Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual expertise and trial series are used to determine optimal parameters, then operator-specific knowledge can be applied, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent creates a digital copy of the complex parameter optimization process by storing successful parameter combinations and their outcomes in a database. This digital repository captures the essence of multiple trial series and expert knowledge, allowing rapid retrieval and reproduction of optimal settings without repeating time-consuming physical trials.
Solution Approach 2:
The patent performs preliminary parameter optimization work in advance by conducting trial series and storing the results in a database before actual production. This pre-computed knowledge base enables quick configuration of optimal parameters when production requirements change, eliminating the need for time-consuming real-time optimization.
2Manufacturing precision
If extensive trial series are conducted to find optimal parameter combinations, then reliable tablet quality can be achieved, but the process becomes resource-intensive and difficult to reproduce
Solution Approach 1:
The patent uses a database to store and reuse successful parameter combinations from previous trials. This digital copying approach eliminates the need to physically test the same parameter combinations multiple times, reducing powder material consumption while maintaining the ability to achieve consistent tablet quality through proven settings.
Solution Approach 2:
The patent implements a feedback mechanism where trial results are stored and used to guide future parameter selections. This systematic feedback loop allows the process to learn from previous experiments, avoiding redundant material consumption while continuously improving tablet quality consistency through data-driven decision making.
3Adaptability or versatility
If multiple parameters are adjusted to maintain tablet quality, then adaptability to different powder materials is improved, but the complexity of process configuration increases
Solution Approach 1:
The patent creates a universal database system that stores parameter combinations applicable to different powder materials and tablet requirements. This multi-functional repository can serve various production scenarios by retrieving appropriate pre-stored parameter sets, enabling the system to adapt to different materials without requiring complex real-time calculations or adjustments.
Solution Approach 2:
The patent systematically varies and stores multiple parameter combinations in the database corresponding to different powder material properties and desired tablet characteristics. This pre-computed parameter library allows rapid adaptation to different materials by selecting appropriate stored configurations, avoiding the complexity of manually optimizing multiple parameters for each new material.
4Measurement precision
If statistical design of experiments is used to optimize parameters, then comprehensive parameter coverage is achieved, but time constraints make it infeasible
Solution Approach 1:
The patent performs comprehensive parameter optimization experiments in advance and stores the results in a database. This preliminary action captures the benefits of statistical design of experiments without the time penalty during actual production, as the optimization work is completed beforehand and results are readily available for retrieval.
Solution Approach 2:
The patent creates a digital copy of comprehensive experimental results in a structured database format. This digital repository preserves the thoroughness of statistical experiments while enabling rapid access to optimized parameters, eliminating the need to repeat time-consuming experimental designs during production configuration.
