Solution Overview
Problem
Current 3D scanning and digitization techniques do not effectively simulate the deformation of objects when forces are applied, limiting the ability to visualize and model how objects change shape or move under various conditions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If forces are applied to objects during scanning to capture deformation, then the ability to simulate deformation is improved, but the complexity of the scanning system increases
Solution Approach 1:
The system applies forces to the object during the scanning process itself, capturing deformation states in advance. This allows the 3D data model to incorporate deformation information directly from the scanning phase, eliminating the need for separate deformation capture equipment or post-processing physical deformation tests.
Solution Approach 2:
The scanning system is enhanced to serve multiple functions: it not only captures the static 3D geometry of the object but also captures deformation states when forces are applied. This multi-functional approach allows a single system to perform both standard scanning and deformation capture without requiring entirely separate apparatus.
2Measurement precision
If multiple reference scans are captured during deformation to improve simulation accuracy, then the precision of deformation modeling is improved, but the time required for scanning increases
Solution Approach 1:
The system captures multiple reference scans continuously during the application of forces, maintaining continuous measurement of the object's deformation state. This continuous scanning approach ensures that deformation information is captured across multiple force applications and time points without interruption, improving model precision while minimizing idle time.
Solution Approach 2:
The scanning system performs periodic captures of reference scans at intervals during the deformation process. This periodic sampling of the object's state under varying forces allows the system to build a comprehensive deformation model through multiple measurements taken at different moments, balancing precision requirements with scanning time efficiency.

AI summary
Disclosed are methods and systems for determining and displaying a simulated deformation of a 3D object data model. In one aspect, a method is disclosed that includes causing a force to be applied to an object to cause a deformation of the object and causing a plurality of reference scans of the object to be captured. The method further includes, based on the plurality of reference scans, generating a 3D object data model representing the object and, further based on the plurality of reference scans, identifying a constraint point of the 3D object data model, where the constraint point represents a point of minimum deformation of the object. The method still further includes selecting a predefined deformation model, where the predefined deformation model defines a simulated deformation, and where the simulated deformation simulates at least a portion of the deformation of the object proximate to the point of minimum deformation.
