Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robotic systems are used for nasotracheal intubation, then the risk of cross-infection is reduced and operational burden is lessened, but the systems are complex and bulky, making them difficult to carry and transport
Solution Approach 1:
The robotic system is divided into multiple independent modules: a robotic arm module for positioning, an endoscope module for imaging, a control module for processing images and generating control signals, and a catheter module for delivery. This segmentation allows each module to be optimized independently and facilitates easier transport and deployment in clinical settings.
Solution Approach 2:
The robotic system integrates multiple functions into a single platform: it performs anatomical feature detection, real-time image processing, robotic arm control, and catheter delivery. This multi-functionality reduces the need for separate devices and simplifies the overall system configuration while maintaining comprehensive intubation capabilities.
2Ease of operation
If robotic systems for nasotracheal intubation are developed, then doctor burden is reduced, but there is little study on robotic nasotracheal intubation and existing systems rely heavily on experienced doctors for operation
Solution Approach 1:
The system incorporates automatic anatomical feature detection that independently identifies the nasal cavity, throat, and glottis without requiring manual guidance from experienced doctors. The image processing algorithm automatically segments and recognizes key anatomical structures, enabling the robotic system to perform complex navigation tasks autonomously and reducing reliance on operator expertise.
Solution Approach 2:
The system uses real-time image feedback from the endoscope to continuously update the robotic arm's position and adjust the catheter delivery path. The control module processes incoming images, compares them with anatomical templates, and generates corrective control signals to maintain accurate positioning, creating a closed-loop control system that enhances precision without increasing operational complexity.
3Ease of operation
If existing robot systems are used, then remote operation is possible, but the systems lack the ability to autonomously identify key anatomical characteristics, increasing the cognitive burden of doctors
Solution Approach 1:
The system performs preliminary image processing and anatomical feature detection before the actual catheter delivery. The control module pre-identifies key anatomical landmarks and plans the optimal delivery path in advance, allowing the robotic system to execute the intubation procedure with minimal real-time intervention and reducing the cognitive load on remote operators.
Solution Approach 2:
The system replaces manual anatomical identification with an automated image processing algorithm that uses computer vision techniques to detect and segment anatomical structures. This substitution of mechanical/visual inspection with algorithmic analysis enables autonomous recognition of anatomical features, preserving critical information that would otherwise require expert interpretation and reducing the cognitive burden on doctors.
