Dashboard Fingerprint Authentication for Keyless Mobile Carrier Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile carriers, such as vehicles, face difficulties in operation and user identity management when the key or remote control is lost or forgotten, as they lack a method to identify users and perform function settings accordingly.
Innovation Solution
Integration of an ultrasonic fingerprint identification assembly within the dashboard device, which includes a fingerprint sensor, controller, and flexible printed circuits, covered by a functional interface layer with a shield layer and a light-transmitting protection plate, allowing for fingerprint authentication even when the key or remote control is absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key or remote control is used for mobile carrier operation, then the mobile carrier can be operated and driven, but the system cannot identify user identity or perform user-specific function setting and management
Solution Approach 1:
The dashboard device integrates multiple functions into a single system: it serves as both the mobile carrier operation interface and the user identity identification system. The ultrasonic fingerprint sensor enables the dashboard to perform dual roles of vehicle control and user authentication, eliminating the need for separate key systems while adding user-specific management capabilities
2Reliability
If the key or remote control is lost or forgotten, then the mobile carrier cannot be operated and driven, but adding alternative authentication methods increases system complexity
Solution Approach 1:
The patent replaces the mechanical key system with an ultrasonic fingerprint recognition system. The ultrasonic sensor uses acoustic waves to capture fingerprint patterns, converting a mechanical authentication method into an acoustic field-based method. This substitution maintains reliability by providing alternative access when keys are lost, while the integrated nature of the dashboard device keeps complexity manageable
3Measurement precision
If an ultrasonic fingerprint identification assembly is integrated into the dashboard device, then user identity can be identified through fingerprint, but the assembly requires careful positioning and spacing from the functional interface layer
Solution Approach 1:
The patent applies local quality by creating a specific spatial zone for the ultrasonic fingerprint sensor with controlled acoustic properties. By positioning the sensor at a precise distance (greater than 0.15mm) from the functional interface layer and using cushion material with specific acoustic impedance, the system optimizes ultrasonic wave transmission locally at the sensor location without affecting the overall dashboard structure
Solution Approach 2:
The cushion material serves as an intermediary between the ultrasonic fingerprint sensor and the functional interface layer. This intermediate layer manages acoustic impedance matching and protects the sensor while maintaining the required spacing, simplifying the integration process by providing a standardized interface component that handles the complex acoustic coupling requirements
