Print Materials Container In-Situ Replenishment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replenishing print materials in printing devices are often messy, prone to spills, and require manual removal and replacement of reservoirs, leading to potential over- or under-filling and increased operational costs.
Innovation Solution
A print materials container with integrated mechanisms such as a compression mechanism, squeeze bottle mechanism, or accordion-shaped collapsible container, which allows for in-situ replenishment of print materials directly into the printing device's reservoir, minimizing manual handling and spill risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual removal and replacement of reservoirs is used for replenishing print materials, then the reservoir can be replaced with a full one, but the process is messy, prone to spills, and requires significant manual handling
Solution Approach 1:
The invention extracts the print materials from the removable reservoir and transfers them directly into the printing device's reservoir through a replenishment port. This allows the reservoir to remain in place while being refilled, eliminating the messy manual handling associated with removing and replacing entire reservoirs.
Solution Approach 2:
The print materials container is designed to be inserted through the replenishment port and nested within the printing device's reservoir system. This nested configuration allows for direct transfer of materials without external manual handling, reducing spills and operational complexity.
2Quantity of substance
If reservoirs are manually removed and replaced for replenishment, then the printing device can be refilled, but over- or under-filling occurs leading to increased operational costs
Solution Approach 1:
The replenishment system incorporates feedback mechanisms that monitor the transfer of print materials from the container to the reservoir. This feedback control ensures accurate filling levels, preventing over- or under-filling and thereby reducing operational costs associated with material waste or insufficient supply.
Solution Approach 2:
The invention replaces manual mechanical handling of reservoirs with an automated transfer mechanism. The system uses controlled material transfer through the replenishment port, substituting human operation with automated control to achieve precise filling and improve operational efficiency.
3Productivity
If the reservoir remains in-situ during filling, then the replenishment process is faster and cleaner, but a dispense mechanism is required to transfer materials
Solution Approach 1:
The dispense mechanism is designed to be self-contained within the print materials container, which is inserted through the replenishment port. The mechanism automatically dispenses materials from the container into the reservoir without requiring external intervention or complex external systems, enabling fast and clean replenishment while managing complexity within the portable container.
4Reliability
If a lock feature is integrated with the dispense mechanism, then connection to the fill port is secure, but the mechanism becomes more complex
Solution Approach 1:
The lock feature is merged with the dispense mechanism as an integrated component rather than a separate system. This combination provides secure connection to the fill port while minimizing overall complexity by consolidating functions within the portable print materials container.

AI summary
In some examples, a print materials container can include a dispense mechanism to dispense print materials directly to an in-situ reservoir of a printing device, a lock feature to engage a fill port during connection of the dispense mechanism to the fill port, and a valve integrated with the dispense mechanism for connecting the dispense mechanism to the fill port of the reservoir and comprising an output opening offset from a center axis of a tip of the dispense mechanism. The valve can open responsive to rotation of the valve opening with respect to the lock feature such that opposite openings align.
