Wrist-Worn Mobile Terminal Voice Control Vehicle Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack efficient methods for controlling vehicles using voice commands and secure user authentication, particularly in wearable devices, which complicates optimized user experience and security when transmitting control rights to external terminals.
Innovation Solution
A wearable mobile terminal with a wrist-worn design, featuring a display unit, input unit for voice commands, and a control unit that outputs vehicle-related screen information based on voice inputs, performs user authentication, and transmits control signals to vehicles or external terminals through short-range communication, ensuring secure and optimized vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is implemented for vehicle control, then ease of operation is improved, but reliability deteriorates due to authentication security concerns
Solution Approach 1:
The patent replaces traditional mechanical authentication methods (physical keys, buttons) with voice recognition technology. The voice recognition unit detects and processes user voice commands to authenticate and control vehicle functions, substituting physical interaction with acoustic field-based recognition, thereby improving ease of operation while maintaining security through voice pattern verification
Solution Approach 2:
The patent changes the authentication parameter from physical presence (mechanical key insertion, button pressing) to acoustic characteristics (voice frequency, tone, speech patterns). The voice recognition unit analyzes these acoustic parameters to verify user identity, enabling contactless authentication that improves operational convenience while ensuring reliability through voice-specific biometric verification
2Adaptability or versatility
If control right is transmitted to external terminal, then adaptability is improved, but security deteriorates
Solution Approach 1:
The patent introduces a control right transmission mechanism that acts as an intermediary between the vehicle control system and external terminals. Instead of direct control access, the system transmits authenticated control rights through a secure communication interface, allowing external devices to control vehicle functions only after proper authentication, thereby enabling adaptability while maintaining security through the intermediary authorization layer
Solution Approach 2:
The patent implements preliminary authentication and control right verification before allowing external terminal access. The voice recognition unit authenticates the user in advance, and the control system pre-issues authorized control rights to the external terminal based on verified user permissions, ensuring that only authenticated users can transmit control commands, thus maintaining security while enabling versatile control transmission
