Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surgical tools are made more powerful and versatile to improve surgical capabilities, then surgical effectiveness is improved, but the risk of injury to the patient increases due to erroneous handling
Solution Approach 1:
The system continuously captures video feeds from cameras during surgery, processes them through machine learning models to detect surgical tools and anatomical structures, and provides real-time feedback by enabling or disabling tool functions based on detected conditions. This closed-loop feedback mechanism ensures that powerful surgical tools only operate when proper anatomical targets are confirmed, reducing injury risk while maintaining full functionality when appropriate.
Solution Approach 2:
The computer vision system acts as an intermediary between the surgeon and the surgical tools. Rather than directly controlling tools, the system processes visual information and translates it into control signals that enable or disable tool functions. This intermediary layer adds a safety checkpoint that prevents erroneous handling while preserving surgical versatility.
2Reliability
If computer-vision systems are implemented to improve surgical safety through real-time monitoring, then patient safety is improved, but system complexity increases
Solution Approach 1:
The system uses multi-functional components where cameras serve both as surgical documentation devices and as sensors for the computer vision safety system. The machine learning models perform multiple tasks including tool detection, anatomical structure identification, and surgical phase recognition. This multi-functionality reduces overall system complexity by consolidating capabilities into existing components.
Solution Approach 2:
The machine learning models are pre-trained on extensive surgical datasets, enabling them to automatically recognize tools and anatomical structures without requiring real-time human annotation or complex rule-based programming. The system self-configures by learning from training data, reducing the complexity of implementing real-time monitoring capabilities.
3Measurement precision
If machine-learning models are trained to recognize surgical tools and anatomical structures with high precision, then detection accuracy is improved, but training time and computational resources increase
Solution Approach 1:
Machine learning models are trained offline on extensive datasets of surgical images and videos before deployment. This preliminary training action creates pre-trained models that can be rapidly deployed without requiring real-time training during surgeries. The heavy computational lifting is performed in advance, allowing high precision recognition during actual surgical procedures with minimal delay.
Solution Approach 2:
The system uses multiple machine learning models with different levels of complexity for different detection tasks. Simpler models handle straightforward tool recognition, while more complex models are used for challenging anatomical structure identification. This partial application of computational resources optimizes the balance between training time and detection accuracy.
