Solution Approach 1:

The system divides the sequencing process into modular components: a cartridge containing multiple containers with different reagents (nucleotide concentrates, enzymes, buffers) that can be independently prepared and stored, then combined with an initial solution in controlled proportions through a fluidic system. This segmentation allows cost reduction by enabling separate preparation of inexpensive reagent concentrates while maintaining sequencing capability through systematic combination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary fluidic system comprising a cartridge, containers, and flow paths that mediates between the initial solution storage and the sequencing reaction. This intermediary system enables automated mixing and delivery of reagents, reducing manual preparation costs while ensuring reliable sequencing through controlled fluid delivery and systematic reagent combination.

Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The system performs preliminary action by pre-preparing and storing individual reagent concentrates (nucleotide concentrates, enzyme concentrates, buffer solutions) in separate containers within the cartridge before the actual sequencing process. These pre-prepared concentrates are then combined with the initial solution through automated fluidic delivery, simplifying the preparation process while maintaining reagent quality through controlled mixing and delivery.

Inventive Principle:

Solution Approach 2:

The cartridge system enables self-service by containing all necessary reagent concentrates and delivery mechanisms in an integrated unit that automatically mixes and delivers the correct proportions of reagents when connected to the sequencing instrument. This self-contained system reduces manual preparation complexity while ensuring consistent reagent quality through automated control.
