Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless tag communication apparatus uses reading device and antenna to read tag data, then tag information can be obtained, but reading accuracy may be insufficient and cannot detect all tags in disposed region
Solution Approach 1:
The disposed region is divided into multiple sub-regions, and the antenna is moved to different positions to read tags in each sub-region separately. This segmentation allows comprehensive coverage of the entire disposed region while maintaining high reading accuracy in each local area, resolving the contradiction between reading accuracy and detection reliability.
Solution Approach 2:
The system transitions from a single-point reading approach to a multi-dimensional scanning approach by moving the antenna through multiple positions and orientations. This dimensional expansion enables the system to detect all tags throughout the three-dimensional disposed region while preserving reading accuracy through systematic coverage.
2Measurement precision
If wireless tag communication apparatus infers disposed region based on phase difference or machine learning, then tag location can be determined, but inference accuracy is uncertain and may be incorrect
Solution Approach 1:
The system performs inference to determine tag location, then uses the reading device to verify by reading tag data at the inferred position. This feedback loop allows the system to confirm whether the inference was correct and adjust subsequent readings accordingly, thereby improving both inference accuracy and reliability.
Solution Approach 2:
The system performs preliminary inference to identify potential tag locations before conducting comprehensive reading operations. This preliminary action narrows down the search space and guides subsequent reading operations to high-probability areas, improving overall inference accuracy and reliability.
3Ease of operation
If wireless tag communication apparatus does not perform warning processing, then system is simple, but user cannot know whether reading or inference was performed correctly
Solution Approach 1:
The warning device provides feedback to the user by displaying warning information when inference results indicate potential issues such as tags not detected in expected regions or inconsistencies in tag data. This feedback mechanism enhances user awareness of system performance without requiring complex user interaction, balancing ease of operation with appropriate system complexity.
