Power Supply Control for Image Processing Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems for image processing apparatuses lack efficient mechanisms to dynamically manage power states based on user presence, leading to unnecessary power consumption and inefficient energy usage.
Innovation Solution
A power supply control apparatus that includes motion sensors to detect user presence, allowing for selective and individual power management of processing units, transitioning them to powered-on or powered-off states accordingly, and incorporating a controller to manage these states based on user detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all processing units are powered on continuously, then the image processing apparatus can respond immediately to user operations, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by transitioning processing units between powered-on and powered-off states based on real-time user presence detection. When no user is detected, units are powered off to save energy; when a user is detected, units are powered on to ensure immediate response. This dynamic state adjustment resolves the contradiction between continuous readiness and energy conservation.
Solution Approach 2:
The system uses motion sensors to automatically detect user presence and trigger power state transitions without manual intervention. The processing units self-adjust their power states based on sensor inputs, eliminating the need for users to manually power units on or off, thus resolving the contradiction through automated self-service behavior.
2Loss of energy
If motion sensors are used to detect user presence, then power management becomes more efficient, but device complexity increases
Solution Approach 1:
The motion sensor serves multiple functions: it detects user presence for power management, and can potentially be used for other security or automation features. By making the sensor multi-functional, the patent justifies the added complexity through enhanced versatility and energy efficiency benefits.
Solution Approach 2:
The system implements feedback by continuously monitoring motion sensor outputs and adjusting power states accordingly. The sensor provides real-time feedback about user presence, which the controller uses to make informed decisions about powering units on or off, thereby achieving energy efficiency despite the added complexity.
3Use of energy by moving object
If processing units are powered off when not in use, then energy consumption decreases, but response time when user returns increases
Solution Approach 1:
The system performs preliminary action by detecting user approach through motion sensors before the user actually interacts with the device. When motion is detected, the system proactively powers on processing units in advance, ensuring immediate responsiveness when the user arrives, thus eliminating the trade-off between energy saving and response time.
