Inkjet Recording Apparatus Ink Refill Confirmation Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet recording apparatuses fail to accurately determine when ink chambers are empty due to incorrect initialization of count values when users repeatedly input 'YES' without refilling, leading to air entering the recording head and improper ink ejection.
Innovation Solution
An inkjet recording apparatus with a controller that performs an inquiry process, displaying a confirmation screen and requiring a specific operation to confirm ink refilling, ensuring accurate initialization of count values only after valid refilling confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inkjet recording apparatus initializes count values in response to repeated 'YES' inputs during the inquiry process, then the user operation processing is simplified, but the measurement precision of ink chamber empty state detection deteriorates
Solution Approach 1:
The system performs preliminary actions by displaying confirmation screens and requiring specific operation patterns before initializing count values. This preliminary verification process ensures that repeated 'YES' inputs are genuinely intended by the user rather than accidental or erroneous inputs, thereby maintaining measurement precision while still providing ease of operation for legitimate refilling confirmations.
Solution Approach 2:
The system implements feedback mechanisms by monitoring operation patterns and providing visual confirmation through display screens. The controller tracks whether operations match expected patterns for refilling confirmation, and only initializes count values when the feedback indicates genuine user intent. This feedback loop resolves the contradiction by ensuring accurate detection while maintaining operational simplicity.
2Measurement precision
If the inkjet recording apparatus requires multiple confirmation steps for ink refilling, then the measurement precision of ink chamber empty state detection is improved, but the device complexity increases
Solution Approach 1:
The system employs dynamic operation patterns where the confirmation process adapts based on detected user actions. Rather than requiring fixed multiple steps for all cases, the inquiry process dynamically adjusts based on whether operations match expected refilling patterns, reducing unnecessary complexity while maintaining precision for genuine refilling scenarios.
Solution Approach 2:
The system changes operational parameters by monitoring operation patterns and using these changes to determine whether to proceed with count value initialization. The parameter change from simple input detection to pattern-based verification improves measurement precision without permanently increasing device complexity, as the additional verification logic is triggered only when needed.
3Device complexity
If the inkjet recording apparatus uses simple operation recognition for ink refilling confirmation, then the device complexity is reduced, but the reliability of ink chamber state monitoring deteriorates
Solution Approach 1:
The system uses self-service by leveraging the user's own operation patterns as the verification mechanism. The inquiry process monitors whether operations follow expected patterns for refilling confirmation, using the user's deliberate actions themselves as the reliability check rather than requiring external sensors or complex verification systems. This maintains low device complexity while improving reliability.
Solution Approach 2:
The system performs preliminary monitoring of operation patterns before finalizing ink chamber state changes. By checking whether operations match expected refilling patterns in advance, the system ensures reliable state monitoring without requiring complex real-time verification mechanisms, thus maintaining low device complexity while improving reliability.

AI summary
An inkjet recording apparatus includes: a tank; a recording head; a display; an operation interface; a memory; and a controller. The controller performs: an inquiry process in which a displaying and receiving process is repeatedly performed for each of ink chambers of the tank to inquire whether ink has been injected into a target ink chamber; an operation determination process to determine whether all of operations received in the inquiry process are first operations; and, in response to the determination in the operation determination process that all of the operations received in the inquiry process are first operations, a confirmation process to prompt a user to input a third operation to confirm that ink has been injected into all of the ink chambers. The controller initializes, in response to receipt of the third operation in the confirmation process, count values for all of the ink chambers.
