Solution Overview
Problem
Conventional batch methods for producing tablets, such as pharmaceutical products, face challenges in continuous processing, requiring extensive material usage, high costs, and difficulty in timely monitoring of mixing degrees, leading to inconsistent product quality and inefficiencies in scaling up production.
Innovation Solution
A system that continuously monitors the mixing degree of powdery materials using sensors and adjusts the feed rate and mixing speed to maintain a predetermined mixing range, ensuring consistent quality and optimizing the production process by integrating measuring feeders and mixers with a control system to adjust the flow rate and rotational speed of the compression molding machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If batch method is used for tablet production, then each process can be conducted separately with individual facility design, but standby periods occur between processes and large space is required
Solution Approach 1:
The patent implements continuous processing where granulating, drying, grading, mixing, and compression molding are conducted without standby periods between processes. Intermediate products are continuously fed from one process to the next, eliminating idle time and maintaining continuous operational flow throughout the production line.
Solution Approach 2:
The patent combines multiple separate batch processes into a single integrated continuous production line. Facilities for granulating, drying, grading, mixing, and compression molding are merged into one continuous system where materials flow through all stages without interruption, reducing total space requirements while maintaining manufacturing flexibility.
2Device complexity
If batch method is used for tablet production, then facility design can be simplified for each process, but occupation of large space is required
Solution Approach 1:
The patent combines multiple separate batch processes into a single integrated continuous production line. Facilities for granulating, drying, grading, mixing, and compression molding are merged into one continuous system where materials flow through all stages without interruption, reducing total space requirements while maintaining manufacturing flexibility.
Solution Approach 2:
The continuous production line is designed as a universal system that handles multiple operations (granulating, drying, grading, mixing, compression) in sequence within a single integrated facility, reducing the need for separate dedicated spaces for each process while maintaining the ability to optimize each stage.
3Device complexity
If conventional mixing monitoring is used, then sensor configuration is simple, but mixing degree cannot be promptly monitored and corrective action is delayed
Solution Approach 1:
The patent incorporates sensors that continuously monitor the mixing degree of powdery materials in real-time during the mixing process. The measured mixing degree information is fed back to the control system, which automatically adjusts mixing parameters or feed rates to maintain the mixing degree within the predetermined range, enabling prompt detection and correction of mixing issues.
Solution Approach 2:
The patent replaces conventional mechanical sampling and offline analysis methods with optical or electromagnetic sensors that non-invasively measure mixing degree in real-time. This substitution enables continuous monitoring without disrupting the production flow and provides immediate feedback for corrective action.
4Quantity of substance
If batch production is used, then material usage for verification experiments is reduced, but production efficiency and timeliness are compromised
Solution Approach 1:
The patent implements continuous processing where granulating, drying, grading, mixing, and compression molding are conducted without standby periods between processes. Intermediate products are continuously fed from one process to the next, eliminating idle time and maintaining continuous operational flow throughout the production line.
