Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed or rigid tracks are used in 3D printing, then the printing process is stable and controlled, but the ability to print large objects or modify existing objects with intricate geometries is restricted
Solution Approach 1:
The patent applies the dynamics principle by transforming the static, fixed track system into a dynamic, reconfigurable one. The snake robot segments can independently move and position themselves to create different track configurations, enabling the system to adapt to various object geometries and printing requirements while maintaining structural support during the printing process
Solution Approach 2:
The patent applies segmentation by dividing the continuous track into multiple independent snake robot segments. Each segment can be controlled separately to form different shapes and configurations, allowing the track system to accommodate complex profiles and modify existing objects with intricate geometries that would be impossible with a rigid fixed track
2Manufacturing precision
If fixed tracks are used, then the printing process is simple to control, but complex shapes and geometries cannot be achieved
Solution Approach 1:
The patent applies feedback by implementing control systems that monitor the positions and configurations of the snake robot segments, allowing real-time adjustments to maintain precision when creating complex geometries. The system can detect deviations and automatically correct them, ensuring manufacturing precision while managing control complexity through automated feedback loops
3Volume of moving object
If configurable movement tracks are implemented, then complex shapes and large objects can be printed, but the system complexity increases
Solution Approach 1:
The patent applies universality by designing the snake robot track system to perform multiple functions: providing structural support, defining movement paths, and adapting to various object sizes and geometries. This multi-functional design allows a single configurable system to handle diverse printing tasks including large objects and complex shapes without requiring multiple specialized systems
Solution Approach 2:
The dynamic nature of the snake robot segments allows the system to scale and reconfigure for different object volumes. The segments can extend, contract, and reposition to accommodate large objects while maintaining the necessary precision and support, effectively managing system complexity through adaptive dynamics

AI summary
Embodiments of the invention are directed to a computer-implemented method that includes receiving, using a processor, data representing a 3D physical object by a processing device, and controlling, using the processor, a 3D printing device to apply successive layers of a material by a printing head including a nozzle. The controlling includes depositing at least one layer by instructing a snake robot of a configurable track system to form a shape and define a movement track that corresponds to a movement profile aligned with the 3D model, moving the printing head along the movement track defined by the snake robot, and depositing the at least one layer via the nozzle as the printing head is moved along the movement track.
