Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses, such as multifunction peripherals, face challenges in providing flexible state control and efficient power management due to the difficulty in accurately determining user proximity and preferences, leading to increased user burden and inefficient power consumption.
Innovation Solution
The apparatus employs a communication unit to receive beacon signals from terminal devices, using multiple reference distances to dynamically control the display mode and power states based on proximity and user authentication, history, and type information, allowing for flexible and efficient display and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single reference distance is used to control display mode, then the control logic is simple, but the flexibility to adapt to different user situations is insufficient
Solution Approach 1:
The single reference distance is segmented into multiple reference distances (first reference distance, second reference distance, third reference distance) to create distinct control zones. This segmentation allows the system to provide different display modes and power states for different proximity levels, thereby improving adaptability without requiring complex conditional logic within a single threshold
Solution Approach 2:
The system changes the parameter of reference distance from a single value to multiple values, creating a gradient of proximity thresholds. This parameter change enables flexible state control by mapping different distance ranges to different display modes and power consumption states, resolving the contradiction between simplicity and flexibility
2Ease of operation
If the display is always on to provide user convenience, then user convenience is improved, but power consumption increases
Solution Approach 1:
The display state is made dynamic by introducing multiple reference distances that define different operational modes. The system automatically transitions between display-on and display-off states based on the terminal's proximity to the electronic apparatus, providing user convenience when needed while conserving power when the user is absent
Solution Approach 2:
The system uses parameter changes in reference distance thresholds to control the transition between power-consuming display states and power-saving off states. By comparing the terminal's distance against multiple reference distances, the system optimizes the balance between user convenience and power consumption
3Adaptability or versatility
If multiple reference distances are used to improve flexibility, then state control flexibility is improved, but the determination complexity increases
Solution Approach 1:
The distance determination is segmented into multiple discrete thresholds (first, second, and third reference distances) rather than requiring continuous precision measurement. This segmentation simplifies the detection process by creating clear zones for different control behaviors, reducing the complexity of distance measurement while maintaining flexible control

AI summary
An electronic apparatus includes: a communication unit that receives a beacon signal from a terminal apparatus; a display unit; and a processing unit that performs display processing of the display unit. The processing unit performs processing of displaying a screen to be displayed to a user of the terminal apparatus from which the beacon signal is transmitted, on the display unit, in a first display mode, in a case where it is determined that a distance between the terminal apparatus and the electronic apparatus is equal to or shorter than a first reference distance based on a reception radio wave intensity of the beacon signal.
