Solution Overview

Problem

Parents face challenges in monitoring and ensuring the safety and behavioral compliance of their children, particularly when they are not at home, as existing security and automation systems lack comprehensive tracking and identification features for individuals entering and exiting the residence.

Innovation Solution

A security and automation system that detects entry and exit events, tracks actions, compares them to predetermined profiles, and confirms identities using biometric features, unique mobile devices, or entry codes, while also providing alerts and locking down potential hazards, allowing parents to monitor their children's activities and safety remotely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If comprehensive tracking and identification features are added to security systems, then monitoring capability is improved, but device complexity increases

Engineering Contradiction:
Improvemonitoring capabilityVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses behavioral patterns as an intermediary to identify individuals. Instead of directly using complex biometric sensors, the system mediates identification through analysis of movement patterns, routine behaviors, and action sequences, which can be captured by simpler existing sensors while achieving reliable identification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system continuously monitors actions and compares them against stored behavioral profiles, providing real-time feedback for identification. This feedback mechanism allows the system to refine its monitoring accuracy over time without requiring proportional increases in hardware complexity.

Inventive Principle:
Principle #23Feedback

2Reliability

If multiple identification methods (biometric, mobile device, entry code) are implemented, then identification reliability is improved, but device complexity increases

Engineering Contradiction:
Improveidentification reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system dynamically selects which identification method to use based on the situation. It can switch between behavioral pattern recognition, biometric verification, mobile device detection, and entry code validation depending on context, allowing reliable identification while avoiding the need to always activate all complex identification systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The identification system is segmented into multiple independent methods that can operate separately or in combination. Each method (behavioral analysis, biometric verification, mobile device tracking, code validation) is a discrete module that can be activated independently, reducing overall system complexity while maintaining reliability through selective use.

Inventive Principle:
Principle #1Segmentation

3Reliability

If real-time tracking of children's actions is implemented, then safety monitoring is improved, but loss of time for data processing increases

Engineering Contradiction:
Improvesafety monitoringVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-processing and storing behavioral patterns during normal periods. When safety monitoring is needed, this pre-prepared data allows for rapid comparison and identification without requiring extensive real-time data processing, thus maintaining high safety monitoring capability while minimizing data processing time delays.

Inventive Principle:
Principle #10Preliminary action

AI summary

Security and/or automation systems, collectively referred to as automation systems, may allow a parent to leave their child at home and feel comfortable. The automation system may receive a notification that the parents are leaving. The parents may set a child alone state or a babysitter state. The system may use settings determined by the parents to track child parameters. Restricted areas may include a parents liquor cabinet, a parents bedroom, an office, and the like. The automation system may additionally track the comings and goings of a child to determine if the child is out past a curfew, when the child left, when the child arrived at home, and the like. Additionally, the parent away state may implement a lock down on any firearms or other potential hazards in a home.
