Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rearview mirror assemblies for vehicles lack integrated biometric scanning capabilities to securely identify vehicle operators, relying on conventional methods that are not secure or efficient for modern vehicle systems.
Innovation Solution
A biometric scanning apparatus is integrated into the rearview mirror assembly, featuring a display housing with an image sensor and a support housing that forms a cavity for a PCB, allowing for multi-axial rotation and thermal isolation, utilizing infrared illumination for iris scanning and processing biometric data to identify vehicle occupants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric scanning capabilities are integrated into the rearview mirror assembly, then vehicle security and identification efficiency are improved, but device complexity increases
Solution Approach 1:
The patent integrates the biometric scanning apparatus (including image sensor, infrared illuminator, and processing electronics) directly into the rearview mirror assembly housing, combining multiple functions (mirror display, biometric scanning, and vehicle identification) into a single integrated unit. This merging approach improves vehicle security through reliable biometric authentication while managing device complexity by consolidating components rather than adding separate systems.
2Adaptability or versatility
If an image sensor and processing electronics are integrated into the mirror assembly, then biometric identification capability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the mirror assembly into distinct functional modules: a display housing containing the image sensor and infrared illuminator, a support housing containing the first PCB with processing electronics, and a connection interface. This segmentation allows each module to be manufactured and tested separately before final assembly, improving biometric identification capability while reducing overall manufacturing complexity through modular production.
Solution Approach 2:
The patent employs a nested structure where the display housing with the image sensor is positioned within the support housing that contains the processing electronics. The connection interface allows these nested components to communicate while maintaining compact integration. This nesting approach enables sophisticated biometric identification capability while managing manufacturing complexity through hierarchical assembly.
3Adaptability or versatility
If the display housing is connected to the support housing with adjustable connection interface, then adaptability and positioning flexibility are improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic connection interface between the display housing and support housing that allows for adjustable positioning and multi-axial rotation. This dynamic connection enables the display housing to be positioned at optimal angles for both driver visibility and biometric scanning accuracy, improving positioning flexibility while managing connection interface complexity through a designed degree of freedom in the mounting mechanism.
