Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle imaging devices prioritize convenience over safety, failing to provide crash avoidance functionalities promptly, especially during vehicle startup, which is critical for enhanced safety and autonomous driving technologies.
Innovation Solution
An imaging device with a prioritization mechanism that starts safety-related software programs before others, utilizing a priority table to ensure rapid execution of safety functionalities upon vehicle ignition, thereby reducing startup time and enhancing safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If safety-related software programs are started prior to other software programs, then the time to provide safety functionalities is reduced, but the device complexity increases due to priority management mechanisms
Solution Approach 1:
The patent applies preliminary action by pre-defining priority levels for different software programs before execution. The start unit is configured to identify and start safety-related software programs first based on predetermined priority settings, ensuring that safety functionalities are available immediately upon device activation without waiting for other programs to load.
Solution Approach 2:
The patent segments the software startup process into priority-based groups. Instead of starting all software programs simultaneously or in a fixed sequence, the system divides programs into different priority levels (with safety-related programs assigned highest priority) and starts them in segmented batches according to their priority classification.
2Adaptability or versatility
If multiple software programs are loaded into memory, then the functionality and versatility of the device is improved, but the memory requirement increases
Solution Approach 1:
The patent applies preliminary action by pre-loading only the most critical safety-related software programs into memory at startup, while other programs can be loaded on-demand or from external storage. This ensures that essential safety functionalities are immediately available in memory without requiring all possible software to be permanently resident.
Solution Approach 2:
The patent implements a nested memory structure where frequently used and high-priority software programs are stored in main memory, while less frequently used or lower-priority programs are stored in external storage or secondary memory. The system nests these storage layers, allowing quick access to critical functions while maintaining the capability to load additional functionality as needed.
