Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional black box system is installed in the container transport apparatus, then event recording capability is provided, but the SD memory card life is very short and storage space is partitioned by case
Solution Approach 1:
The patent changes the recording mode from case-based partitioned recording to continuous recording without partitioning. The storage space is no longer divided by case types, allowing more efficient utilization of SD memory card capacity and extending its operational life while maintaining reliable event recording capability.
2Measurement precision
If only acceleration sensors are used for event detection, then vibration changes can be identified, but images for various error conditions cannot be secured
Solution Approach 1:
The patent merges multiple detection methods by combining acceleration sensors with camera systems. While acceleration sensors continue to detect vibration changes, cameras are added to capture images of various error conditions, ensuring comprehensive event documentation without losing visual information.
Solution Approach 2:
The event recording system is enhanced to perform multiple functions: detecting vibration through acceleration sensors and simultaneously capturing visual evidence through cameras. This multi-functional approach ensures both precise measurement and comprehensive information retention for different types of errors.
3Ease of operation
If black boxes are set only through touch screen panels, then user interface is provided, but remote setup and updates are difficult requiring SD memory card separation
Solution Approach 1:
The system enables remote setup and updates through network connectivity, allowing the black box to configure itself and receive firmware updates without requiring physical SD memory card removal or on-site technician intervention. This reduces operational complexity while maintaining ease of use through the existing touch screen interface.
4Ease of operation
If vehicle-related data is not displayed on the black box screen, then display simplicity is maintained, but separate access is required to identify vehicle-related data
Solution Approach 1:
The black box display is enhanced to serve multiple functions: it continues to maintain its simple interface for basic operations while also displaying vehicle-related data directly on the screen. This allows operators to access both event recording information and vehicle status information without separate access procedures, reducing time loss while preserving display simplicity.
