Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water cooling is used for the reagent cool storage case, then the cooling effect is achieved, but external air is not efficiently cooled or dried leading to dew condensation
Solution Approach 1:
The patent divides the cooling system into two independent parts: a water cooling system for cooling the reagent storage space, and an air cooling system for cooling and drying external air. The water cooling system uses cooling water channels to cool the reagent containers, while the air cooling system uses separate air channels with cooling fins to cool and dry external air before discharge, preventing dew condensation.
Solution Approach 2:
The patent introduces an intermediary air cooling system that acts as a mediator between the external environment and the reagent storage space. This system cools and dries external air using cooling fins and discharge it through dedicated discharge holes, preventing direct contact between humid external air and cold surfaces that would cause dew condensation.
2Reliability
If external air is introduced to suppress dew condensation, then positive pressure is achieved, but dew condensation may still occur in the air introduction path
Solution Approach 1:
The patent applies local quality by providing cooling fins specifically in the regions where air channels are located. This localized cooling structure efficiently cools and dries external air in the air introduction path, preventing dew condensation in this specific area while maintaining the overall positive pressure system.
Solution Approach 2:
The patent implements preliminary action by cooling and drying external air before it is discharged into the reagent storage space. The air cooling system with cooling fins pre-cools and dries the external air, ensuring that when the air is discharged through the discharge holes, it cannot cause dew condensation on cold surfaces.
3Temperature
If cooling water flow path is placed outside the inner wall, then reagent cooling is efficient, but external air discharge may cause dew condensation
Solution Approach 1:
The patent segments the cooling and air discharge functions into separate systems. The water cooling system with external cooling water channels efficiently cools reagent containers, while the air cooling system with separate air channels and cooling fins handles external air cooling and drying, preventing interference between the two functions.
Solution Approach 2:
The patent introduces an intermediary air cooling system that mediates between the external environment and the reagent storage space. This system cools and dries external air using cooling fins and discharges it through dedicated discharge holes, preventing direct contact between humid external air and cold surfaces that would cause dew condensation.

AI summary
An automatic analyzer with a water-cooled reagent cool storage case efficiently cools and dries an external air before discharging it into an inner space, thereby suppressing dew condensation in an unintended place. In the automatic analyzer with a reagent cool storage case that cools a reagent, the reagent cool storage case includes: a cooling water flow path that supplies cooling water to outside an inner wall comparting a space for housing a reagent container and cools the inner wall; and an air flow path that supplies air to inside the inner wall and makes the space have a positive pressure. A cooling water inflow hole is formed at a specified position of the lower surface of the cooling water flow path located under the bottom surface of the space, and a portion of the air flow path located on the upper surface of the inner wall comparting the bottom surface of the space is positioned on the vertical projection of the cooling water inflow hole.
