Power Management for Image Processing Apparatus Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face challenges in efficiently managing power consumption, as they often require high power states for operation, leading to increased energy usage and reduced power saving effects, especially when transitioning between different operational modes.
Innovation Solution
The image processing apparatus includes multiple functioning units with the ability to switch between high and low power states, with a controlling unit that manages these transitions based on specific timing settings for each type of processing, allowing for optimized power management by transitioning to low power states after job completion, thereby reducing overall power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus maintains high power state for operation, then user convenience and response speed are improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the power state adjustable and transitionable between high and low states based on operational context. The controlling unit dynamically switches power states of functioning units according to whether the control receiving unit is in high or low power state, optimizing the balance between responsiveness and energy savings.
Solution Approach 2:
The patent applies local quality by allowing different functioning units to be in different power states independently. The controlling unit can selectively transition specific functioning units between high and low power states based on their current state and the operational context, rather than uniformly managing all units.
2Loss of energy
If the apparatus transitions to low power state quickly, then power saving effect is improved, but standby time increases
Solution Approach 1:
The patent uses dynamics to adjust the transition timing based on the power state of the control receiving unit. When in high power state, units transition after a first set time; when in low power state, they transition after a second set time, dynamically optimizing the balance between power savings and standby duration.
Solution Approach 2:
The patent implements periodic action through timed transitions between power states. The controlling unit transitions functioning units to low power state after predetermined time intervals (first set time or second set time), creating a rhythmic pattern of high and low power states that balances energy savings with operational readiness.
3Loss of energy
If different set times are used for high and low power states, then power saving optimization is improved, but control complexity increases
Solution Approach 1:
The patent applies parameter changes by using different time parameters (first set time and second set time) based on the power state of the control receiving unit. The controlling unit adjusts the transition timing parameter according to whether the control unit is in high or low power state, optimizing power savings through parameter variation.
Solution Approach 2:
The patent implements self-service by having the controlling unit automatically determine which set time to use based on the current power state of the control receiving unit. The system autonomously selects the appropriate timing parameter without requiring external intervention, simplifying control while maintaining optimization.

AI summary
An image processing apparatus includes a plurality of functioning units each having a reception functioning unit, a control receiving unit and a controlling unit. Each of the reception functioning unit and the control receiving unit has a high power state and a low power state as an operational state, respectively. In a case that the control receiving unit is in the high power state, the controlling unit transits the operational state of the functioning unit from the high power state to the low power state when a first set time elapses after an execution of a processing is terminated. In another case that the control receiving unit is in the low power state, the controlling unit transits the operational state of the functioning unit from the high power state to the low power state when a second set time elapses after the execution of the processing is terminated.
