Engineering Contradiction Analysis
1Shape
If conventional metal effect pigments with traditional shapes are used, then the production process is simple, but the metal pigment effect appearance is suboptimal
Solution Approach 1:
The patent changes the geometric parameters of metal effect pigments from conventional shapes to specific three-dimensional shapes (cubes, pyramids, tetrahedrons) with controlled edge lengths of 20-200 μm. This parameter change creates enhanced light interaction and improved metal pigment effect appearance while maintaining manufacturability through established processes like cold forming, solid forming, casting, and machining.
Solution Approach 2:
The patent applies composite material structures by combining metal effect pigments with base materials in specific compositions. The metal effect pigments are provided with surface coatings and integrated into base materials through controlled composition ratios, creating a composite system that enhances the overall metal pigment effect while allowing optimization of individual component properties.
2Volume of moving object
If metal effect pigments with minimized volume are produced, then the material usage is efficient, but the manufacturing precision requirements increase
Solution Approach 1:
The patent segments the metal effect pigment production into distinct geometric forms (cubes, pyramids, tetrahedrons) with standardized edge length parameters of 20-200 μm. This segmentation allows for controlled volume minimization while maintaining manufacturability through specialized processes. Each geometric form is produced with precision control over its defining parameters, balancing volume efficiency with manufacturing capability.
Solution Approach 2:
The patent replaces conventional mechanical pigment production methods with advanced manufacturing techniques including cold forming, solid forming, casting, and machining processes. These substituted mechanical systems enable precise control over the three-dimensional shapes and volumes of metal effect pigments, achieving minimized volumes while maintaining manufacturing precision through process optimization rather than relying solely on traditional mechanical methods.
