Vehicle Door Voice Recognition Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door opening and closing systems using remote controls or manual switches are inefficient, particularly when the user has their hands full, and lack secure vocal command recognition to prevent unauthorized access and the ability to close the door.
Innovation Solution
A voice recognition system integrated with a microcontroller-based mechanism that samples and recognizes specific vocal commands to control the opening and closing of vehicle doors, using a microcontroller to generate signals for the mechanical control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote controls or manual switches are used to open vehicle doors, then the door can be opened, but the system is inefficient when the user has their hands full
Solution Approach 1:
The patent replaces manual switches and remote controls with a voice recognition system that uses acoustic signals to trigger door opening. The microcontroller samples voice frequency patterns and compares them against stored patterns to enable hands-free operation, directly substituting mechanical input methods with acoustic field-based control.
2Ease of operation
If vocal commands are used to open vehicle doors, then hands-free operation is enabled, but unauthorized access cannot be prevented
Solution Approach 1:
The patent applies local quality by making the voice recognition system selective to specific individuals. The microcontroller stores frequency patterns from authorized users and compares incoming voice samples against these specific patterns. Only voices matching the stored patterns can trigger door opening, providing localized security for each authorized user while maintaining hands-free operation.
3Device complexity
If conventional mechanical systems are used for door control, then the system is simple, but the ability to close the door via vocal command is lacking
Solution Approach 1:
The patent implements universality by enabling the voice recognition system to perform multiple functions: opening the door with one vocal command and closing the door with another. The microcontroller is programmed to recognize different voice patterns for different actions, allowing a single system to control both opening and closing operations without requiring separate mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a simple, efficient, and secure method for opening or closing vehicle doors using vocal commands, preventing unauthorized access and allowing hands-free operation while ensuring secure access control.
Implementation Method 1
a microcontroller based components which is attached to a vehicle door, initially samples the voice frequency pattern of a number of individuals and then develops an average frequency pattern from the sample
Data Source
AI summary
A device that either opens or closes the rear door of a vehicle depending upon the specific vocal commands of a user.
