Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual CFU counting methods are used, then data collection speed is low and errors occur, but the system complexity remains simple
Solution Approach 1:
The patent replaces manual mechanical counting processes with automated deep learning-based image analysis systems. Multiple pre-trained deep learning models process captured images to automatically identify and count CFUs, eliminating manual intervention and significantly increasing data collection speed while maintaining high accuracy through model comparison and validation mechanisms
Solution Approach 2:
The patent uses multiple pre-trained deep learning models as parallel processing copies to analyze the same image data. By running several models simultaneously and comparing their results, the system achieves higher reliability and accuracy in CFU counting while automating the process, thus improving productivity without proportionally increasing system complexity
2Measurement precision
If multiple deep learning models are used for CFU counting, then accuracy and integrity improve, but processing time increases
Solution Approach 1:
The patent applies preliminary action by using pre-trained deep learning models that have already been trained on extensive datasets before deployment. This allows the models to quickly process images without requiring training time during actual CFU counting operations. The pre-training ensures high accuracy while the efficient inference engines minimize processing time during actual use
Solution Approach 2:
The patent implements feedback mechanisms by comparing results from multiple deep learning models and using validation processes. When model outputs are consistent, the system quickly accepts the result; when there are discrepancies, the system efficiently resolves them through predefined validation rules or selective re-processing, thus maintaining high accuracy while minimizing overall processing time through intelligent feedback loops
3Reliability
If automated data documentation is implemented, then data integrity improves, but device complexity increases
Solution Approach 1:
The patent applies self-service by implementing automated systems that perform data documentation without human intervention. The deep learning models automatically extract CFU counting results, validate the data, and document findings in standardized formats. This self-documenting capability ensures data integrity through consistent automated processes while the modular architecture keeps system complexity manageable through reusable components

AI summary
This application relates to a method for processing image data of a microbial culture medium to recognize colony forming unit (CFU). In one aspect, the method includes receiving, at a processor, captured image data of the microbial culture medium from a user device, and preprocessing, at the processor, the captured image data. The method may also include counting, at the processor, the number of CFUs included in the preprocessed image data to derive result data including the counted number of CFUs. The method may further include automatically inputting information included in the result data into a predetermined template to generate document data corresponding to the captured image data, and transmitting at least one of the result data or the document data to the user device.
