Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle driver assistance systems, imaging device failures in electronic mirrors often go unnoticed, leading to impaired system operation and reduced convenience, as users cannot easily detect these failures without professional inspection.
Innovation Solution
An electronic mirror system that includes an imaging device with a failure detector and notifier, which communicates with the electronic mirror to announce detected failures, prompting users to address the issues and maintain proper system operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging device is integrated into electronic mirror system, then driver assistance capability is improved, but failure detection capability deteriorates
Solution Approach 1:
The patent introduces a notifier as an intermediary component between the imaging device and the electronic mirror. The notifier receives failure information from the imaging device and transmits it to the electronic mirror, enabling failure detection without adding complexity to the core imaging function. This mediator resolves the contradiction by providing a dedicated communication channel for failure information.
Solution Approach 2:
The system implements a feedback mechanism where the imaging device monitors its own operational status and feeds back failure information to the electronic mirror through the notifier. This feedback loop enables real-time failure detection and notification, allowing the system to maintain high adaptability while improving failure detection capability through continuous status monitoring.
2Reliability
If failure detection function is added to imaging device, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the failure detection and notification functions into a separate notifier module that is distinct from the core imaging device. The imaging device focuses on image acquisition while the notifier handles failure detection and communication with the electronic mirror. This segmentation improves reliability through dedicated failure monitoring while preventing complexity from accumulating in the imaging device itself.
Solution Approach 2:
The imaging device performs self-diagnosis by monitoring its own operational status and generating failure information. This self-service capability enables the device to detect its own failures without requiring external monitoring systems, thereby improving reliability while minimizing the addition of external complexity. The notifier then handles the communication aspect of this self-detected information.
