Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a loading system is provided on a fixed disk to allow independent reagent container changes, then reagent replacement becomes possible during analysis, but the device structure becomes complex and operator reliability is not ensured
Solution Approach 1:
The reagent container transport tool is made movable between elevated and lowered positions, allowing dynamic access to the reagent container loading portion. This enables operator intervention when needed while maintaining automation during normal operation, resolving the contradiction between productivity and device complexity.
Solution Approach 2:
The reagent container transport tool and shielding member are extracted as separate, movable components from the fixed disk structure. This extraction allows the loading system to be simplified while maintaining the capability for independent reagent container changes, reducing device complexity while preserving productivity.
2Ease of operation
If the reagent container transport tool is always accessible, then operator can easily replace reagents, but contamination risk increases and device reliability decreases
Solution Approach 1:
The shielding member dynamically covers the reagent container loading portion when the transport tool is in the lowered position, preventing contamination. When the transport tool is elevated, the shielding member moves away to allow operator access. This dynamic mechanism resolves the contradiction between ease of operation and reliability.
3Ease of operation
If guide grooves are arranged radially on the loading portion, then reagent container insertion is facilitated, but the device structure becomes more complex
Solution Approach 1:
The radially arranged guide grooves create equipotential pathways that naturally guide reagent containers into the correct positions on the transport tool. This passive guiding mechanism reduces the need for complex active positioning systems, resolving the contradiction between ease of operation and device complexity.
