Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If actual object measurements are performed for each combination of material and surface shape, then measurement precision is improved, but device complexity and time consumption increase significantly
Solution Approach 1:
The patent creates virtual copies of surface shapes (grain patterns, secondary grain patterns) through shape data representation, and virtual copies of material properties through optical characteristic data. These digital models replace the need for physical measurement of every possible combination, allowing reflection characteristics to be estimated through computation rather than physical measurement.
Solution Approach 2:
The patent performs preliminary actions by pre-storing shape data of various grain patterns and optical characteristics of various materials in databases. When a specific combination is needed, the system retrieves pre-stored data and combines it with shape data generation, rather than performing complete measurements from scratch for each combination.
2Reliability
If actual object measurements are performed for each combination of material and surface shape, then reliability of reflection characteristics data is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary actions by pre-acquiring and storing optical characteristics data for various materials and shape data for various grain patterns in databases. This preliminary preparation allows rapid retrieval and combination when specific combinations are needed, significantly reducing the time required compared to performing complete measurements for each combination.
Solution Approach 2:
The patent segments the reflection characteristics determination process into independent components: shape data (grain patterns, secondary grain patterns) and optical characteristics data (material properties). These segmented components can be independently retrieved from databases and combined through computation, eliminating the need for time-consuming complete measurements for each combination.
3Measurement precision
If measurements are performed for specific combinations of grain, secondary grain, and material, then measurement precision is improved, but ease of manufacture worsens
Solution Approach 1:
The patent uses digital copies (shape data and optical characteristics data) to represent physical properties. These digital models can be easily manipulated, combined, and retrieved without the complexity of physical sample preparation and measurement, greatly simplifying the process while maintaining measurement precision through accurate computational modeling.
Solution Approach 2:
The system creates a universal database structure that stores fundamental shape data and optical characteristics data that can be universally applied across multiple combinations. A single shape data set can be combined with multiple material optical characteristics, and vice versa, making the system versatile and easy to use for determining reflection characteristics of any combination.
4Adaptability or versatility
If complete measurements are performed for all possible combinations, then adaptability is improved, but productivity decreases
Solution Approach 1:
The patent segments reflection characteristics into independent shape data components (grain patterns, secondary grain patterns) and material optical characteristics. This segmentation allows the system to handle any combination by simply retrieving and combining the relevant segmented data from databases, providing unlimited adaptability without the productivity penalty of pre-measuring all possible combinations.
Solution Approach 2:
The database structure stores universal shape data and optical characteristics data that can serve multiple purposes and be combined in various ways. A single stored shape data set can be used with multiple material optical characteristics, and a single optical characteristics data set can be applied to multiple grain patterns, enabling the system to adapt to any combination rapidly.
