Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple 2D images from different patients are aggregated to create 3D models, then the accuracy and realism of surgical simulations is improved, but the device complexity and data processing requirements increase

Engineering Contradiction:
Improve3D model accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple 2D images from different patients into a single aggregated 3D model. The processor receives first 2D image data from a first patient and second 2D image data from a second patient, then generates 3D image data by aggregating these multiple data sources. This merging approach improves the accuracy and realism of the surgical simulation model by incorporating anatomical variations from multiple subjects.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The surgical simulation platform is designed to handle multiple types of input data (2D images from different patients, 3D reconstruction reference data) and perform multiple functions (generating 3D models, mapping deformable surfaces, simulating surgical procedures). The system can process and integrate various data sources to create universally applicable surgical training simulations that represent diverse anatomical structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If deformable 3D models are used to simulate tissue behavior, then the realism of surgical training is improved, but the computational requirements and processing time increase

Engineering Contradiction:
Improvetissue deformation realismVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary processing by receiving and storing 3D reconstruction reference data and tissue property data before the actual surgical simulation occurs. The deformable 3D model is pre-configured with anatomical structures and material properties, so that during the surgical training exercise, the model can respond realistically to surgical interventions without requiring extensive real-time computation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a deformable 3D model that can dynamically change shape and properties in response to simulated surgical forces. The model maps surface deformations based on tissue property data, allowing realistic simulation of how different tissues (e.g., liver, kidney, tumor) respond to cutting, grasping, or other surgical maneuvers. This dynamic behavior enhances training realism while the system optimizes computation to maintain acceptable processing speeds.

Inventive Principle:
Principle #15Dynamics
