Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual maintenance is performed to clean fluid components, then the pump and valve can be cleaned of deposits and crystals, but the maintenance requires significant labor and carries risk of biological contamination
Solution Approach 1:
The system performs automatic self-cleaning through a self-service mechanism where the waste pump and valve are cleaned without manual intervention. The cleaning mechanism injects cleaning solution into the reaction cup, which then flows through the waste pipeline to automatically clean the pump and valve components, eliminating the need for manual disassembly and cleaning by operators.
Solution Approach 2:
The cleaning operation is performed as a preliminary action before the biochemical analyzer is left unused or transported. The control system automatically executes the cleaning sequence, injecting cleaning solution and circulating it through the waste pipeline to prevent deposit formation and crystal accumulation in advance, ensuring components are clean before potential storage or transport conditions.
2Reliability
If periodic maintenance is performed on fluid components, then deposits and crystals can be removed, but there may be a long interval between maintenance actions during which reliability cannot be guaranteed
Solution Approach 1:
The cleaning mechanism enables continuous protection of the fluid components by performing cleaning operations at regular intervals automatically. The control system manages the cleaning sequence continuously, ensuring that the waste pump and valve are repeatedly cleaned of deposits and crystals, maintaining their reliability without long intervals between maintenance actions.
Solution Approach 2:
The system performs automatic self-cleaning through a self-service mechanism where the waste pump and valve are cleaned without manual intervention. The cleaning mechanism injects cleaning solution into the reaction cup, which then flows through the waste pipeline to automatically clean the pump and valve components, eliminating the need for manual disassembly and cleaning by operators.
3Adaptability or versatility
If the biochemical analyzer is emptied for transportation or left unused, then detergent may volatilize and form crystalline particles on pump and valve membranes, but continuous operation is interrupted
Solution Approach 1:
The cleaning operation is performed as a preliminary action before the biochemical analyzer is left unused or transported. The control system automatically executes the cleaning sequence, injecting cleaning solution and circulating it through the waste pipeline to prevent deposit formation and crystal accumulation in advance, ensuring components are clean before potential storage or transport conditions.
Solution Approach 2:
The system converts the potential harm of detergent volatilization and crystal formation into a benefit by using the cleaning mechanism to actively remove deposits and prevent crystal accumulation. The cleaning solution circulation through the waste pipeline transforms the harmful environment into an opportunity for preventive cleaning, ensuring components remain free of crystalline particles even during transport or storage intervals.

Implementation Method 1
Elements such as fat, protein and the like, after being in contact with the fluid components such as the waste pump and waste valve for a long time, will be deposited onto the membranes thereof
Implementation Method 2
a water injection step in which the control system allows at least one of the reagent adding mechanism, the sample adding mechanism and the cleaning mechanism to inject water into at least one reaction cup
Implementation Method 3
a water discharge step in which the control system allows the reaction cup, the cleaning mechanism and the waste pipeline to be in fluid communication, and activates the waste pump to discharge water from the reaction cup through the cleaning mechanism and the waste pipeline
Implementation Method 4
Elements such as reagents, which may contain many complex organic ingredients, after being in contact with membranes of the pump and valve for a long time, will cause a corrosion of the pump and valve
