Solution Overview
Problem
Multifunction peripherals face challenges in reducing power consumption effectively in response to power reduction requests, particularly in environments focused on energy management and global warming mitigation, where existing systems lack efficient methods to balance performance and energy savings.
Innovation Solution
An image processing apparatus with a power management module that controls various functions such as printing and scanning to restrict performance based on received power reduction requests, using a power reduction control matrix to adjust parameters like speed and resolution, ensuring energy savings without compromising operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If performance of output unit or reading unit is restricted to reduce power consumption, then power consumption is reduced, but productivity decreases
Solution Approach 1:
The system dynamically adjusts the performance parameters (such as processing speed, resolution, or capacity) of the output unit or reading unit based on the received power reduction request. The third controller modifies operational parameters in real-time to balance power consumption and productivity requirements, allowing the system to adapt its performance level according to energy management needs while maintaining acceptable operational efficiency.
2Loss of energy
If performance is restricted to satisfy power reduction request, then energy efficiency is improved, but operability deteriorates
Solution Approach 1:
The system changes operational parameters (such as processing speed, resolution, capacity, or power level) of the output unit or reading unit in response to power reduction requests. By adjusting these parameters, the system achieves better energy efficiency while maintaining sufficient operability for intended tasks, allowing flexible optimization of the balance between energy consumption and functional performance.

AI summary
An image processing apparatus includes a first controller, a second controller, and a third controller. The first controller controls an output unit that outputs an image. The second controller controls a reading unit that reads an image. The third controller controls, in response to receipt of a power reduction request, the first controller or the second controller to restrict performance of the output unit or the reading unit so as to satisfy the power reduction request.
