Molding Machine Pressure Profile Diagnosis System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring systems for molding and pressing machines rely on human judgment for diagnosing operating states, which is inefficient and prone to errors due to the complexity of pressure profiles and varying parameters, making it difficult to accurately diagnose the suitability of operating conditions without experienced inspectors.
Innovation Solution
A diagnostic system that includes sensors for measuring actual pressure profiles, a database for storing reference profiles, and a comparison mechanism to determine if the actual profiles are within predetermined tolerances, with the ability to update reference profiles and visually display deviations, allowing for automated diagnosis of both pressure profiles and processing times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated diagnosis is implemented, then productivity and reliability are improved, but device complexity increases
Solution Approach 1:
The patent replaces manual inspection (mechanical human judgment) with an automated computer-based diagnosis system that uses sensors, databases, and algorithms to automatically compare actual pressure profiles against reference profiles and determine compliance with preset conditions, thereby improving productivity while managing system complexity through automation
Solution Approach 2:
The diagnosis system performs self-diagnosis by automatically collecting data via sensors, comparing it with reference data from the database, and determining whether operating states comply with preset conditions without requiring external human intervention, enabling the system to serve itself in the diagnosis process
2Measurement precision
If manual inspection by experienced inspectors is used, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent replaces the mechanical process of manual inspection by experienced inspectors with an automated computer-based system that uses sensors to collect data, compares it with reference profiles in a database, and automatically determines compliance, thereby eliminating time loss while maintaining or improving measurement precision through consistent algorithmic evaluation
Solution Approach 2:
The system creates a digital copy of the inspection process by storing reference pressure profiles and preset conditions in a database, allowing the computer to replicate and execute the diagnostic judgment process automatically without requiring physical human inspection, thus preserving accuracy while eliminating time consumption
3Ease of operation
If automated diagnosis system is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The diagnosis system operates autonomously by automatically collecting pressure profile data through sensors, retrieving reference profiles from the database, performing comparisons, and determining compliance with preset conditions without requiring operator intervention, thereby greatly improving ease of operation while the underlying system complexity is managed through automation
Solution Approach 2:
The computer-based diagnosis system performs multiple functions including data collection, database management, comparison analysis, and compliance determination within a single integrated platform, improving ease of operation by consolidating functions while managing overall system complexity through multi-functionality

AI summary
A diagnostic system to diagnose a pressure profile of a molding machine M in an operating state is disclosed. The pressure profile of the molding machine M in the operating state is measured with a pressure sensor of a measurement system 3. In a diagnostic system A, a database is formed such that a reference pressure profile and the actual pressure profile selected according to a mold to be made are preserved therein. The diagnostic system A compares the reference pressure profile to the actual pressure profile in the database to determine whether the actual pressure profile is within a predetermined tolerance.
