Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric recognition systems in vehicles do not consider the road environment or user habits and preferences when granting access, leading to inefficiencies and potential safety issues.
Innovation Solution
An unlocking system that integrates imaging devices to capture surrounding environment and user data, generates a high-definition map, and uses biometric recognition to identify users based on their habits and preferences, adjusting access permissions and providing feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional biometric recognition systems are used to identify users, then user identification can be achieved, but the system does not consider road environment or user habits leading to reduced safety and user experience
Solution Approach 1:
The system performs preliminary actions by capturing images of the road environment and generating a contextual map before user identification occurs. This pre-processing of environmental data allows the system to evaluate safety conditions and user habits in advance, making the identification process more reliable and context-aware without adding delay to the actual authentication.
Solution Approach 2:
A contextual map is introduced as an intermediary element that bridges the gap between basic biometric recognition and environmental awareness. This map serves as a mediator that integrates road environment data, user habits, and safety parameters, allowing the system to make informed authentication decisions without requiring direct complex interactions between all system components.
2Adaptability or versatility
If environmental imaging and map generation are added to enhance contextual awareness, then safety and user experience improve, but device complexity increases
Solution Approach 1:
The imaging device is designed with multi-functionality, serving both as a standard biometric recognition camera and as an environmental mapping device. By making the imaging system universal, the patent avoids adding separate dedicated sensors for environmental capture, thereby reducing overall system complexity while still achieving enhanced contextual awareness through the same hardware component.
3Measurement precision
If confidence score verification with threshold comparison is implemented, then identification accuracy improves, but processing time increases
Solution Approach 1:
The system applies partial verification by using confidence score threshold comparison only when necessary, rather than always performing full verification. This selective approach allows the system to maintain high identification accuracy for uncertain cases while avoiding unnecessary processing time for clear, unambiguous identifications, thus balancing precision with speed.
