Communication Device Display State Control for Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of information processing devices struggle to identify which communication device among multiple devices is indicated by information displayed on an external device, leading to confusion in selecting the correct device.
Innovation Solution
A specific communication device is equipped with a communication interface for wireless communication, a display unit, and a controller. The controller sends specific identification information to an external device, and upon receiving this information, the display unit changes its state from a first state (not displaying the identification information) to a second state (displaying the identification information), allowing users to recognize which device the information corresponds to.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the information processing device displays a list of communication device information, then the user can recognize the existence of multiple communication devices, but the user cannot identify which communication device each piece of information indicates
Solution Approach 1:
The patent introduces a display unit as an intermediary component between the communication interface and the user. This display unit receives identification information from the communication interface and presents it in a visually accessible format, mediating the information flow to make device identification possible without complicating the core communication functionality
Solution Approach 2:
The communication device performs self-identification by automatically displaying its own identification information through the display unit. The device serves itself by presenting its identity without requiring external assistance or complex user queries, thereby resolving the information loss while maintaining system simplicity
2Ease of operation
If the display unit continuously displays identification information, then the user can easily identify the device, but the energy consumption increases
Solution Approach 1:
The display unit operates periodically rather than continuously, displaying identification information only when triggered by specific conditions such as receiving a request from an external device or detecting nearby devices. This periodic operation maintains ease of identification when needed while significantly reducing energy consumption during idle periods
Solution Approach 2:
The display unit transitions between different operational states (displaying vs. non-displaying) based on dynamic conditions. The controller adjusts the display state according to real-time requirements, making the system adaptable to balance user convenience and energy efficiency rather than operating in a fixed continuous mode

AI summary
A specific communication device may send specific identification information for identifying the specific communication device to an external via a communication interface, wherein the external device may display a screen including the specific identification information in a case where the external device receives the specific identification information from the specific communication device; and in a case where a specific condition including that the specific identification information is sent to the external is fulfilled, a state of the display unit may be changed from a first state to a second state, the first state being a state in which the display unit does not display the specific identification information, and the second state being a state in which the display unit displays the specific identification information.
