Fingerprint Reader Push-Button Switch Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle identification systems using key fobs are often inaccurate due to shared fobs, unauthorized use, or incorrect detection of passengers, leading to improper configuration of vehicle systems.
Innovation Solution
Integration of a biometric fingerprint reader into a user interface that captures fingerprint data to accurately identify the driver and configure vehicle systems according to their preferences, combining with a push-button switch and a vehicle processor to manage system settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If key fob identification is used to identify the driver, then the system is simple to operate, but the identification accuracy deteriorates due to shared fobs, unauthorized use, or incorrect detection
Solution Approach 1:
The patent replaces the mechanical/key-based identification system with a biometric fingerprint recognition system. The fingerprint sensor captures unique physiological characteristics of the driver's finger, providing accurate identification without relying on physical key fobs that can be shared or stolen. This substitution maintains ease of operation while dramatically improving identification accuracy.
Solution Approach 2:
The patent introduces a biometric authentication intermediary between the driver and the vehicle systems. Instead of directly using key fob signals, the system mediates identification through fingerprint verification, ensuring that only authorized drivers can access and configure vehicle settings. This intermediary layer eliminates the problems of shared fobs and unauthorized access.
2Measurement precision
If biometric fingerprint reader is integrated into the user interface, then the identification accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent merges the fingerprint sensor with the existing push-button user interface component. By integrating the biometric sensor into the familiar button structure, the system adds identification functionality without creating separate complex devices. The merged design maintains simplicity while enabling accurate driver identification.
Solution Approach 2:
The patent makes the push-button interface multi-functional by incorporating both the mechanical button functionality and the biometric sensing capability into a single component. This universal design allows the same physical interface to serve multiple purposes: button pressing for activation and fingerprint capture for identification, thereby reducing overall system complexity.
Data Source
AI summary
A user interface is provided. The interface can be used to control an electronic system that is in communication with a vehicle. The interface includes a fingerprint reader, and a push-button switch mounted to the fingerprint reader. The switch is configured to detect a user pressing upon a surface of the fingerprint reader. The interface includes a controller. The controller is configured to detect the user pressing upon the surface of the fingerprint reader using the push-button switch, and, after detecting the user pressing upon the surface of the fingerprint reader, capture fingerprint data of the user using the fingerprint reader.
