Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional oil state monitoring methods are used, then the monitoring process is simple, but the measurement precision and reliability of oil state assessment are insufficient
Solution Approach 1:
The patent introduces an index member as an intermediary object that interacts with the oil to be detected. The index member's physical or chemical properties change in response to oil state variations, converting invisible oil deterioration into visible changes that can be captured by the photographing device, thereby improving measurement precision without requiring complex direct sensing mechanisms
Solution Approach 2:
The patent replaces traditional mechanical or chemical oil analysis methods with an optical detection system. By using a photographing device to capture images of the index member and analyzing the images through image processing, the system substitutes complex mechanical sampling and laboratory analysis with a simpler optical field-based detection approach
Solution Approach 3:
The patent utilizes color or optical property changes of the index member as oil state deteriorates. The index member is designed to exhibit visible changes in color, transparency, or other optical characteristics when exposed to deteriorated oil, allowing the photographing device to detect oil quality through image analysis of these visual changes
2Productivity
If manual oil inspection methods are used, then the device complexity is low, but the productivity and efficiency of maintenance operations are reduced
Solution Approach 1:
The system enables automatic oil state detection without requiring manual intervention for sampling or analysis. The photographing device automatically captures images of the index member, and the control device automatically processes these images to determine oil state, allowing the system to monitor itself continuously and generate maintenance alerts autonomously
Solution Approach 2:
The patent implements continuous or periodic automatic monitoring of oil state through the photographing device and control device. Instead of intermittent manual inspections, the system maintains continuous surveillance of oil condition, enabling timely detection of deterioration trends and proactive maintenance scheduling, thereby improving overall maintenance efficiency
3Measurement precision
If frequent manual oil sampling is performed, then the measurement frequency increases, but the loss of time and operational disruption increase
Solution Approach 1:
The patent replaces manual oil sampling and laboratory analysis with an in-situ optical detection system. The photographing device captures images of the index member directly within the machine's oil system, and the control device performs automated image processing to assess oil state, eliminating the need for time-consuming manual sampling, transportation, and laboratory testing procedures
Solution Approach 2:
The index member serves as a mediator that remains continuously exposed to the oil being monitored. By photographing the index member in place, the system obtains real-time oil state information without removing oil samples from the system or disrupting machine operation, thus avoiding time loss associated with traditional sampling methods
