring user convenience is maintained while still achieving energy efficiency when the device is truly idle
Solution Approach 2:
The patent uses voice input detection as an intermediary mechanism between user activity and power state management. This intermediary prevents direct conflict by detecting voice signals and using them to mediate the power saving decision, allowing the system to balance energy efficiency with user convenience during voice communication

AI summary
Manipulation receiving unit receives an operation input by a user manipulation. In case the manipulation receiving unit does not receive an input operation for a predetermined time period, a state control unit sets an operation state to a power saving state. However, if the voice receiving unit receives voice input before a non-operation time period reaches the predetermined time period, the status control unit does not set the operation state to the power saving state even if the manipulation receiving unit does not receive an input operation during the predetermined time period. The non-operation time period is defined as a time period during which the manipulation receiving unit does not receive an input operation.
