Mass-Based Product Tracking in Powder Processing Installations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product tracking methods in installations that process powdered products into manufactured items, such as tablets or capsules, are complex and imprecise, especially when dealing with multiple products, as they rely on time-based dwell time models that require extensive parameterization and are sensitive to operating point deviations.
Innovation Solution
Implementing a mass-based product tracking system using inlet and downstream mass sensors to divide the product into sequential mass units, allowing for precise tracking and assignment of manufactured items, independent of production speed fluctuations, by employing evaluation algorithms that reduce the number of necessary parameters and account for material properties beyond concentration or dwell time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dwell time models are used for product tracking, then product tracking is achieved, but the system complexity and parameterization effort increase significantly
Solution Approach 1:
The patent changes the fundamental parameter basis from time-based dwell time models to mass-based tracking using inlet and downstream mass sensors. This parameter transformation eliminates the need for complex dwell time parameterization while maintaining tracking reliability, as mass measurements directly correlate product input with output without requiring time-dependent modeling.
Solution Approach 2:
The patent replaces the complex computational system of dwell time models with a simpler mass balance approach using direct mass measurements. By substituting time-based computational tracking with mass-based physical measurement, the system achieves comparable or superior reliability with significantly reduced complexity.
2Reliability
If dwell time models are used for product tracking, then product tracking is achieved, but measurement precision decreases due to sensitivity to operating point deviations
Solution Approach 1:
The patent transforms the tracking parameter from time-dependent dwell time to mass-based measurements. This change eliminates sensitivity to operating point deviations because mass conservation holds true regardless of production speed or process variations, thereby maintaining high measurement precision across different operating conditions.
3Adaptability or versatility
If multiple products are fed into the system, then product variety is achieved, but tracking accuracy decreases due to varying dwell times
Solution Approach 1:
The patent creates a universal mass-based tracking system that functions equally well for single products or multiple product combinations. The mass balance approach is product-agnostic, allowing the same system to accurately track any number of products fed into the installation without requiring product-specific parameterization or suffering from varying dwell times.
Data Source
AI summary
A method for tracking product in an installation in which powdered product is processed into manufactured items is provided. The method comprises introducing the powdered product into the installation through at least one inlet, obtaining measurement data for the powdered product from at least one mass sensor positioned in the at least one inlet, and dividing the measurement data into mass units of equal size. The progression of the mass units is then tracked through the installation using measurement data from at least one other mass sensor in the installation.
