Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection is performed by inspection technicians, then defect detection can be conducted, but human error leads to high error rates in defect detection
Solution Approach 1:
The patent replaces the mechanical visual inspection system performed by technicians with an automated optical inspection system using machine learning algorithms. The system captures images of the medical device interior and uses trained machine learning models to automatically identify defects, eliminating human error and providing consistent, reliable defect detection across all inspections.
Solution Approach 2:
The inspection system performs self-diagnosis by automatically analyzing images and identifying defects without requiring human interpretation. The machine learning model independently evaluates the captured images, determines the presence and type of defects, and generates inspection results, making the system self-sufficient and eliminating variability in human judgment.
2Measurement precision
If automated detection systems are implemented, then defect detection accuracy is enhanced, but system complexity increases
Solution Approach 1:
The patent designs a universal inspection system that can detect multiple types of defects (biological, mechanical, non-biological) across different medical device types using a single machine learning framework. The system is configured to identify various defect categories including bio-burden, cracks, breaks, and foreign objects, making it versatile and reducing the need for multiple specialized inspection systems.
Solution Approach 2:
The patent introduces an image processing intermediary layer that captures visual data and translates it into structured defect information. The machine learning model acts as an intermediary between the raw image data and the final inspection conclusion, automatically processing images to identify and categorize defects, thereby simplifying the overall system architecture while maintaining high detection accuracy.
3Measurement precision
If thorough visual inspection is performed, then defect detection improves, but inspection time increases reducing productivity
Solution Approach 1:
The patent implements continuous automated inspection where the machine learning system processes images in real-time as they are captured, eliminating the intermittent human review process. The system continuously analyzes defect patterns, provides immediate feedback on defect presence, and maintains constant inspection throughput, thereby improving both accuracy and productivity simultaneously.
Solution Approach 2:
The patent applies preliminary action by pre-training machine learning models on extensive defect datasets before deployment. The models are预先 trained to recognize various defect types and patterns, enabling them to rapidly and accurately classify defects during actual inspections without requiring time-consuming manual analysis, thus maintaining high throughput while ensuring accurate detection.
Data Source
AI summary
Methods and systems identify defects in a medical device and tailor a protocol, namely, further recommended action, for the device based on a combination of the nature of the defects and procedural data including patient data and/or medical instrument record data. Computer-implemented instructions are used to determine the presence and nature of the defects. Artificial intelligence and/or algorithms may be used to implement the computer-implemented instructions, and process image data from a digital camera system. Upon identification of a defect present, the detection system may notify users of the presence of the defect, as well as provide further recommended action to be taken regarding the medical device, reducing potential instrument failure, patient injury or death. The methods and systems may be integrated into existing disinfection and sterilization systems and techniques currently used in medical facilities, such as hospitals and surgery centers.
