Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a translation facility is implemented to support diverse camera configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a translation facility as an intermediary layer between the host processor and the camera sensor. This translator converts host commands into sensor-specific commands and manages metadata storage, thereby supporting diverse camera configurations without requiring the host processor to directly handle each sensor's unique protocol. The translator acts as a mediator that abstracts the complexity from the host while maintaining adaptability to various sensor types.
2Adaptability or versatility
If legacy sensors are supported through translation, then adaptability is improved, but loss of time in command execution occurs
Solution Approach 1:
The patent implements a metadata storage subsystem that pre-stores translation rules and command mappings for various sensor types including legacy sensors. By having this translation information readily available in metadata storage rather than computing it in real-time, the system can quickly translate host commands to sensor-specific commands even for legacy sensors, reducing the time penalty associated with supporting older sensor architectures.
3Ease of manufacture
If a standardized command set is implemented, then ease of manufacture is improved, but adaptability to specific sensor configurations decreases
Solution Approach 1:
The patent creates a universal translation facility that can handle multiple sensor types and configurations through a single standardized interface. The translation layer is designed to be multi-functional, supporting not only current sensor architectures but also legacy and future sensor types. This universal approach allows manufacturers to use a standardized command set while maintaining adaptability to specific sensor configurations through the flexible translation mechanism.
Data Source
AI summary
The present disclosure provides techniques for executing a command within a transport mechanism based on a get and set architecture. An attribute identification of the command is extracted and a get protocol data unit (PDU) is sent from a host device to a imaging device based on the attribute identification in order to obtain attribute values from an image source within the imaging device. Additionally, a response PDU is sent from the imaging device to the host device to complete the execution of the command.
