Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time-controlled cleaning is performed without checking necessity, then cleaning operations are executed regularly, but process interruptions increase and resource waste occurs
Solution Approach 1:
The sensor surface state is analyzed before cleaning operations to determine whether cleaning is actually necessary. This preliminary assessment prevents unnecessary cleaning cycles, allowing processes to continue uninterrupted unless the sensor truly requires maintenance.
Solution Approach 2:
The system continuously monitors the sensor surface state and provides feedback about contamination levels. This feedback mechanism enables dynamic decision-making about when cleaning is necessary, optimizing the balance between maintaining sensor reliability and minimizing process interruptions.
2Reliability
If cleaning operations are performed without checking success, then cleaning is executed as a routine task, but cleaning effectiveness cannot be verified
Solution Approach 1:
The system analyzes the sensor surface state both before and after cleaning operations, providing feedback that verifies cleaning effectiveness. This allows determination of whether the cleaning actually improved sensor performance or if further action is needed.
Solution Approach 2:
The sensor state is analyzed before cleaning to establish a baseline, and then analyzed again after cleaning to assess improvement. This preliminary and follow-up assessment provides complete information about cleaning success.
3Reliability
If sensor replacement is performed without analyzing surface state, then sensors are replaced based on fixed schedules, but replacement timing is inefficient
Solution Approach 1:
The system provides continuous feedback about sensor surface contamination levels, enabling dynamic adjustment of replacement schedules. Sensors are replaced only when the analysis shows they no longer meet performance requirements, optimizing maintenance efficiency.
Solution Approach 2:
The system changes the parameter of sensor replacement timing from fixed schedules to condition-based decisions. By monitoring surface state parameters, the system determines optimal replacement moments that balance reliability with productivity.
