Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack an effective solution for providing unobstructed digital rear view monitoring and digital video recording, especially when rear visibility is obstructed by loading boxes or other obstructions.
Innovation Solution
A video processing system connected to front and rear camera modules, featuring a digital rear mirror module for displaying rear view videos, a memory for storing videos, and a processor for transmitting and processing video feeds, allowing for digital rear view monitoring and recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple camera devices are installed to provide digital rear view monitoring and video recording, then the reliability and functionality are improved, but the device complexity and installation cost increase
Solution Approach 1:
The rear camera module is designed to serve multiple functions: it provides both digital rear view monitoring (DRM) by transmitting video to the digital rear mirror module, and digital video recording system (DVRS) by storing video in the memory. This multi-functionality eliminates the need for separate camera devices for each function, reducing overall system complexity while maintaining reliability
Solution Approach 2:
The patent combines the DRM and DVRS functions into a single integrated system using one rear camera module. The camera module simultaneously feeds video signals to both the digital rear mirror module for real-time monitoring and the memory for recording, merging multiple functions into a unified architecture that reduces device quantity and installation complexity
2Reliability
If multiple camera devices and cables are installed, then comprehensive monitoring coverage is improved, but the installation time and cost increase
Solution Approach 1:
The single rear camera module performs multiple functions (DRM and DVRS) simultaneously, eliminating the need for multiple separate camera installations. This reduces installation time while maintaining comprehensive monitoring coverage through the unified system architecture
3Reliability
If multiple camera devices are installed, then the monitoring coverage is improved, but the vehicle weight increases
Solution Approach 1:
By designing the rear camera module to serve both DRM and DVRS functions simultaneously, the system eliminates redundant camera devices and their associated mounting hardware. This single multi-functional camera reduces the overall weight added to the vehicle while maintaining comprehensive monitoring coverage
