Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators manually specify and adjust process parameters during production, then the machine can be controlled, but the setup complexity and operation difficulty increase significantly
Solution Approach 1:
The patent creates a digital copy (virtual model) of the blow molding machine that replicates its pneumatic behavior. This virtual model allows operators to determine process parameters offline through simulation rather than manual adjustment during production, significantly simplifying operation while capturing the complex system behavior in the digital replica
Solution Approach 2:
The patent performs parameter determination in advance using the virtual model before actual production starts. All complex calculations and parameter optimizations are completed beforehand, eliminating the need for operators to make complex adjustments during production, thus improving ease of operation during actual manufacturing
2Productivity
If process parameters are determined using a virtual model offline, then production time is reduced and self-regulation is achieved, but the initial setup requires complex model development
Solution Approach 1:
The patent implements feedback loops where measurement data from real machine operations is continuously used to update and refine the virtual model. This feedback mechanism allows the model to self-improve and adapt to actual machine behavior, reducing the manual effort required for model creation while maintaining high accuracy for parameter determination
Solution Approach 2:
The virtual model is designed to automatically determine process parameters without requiring continuous manual intervention. Once established, the system performs self-regulation by autonomously calculating optimal parameters based on production requirements, significantly boosting productivity while reducing operational complexity
3Manufacturing precision
If continuous readjustment is performed during production operation, then process optimization is achieved, but production time is lost and efficiency decreases
Solution Approach 1:
The patent determines all necessary process parameters in advance using the virtual model before production begins. By performing the complex parameter optimization work beforehand rather than during production, the system achieves high manufacturing precision without sacrificing production time, as no readjustments are needed during actual manufacturing operations
