Rotatable Handle Ink Container for Easy Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supply apparatuses for inkjet printers face difficulties in visually confirming and easily attaching/detaching ink bags due to the positioning of the connection section, leading to challenges in handling and potential damage.
Innovation Solution
A liquid container design with a flexible liquid containing section, a protruding base member, a rotatable handle section, and engagement mechanisms that allow easy attachment and detachment, along with visual confirmation of the liquid extraction section, facilitating connection to the supply apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection section is positioned on the lower side of the ink bag in the vertical direction, then the liquid supply function is achieved, but the connection section becomes difficult to visually confirm and handle
Solution Approach 1:
The connection section is repositioned from a vertical lower position to a horizontal protruding position on the base member. This dimensional change allows the connection section to be visible from the side when the container is held by the handle, resolving the contradiction between accessibility and visibility.
Solution Approach 2:
The base member serves as an intermediary structure that extends beyond the liquid containing section to provide a accessible platform for the connection section. This intermediary structure allows the connection section to be both functionally positioned and visually accessible.
2Ease of operation
If the liquid containing section is made flexible to facilitate attachment and detachment, then the ease of operation is improved, but the risk of damage to the liquid containing section increases
Solution Approach 1:
The liquid container is segmented into distinct functional parts: the flexible liquid containing section for holding liquid, the rigid base member for structural support and connection, and the rotatable handle section for operation. This segmentation allows each part to be optimized for its specific function, with the base member protecting the flexible containing section during handling.
Solution Approach 2:
The base member acts as a protective cushioning structure that shields the flexible liquid containing section from mechanical damage during attachment, detachment, and handling operations, preventing direct exposure to stress.
3Ease of operation
If the handle section is made rotatable to improve handling ease, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The handle section is designed with rotational capability, transforming it from a static to a dynamic component. This allows the handle to adapt its orientation during handling operations, improving ease of operation while maintaining relatively simple structure through the rotation mechanism.

AI summary
An ink container, which is able to be attached to and detached from a liquid supply apparatus which supplies liquid to a liquid ejecting apparatus, provided with an ink containing section which has flexibility and which contains the ink, a base member which is positioned on an end section of the ink containing section and which protrudes more to the outer side than the ink containing section, an ink extraction section which is provided in the base member and which forms a flow path which is linked with an inner section of the ink containing section via the base member, and a handle which is provided so as to be able to be rotated with regard to the base member.
