Power-Supply Control Device for Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-supply control systems for image processing apparatuses lack efficient mechanisms to dynamically adjust power states based on usage patterns, leading to unnecessary power consumption and inefficient energy management.
Innovation Solution
A power-supply control device with a power-supply-state transition control section, multiple body-capable-of-movement detection sections, a time measuring section, and an instruction-provision-time postponement section, which dynamically shifts the operation target section between power-supply states and a non-power-supply state based on usage detection and timer settings, postponing transitions when a user is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the system transitions to non-power-supply state after a predetermined idle time, then power consumption is reduced, but user convenience deteriorates when users return unexpectedly
Solution Approach 1:
The system dynamically adjusts the power supply state based on real-time detection of user presence. When a user is detected within the predetermined time period, the system remains in the power-supplied state; when no user is detected, it transitions to the non-power-supplied state. This dynamic adaptation resolves the contradiction by making the system responsive to actual usage conditions rather than following a fixed timeline.
Solution Approach 2:
The detection section provides continuous feedback about user presence to the control section. This feedback mechanism allows the system to monitor the surrounding environment and adjust its power supply state accordingly, ensuring that power is not cut off when users are present while still achieving power savings when the system is truly idle.
2Measurement precision
If multiple detection sections with different detection conditions are used, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The detection function is segmented into multiple detection sections, each with specific detection conditions. This segmentation allows the system to detect different types of user presence or environmental changes with specialized sensors, improving overall detection accuracy while maintaining manageable complexity through modular design.
Solution Approach 2:
The multiple detection sections work together as an integrated detection system that provides comprehensive monitoring. By designing the detection sections to be part of a unified control architecture, the system achieves multi-functional detection capabilities without proportionally increasing overall complexity, as the control section coordinates all detection inputs through a single decision-making process.

AI summary
A power-supply control device includes a power-supply-state transition control section, body-capable-of-movement detection sections, a time measuring section, a transition-instruction section, and an instruction-provision-time postponement section. The power-supply-state transition control section shifts a state of an operation target section from one state to another state among power-supply states and a non-power-supply state. The body-capable-of-movement detection sections detect a body capable of movement in a region. The time measuring section measures a time over which the operation target section in one of the power-supply states is not used. The transition-instruction section provides, for the power-supply-state transition control section, an instruction for shifting to the non-power-supply state. The instruction-provision-time postponement section postpones an instruction-provision time at which the instruction is provided by the transition-instruction section.
