Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new processing task is implemented on an existing processing machine, then production flexibility and adaptability are improved, but the risk of contamination from previous tasks increases
Solution Approach 1:
A cleaning device is introduced as an intermediary between processing tasks to remove contaminants from the processing machine. The cleaning device executes cleaning tasks that generate cleaning signals, which are sent to the control device to initiate appropriate cleaning routines, thereby preventing contamination while maintaining production flexibility.
Solution Approach 2:
The system performs preliminary cleaning actions before changing processing tasks by monitoring process parameters that indicate contamination risk. When contamination is detected or anticipated, the control device automatically initiates cleaning routines in advance, ensuring the machine is clean before the next task begins.
2Object-affected harmful factors
If manual cleaning and changeover procedures are used, then contamination risk is reduced, but productivity and efficiency deteriorate
Solution Approach 1:
The processing machine performs self-cleaning through automated cleaning routines executed by an integrated cleaning device. The control device automatically monitors process parameters, determines when cleaning is needed, and initiates cleaning sequences without manual intervention, thereby maintaining contamination control while eliminating productivity losses associated with manual changeover procedures.
Solution Approach 2:
The system uses feedback from process parameters (such as temperature, pressure, or sensor readings) to automatically determine when cleaning is required. The control device receives continuous feedback during processing and initiates cleaning routines based on this feedback, eliminating the need for manual monitoring and intervention while maintaining contamination control.
3Object-affected harmful factors
If comprehensive cleaning routines are executed between tasks, then contamination is prevented, but processing time and productivity decrease
Solution Approach 1:
The system performs partial cleaning actions based on the actual contamination risk assessed from process parameters. Instead of executing comprehensive cleaning routines for every task change, the control device determines the appropriate level of cleaning needed based on the specific processing history and contamination indicators, thereby preventing unnecessary time loss while maintaining adequate contamination prevention.
Solution Approach 2:
The cleaning intensity and duration are dynamically adjusted based on process parameters such as temperature, pressure, and sensor readings. The control device modifies cleaning parameters in real-time according to the actual contamination risk, executing more intensive cleaning only when necessary and lighter cleaning when process conditions indicate low contamination risk, thereby optimizing the balance between contamination prevention and processing time.
