Multi-Compartment Liquid Supply With Clearance Cutouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensers designed for single-liquid supplies face inefficiencies when trying to accommodate multiple distinct liquid supplies, as they require separate slots and complex latching mechanisms, leading to space inefficiencies and potential misconnection risks.
Innovation Solution
A replaceable multiple compartment liquid supply with integrated outlets and a single latch system that fits into the space of multiple individual slots, using clearance cutouts to align with dispenser protrusions and a single latch for secure locking, allowing easy installation and fluidic connection to multiple compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple individual liquid supplies are used in separate slots, then each liquid can be dispensed independently, but the space occupied increases and the device complexity increases
Solution Approach 1:
The patent combines multiple individual liquid supplies into a single integrated cartridge containing multiple compartments. Each compartment holds a different liquid and connects to the printhead through fluidic pathways. This merging approach allows the dispenser to access multiple distinct liquids while occupying the space of only one supply unit, directly resolving the contradiction between multi-liquid capability and space efficiency.
2Adaptability or versatility
If multiple individual liquid supplies are used in separate slots, then each liquid can be dispensed independently, but the device complexity increases
Solution Approach 1:
The patent consolidates multiple supply units and their associated latching mechanisms into a single cartridge with one latch. This integrated design reduces the number of receiving slots from multiple to one, and simplifies the latching system from multiple individual latches to a single latch that secures the entire multi-compartment cartridge, thereby reducing device complexity while maintaining multi-liquid dispensing capability.
Solution Approach 2:
The single cartridge design serves multiple functions: it holds multiple different liquids in separate compartments, provides fluidic connection for all liquids to the printhead, and uses a single latch mechanism to secure the entire assembly. This multi-functional approach eliminates the need for multiple specialized slots and latching mechanisms, resolving the complexity issue.
3Reliability
If multiple individual liquid supplies are used, then misconnection risks are reduced, but the installation process becomes more complex
Solution Approach 1:
The patent combines multiple liquid supplies into a single pre-configured cartridge with predetermined compartment arrangements and fluidic connections. This integration ensures that when the cartridge is installed in one slot, all liquid pathways are correctly aligned with the printhead, eliminating misconnection risks while simplifying installation to a single insertion and latching action, rather than multiple separate installations.

AI summary
Liquid supply or reservoir therefore having multiple compartments, each compartment to hold a distinct liquid, comprising multiple liquid outlets, each fluidically connected to one of the compartments, multiple clearance cut outs disposed at a pitch equal to a pitch of the compartments to accommodate protrusions of a dispenser, and at least one latch protruding outwards from a supply wall.
