Solution Overview

Problem

In liquid ejecting systems, users face a heavy workload when checking ink levels due to the need to move laterally to observe the ink tank from the side opposite the printer, especially in wide printers, making the process cumbersome.

Innovation Solution

A liquid ejecting system design where the liquid storing container is movable relative to the liquid ejecting apparatus, allowing the user to visually inspect the container's interior from a more convenient angle, reducing the need for lateral movement and improving operational efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the checking window is provided in the side face opposite to the liquid ejecting apparatus, then the liquid storing container can be checked for liquid level, but the user must move laterally to observe, increasing workload

Engineering Contradiction:
Improveliquid level checkabilityVSAvoiduser workload
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The tank unit is made movable relative to the printer body through a guide mechanism, allowing it to be pulled out to a checking position where the checking window becomes easily accessible to the user without requiring lateral movement

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The checking window is positioned on the side face of the tank unit that faces the printer, and the tank unit is moved along the width direction to bring this checking window within the user's observation range, transforming the observation geometry

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the printer width is large, then the liquid ejecting apparatus can accommodate more components, but the user must move outward to check the liquid level, increasing operation complexity

Engineering Contradiction:
Improveprinter widthVSAvoidchecking operation simplicity
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The tank unit is designed to be movable along the width direction of the printer, allowing users to pull it out to a position where the checking window is within easy observation range, regardless of the printer's overall width

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A guide mechanism serves as an intermediary structure that enables smooth movement of the tank unit between the operating position and the checking position, facilitating easy access to the checking window

Inventive Principle:
Principle #24Intermediary (Mediator)
