Smart Home Presence Recognition for Personalized Appliance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart home systems lack the ability to differentiate between family members' preferences and activities, leading to inefficient control of home appliances and lack of personalized suggestions for events, which hampers user convenience and security.
Innovation Solution
A smart home control system that uses sensors and a host to identify family members entering or leaving the home, linking their IDs to control switches and agendas stored in memory, allowing for personalized control of appliances and notifications based on member IDs and event recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smart home system performs basic controls of home appliances and lamps, then the system can operate with simple control logic, but it cannot provide personalized controls for different family members
Solution Approach 1:
The patent segments the control system by family member, with each member having their own ID, preference profile, and associated control rules. The host device processes sensor data to identify which family member is present and applies personalized control rules accordingly, enabling differentiated control without requiring a completely separate system for each member.
Solution Approach 2:
The system performs preliminary actions by pre-configuring control rules and preferences for each family member before they enter the home. When a member is detected via sensors, the host device automatically retrieves their pre-stored preferences and executes appropriate control actions, eliminating the need for real-time decision-making complexity.
2Productivity
If the system detects multiple different events, then it can monitor comprehensive home activities, but it cannot identify relationships between events to provide integrated suggestions
Solution Approach 1:
The host device continuously receives feedback from multiple sensors detecting different events (motion, temperature, light, etc.). It processes this feedback to identify relationships between events, such as detecting that a family member entering the home (motion event) combined with the time of day should trigger specific appliance controls and agenda items. This feedback loop enables integrated suggestions without losing event relationship information.
3Ease of operation
If the system stores correspondence relationships between family members and control switches in memory, then it enables personalized control, but it increases memory requirements and system configuration complexity
Solution Approach 1:
The patent implements a universal control framework where a single host device and centralized memory structure serve all family members. The correspondence relationships between members, switches, and agendas are stored in a unified data structure that can accommodate any number of family members and their preferences, rather than requiring separate configuration systems for each member.
Data Source
AI summary
There is provided a smart home control system including a host, at least one sensor, a plurality of controlled devices and an informing device. The host identifies entering and leaving of family members according to detection results of the at least one sensor, and controls on/off of the controlled devices or informs a specific family member by the informing device to execute agenda according to a member ID of a family member who is identified to enter or leave the house.
