Liquid Container Injection Port with Reception Area for Ink Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid ejecting apparatuses, such as printers, the frequent replacement of ink cartridges due to limited size and the risk of ink leakage and contamination during ink replenishment is a challenge, as small injection ports can lead to ink evaporation or dust entry, and leaked ink can scatter and contaminate the surrounding area.
Innovation Solution
A liquid ejecting apparatus design featuring a liquid container with an injection port and a liquid reception portion on its lower side, an inclined surface for ink collection, and a storage area to manage leaked ink, along with a protruding portion for easy ink injection and reduced contamination, supported by a container support to minimize leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the opening size of the injection port is made small to prevent ink evaporation and dust entry, then the sealing performance is improved, but ink leakage during injection becomes more difficult to control and may scatter
Solution Approach 1:
A reception portion is introduced as an intermediary component between the injection port and the external environment. This reception portion captures any leaked ink during the injection process, preventing it from scattering. The reception portion acts as a buffer zone that allows the injection port to maintain a small opening size for better sealing while providing a safety mechanism for ink containment during the injection operation.
2Productivity
If ink is injected into the liquid container through the injection port, then the ink replenishment function is achieved, but ink leakage may occur and contaminate the surrounding area
Solution Approach 1:
The reception portion is designed to capture and contain ink that leaks during the injection process. By providing this dedicated reception area, the system converts the harmful effect of ink leakage into a controlled situation where the leaked ink is contained within the reception portion rather than scattering and contaminating the surrounding environment. This allows the ink replenishment function to proceed without the fear of uncontrolled contamination.
3Volume of moving object
If the liquid container is made compact to fit in the casing body, then the device size is reduced, but the frequency of ink cartridge replacement increases
Solution Approach 1:
The invention extracts the ink replenishment operation from the traditional replaceable cartridge system. By providing an injection port and reception portion on the liquid container, the system allows ink to be replenished in place through injection, rather than requiring complete cartridge replacement. This separates the container body from the consumable ink supply, enabling independent refilling and reducing replacement frequency.
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
This configuration effectively suppresses ink scattering and contamination by collecting and storing leaked ink, reducing the frequency of ink replenishment and maintaining a clean environment within the apparatus.
Implementation Method 1
an inclined portion inclined downward be provided on an upper surface side of the liquid reception portion. According to the configuration, the liquid received by the liquid reception portion flows along the inclined portion and is collected in the lower side.
