Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink supplying apparatuses risk ink adhering to the tank connection area and flowing down the outer surface, leading to dirtiness of the apparatus.
Innovation Solution
A liquid supplying apparatus design featuring a liquid container with a circular wall and a tank recessed part, where the circular wall is inserted into the tank recessed part, and a communicating tube connects the liquid container to the tank, ensuring the liquid flows into the tank without adhering to the outer surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid container is connected to the tank from thereabove with the air introducing part communicating with the atmosphere, then the liquid surface can be maintained constant, but the liquid may adhere to the connection part and flow down along the outer circumferential surface causing dirtiness
Solution Approach 1:
The patent introduces a guide member as an intermediary component between the liquid container and the tank. This guide member has a guide hole through which the communicating tube passes, and the guide hole is positioned to direct the liquid flow away from the outer circumferential surface of the tank. The guide member acts as a mediator that redirects the liquid path, preventing direct contact between the liquid and the tank's outer surface while maintaining the functional connection.
Solution Approach 2:
The patent changes the spatial arrangement by positioning the guide hole and communicating tube in a specific three-dimensional configuration. The guide hole is formed to direct liquid flow along a predetermined path that moves the liquid away from the problematic outer circumferential surface area. This dimensional repositioning of the flow path prevents liquid adhesion to the tank exterior while maintaining the air introduction and liquid supply functions.
2Productivity
If the communicating tube is positioned to allow liquid flow from the liquid container to the tank, then liquid supply is enabled, but liquid may adhere to the connection area and flow down the outer surface
Solution Approach 1:
The guide member serves as an intermediary structure that receives the communicating tube and directs its output. The guide hole within the guide member intercepts the liquid flow from the communicating tube and redirects it along a controlled path that avoids the outer circumferential surface of the tank. This intermediary structure maintains efficient liquid supply while eliminating the adhesion problem.
Solution Approach 2:
The patent applies local quality by creating a specific flow direction in the local area where liquid exits the communicating tube. The guide hole is designed with a specific orientation and shape that channels liquid flow in a predetermined direction, ensuring that liquid is directed away from the outer circumferential surface only in the critical connection area, while other areas of the tank remain unaffected.
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
Prevents ink from flowing down the outer surface of the tank, maintaining cleanliness and preventing dirt accumulation.
Implementation Method 1
the communicating tube has a first channel and a second channel communicating the storing chamber with outside
Implementation Method 2
the liquid flows out from the internal space of the liquid container to the storing chamber of the tank
Implementation Method 3
The tank is provided with an air introducing part communicating with the atmosphere. In a case that the ink inside the tank is consumed and that the liquid surface of the ink becomes to be lower than a forward end part of the air inflow pipe, the air enters from the air introducing part into the tank

AI summary
There is provided a liquid supplying apparatus including: a liquid container including an internal space, and a tank having a storing chamber. The liquid container has: an upper surface, a nozzle, and a circular wall projecting upward from the upper surface. The tank has: a body; a projecting wall defining a tank recessed part, and a communicating tube positioned in the tank recessed part and having first and second channels which communicate the storing chamber with outside. The circular wall is inserted into the tank recessed part, and the communicating tube is inserted into the opening of the nozzle so as to allow the liquid to flow out from the internal space to the storing chamber. In a case that the liquid container is connected to the tank, the circular wall is positioned inside the projecting wall.
