Liquid Ejecting System Identifier Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a risk that users may inadvertently use liquid containers outside the coverage of their specific service plan, leading to potential issues such as nozzle clogging and unexpected liquid usage in liquid ejecting apparatuses, as existing techniques lack effective identification and verification methods to ensure compatibility between liquid containers and the apparatuses they are intended for.
Innovation Solution
A liquid ejecting system that includes a specific liquid ejecting apparatus with a first identifier indicating service plan coverage and a specific liquid container with a second identifier, where the apparatus acquires the second identifier and compares it with the first identifier to determine usability, ensuring that only compatible liquid containers are used, with the second identifier including information related to the first identifier for easy differentiation.

Engineering Contradiction Analysis
1Reliability
If no identifier verification system is implemented, then users have freedom to choose any liquid container, but incompatible containers may be used causing nozzle clogging and service plan violations
Solution Approach 1:
The patent applies preliminary action by equipping liquid containers with identifiers (such as IC tags or barcodes) before they are used in the ejecting apparatus. This pre-established identification system allows the apparatus to verify container compatibility in advance through acquisition and comparison of identifiers, preventing incompatible containers from being used and thus ensuring reliability without requiring complex real-time monitoring systems.
2Reliability
If identifier acquisition and comparison functions are added to the ejecting apparatus, then container compatibility is verified, but the apparatus structure becomes more complex
Solution Approach 1:
The patent applies self-service by enabling the liquid container itself to carry and present its identification information through integrated IC tags or barcodes. The container essentially identifies itself to the apparatus, which then performs a simple comparison operation. This approach minimizes the complexity of the apparatus structure while ensuring service plan adherence, as the verification burden is shifted to the container's own identification system rather than requiring complex verification hardware in the apparatus.
3Ease of operation
If simple identifier comparison is used, then the verification process is quick and simple, but detailed container information cannot be verified
Solution Approach 1:
The patent applies the nested doll principle by implementing a hierarchical identifier structure where basic identification information (such as service plan type) is contained in outer identifier layers, while more detailed information (such as container specifications and compatibility data) is nested within inner identifier layers. This allows the verification process to first perform quick basic checks and then access detailed information only when needed, maintaining ease of operation while achieving high verification accuracy through multi-level identifier comparison.

AI summary
A liquid ejecting system includes a specific liquid ejecting apparatus having a first identifier indicative of coverage by a specific service plan, and a specific liquid container having a second identifier indicative of coverage by the specific service plan. The specific liquid ejecting apparatus includes an acquisition section that acquires the second identifier, and a determination section that compares the first identifier with the acquired second identifier and determines whether the specific liquid container is usable for the specific liquid ejecting apparatus.
