Radio Wave Learning for Automated Home Occupancy Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home security systems require manual user intervention to transition between modes and lack an automated mechanism to determine if occupants are present, making them less efficient and more complex to manage.
Innovation Solution
An information processing apparatus that records and learns radio wave information from various terminals in a house, allowing it to automatically distinguish the presence of occupants and control the operating state of house management systems by comparing newly detected radio wave information with learned patterns, switching modes as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual user intervention is required to transition between security modes, then system control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically detects occupant presence using radio wave information from terminals and autonomously transitions between security modes without requiring manual user intervention. The control section learns radio wave patterns from multiple terminals and automatically determines when the house is occupied or unoccupied, enabling the system to serve itself rather than requiring continuous user control.
Solution Approach 2:
The patent replaces manual mechanical operation (user pressing buttons or switches) with an automated detection and control system. The control section uses radio wave detection and pattern recognition to substitute for manual user actions in transitioning between security modes, thereby improving operational convenience while maintaining detection accuracy through learned terminal patterns.
2Ease of operation
If automated occupant presence detection is implemented, then ease of operation is improved, but device complexity deteriorates
Solution Approach 1:
The system uses existing multi-functional terminals (smartphones, tablets, computers) that users already possess for other purposes. These terminals serve dual functions: their primary communication function and their role as radio wave emission sources for occupancy detection. The control section learns from radio waves emitted by these universal devices, avoiding the need for dedicated detection hardware and reducing overall system complexity.
Solution Approach 2:
The patent introduces radio wave information as an intermediary medium between the terminals and the control system. Instead of direct complex communication protocols or dedicated sensors, the system uses readily available radio wave emissions from terminals as a simple intermediary carrier of occupancy information, simplifying the detection mechanism while maintaining automated operation capability.
3Measurement precision
If radio wave information from multiple terminals is learned and compared, then occupant presence detection accuracy is improved, but loss of information increases
Solution Approach 1:
The control section performs preliminary learning of radio wave information patterns from multiple terminals during an initial phase. By pre-learning and storing characteristic radio wave patterns from each terminal beforehand, the system prepares the necessary information in advance, reducing the need for continuous data storage and processing during operation. This preliminary action improves detection accuracy while managing information storage requirements.
