Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional simulated physiological structures are constructed from durable plastics and rubbers, then durability and ease of manufacturing are improved, but anatomical fidelity and realism deteriorate
Solution Approach 1:
The patent applies composite materials by combining silicone rubber (for anatomical realism) with internal plastic skeletons and support structures (for durability). The silicone materials replicate human tissue properties while the internal framework provides structural integrity, resolving the contradiction between realism and durability.
Solution Approach 2:
The simulated physiological structure is divided into modular segments (head, torso, limbs, organs) that can be independently manufactured with high anatomical fidelity using silicone, while connection points and internal frameworks use durable plastics. This segmentation allows each component to be optimized for its specific function.
2Ease of manufacture
If conventional simulated physiological structures are designed as single-unit systems, then ease of manufacture is improved, but adaptability for different training scenarios deteriorates
Solution Approach 1:
The system is segmented into modular components (different organ systems, anatomical regions, pathological conditions) that can be independently manufactured and then assembled in various combinations. This allows a single manufacturing process to produce multiple training scenarios by reconfiguring the modular elements.
Solution Approach 2:
The modular components are designed with universal connection interfaces and standardized mounting mechanisms, allowing the same basic components to serve multiple training purposes. For example, the same torso module can be configured for different surgical procedures or trauma scenarios by changing the internal organ arrangements.
3Ease of operation
If conventional simulated physiological structures lack tactile realism, then ease of operation is improved, but training effectiveness deteriorates due to negative training
Solution Approach 1:
The patent changes the physical parameters of the simulation materials to match human tissue properties, including viscosity, elasticity, temperature, and texture. The silicone materials are formulated to replicate the tactile feedback of real human organs, providing realistic resistance and compliance during medical procedures while maintaining ease of manipulation.
4Device complexity
If conventional simulated physiological structures do not include sensor integration, then device complexity is reduced, but objective performance evaluation capability deteriorates
Solution Approach 1:
The patent replaces subjective visual assessment with objective sensor-based measurement systems. Force sensors, pressure sensors, and displacement sensors are integrated into the simulated structures to automatically detect and quantify student performance metrics, replacing the need for complex manual evaluation procedures.
