Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate barcode readers or RFID units are used to recognize code information, then code recognition accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the code recognition function and reaction result photographing function into a single camera device. The camera captures both the code information and the reaction result in one shot, eliminating the need for separate barcode readers or RFID units. This merging approach maintains code recognition capability while significantly reducing device complexity and cost.
Solution Approach 2:
The camera is designed to perform multiple functions: recognizing code information, photographing reaction results, and providing positioning information. This multi-functional approach allows a single device to replace what would traditionally require multiple specialized devices, thereby reducing overall system complexity while maintaining measurement precision.
2Reliability
If separate barcode readers are used to read codes, then code reading reliability is improved, but analysis time increases due to additional operations
Solution Approach 1:
The camera simultaneously captures code information and reaction results in a single operation, eliminating the sequential process of first reading codes with a barcode reader and then photographing results. This parallel capture approach maintains reliable code recognition while significantly reducing the total analysis time.
Solution Approach 2:
The system performs preliminary image processing to automatically separate and identify code regions from reaction result regions in the captured image. This preliminary processing enables the system to extract code information reliably without requiring manual intervention or additional reading operations, thereby reducing analysis time.
3Measurement precision
If additional equipment is used for code recognition, then measurement accuracy is improved, but miniaturization becomes difficult
Solution Approach 1:
The patent integrates code recognition and reaction result capture functions into a single camera module, eliminating the need for additional separate equipment. This integration maintains measurement accuracy through reliable code recognition while enabling device miniaturization by removing extra hardware components that would increase overall device volume.
