Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional greenware materials are used, then the manufacturing process is simple, but the ceramic products cannot maintain complex or distinctive shapes with high design quality
Solution Approach 1:
The feldspar is divided into two distinct particle size fractions: first feldspar (5.0-20.0 µm) and second feldspar (2.0-4.0 µm). This segmentation allows each fraction to perform specific functions - the coarser particles provide structural framework while the finer particles fill gaps and reduce deformation, enabling complex shapes to be achieved without excessive material complexity
Solution Approach 2:
Different regions of the greenware material have different particle size compositions. The plastic raw material (0.5-6.0 µm) is combined with two different feldspar fractions to create localized zones with optimized properties for specific functional requirements, allowing the material to achieve high shape accuracy while maintaining manageable composition complexity
2Stability of the object's composition
If conventional greenware materials are used, then the material composition is simple, but deformation occurs during molding and firing
Solution Approach 1:
The invention changes the particle size parameters of the raw materials, specifically controlling the average particle size of plastic raw material (0.5-6.0 µm) and dividing feldspar into two size ranges (5.0-20.0 µm and 2.0-4.0 µm). This parameter optimization stabilizes the material composition during molding and firing, preventing deformation while avoiding the complexity of multiple raw material groups
3Use of energy by moving object
If conventional greenware materials are used, then high firing temperatures are required, but energy efficiency is reduced
Solution Approach 1:
By optimizing the particle size parameters of the raw materials - specifically using plastic raw material (0.5-6.0 µm) combined with two feldspar fractions - the firing temperature can be reduced while maintaining material performance reliability. The finer particle sizes improve heat distribution and reduce the energy required for firing
