Quick Connect Gravity Feed Bottle for MICR Ink Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital inline printing systems for continuous web media face complexity and cost issues, especially when handling Magnetic Ink Character Recognition (MICR) ink, which can cause skin irritation due to Ethylene Glycol content, necessitating a safer and more economical ink supply system.
Innovation Solution
A quick connect gravity feed multipurpose bottle apparatus with a printer liquid replenishing bottle, first and second quick connect fittings, and a bottle loading mechanism that securely attaches to a support frame, allowing for efficient ink supply and replacement without direct air contact with the ink, preventing skin irritation and maintaining a continuous ink flow to print heads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If external ink reservoirs are used to supply large quantities of ink to continuous web printers, then the ink supply capacity is improved, but the system complexity and cost increase
Solution Approach 1:
The ink supply system is divided into modular components: external reservoirs are segmented into multiple color stations, each with independent quick-connect fittings. The bottle apparatus is segmented into a reservoir portion and a neck portion with separate quick-connect fittings for ink supply and air venting, allowing independent assembly and maintenance of each module.
Solution Approach 2:
The system employs gravity-fed ink flow where the external reservoirs automatically supply ink to the print heads without requiring active pumping or complex control systems. The quick-connect fittings enable automatic recognition and sealing when bottles are installed, reducing the need for manual configuration or calibration.
2Adaptability or versatility
If MICR ink is used for financial documents, then the printing functionality is improved, but the safety risk increases due to skin irritation from Ethylene Glycol content
Solution Approach 1:
The harmful ink is extracted from the operator's environment by using sealed quick-connect fittings that prevent direct contact. The ink remains contained within the closed system of the bottle and printer, with only sealed mechanical connections exposed to the outside, eliminating the need for operators to handle or transfer the toxic ink manually.
Solution Approach 2:
The quick-connect fittings serve as intermediaries between the external ink reservoir and the printer's internal supply system. These sealed mechanical connectors mediate the ink transfer process, allowing ink flow while maintaining a physical barrier that protects operators from direct exposure to the harmful MICR ink.
3Ease of operation
If quick connect fittings are used for bottle installation, then the ease of operation is improved, but the risk of fluid leakage increases
Solution Approach 1:
The quick-connect fittings are pre-configured with integrated sealing mechanisms and alignment features that automatically engage when the bottle is installed. The fitting design includes pre-positioned seals and mating surfaces that ensure proper alignment and sealing before ink flow begins, preventing leakage while maintaining ease of installation.
4Productivity
If air venting is allowed during ink supply, then the continuous flow is improved, but the risk of ink oxidation increases
Solution Approach 1:
A separate air venting quick-connect fitting serves as an intermediary pathway for air to enter the reservoir during ink depletion. This dedicated vent fitting allows atmospheric pressure to equalize with the reservoir interior, maintaining continuous ink flow through the supply system while the sealed ink pathway prevents air from contacting and oxidizing the ink.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures a continuous ink supply to print heads while minimizing skin contact risks and operational costs by using a sealed, easy-to-refill design that prevents air from entering the ink reservoir, reducing the risk of ink oxidation and maintaining print quality.
Implementation Method 1
The closure has a first port and a second port separate from the first port. The first quick connect fitting is sealingly connected to the first port of the closure, with the first quick connect fitting configured for fluid communication with the liquid supply tank of the inkjet image forming device to allow egress of the liquid from the printer liquid replenishing bottle to the liquid supply tank. The second quick connect fitting is sealingly connected to the second port of the closure, with the second quick connect fitting configured to allow fluid ingress only into the printer liquid replenishing bottle without fluid flow through the liquid housed in the printer liquid replenishing bottle.

AI summary
A spill proof, user-friendly dispensing system that protects users from exposure to toxic fluids (e.g., Ethylene Glycol used in MICR ink) includes a bottle loading mechanism for feeding ink or other fluids to a respective supply tank of an image forming device, and a quick connect gravity feed multipurpose bottle apparatus. Ink replenishing bottles can be inserted upright into holder of the bottle loading mechanism, connected to a supply tank, and folded back out-of-the-way in a dispensing position. The bottle may be rotated from a gravity feed position to a rotated position for removal and installation while the bottle remains in the holder. The bottle when empty may be used to collect waste from the image forming device.
