Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing briquetting machine control methods struggle to adjust operating conditions effectively to maintain consistent briquette quality due to variations in raw material state and humidity, making it difficult to determine how to adjust the machine's settings when the produced briquettes deviate from desired quality.
Innovation Solution
An evaluation device and method that acquires and compares evaluation information from multiple briquettes manufactured under the same conditions, generating evaluation data to display on a graph, allowing for the determination of whether to change operating conditions based on a distribution plot of first and second evaluation parameters, thereby facilitating adjustments to achieve target quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If operating conditions are controlled based on distortion value of compression roller support portion, then manufacturing precision of briquette quality is improved, but adaptability to raw material variations and humidity changes deteriorates
Solution Approach 1:
The system implements feedback control by measuring the actual briquette quality (compression strength, moisture content, etc.) and using this information to adjust operating conditions. The control device receives quality data from measurement devices and modifies compression force, roller speed, and other parameters to maintain desired quality levels despite raw material variations.
Solution Approach 2:
The system dynamically changes operating parameters such as compression force, roller rotation speed, and moisture content based on measured briquette quality and raw material characteristics. By adjusting multiple parameters simultaneously, the system adapts to variations in raw material properties and environmental conditions while maintaining consistent briquette quality.
2Adaptability or versatility
If multiple evaluation parameters are measured and compared, then adaptability to maintain quality under varying conditions is improved, but device complexity increases
Solution Approach 1:
The control device serves multiple functions: it controls compression force, regulates roller speed, monitors moisture content, and adjusts operating conditions based on various evaluation parameters. By integrating these functions into a single multi-functional control system, the patent reduces overall system complexity while maintaining the ability to respond to multiple quality parameters simultaneously.
Solution Approach 2:
The system combines multiple measurement devices (compression strength meters, moisture sensors, etc.) and control functions into an integrated evaluation and control system. By merging these components and coordinating their operation through a central control device, the system achieves comprehensive quality monitoring without proportionally increasing complexity.
3Measurement precision
If distortion measurement is used to directly ascertain compressive load, then measurement precision of compression force is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically measures distortion, calculates compressive load, and adjusts operating conditions without requiring manual intervention. The control device autonomously processes measurement data from distortion sensors and other evaluation parameters, making operational decisions and adjusting parameters to maintain optimal briquette quality, thereby simplifying operator tasks.
