Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a scalpel is used to incise the submucosa, then the incision can be made, but the incision depth is difficult to control and bleeding occurs
Solution Approach 1:
The patent replaces the mechanical scalpel cutting system with an energy-based RF electrosurgical system. The RF electrode delivers controlled energy through the mucosa to the submucosa, creating a cutting effect without mechanical contact, thereby achieving precise depth control and minimizing bleeding through coagulation.
Solution Approach 2:
The patent changes the physical state and parameters of energy delivery by using RF electromagnetic energy with specific impedance matching and controlled power delivery. The system monitors and adjusts energy parameters to achieve precise thermal effects in the submucosa while sparing deeper tissues, enabling controlled incision depth and reduced bleeding.
2Reliability
If RF energy is applied to treat the submucosa, then the submucosa can be treated, but excessive energy may damage surrounding healthy tissue
Solution Approach 1:
The patent applies RF energy locally and selectively to the submucosa through a positioned electrode. The energy delivery is concentrated at the treatment site with controlled spatial distribution, allowing effective submucosal treatment while limiting thermal spread to surrounding healthy tissues through precise electrode positioning and controlled energy parameters.
Solution Approach 2:
The patent incorporates impedance sensing and temperature monitoring feedback mechanisms that detect tissue conditions in real-time. The system automatically adjusts energy delivery based on feedback signals, reducing energy input when adequate treatment effect is achieved or when approaching safe thermal limits, thereby preventing damage to surrounding healthy tissue while ensuring effective submucosal treatment.
