Ink Container Lid Structure for Bubble-Free Recording Head Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet recording devices face issues with ink quality deterioration due to bubbles entering the recording head, leading to ejection errors and image quality degradation.
Innovation Solution
A liquid container with a design that includes a main body portion, a lid portion, a liquid flow inlet, a liquid flow outlet, and a bubble exhaust port, where the inlet, outlet, and exhaust port are integrated into the lid portion to manage ink flow and bubble discharge efficiently, preventing bubbles from reaching the recording head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid container uses a conventional design with separate inlet and outlet structures, then the device complexity is reduced, but bubbles enter the recording head causing ejection errors and image quality degradation
Solution Approach 1:
The patent combines the liquid flow inlet, liquid flow outlet, and bubble exhaust port all in the lid portion of the container. This merging of multiple functions into a single structural component allows efficient bubble discharge while maintaining liquid flow, resolving the contradiction between reliability (preventing bubble-induced ejection errors) and device complexity (avoiding overly complex container structures)
Solution Approach 2:
The patent extracts the bubble exhaust function by providing a dedicated bubble exhaust port separate from the liquid flow path. This extraction allows bubbles to be removed independently from the liquid flow, preventing bubble contamination of the recording head while keeping the overall structure relatively simple through functional separation
2Productivity
If the liquid container includes integrated inlet, outlet, and exhaust port in the lid portion, then bubble discharge efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent merges the liquid flow inlet, liquid flow outlet, and bubble exhaust port all in the lid portion of the container. This merging of multiple functions into a single structural component allows efficient bubble discharge while maintaining liquid flow, resolving the contradiction between reliability (preventing bubble-induced ejection errors) and device complexity (avoiding overly complex container structures)

AI summary
A liquid container includes a main body portion having a bottom part and a side wall part, so as to store liquid in a containing region enclosed by the bottom part and the side wall part, a lid portion that covers the containing region from above, a liquid flow inlet that allows the liquid to flow into the containing region, a liquid flow outlet that allows the liquid to flow out from the containing region to a feed destination, and a bubble exhaust port that discharges bubbles in the containing region. The liquid flow inlet, the liquid flow outlet, and the bubble exhaust port are all disposed in the lid portion.
