Innovation Solution
A washing method for the staining bath in a smear sample preparing apparatus, which includes a controller that receives information on washing conditions and executes appropriate washing operations based on these conditions, using different concentrations and times of washing liquids to effectively remove precipitated solid components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the staining liquid is left stored in the staining liquid bath, then the staining process can be continuously performed, but solid components are precipitated from the staining liquid and adhered to the sample, reducing the quality of the sample
Solution Approach 1:
The system performs a washing operation before the staining process to remove precipitated solid components from the staining liquid bath. This preliminary cleaning action prevents the solid components from adhering to samples during subsequent staining operations, thereby maintaining sample quality while enabling continuous operation.
Solution Approach 2:
The system implements a continuous washing operation that is performed repeatedly during the staining process. The washing liquid is continuously circulated through the staining liquid bath to remove precipitated solid components, ensuring that the staining process can continue without degradation of sample quality.
2Reliability
If a washing operation is performed to remove solid components, then the sample quality is maintained, but the washing process may not be appropriate for all states of the smear sample preparing apparatus
Solution Approach 1:
The washing operation is made dynamic and adaptable by adjusting parameters such as washing liquid concentration, washing time, and washing liquid temperature based on the actual state of the staining liquid bath. The system can modify the washing process to match different operational conditions, ensuring optimal cleaning effectiveness for various states of the smear sample preparing apparatus.
Solution Approach 2:
The system changes washing parameters including concentration of washing liquid, duration of washing operation, and temperature of washing liquid according to the state of the staining liquid bath. This parameter adjustment allows the washing process to be optimized for different conditions, enhancing both effectiveness and adaptability.
3Productivity
If the washing liquid concentration is increased to remove solid components more effectively, then the cleaning efficiency is improved, but the washing time and resource consumption increase
Solution Approach 1:
The system optimizes the balance between washing liquid concentration and washing time by dynamically adjusting these parameters. Instead of using high concentration continuously, the system can vary the concentration levels and washing duration based on the actual need, achieving effective cleaning while minimizing time consumption and resource usage.
