Solution Overview

Problem

Existing security systems require users to interact with interfaces on the exterior of premises to disarm alarms or unlock doors, which can be inconvenient and may not leverage the capabilities of mobile devices for streamlined control.

Innovation Solution

A wireless-power receiving device installed at the premises receives identification information from a mobile device upon wireless power transfer, transmitting this information to a remote device to request operation of the security system, enabling authentication and authorization processes to control security functions without direct user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users interact with exterior interfaces (keypads, intercoms, key fobs) to control security functions, then security control capability is provided, but user convenience deteriorates and operation complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidinterface complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the security control functionality from traditional exterior interfaces (keypads, intercoms) and relocates it to the user's mobile device. The mobile device becomes the primary interface, while the exterior device is reduced to a minimal power and communication receiver, eliminating the need for complex exterior user interfaces.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mobile device serves multiple functions: it provides wireless power to the exterior device via NFC inductive coupling, transmits identification information for authentication, and communicates control commands. This multi-functional approach consolidates security control capabilities into a universal device users already carry.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If traditional wired power and communication interfaces are installed at premises, then security system operation is enabled, but installation cost and maintenance cost increase

Engineering Contradiction:

Improveinstallation costVSAvoidsystem operation capability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces wired mechanical power and communication interfaces with wireless NFC-based inductive coupling. The exterior device receives power and communicates with the mobile device wirelessly, eliminating the need for complex wiring infrastructure while maintaining reliable operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mobile device itself provides the power needed by the exterior device through wireless power transfer. The exterior device does not require separate power wiring or complex power management infrastructure, as it is powered on-demand by the user's mobile device when needed.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If mobile devices are used for security control, then user convenience and flexibility improve, but power supply to exterior devices becomes problematic

Engineering Contradiction:

Improvecontrol flexibilityVSAvoidpower supply capability

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The exterior device acts as an intermediary that temporarily stores and manages power transfer from the mobile device. The NFC inductive coupling enables wireless power transfer from the mobile device to the exterior device, which then uses this power for its operations and communications.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary authentication and power transfer preparation before actual security control operations. The mobile device establishes NFC coupling with the exterior device first, ensuring power availability and authentication before executing security commands, thereby preventing power-related failures during critical operations.

Inventive Principle:

Principle #10Preliminary action
