Solution Overview

Problem

Conventional user interfaces for electronic access control systems, such as keypads and credential readers, are time-consuming and may not provide adequate security or ease of use, particularly in scenarios where hands-free operation is desired.

Innovation Solution

A system that utilizes a mobile device with a transceiver, such as Bluetooth or NFC, to receive spoken commands and authenticate users, allowing secure communication with a reader device to control electronic locks, enabling hands-free operation and enhanced security through voice recognition and location-based authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional keypads or credential readers are used for user identification, then the system provides basic access control functionality, but the operation time is excessive and user convenience is reduced

Engineering Contradiction:
Improveuser convenienceVSAvoidoperation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces mechanical input methods (keypads, credential readers) with voice-based acoustic input. The mobile device captures spoken commands through its microphone, processes them locally, and transmits the interpreted intent to the access control system, eliminating the need for physical interaction with traditional interfaces.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables users to initiate access control operations through natural speech without requiring manual device manipulation. The mobile device autonomously captures, processes, and transmits the voice command, allowing hands-free operation particularly beneficial when users have full hands or need rapid access.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If voice commands are used for hands-free operation, then user convenience is improved, but system security may be compromised without proper authentication

Engineering Contradiction:
Improvehands-free operationVSAvoidsystem security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary authentication by verifying the mobile device's identity and authorization status before processing voice commands. The access control system validates the transmitted voice data against authorized user profiles, ensuring that only authenticated users can initiate access operations through voice commands.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mobile device acts as an intermediary between the user's voice input and the access control system. It captures the acoustic signal, processes it locally to extract meaningful commands, and transmits only the interpreted intent to the access control system, adding a layer of security by filtering and validating input before transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Use of energy by moving object

If the mobile device remains in low-power or locked state during voice command input, then energy consumption is reduced and security is maintained, but the device must quickly activate to process the command

Engineering Contradiction:
Improveenergy consumptionVSAvoidactivation speed
Core Design Contradiction:
Use of energy by moving objectVSSpeed

Solution Approach 1:

The system uses periodic wake-up triggers where the mobile device remains in low-power state and only activates briefly when triggered by specific events (such as approaching the access control system or receiving a wake signal). This allows the device to maintain low energy consumption while being ready to process voice commands when needed.

Inventive Principle:
Principle #19Periodic action

AI summary

A mobile device is configured to wirelessly authenticate with a reader device. The mobile device may receive an acoustic signal from a user, and a command may be determined based on the acoustic signal. The mobile device may transmit the command to the reader device if the mobile device and the reader device are authenticated. The reader device may receive the command, and may analyze the command to determine an action to be performed. The reader device may then perform the action if the mobile device is authorized to request the command to be performed.
