Liquid Supply Connection Structure on Outer Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supply devices for liquid-consuming apparatuses, such as printers, face challenges in easily connecting and disconnecting liquid lead-out and introduction portions due to their submerged configuration, leading to difficulties in observation and attachment, which affects usability and efficiency.
Innovation Solution
A liquid supply device with a liquid supply connection structure supported on the outer wall of the apparatus, facilitating easier connection and providing a larger space for the liquid container, reducing vaporization, and incorporating a protective member to prevent contamination, with visible electrical connections for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid supply connection structure is placed inside the liquid consuming apparatus, then the connection is protected, but the liquid container cannot be easily observed and attached
Solution Approach 1:
The patent inverts the conventional configuration by placing the liquid supply connection structure on the outer wall of the liquid consuming apparatus rather than inside. This allows the liquid container to be easily observed and attached from the outside while the connection structure remains protected through a protective member that can be opened during connection and closed during operation
2Ease of operation
If the liquid supply connection structure is placed on the outer wall, then the liquid container is easily observed and attached, but the connection may be exposed to contamination
Solution Approach 1:
The patent segments the connection system into two parts: the liquid supply connection structure on the outer wall for easy access, and a protective member that can be opened during connection and closed during operation. This segmentation allows the connection to be easily accessible while protecting it from contamination during use
Solution Approach 2:
The protective member is preliminarily positioned to cover the liquid supply connection structure before connection occurs. This preliminary protection prevents contamination before the connection is made, and the protective member is then opened to allow connection, after which it can be closed again to restore protection
