Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If barcode reading method is used to identify objects, then object information can be read, but it is difficult to read barcodes of several objects simultaneously
Solution Approach 1:
The patent combines multiple sensing technologies (barcode scanning, RFID reading, IR sensing) into a single integrated sensing device. This merging allows the system to simultaneously perform multiple object identification tasks - reading barcodes on visible surfaces while simultaneously detecting RFID tags and IR signatures, thereby increasing productivity without requiring separate devices for each function.
Solution Approach 2:
The integrated sensing device is designed to perform multiple functions: barcode scanning for visual identification, RFID reading for wireless identification, and IR sensing for thermal/temperature-based identification. This multi-functional approach enables the system to handle various object types and identification scenarios simultaneously, resolving the limitation of single-function devices.
2Measurement precision
If RFID tag reading method is used to identify objects, then object types can be determined, but it is difficult to determine types of the objects accurately
Solution Approach 1:
The system merges RFID reading with barcode scanning and IR sensing capabilities in a single integrated device. By combining these three identification methods, the system cross-validates object type information - RFID provides wireless tag data, barcode scanning provides visual confirmation, and IR sensing provides thermal characteristics. This multi-modal approach significantly improves measurement precision for object type determination.
Solution Approach 2:
The system implements feedback mechanisms where the integrated sensing device continuously collects data from multiple sources (RFID, barcode, IR) and uses AI analysis to refine object type determination. The feedback loop allows the system to learn from multiple data streams and improve identification accuracy over time, resolving the limitation of single-method identification.
3Measurement precision
If infrared sensor is used to measure temperature and determine object types, then object types can be identified, but a measured temperature value and the object need to be matched in advance for association
Solution Approach 1:
The integrated sensing device merges IR temperature sensing with RFID reading and barcode scanning in a single unit positioned at the same location. This spatial merging means all three sensors detect data from the same object simultaneously, automatically associating temperature values with corresponding RFID tags and barcode information. The system eliminates the need for manual data association by capturing all data streams from the same physical location at the same time.
Solution Approach 2:
The patent introduces an AI analysis server as an intermediary that automatically processes and associates data from multiple sensing modalities. The AI server receives raw data from RFID tags, barcode scans, and IR temperature measurements, then uses machine learning algorithms to automatically match and correlate this information, eliminating the need for manual pre-matching and simplifying operation.
4Measurement precision
If multiple sensors are used to acquire RFID tag and IR image data, then object identification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple sensing technologies (RFID readers, IR cameras, barcode scanners) into a single integrated sensing device with unified control and data processing. This physical and functional merging reduces the complexity that would arise from coordinating multiple separate devices, while still achieving improved measurement precision through multi-modal data collection.
