Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a local processing unit is added to the detector module, then data processing capability and encryption function are improved, but device complexity increases
Solution Approach 1:
The patent merges the local processing unit with the detector module by integrating it into the read-out circuit architecture. The processing unit shares physical space and electrical connections with existing detector components, combining multiple functions (detection, read-out, processing, encryption) into a unified module structure rather than adding separate standalone components.
Solution Approach 2:
The local processing unit is designed to perform multiple functions including data processing, encryption, and control operations within a single integrated component. This multi-functional approach allows the system to gain enhanced capabilities without proportionally increasing the number of separate devices or components.
2Reliability
If data encryption is implemented in the local processing unit, then data security is improved, but processing time increases
Solution Approach 1:
The encryption function is integrated into the data transmission pathway at the source, performing encryption immediately when data leaves the detector module. This preliminary action ensures security is established early in the data flow without requiring additional processing steps later in the system.
Solution Approach 2:
The patent replaces traditional centralized encryption approaches with a distributed, hardware-based encryption implementation in the local processing unit. This substitution uses dedicated cryptographic circuits rather than software-based encryption, providing faster processing with lower computational overhead.
3Adaptability or versatility
If programmable intelligence is added to the detector module, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The programmable processing unit is implemented as a modular component that can be independently fabricated and then integrated with the detector module. This segmentation allows standard semiconductor manufacturing processes to be used for both the detector and processing components separately, simplifying production while enabling post-assembly programming and configuration.
Solution Approach 2:
The processing unit is designed with configurable parameters and programmable logic that can be adjusted after manufacturing. This allows the same hardware platform to adapt to different applications and requirements through software or configuration changes rather than requiring different physical components for each application.
