Home Appliance Control Device for Proximity-Based Notification Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart home appliances' user interfaces, such as LCDs and speakers, are underutilized, and mobile devices frequently interrupt users with notifications, causing discomfort, especially during tasks like gaming or calls when urgent notifications are missed.
Innovation Solution
A home appliance control device that detects a user's proximity using Bluetooth Low Energy signals and controls nearby appliances to output messages, ensuring notifications are delivered via the nearest appliance within range, preventing interruptions and optimizing interface usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notifications are delivered via mobile device, then information can be transmitted to user, but user experience deteriorates due to interruptions during gaming or calls
Solution Approach 1:
The patent introduces a notification management server as an intermediary between the notification source and the user's mobile device. This server receives notifications, determines the user's current activity state, and selectively redirects notifications to alternative output devices (TV, refrigerator, etc.) when the user is engaged in activities like gaming or calling, thereby preventing interruptions while ensuring information delivery
2Productivity
If user interface in home appliances is utilized for general notifications, then interface usage efficiency improves, but device complexity increases
Solution Approach 1:
The patent enables home appliance user interfaces (TV display, refrigerator display, etc.) to serve multiple functions: their original dedicated functions plus general notification display. The notification management server sends notification information to these appliances, allowing them to function as universal information display devices without requiring complex modifications to each individual appliance
Solution Approach 2:
The notification management server acts as a central coordinator that manages the complexity of routing notifications to multiple different home appliances. Instead of each appliance needing complex logic to determine when to display notifications, the server handles the decision-making and simply sends notification data to appropriate appliances, keeping individual appliance complexity low
3Ease of operation
If notifications are blocked during user activities, then user experience improves by reducing interruptions, but information delivery reliability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the notification management server continuously monitors the user's current activity state (gaming, calling, etc.) and uses this feedback to dynamically adjust notification delivery. When the user is engaged in an activity, notifications are redirected to home appliances; when the user is available, notifications are delivered to the mobile device, ensuring reliable information delivery adapted to real-time user state
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces user disruption by delivering notifications through nearby home appliances, enhancing the user experience by minimizing interruptions and efficiently utilizing smart home interfaces.
Implementation Method 1
calculate a distance between the mobile device and each of the at least one home appliance, based on a strength of a Bluetooth low energy (BLE) communication signal between the mobile device and each of the at least one home appliance
Data Source
AI summary
Provided is a home appliance control device including: a communication interface; and at least one processor configured to transmit, based on a message output standby request being received from a mobile device, the message output standby request to at least one home appliance via the communication interface, determine whether a user exists within a first distance from at least one of the at least one home appliance, and control, based on determining that the user exists within the first distance from a first home appliance from among the at least one home appliance, the first home appliance to output a message corresponding to the message output standby request.
