Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid ejecting apparatuses, such as inkjet printers, the position of large intermediate ink tanks can deviate due to manufacturing or attachment errors, leading to connection failures and ink leakage, especially when the tanks are externally mounted and require frequent replacement.
Innovation Solution
A liquid ejecting apparatus with a position adjusting unit that allows the liquid container to be moved in a direction intersecting the connecting direction, using a rotating member with a screw pair and a movable member to support the container's weight and maintain proper alignment, reducing sliding resistance with a curved tip end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large intermediate ink tank is used to accommodate large volume printing, then the ink supply capacity is improved, but the position deviation due to manufacturing and attachment errors increases, leading to connection failures
Solution Approach 1:
The patent introduces a position adjusting unit that enables dynamic adjustment of the liquid container's position in the connecting direction. This allows the system to adapt to position deviations caused by manufacturing errors or attachment variations, ensuring reliable connection while maintaining the ability to supply large volumes of ink through the intermediate tank configuration
Solution Approach 2:
The position adjusting unit changes the positional parameter of the liquid container along the connecting direction. By providing adjustable positioning mechanisms, the system can compensate for manufacturing tolerances and attachment errors, maintaining connection reliability despite the large size of the intermediate ink tank
2Ease of operation
If the liquid container is moved along the connecting direction to connect to the connection unit, then the connection is established, but position deviation occurs due to manufacturing and attachment errors
Solution Approach 1:
The position adjusting unit provides dynamic position adjustment capability along the connecting direction, allowing the liquid container to be precisely positioned during connection. This dynamic adjustment compensates for manufacturing and attachment errors, ensuring reliable connection establishment while maintaining position accuracy
3Manufacturing precision
If the position of the liquid container is adjusted in the connecting direction, then connection alignment is improved, but no compensation is provided for positional deviations in directions intersecting the connecting direction
Solution Approach 1:
The patent extends the position adjustment capability from only the connecting direction to include directions intersecting with the connecting direction. This multi-dimensional adjustment capability allows comprehensive compensation for position deviations, improving both connection alignment and overall adaptability to manufacturing and attachment variations

Function Achieved in This Case
This configuration enables precise, stepless adjustment of the liquid container's position, ensuring stable connections and preventing leakage by supporting the container's weight and allowing for accurate alignment, even with manufacturing errors, thus enhancing operational reliability.
Implementation Method 1
the position adjusting unit may include a rotating member which configures a screw pair, and the liquid container may move in the direction which intersects the connecting direction along with rotating of the rotating member
