Solution Overview

Problem

Current smart home systems lack integrated, intelligent, and network-connected devices that can seamlessly communicate to provide comprehensive home security and automation, leading to inefficiencies in managing visitors, security alerts, and energy management.

Innovation Solution

The development of intelligent, multi-sensing, network-connected devices such as smart thermostats, hazard detectors, doorbells, wall switches, and entry detectors that communicate with each other and a central server or cloud-computing system to provide automated control and feedback, enabling enhanced security, energy management, and visitor handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional separate security and automation systems are used, then device simplicity is maintained, but system integration and communication efficiency deteriorate

Engineering Contradiction:
Improvesystem integrationVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate security and automation devices into a unified smart home system where entry detectors, doorbells, thermostats, and hazard detectors all communicate through a common mesh network, enabling integrated control and shared intelligence across previously separate systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The smart home devices are designed with multi-functionality, where a single device can serve multiple purposes - for example, the entry detector not only detects visitors but also integrates with the doorbell, security system, and automation routines, allowing one device to perform what previously required multiple specialized devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If manual visitor management is used, then system complexity is reduced, but visitor handling efficiency and security response deteriorate

Engineering Contradiction:
Improvevisitor handling efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system provides self-service capabilities where visitors can interact with the smart doorbell, view displays, and receive automated responses without manual intervention from homeowners, while the system automatically manages detection, notification, and coordination between various security and automation devices

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback loops where the entry detector communicates visitor information to the doorbell and security system, which then provide automated responses and notifications back to visitors and homeowners, creating an intelligent feedback mechanism that improves visitor handling without requiring manual system management

Inventive Principle:
Principle #23Feedback

3Reliability

If basic security devices are used, then device cost is reduced, but real-time monitoring and alert capabilities deteriorate

Engineering Contradiction:
Improvesecurity alert reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The smart home devices use periodic communication and event-triggered updates rather than continuous monitoring, where devices like entry detectors and thermostats transmit data periodically or when state changes occur, maintaining reliable security monitoring while reducing overall energy consumption compared to continuous active monitoring systems

Inventive Principle:
Principle #19Periodic action
