Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate bar code reader or RFID unit is used for code recognition, then code reading accuracy is improved, but device complexity increases and miniaturization becomes difficult
Solution Approach 1:
The patent combines the code recognition function with the existing camera unit by equipping the camera with image processing capabilities to read barcodes and RFID tags. This integration eliminates the need for separate code reading devices, reducing overall device complexity while maintaining accurate code recognition through software-based image analysis.
Solution Approach 2:
The camera unit is designed to perform multiple functions: photographing specimen reaction results and recognizing code information on diagnostic kits. By making the camera a multi-functional component, the patent eliminates the need for dedicated separate devices for code reading, thereby simplifying the overall system structure while preserving measurement precision.
2Measurement precision
If a separate bar code reader or RFID unit is used for code recognition, then code reading accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the code recognition function into the existing camera unit, eliminating the need to manufacture and assemble separate code reading devices. This integration reduces component count and assembly complexity, thereby lowering manufacturing costs while maintaining accurate code reading capabilities through enhanced image processing software.
Solution Approach 2:
By designing the camera unit to serve dual purposes (photographing reaction results and reading codes), the patent reduces the total number of components that need to be manufactured and assembled. This multi-functional approach decreases manufacturing complexity and cost while preserving the precision of code recognition.
3Measurement precision
If separate operation for code reading is performed, then code recognition accuracy is improved, but analyzing time is delayed
Solution Approach 1:
The patent performs code recognition simultaneously with the photographing process by capturing both the code information and specimen reaction result in a single imaging operation. This preliminary integration of code reading into the main photographing workflow eliminates sequential processing delays, reducing total analysis time while maintaining recognition accuracy through comprehensive image analysis.
Solution Approach 2:
The camera unit continuously performs both code recognition and reaction result photographing in an uninterrupted single operation. This continuous dual-function operation eliminates the time loss associated with separate sequential operations, maintaining accurate code recognition while significantly reducing the total time required for the analysis process.
4Productivity
If diagnostic kit is inserted into analysis apparatus, then specimen analysis is enabled, but peel-off phenomenon occurs causing analysis errors
Solution Approach 1:
The patent replaces mechanical code reading mechanisms with optical/image-based recognition using a camera unit. This substitution eliminates the mechanical insertion and contact processes that cause peel-off phenomena, allowing non-contact photographing of both code information and specimen reaction results, thereby maintaining analysis capability while improving reliability.
