Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If layer-by-layer construction method is used, then manufacturing precision is maintained, but construction time increases significantly
Solution Approach 1:
The patent transitions from static layer-by-layer deposition to dynamic material scattering. The scattering device projects material particles in controlled trajectories to build three-dimensional structures, allowing simultaneous multi-point material placement rather than sequential layer deposition, thereby reducing construction time while maintaining precision through controlled particle trajectories
Solution Approach 2:
The patent replaces the mechanical layer-by-layer deposition system with a material scattering system that uses controlled particle projection. Instead of physically placing material layers sequentially, the system scatters material particles along controlled paths to achieve three-dimensional structure formation, significantly improving construction speed
2Adaptability or versatility
If traditional additive manufacturing is used, then complex geometries can be created, but repair of defects is difficult without damaging the object
Solution Approach 1:
The scattering device enables localized material deposition by controlling the scattering angles and trajectories of material particles. This allows precise targeting of specific defect areas or complex geometry regions without affecting other parts of the object, facilitating easy repair while maintaining the ability to create complex geometries
Solution Approach 2:
The dynamic control of material scattering trajectories allows the system to adapt to different repair scenarios and complex geometry requirements in real-time, enabling both complex geometry creation and defect repair through the same flexible mechanism
