A simplified liquid phase analysis device with a first fluid supply system for the sample, a second fluid supply system, an injection valve, and a chromatography column, where the injection valve switches flow paths to enable communication between the fluid supply systems and the chromatography column, reducing the number of components and complexity while using a single constant flow pump and injection valve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving force supply units and switching valves are used to manage different eluents, then the liquid chromatography analyzer can deliver various eluents and samples, but the system complexity increases and implementation costs increase
Solution Approach 1:
The single constant flow pump is designed to perform multiple functions: it can deliver different eluents (first eluent, second eluent) and samples through flow path switching, replacing the need for multiple dedicated driving force supply units. This multi-functional design maintains the ability to handle various fluids while significantly reducing system complexity
Solution Approach 2:
The patent merges the functions of multiple driving force supply units into a single constant flow pump. By combining these functions and using flow path switching to route different fluids to the chromatography column, the system achieves the same operational capabilities with fewer components, thereby reducing both complexity and cost
2Adaptability or versatility
If multiple driving force supply units and switching valves are used, then various eluents can be delivered, but the implementation costs increase
Solution Approach 1:
The single constant flow pump serves multiple purposes by delivering different eluents and samples through flow path control, eliminating the need for multiple expensive dedicated pumps. This universal component approach reduces implementation costs while maintaining the capability to deliver various eluents
Solution Approach 2:
By merging multiple driving functions into one pump system and using flow path switching to manage different fluid deliveries, the patent reduces the number of components that need to be manufactured and assembled, thereby lowering implementation costs
3Adaptability or versatility
If the system uses multiple components for fluid delivery, then various eluents can be managed, but the fluid path length increases
Solution Approach 1:
The patent consolidates fluid delivery through a single pump system with flow path switching, which shortens the overall fluid path compared to having multiple separate delivery systems. The merged architecture eliminates redundant piping and connections that would exist with multiple independent units
