Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hand-held reading devices are used for component detection, then data acquisition accuracy is improved, but processing time increases and productivity decreases
Solution Approach 1:
The patent combines multiple functions (barcode reading, RFID reading, data processing, and display) into a single integrated wearable device that is worn on the worker's body. This merging eliminates the need to separately handle multiple devices while maintaining all necessary detection capabilities, thereby improving both accuracy and processing speed.
Solution Approach 2:
The wearable device automatically detects components and processes data without requiring manual operation. The device performs self-service by automatically scanning barcodes, reading RFID tags, processing the detected data, and providing feedback, which eliminates the time-consuming manual steps of taking devices in and out, manually scanning, and recording data.
2Difficulty of detecting and measuring
If hand-held reading devices are used for component detection, then detection capability is improved, but operation complexity increases
Solution Approach 1:
The wearable device automatically performs detection without requiring manual operation. It self-activates when approaching a component, automatically scans barcodes, reads RFID tags, processes the data, and provides feedback. This eliminates the need for workers to learn and execute complex manual operations while maintaining advanced detection capabilities.
Solution Approach 2:
The device merges multiple detection functions (barcode scanning, RFID reading, data processing, and feedback display) into a single integrated unit that is always accessible on the worker's body. This consolidation simplifies operation by eliminating the need to switch between multiple devices or perform sequential manual steps.
3Measurement precision
If manual handling of reading devices is required, then detection accuracy is maintained, but time expenditure increases
Solution Approach 1:
The wearable device performs all detection and processing operations automatically without requiring manual handling. It continuously monitors the environment, automatically triggers scans when components are detected, processes the data in real-time, and provides immediate feedback. This eliminates the time spent on manually taking devices in and out, positioning them for scanning, and recording results, while maintaining detection accuracy through the same sensor technologies.
