Foundry Sand Property Display with Time Series Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for predicting changes in foundry sand properties either use independent measurements of compressive strength and air permeability or combine different sand property measurements but not as time series, leading to incomplete remedial measures and lack of temporal change analysis.
Innovation Solution
A display apparatus that acquires and displays sand properties as time series data, showing relationships between moisture content, compactability, air permeability, and compressive strength, with reference ranges to assist in identifying and addressing deviations and predicting future changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple sand property measurements are used in combination, then the comprehensiveness of analysis is improved, but the complexity of data processing increases
Solution Approach 1:
The patent combines multiple sand property measurements (moisture content, compactability, air permeability, compressive strength) into a single integrated display system that shows all properties simultaneously with their interrelationships, eliminating the need for separate analysis of each property and resolving the contradiction between comprehensive analysis and processing complexity
Solution Approach 2:
The display apparatus serves multiple functions: it displays individual sand property values, shows relationships between different properties, provides reference ranges for evaluation, and enables temporal comparison - all within a single system, thereby improving comprehensiveness without proportionally increasing complexity
2Reliability
If sand properties are measured as time series data, then the ability to predict future changes is improved, but the requirement for data storage and processing increases
Solution Approach 1:
The system performs preliminary data collection and storage of sand properties over time, preparing the data in advance for future analysis and prediction. By continuously accumulating time-series measurements, the system enables reliable prediction of future sand property changes without requiring complex processing at the moment of prediction
Solution Approach 2:
The display apparatus provides visual feedback showing the temporal evolution of sand properties and their interrelationships, allowing operators to observe trends and predict future changes based on historical patterns. This feedback mechanism improves prediction reliability while keeping the processing requirement manageable through graphical visualization
