Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems for devices like image processing apparatuses lack efficient automation in transitioning from power-saving modes to operational states when a person approaches, leading to unnecessary power consumption and inefficient device activation.
Innovation Solution
A power supply control apparatus incorporating a person presence sensor, an access camera, and a recognition camera that detect a person's approach and activate necessary devices only when confirmed, ensuring minimal power usage during sleep modes and efficient operation when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the device enters power saving mode to reduce power consumption, then energy efficiency is improved, but the response speed when a person approaches deteriorates
Solution Approach 1:
The imaging unit is divided into two functional segments: a first imaging unit for capturing approach images and a second imaging unit for capturing recognition images. This segmentation allows the system to process images at different stages of detail, reducing the need for continuous high-power operation while maintaining responsive detection capability.
Solution Approach 2:
The control unit performs preliminary actions by first capturing an image with the first imaging unit when motion is detected, then using that image to determine whether to activate the second imaging unit. This staged approach prepares the system for potential full operation without immediately consuming maximum power, thus improving response speed while managing energy usage.
2Measurement precision
If the first imaging unit captures images continuously to detect person approach, then detection accuracy is improved, but power consumption increases
Solution Approach 1:
The control unit employs periodic action by capturing images only at specific intervals when motion is detected by the sensor, rather than continuously. The first imaging unit captures images periodically based on motion detection triggers, and the second imaging unit captures images only when needed based on the first unit's results, significantly reducing overall power consumption while maintaining detection accuracy.
Solution Approach 2:
The system uses partial action by capturing images at different levels of detail through the two imaging units. The first imaging unit captures sufficient images for motion detection and approach determination, while the second imaging unit captures additional detailed images only when necessary for recognition, avoiding excessive action and associated power consumption.
3Reliability
If both imaging units are activated simultaneously to ensure operational readiness, then system reliability is improved, but device complexity increases
Solution Approach 1:
The control unit performs preliminary evaluation by first using the first imaging unit to capture an image and determine whether a person is approaching. Based on this preliminary result, the control unit then decides whether to activate the second imaging unit. This staged activation ensures operational readiness through reliable detection while managing control complexity through sequential decision-making rather than simultaneous activation of all components.

AI summary
A power supply control apparatus includes a sensor, a first imaging unit, a second imaging unit, and a state controller. The sensor senses a person when the power supply control apparatus is in a power saving state. The first imaging unit consumes higher power than the sensor and captures an image of a person approaching. The second imaging unit captures an image used to recognize a person. The state controller causes the first imaging unit and the second imaging unit to be in a power supply state in a case where the sensor has sensed a person.
