The engineering focus is on the physical and fluidic coupling mechanisms between modular cartridges and delivery systems. Precise control of these interfaces ensures leak-proof fluidic continuity and reliable ejection performance in modular microfluidic architectures.
The keywords focus on packaging and hooks for dispensers, indicating a need to prevent unintended evaporation or leakage during storage and handling. Preventing early loss of active ingredients ensures product shelf-life and consistent delivery performance.
