Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional alignment method is used, then the alignment process is simple, but the alignment speed and accuracy are insufficient
Solution Approach 1:
The alignment module is divided into multiple independent alignment portions (first alignment portion, second alignment portion, third alignment portion), each responsible for aligning the head in different directions. Each portion has its own operating portions and connection members, allowing independent adjustment and improving overall alignment accuracy without requiring a single complex alignment mechanism.
Solution Approach 2:
The alignment system transitions from single-direction alignment to multi-dimensional alignment by adding alignment portions that operate in different directions (first direction, second direction, third direction). This dimensional expansion enables comprehensive alignment of the head in three-dimensional space, significantly improving alignment accuracy and adaptability.
2Manufacturing precision
If multiple alignment portions are added, then alignment accuracy improves, but alignment time increases
Solution Approach 1:
The connection members are pre-configured with attractive forces that automatically pull the alignment portions toward each other during the alignment process. This preliminary setup of attractive forces enables the alignment portions to self-adjust and converge on the correct positions without requiring time-consuming manual adjustments or sequential alignment steps, thereby reducing overall alignment time while maintaining high accuracy.
Solution Approach 2:
The alignment portions are equipped with self-aligning capabilities through the attractive forces from connection members and the coordinated operation of multiple operating portions. The system performs self-adjustment and self-correction during the alignment process, eliminating the need for external intervention or sequential manual alignment operations, thus reducing alignment time while ensuring precision.
3Stability of the object's composition
If connection members with attractive forces are used, then alignment stability improves, but device complexity increases
Solution Approach 1:
Multiple connection members with attractive forces are integrated into a unified alignment module structure, combining their stabilizing effects to maintain the relative positions of alignment portions. This merging of connection functions into a cohesive system provides enhanced alignment stability while distributing the complexity across multiple standardized components rather than requiring a single complex stabilization mechanism.
