Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water soaking method is used to remove fixatives, then the toxic chemicals are removed, but the processing time becomes very long and water needs frequent changing
Solution Approach 1:
The patent uses a water spray system with nozzles to deliver cleaning water directly to the sample surface under pressure, replacing the passive soaking method. This hydraulic approach enables rapid removal of fixatives significantly faster than static soaking, reducing processing time while maintaining effective chemical removal.
Solution Approach 2:
The system implements periodic cycles of spraying clean water followed by suction removal, and periodically replaces the cleaning water when it becomes contaminated. This periodic action maintains cleaning efficiency throughout the process without requiring continuous manual intervention or excessively long processing times.
2Reliability
If high concentration fixative chemicals are used, then the sample fixation is effective, but the chemicals become volatile causing discomfort and poisoning to staff
Solution Approach 1:
The patent converts the harmful volatile chemicals into a beneficial cleaning opportunity by immediately spraying and suctioning them off the sample surface. The volatility that causes harm is transformed into an advantage where the chemicals can be rapidly removed through the spray-suction system, protecting staff while maintaining fixation effectiveness.
Solution Approach 2:
The system extracts and removes the toxic fixative chemicals from the laboratory environment by suctioning them away through the exhaust system immediately after application. This extraction prevents the chemicals from volatilizing into the air where they could harm staff, while still allowing the fixation process to occur.
3Productivity
If conventional solvent dilution device is used, then the sample can be processed, but the energy consumption is high
Solution Approach 1:
The system uses the kinetic energy of the sprayed water itself to perform the cleaning function, eliminating the need for separate heating or chemical treatment steps. The spray-suction mechanism relies on fluid dynamics and pressure differentials rather than high-energy inputs, achieving sample processing with minimal energy consumption.
