Ink Chamber Frame Structure With Ink Return to Prevent Overflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink overflow and environmental pollution occur due to wear of ink stopper blocks in traditional ink chamber devices, necessitating frequent replacement and increased cleaning efforts.
Innovation Solution
An ink chamber frame structure with two first ink stopper blocks and a lower scraper divides the chamber into a wiping area and ink return areas, allowing excess ink to flow into ink return areas via ink return holes, connected to a circulation device, and features detachable stopper blocks for easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ink stopper blocks are used in the ink chamber device, then the ink chamber can be sealed to contain ink, but the stopper blocks wear away over time causing gaps that lead to ink overflow and pollution
Solution Approach 1:
The ink chamber is divided into multiple functional zones by partition walls: a wiping area between the ink stopper blocks, and ink return areas on both sides. This segmentation allows different regions to serve different purposes - the wiping area accumulates excess ink while the ink return areas receive and channel the ink back, preventing overflow at the ends of the ink roller.
Solution Approach 2:
The partition walls act as intermediary structures that guide ink flow from the wiping area to the ink return areas. The first ink return holes provide intermediate pathways for ink to flow back before reaching the end gaps, serving as a mediator to prevent direct overflow from the worn stopper blocks.
2Quantity of substance
If ink accumulates in the entire ink chamber, then the ink roller can be evenly coated, but excess ink causes overflow from gaps between worn stopper blocks and ink roller
Solution Approach 1:
Different regions of the ink chamber have different functions and ink levels. The wiping area between the stopper blocks maintains sufficient ink quantity for roller coating, while the ink return areas at the ends maintain lower ink levels to prevent overflow. This local differentiation of ink quantity and function prevents harmful overflow while ensuring adequate ink supply.
Solution Approach 2:
The worn gaps between the stopper blocks and ink roller, which originally caused harmful ink overflow, are converted into beneficial ink return pathways. The partition walls and ink return holes guide the ink that would have spilled outward to instead flow back into the ink chamber through controlled paths, turning a harmful leakage issue into a useful ink circulation mechanism.
3Loss of time
If ink stopper blocks are not replaced regularly, then maintenance time is reduced, but ink sprays out from gaps causing environmental pollution and requiring extensive cleaning
Solution Approach 1:
The ink chamber device performs self-service by automatically returning overflow ink to the ink chamber through the ink return holes and circulation device. This self-circulation mechanism compensates for the wear of stopper blocks without requiring external intervention or frequent manual replacement, reducing maintenance time while preventing pollution.
4Reliability
If the ink chamber is divided into wiping area and ink return areas, then ink overflow is prevented, but the device structure becomes more complex
Solution Approach 1:
The partition walls serve multiple functions simultaneously: they divide the ink chamber into different areas, provides structural support, guide ink flow pathways, and work with the ink return holes to create the overflow prevention mechanism. By merging these functions into a single structural element, the complexity is reduced compared to having separate components for each function.
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
Prevents ink overflow, reduces ink consumption by recycling, and minimizes labor and time costs associated with stopper block replacement.
Implementation Method 1
After the ink accumulation exceeds the height of the two tops of the two first ink stopper blocks, the ink will flow over the two tops of the two first ink stopper blocks and flow to the two ink return areas

AI summary
An ink chamber frame structure includes an ink chamber frame including a lower ink chamber frame component and an ink shield having a lower side connected to the lower ink chamber frame component and a front surface provided with an ink roller with left and right ends thereof corresponding to the left and right ends of the ink shield, two first ink stopper blocks placed on the front surface of the ink shield, and a lower scraper installed on the lower ink chamber frame component and incorporated with the ink shield, the ink stopper blocks and the ink roller to form an ink chamber. when the ink roller is in use, the ink accumulated in the ink chamber will only accumulate to the height of the two first ink stopper blocks, and will not accumulate to the entire ink chamber.
