Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time monitoring and analysis of control and response signals is implemented, then production efficiency and product consistency are improved, but device complexity increases
Solution Approach 1:
An edge device is introduced as an intermediary component between the injection-molding machine and robotic handling device. This edge device captures, transmits, and enables analysis of control and response signals without requiring fundamental changes to the existing machines, thus improving monitoring capabilities while limiting the increase in overall system complexity.
Solution Approach 2:
The edge device is designed to perform multiple functions: capturing control signals from the injection-molding machine, capturing response signals from the robotic handling device, transmitting signals between components, and enabling real-time analysis. This multi-functionality consolidates what could have been multiple separate systems into a single integrated solution.
2Manufacturing precision
If comprehensive signal monitoring and analysis is implemented, then mechanical defects are reduced and product quality is improved, but loss of time for data processing increases
Solution Approach 1:
The edge device captures and transmits control and response signals in real-time during the injection molding process, enabling continuous monitoring without requiring post-process analysis. This preliminary action allows for immediate detection and correction of deviations, maintaining product consistency without significant time loss.
Solution Approach 2:
The system implements feedback by analyzing control and response signals in real-time and enabling adjustments to be made during the molding process. This continuous feedback loop allows for immediate correction of process variations, improving product consistency while minimizing the need for rework and associated time losses.
3Loss of information
If real-time data capture and transmission is implemented, then operational visibility is improved, but use of energy for data processing increases
Solution Approach 1:
The edge device extracts only the essential control and response signals from the complex communication between the injection-molding machine and robotic handling device. By selectively capturing only the most relevant data for monitoring and analysis, the system improves operational visibility while minimizing the energy required for data transmission and processing.
