Power Supply Control with Manual Override and Timer Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems prioritize manual operation over schedule settings, leading to conflicts and inefficiencies when users override scheduled power on/off times.
Innovation Solution
A power supply control apparatus and recording apparatus that integrate a first power supply unit, a second continuous power supply unit, a controller, a timer, and an operation unit to manage power based on both user operations and scheduled settings, ensuring priority to user inputs while adhering to scheduled power transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power supply control is based solely on schedule setting, then energy efficiency is improved, but usability deteriorates when users need to manually override scheduled times
Solution Approach 1:
The system dynamically adjusts power supply control by allowing users to override scheduled settings through manual operation of the power key. The control unit detects power key operations and modifies the scheduled power supply plan accordingly, enabling the system to adapt between automated energy-saving mode and manual user control based on real-time needs.
2Ease of operation
If both power key and scheduling function control power supply, then usability is improved, but control complexity increases due to potential conflicts between manual and scheduled operations
Solution Approach 1:
The control unit continuously monitors both scheduled power supply timing and power key operations, providing feedback processing that resolves conflicts between manual and automated control. When a power key operation is detected, the system processes this input against the scheduled plan and adjusts the power supply control accordingly, ensuring coherent decision-making despite multiple control inputs.
3Loss of time
If the timer operates continuously with dedicated power supply, then scheduling accuracy is improved, but energy consumption increases
Solution Approach 1:
The timer operates periodically rather than continuously, being activated only when needed for power supply control decisions. The timer is triggered based on scheduled power supply timing and power key operations, allowing it to maintain scheduling accuracy while consuming energy only during active periods rather than continuously.

AI summary
A power supply control apparatus comprises a first power supply supplying power to a controller and a second power supply supplying power to an operation unit and a power controller. The operation unit receives an operation for switching the first power supply on and off. The power controller is operable to turn on the first power supply according to the signal from a timer or the operation by the operation unit, and to turn off the first power supply according to a state of the controller. The controller, upon at least either of the operation by the operation unit or the signal from the timer, performs a setting to the timer of a time at which to turn on the power from the first power supply or a time at which to turn off the power from the first power supply.
