Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additive processing is performed without fiducial reference, then processing can be performed quickly, but positioning accuracy of energy beam deteriorates
Solution Approach 1:
A fiducial build object is formed in advance on the support apparatus before actual additive processing begins. This fiducial object serves as a reference marker that enables accurate positioning and alignment of the energy beam during subsequent processing operations, eliminating the need for complex real-time positioning systems.
Solution Approach 2:
The system creates a simplified fiducial build object that copies only the essential positioning features needed for alignment, rather than processing the complete target object. This fiducial copy provides sufficient reference information for accurate energy beam positioning while keeping the reference object simple and easy to measure.
2Manufacturing precision
If fiducial build object is formed and measured, then positioning accuracy improves, but processing time increases
Solution Approach 1:
Instead of measuring or processing the entire target object with high precision, the system applies high precision only to the localized fiducial build object. This fiducial object contains only the critical positioning information needed for energy beam alignment, allowing rapid measurement and positioning while maintaining high accuracy where it matters most.
Solution Approach 2:
The system performs partial processing by forming only a fiducial build object rather than the complete target object during the positioning phase. This partial action provides sufficient reference information for accurate positioning without the time cost of forming or measuring the entire target structure, enabling faster setup while maintaining positioning accuracy.
