Square Ink Filter Vessel With Hinged Lid For Printing Press
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink filter vessels for printing presses, typically cylindrical or torpedo-shaped, require a minimum height of 18 inches for adequate filtering, making them difficult to install in complex and space-constrained printing press environments, and their lids are cumbersome to attach and detach.
Innovation Solution
A square ink filter vessel with a compact design, featuring a hinged lid and lid compression device that allows for easy attachment and detachment without nuts, and a containment basket with a sloped bottom and internal ledge for efficient ink flow, enabling installation in smaller spaces and simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cylindrical or torpedo-shaped ink filter vessels are used, then adequate filtering surface area is provided, but the height becomes at least 18 inches making installation difficult in space-constrained printing press environments
Solution Approach 1:
The patent transitions from a cylindrical/torpedo shape (vertical orientation) to a square cross-section shape (horizontal orientation). This dimensional change allows the filtering surface area to be achieved within a reduced height profile, enabling installation in space-constrained printing press environments while maintaining adequate filtering capacity through the square cross-sectional geometry
2Reliability
If traditional lids with nuts are used, then secure closure is achieved, but attachment and detachment become difficult and time-consuming
Solution Approach 1:
The patent replaces the traditional nut-based mechanical fastening system with a hinge mechanism that allows the lid to be attached and detached by simple opening and closing motions. This substitution eliminates the need for tools and complex fastening operations, significantly improving ease of operation while maintaining secure closure through the hinged connection and lid compression device
3Area of stationary object
If tall filtering vessels are used, then adequate filtering surface area is provided, but the volume of ink required increases requiring larger pump capacity
Solution Approach 1:
By changing from a vertical cylindrical shape to a horizontal square cross-section shape, the patent reduces the height of the vessel while maintaining adequate filtering surface area through the square cross-sectional geometry. This dimensional change decreases the overall volume of ink required in the vessel, allowing for smaller pump capacity requirements while preserving filtering effectiveness

AI summary
A square ink filter vessel for a printing press, like a rotogravure printing press, a flexographic printing press, or other like printing presses, includes a container having a substantially rectangular shaped cross-section with an open top, an outlet port on one side approximate the bottom of the container, a sloped bottom, where the sloped bottom being toward the outlet port, an inlet port on one side approximate the top of the container, and an internal ledge. A lid is adapted to close the open top of the container. A hinge couples the lid to the container, where the lid is hinged to the container on one side. A lid compression device is adapted to compress the lid to the container. A containment basket is adapted to fit inside the container, and has a plurality of holes on all sides and a lip adapted to rest on the internal ledge of the container.
