Optical Sensor System for Passive Vehicle Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle authentication systems require users to actively detect and approach a control panel or perform specific actions to initiate an authentication check, which is time-consuming and inefficient.
Innovation Solution
An optical sensor system that monitors a detection area outside the vehicle to recognize users' proximity and initiate an authentication check passively, eliminating the need for additional sensors and allowing authentication to occur unnoticed or early, using infrared light and image processing to define a specific detection area and trigger authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If an optical sensor system is used to monitor a detection area and automatically trigger authentication when a user is recognized, then the authentication check can be initiated earlier and without user intervention, but the device complexity increases due to the need for optical sensors and image processing capabilities
Solution Approach 1:
The patent replaces mechanical/contact-based authentication initiation (user touching a control panel or pressing a button) with an optical detection system that automatically recognizes users through image processing. The optical sensor system captures images in the detection area and triggers authentication based on user recognition, eliminating the need for physical user actions to initiate the process.
Solution Approach 2:
The optical sensor system continuously monitors the detection area before the user reaches the vehicle, enabling early recognition and automatic triggering of the authentication check. This preliminary detection and automatic initiation occurs before the user would normally need to take any action, thus reducing authentication initiation time.
2Adaptability or versatility
If the detection area is limited to a specific spatial segment using optical sensors, then authentication can be targeted to specific users approaching from certain directions, but the coverage area is reduced compared to omnidirectional sensors
Solution Approach 1:
The patent defines a specific detection area as a spatial segment in front of the vehicle where the optical sensor system monitors for users. This localized detection zone allows the system to focus computational resources on recognizing users within this specific area, providing targeted authentication while reducing unnecessary monitoring of other regions.
