Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems for image processing devices are inefficient in utilizing multiple power sources and do not effectively reduce energy consumption during sleep modes, leading to suboptimal energy savings.
Innovation Solution
A power supply control device that switches between commercial power and energy storage systems, using a monitoring unit to determine when internal power consumption falls below a specified value, allowing the third power supply section to take over and maintaining power in ordinary mode, while suppressing power consumption of the third power supply section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the main power source is turned off and only standby power source is used during energy saving mode, then energy consumption is reduced, but power supply reliability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating power supply strategies for different system components. During energy saving mode, the main power source is turned off while the standby power source continues to supply power to the control system and necessary circuits. This selective power distribution maintains reliability for critical functions while reducing overall energy consumption.
Solution Approach 2:
The patent implements preliminary action by having the control system detect power source status and pre-arrange power supply switching before complete power failure occurs. The system monitors power source availability and transitions between main and standby power sources proactively, ensuring continuous reliable operation without interruption.
2Reliability
If multiple power source systems are used, then power supply reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the main power source and standby power source into a unified power supply system with integrated control. The control system consolidates monitoring and switching functions, managing both power sources through a single control architecture. This merging approach maintains reliability benefits while minimizing the complexity increase that would result from completely separate control systems.
Solution Approach 2:
The control system is designed with multi-functionality to handle both normal operation and energy saving mode control. It performs power source monitoring, switching control, and system management functions universally across different operating conditions. This universal control approach reduces the need for separate dedicated control circuits for each power source scenario.

AI summary
A power supply control device including a mode switching controller, a first power supply section, a second power supply section, a third power supply section, a wiring system opening and closing unit and a controller. During the sleep mode, the first power supply section continues to supply power to a specific control system, the second power supply section shuts off its supply of power, and the third power supply section supplies power to the specific control system by a separate system to the specific control system. The wiring system opening/closing unit sets a power supply wiring system of the commercial power source to an open state or a closed state. When the third power supply section is supplying power during the sleep mode, the controller controls the wiring system opening and closing unit and sets the power supply wiring system of the commercial power supply to the open state.
