Portable Electronic Apparatus Pseudo Power-Off Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices in a pseudo power-off state cannot utilize most functions, making it difficult to handle emergency situations effectively since the power supply is not fully cut off, limiting the use of functions like position information transmission.
Innovation Solution
A portable electronic apparatus with a setting section that enables a pseudo power-off mode where only the crime prevention function is active, allowing the device to switch to a full power-on mode when the crime prevention function is used, thereby enabling all functions, including position information transmission, without physically turning on the power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply is turned off immediately after communication with an emergency facility, then power consumption is reduced and device is secured, but position information or other functions cannot be acquired making it difficult to cope with emergency situations
Solution Approach 1:
The patent implements a dynamic power management system that allows the device to switch between different power states (normal operation, pseudo power-off, and actual power-off) based on operational context. The control section dynamically adjusts power supply to various components while maintaining the ability to quickly restore full functionality when needed for emergency responses.
Solution Approach 2:
The patent segments the power supply control into different levels: full power mode, pseudo power-off mode (where only display and operating sections are restricted), and actual power-off mode. This segmentation allows selective maintenance of functions during power-reduced states, ensuring emergency capabilities remain accessible even when the device appears powered off.
2Loss of energy
If a power-off operation is received within a predetermined time after audio communication line is disconnected, then power consumption is reduced, but most variety of functions cannot be used requiring users to perform operations for turning on power supply
Solution Approach 1:
The patent prepares the device for quick recovery by maintaining certain subsystems in a low-power ready state during pseudo power-off mode. The control section and transmitting/receiving sections remain partially operational, so when power restoration is needed, the device can quickly transition back to full functionality without requiring complete re-initialization, thus reducing time loss.
3Loss of energy
If the power supply is turned off in a pseudo manner, then power consumption is reduced, but most of the variety of functions cannot be used
Solution Approach 1:
The patent applies local quality by differentiating power supply status across different components of the device. During pseudo power-off mode, the display section and operating section are restricted, but the control section, transmitting/receiving section, and crime prevention function remain operational. This localized power management allows specific functions to remain available while reducing overall power consumption.

AI summary
A portable electronic apparatus is provided. The portable electronic apparatus includes a display section, an operating section, a setting section which switches and sets, based on an operation to the operating section, a pseudo power-off mode in which electric power is not supplied to the display section and a crime prevention function is enabled and a power-on mode in which the electric power is supplied to the display section and entire functions including the crime prevention function are enabled, and a control section which switches the pseudo power-off mode into the power-on mode when the crime prevention function is used in a state where the pseudo power-off mode is set by the setting section.
