Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple sensor sources transmit data through a shared interface, then data processing capability is improved, but data integrity and compatibility across different frame formats deteriorate
Solution Approach 1:
The patent segments the interface architecture into distinct functional blocks: multiple sensor sources (first sensor source, second sensor source), separate data assemblers (first data assembler, second data assembler), and a shared sensor interface queue. Each sensor source and data assembler operates independently with its own frame format, while the shared queue provides unified access. This segmentation allows multiple data streams to be processed simultaneously without interfering with each other's integrity, resolving the contradiction between improved productivity and maintained reliability.
Solution Approach 2:
The shared sensor interface queue acts as an intermediary between multiple sensor sources and the processing system. It receives data packets from different sensor sources in different frame formats, buffers them, and manages their transmission to respective data assemblers. This intermediary component isolates the sensor sources from each other, allowing them to operate independently while still enabling efficient shared access to the interface, thus improving productivity without compromising data integrity.
2Productivity
If a shared sensor interface queue is used for multiple sensor links, then interface efficiency is improved, but complexity of managing multiple frame formats increases
Solution Approach 1:
The patent applies local quality by assigning specific frame format handling capabilities to specific data assemblers rather than requiring a universal format converter. The first data assembler is configured to assemble data in a first frame format from the shared queue, while the second data assembler assembles data in a second frame format. Each data assembler has specialized logic for its required format, simplifying the overall system compared to a single complex format conversion mechanism, thus improving interface efficiency while managing format complexity through localized specialization.
Solution Approach 2:
The shared sensor interface queue provides universal access functionality, serving multiple sensor links and multiple data assemblers simultaneously. It implements a unified data structure and transmission protocol that can accommodate data from different sensor sources with different frame formats. This multi-functional queue eliminates the need for separate dedicated interfaces for each sensor link, improving interface efficiency while the standardized queue interface abstracts away the complexity of handling multiple frame formats.
3Reliability
If error detection is implemented in data assemblers, then data reliability is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary action by performing error detection at the data assembler stage, immediately after data packets are assembled from the shared sensor interface queue but before the data is processed by the signal processor. The first data assembler detects errors in the first frame format data, and the second data assembler detects errors in the second frame format data. This timing allows error detection to occur in parallel with data assembly operations, minimizing additional processing time while ensuring data reliability before further processing occurs.
