Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional simulators are used for heart disease operations, then general catheter manipulation skills can be improved, but specific maneuvers for leadless pacemaker installation cannot be trained
Solution Approach 1:
The patent creates a simplified copy of the heart structure (heart model) that replicates the essential anatomical features needed for leadless pacemaker installation training. The model includes a ventricle cavity, interventricular septum, and simulated blood vessel passages that mirror real human anatomy, allowing trainees to practice catheter manipulation and pacemaker deployment in a safe environment before performing actual procedures on patients.
Solution Approach 2:
The patent modifies physical parameters of the training system by using materials with specific elasticities and textures that simulate real heart tissue properties. The heart model is made from elastic material that can be punctured and penetrated by catheters similarly to actual heart tissue, providing realistic tactile feedback for training purposes while eliminating the risks associated with real patient procedures.
2Ease of operation
If a heart model with realistic tissue properties is used, then training realism is improved, but the model becomes more complex and harder to manufacture
Solution Approach 1:
The patent divides the heart model into distinct functional segments: the ventricle cavity, the interventricular septum with holder, and the simulated blood vessel passages. This segmentation allows each component to be optimized independently for its specific function while simplifying the overall manufacturing process. The holder component is further segmented to allow detachable assembly, facilitating easier manufacturing and assembly.
Solution Approach 2:
The patent applies different material properties and structural characteristics to different regions of the heart model based on local functional requirements. The ventricle cavity wall is made from elastic material to simulate real heart tissue for catheter penetration training, while the interventricular septum region includes a specialized holder structure with opening for pacemaker deployment. This localized differentiation provides realistic training experiences without requiring the entire model to be overly complex.
3Stability of the object's composition
If the holder is permanently installed in the heart model, then structural stability is improved, but the model cannot be reused for multiple training sessions
Solution Approach 1:
The patent designs the holder as a dynamic component that can be detached and reattached to the interventricular septum. The holder includes an opening that allows it to be installed in a specific position to simulate the interventricular septum structure, and can be removed and reinstalled multiple times. This dynamic design enables the heart model to be reused for multiple training sessions while maintaining structural stability during each training exercise.
