Display Apparatus BLE Signal Scanning for Ambient Service Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses controlled via wireless communication, such as BLE, often fail to accurately meet user intentions regarding the operation of ambient services, leading to inconvenience when a registered user is not present, causing unnecessary termination of ambient services for other users.
Innovation Solution
A control method and apparatus that utilize BLE signals to determine the presence of a registered mobile device, allowing the ambient service to continue even when the registered user is not nearby, by scanning for BLE signals at specific intervals and maintaining the service unless explicitly ended by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display apparatus terminates ambient service when a registered mobile device is not detected, then power consumption is reduced and device is controlled securely, but user convenience deteriorates when other users are present without the registered device
Solution Approach 1:
The patent divides the user base into registered users and unregistered users, and segments the control logic accordingly. The display apparatus detects different user types through mobile device identification and applies different termination rules: registered users trigger service termination when absent, while unregistered users do not trigger termination. This segmentation resolves the contradiction by allowing differentiated control strategies for different user groups.
Solution Approach 2:
The patent implements dynamic control of ambient service termination based on real-time detection of mobile device presence and user registration status. The termination policy is not fixed but adapts dynamically: the service termination function is activated for registered users and deactivated for unregistered users. This dynamic approach allows the system to maintain reliability for registered users while preserving convenience for unregistered users.
2Measurement precision
If the display apparatus continuously scans for BLE signals to detect mobile device presence, then user intention detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent employs periodic scanning of BLE signals at predetermined intervals rather than continuous scanning. The controller periodically checks for mobile device presence and uses this information to determine whether to terminate ambient service. This periodic action maintains adequate detection accuracy for controlling ambient service while significantly reducing energy consumption compared to continuous scanning.
