Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If image capturing apparatus are installed at higher locations to eliminate occlusion, then the field of view and detection capability are improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The monitoring host is designed to perform multiple functions including receiving image data from multiple sources, synchronizing time stamps, determining object locations, predicting movements, and providing information to multiple road users. This multi-functional design consolidates what would otherwise require separate systems, reducing overall installation complexity while maintaining comprehensive field of view coverage
Solution Approach 2:
The patent introduces a monitoring host as an intermediary component that centralizes the processing of image data from multiple high-location cameras. This intermediary handles synchronization, object detection, and information distribution, making the complex system more manageable and easier to install by providing a single point of control rather than requiring complex peer-to-peer coordination between multiple independent systems
2Reliability
If multiple separate systems are used for traffic monitoring, speed detection, and parking management, then each function can be optimized, but the system complexity and cost increase
Solution Approach 1:
The monitoring host is designed as a universal platform that performs multiple traffic management functions including monitoring object positions, detecting speeding violations, managing parking spaces, and providing information to road users. By consolidating these functions into a single system rather than using separate dedicated systems for each function, the patent reduces overall system complexity while maintaining the reliability needed for each specific function through specialized processing algorithms
Solution Approach 2:
The patent merges previously separate traffic management functions into a unified system. The monitoring host combines image data processing, object detection, speed measurement, parking management, and information distribution into a single integrated platform. This merging reduces the number of separate systems needed, simplifies infrastructure requirements, and lowers overall system complexity while maintaining functional reliability through dedicated processing for each function type
3Measurement precision
If real-time synchronization of image data from multiple sources is implemented, then the accuracy of object location determination is improved, but the processing complexity and time requirements increase
Solution Approach 1:
The monitoring host implements a feedback mechanism where time stamp information from each image data source is used to calculate and apply synchronization adjustments. The system continuously monitors the timing of incoming image data, identifies desynchronization, and applies corrective transformations to align all data to a common time reference. This feedback loop enables accurate synchronization without requiring complex pre-coordination between multiple independent processing systems
Solution Approach 2:
The patent applies preliminary synchronization transformations to image data before proceeding with object detection and location determination. By pre-aligning the time references of multiple image sources and predicting object positions based on synchronized data, the system simplifies subsequent processing steps. This preliminary action ensures that all downstream processing works with already-synchronized data, reducing overall processing complexity
4Reliability
If more sensors are added to autonomous vehicles to improve detection in bad weather, then the detection capability is improved, but the device complexity and power consumption increase
Solution Approach 1:
The monitoring host acts as an external intermediary that provides enhanced detection capabilities to autonomous vehicles without requiring additional sensors on the vehicles themselves. The host system captures images from elevated positions, processes the data to detect objects, road conditions, and weather-related hazards, then transmits this processed information to vehicles. This approach gives AVs access to enhanced detection reliability while avoiding the complexity and power consumption of adding multiple specialized sensors to each vehicle
