Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming systems face challenges in maintaining low power consumption while providing high convenience, particularly when using visible light communication for augmented reality displays, as they require continuous light emission from image forming apparatuses even in low power modes, leading to increased power consumption.
Innovation Solution
The system employs a dual communication mode, where visible light communication is used for augmented reality displays and normal communication is used for power-saving modes, allowing the image forming apparatus to switch off light emitters during low power modes and resume only when requested by the information terminal, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visible light communication is used for augmented reality displays, then communication convenience is improved, but power consumption increases due to continuous light emission
Solution Approach 1:
The system dynamically switches between visible light communication and normal communication modes based on operational requirements. The image forming apparatus transitions from continuous light emission in visible light mode to discontinuous light emission in normal mode, adapting its communication method to balance convenience and power consumption.
Solution Approach 2:
Visible light communication is activated periodically or on-demand rather than continuously. The apparatus switches to visible light mode when augmented reality display is needed and returns to normal mode otherwise, creating a periodic action pattern that reduces overall power consumption while maintaining communication convenience when required.
2Adaptability or versatility
If light emitters are kept on for visible light communication, then augmented reality display functionality is maintained, but power consumption increases
Solution Approach 1:
The light emitter operates dynamically, switching between on and off states based on the required communication mode. When augmented reality functionality is needed, the light emitter is activated for visible light communication; otherwise, it remains off or operates at reduced power in normal communication mode, maintaining versatility while reducing energy consumption.
Solution Approach 2:
The system applies different operational qualities to the light emitter based on local requirements. In visible light communication mode, the light emitter operates at full capability to provide augmented reality functionality. In normal mode, the light emitter operates with reduced or no light emission, applying local quality adjustment to match functional requirements and minimize power consumption.

AI summary
An image forming system includes an image forming apparatus having a light emitter and an information terminal performing visible light communication and normal communication with the image forming apparatus. The image forming apparatus includes a visible light output unit outputting information stored in the image forming apparatus through visible light communication using the light emitter, and an output control unit controlling operation of the visible light output unit. The information terminal includes a light receiver, and an information acquisition unit acquiring visible light communication information based on information obtained by receiving visible light with the light receiver. The information acquisition unit gives a light emission communication start request to the output control unit through the normal communication with the image forming apparatus. When the light emission communication start request is received and the visible light output unit is stopping outputting information, the output control unit allows output of information.
