Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between the material platform and printing head, then structural stability is improved, but flexibility and printing precision deteriorate due to twisting effects of wire feeding pipes
Solution Approach 1:
The system divides the connection into two independent rotational segments: the platform frame rotates around a second axis relative to the base frame, and the nozzle seat rotates around a first axis relative to the printing seat. This segmentation allows each component to rotate independently without causing twisting effects on wire feeding pipes, thereby maintaining flexibility while preserving structural stability.
Solution Approach 2:
The patent introduces dynamic rotational capabilities to both the platform frame and nozzle seat, transforming a static rigid connection into a dynamic system. The platform frame can rotate to accommodate material feeding requirements, and the nozzle seat can rotate to position non-circular nozzles correctly, enabling the system to adapt dynamically during printing operations without structural distortion.
2Productivity
If multiple nozzles are arranged on the printing head, then simultaneous printing capability is improved, but device complexity increases due to rotation restrictions from wire feeding pipes
Solution Approach 1:
The patent segments the multi-nozzle system into independent rotational units. Each nozzle group on the nozzle seat can rotate around the first axis independently, allowing multiple nozzles to be positioned and operated simultaneously without being constrained by wire feeding pipe twisting. This segmentation enables complex multi-nozzle configurations while maintaining operational simplicity.
Solution Approach 2:
The dynamic rotation of the nozzle seat around the first axis enables multiple nozzles to be dynamically positioned in different orientations during printing. This dynamic capability allows the system to handle complex multi-nozzle printing tasks without increasing device complexity, as the rotation mechanism provides a unified solution for positioning all nozzles.
3Manufacturing precision
If a non-circular nozzle is used, then printing precision for specific geometries is improved, but adaptability deteriorates due to difficulty in maintaining correct orientation during movement
Solution Approach 1:
The nozzle seat's rotation around the first axis provides dynamic orientation control for non-circular nozzles. During printing operations, the nozzle seat can rotate to maintain the correct orientation of the non-circular nozzle relative to the printing path, ensuring high printing precision for specific geometries while adapting to different movement directions and printing requirements.
Solution Approach 2:
The rotatable nozzle seat design provides universal adaptability for different nozzle types and orientations. The same rotational mechanism can accommodate non-circular nozzles for high-precision printing, circular nozzles for general purposes, and multiple nozzles for complex geometries, making the system universally applicable to various printing requirements without sacrificing adaptability.

AI summary
A 3D printing system includes a printing head, a base frame and a material platform. The printing head includes a printing seat and a nozzle seat, where the nozzle seat may rotate relative to the printing seat, and an extrusion opening is formed in the nozzle seat. The material platform includes a frame which may rotate relative to the base frame, and at least one feeding component. The feeding component includes a rotatable follow-up portion arranged on the frame, and the feeding component is used for conveying printing materials to the extrusion opening. A flexible line is connected between the frame and the nozzle seat, and includes a conveying line formed between the feeding component and the extrusion opening for conveying printing materials. The platform frame may rotate following the nozzle seat to prevent excessive winding of the flexible line.
