Ink Tank-Based Ink Bottle Tracking for Printer Reordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to order ink bottles for inkjet printers at appropriate timing, leading to potential ink shortages or wastage due to insufficient or depleted ink supplies.
Innovation Solution
A recording apparatus equipped with a determination unit to assess ink consumption in both the ink tank and bottle, transmitting information to a server when a predetermined threshold is reached, enabling timely ordering of ink bottles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ink consumption is monitored only in the ink tank (not the ink bottle), then the monitoring system is simple, but ink bottles may be ordered at inappropriate timing (either too early with sufficient ink or too late when already depleted)
Solution Approach 1:
The system performs preliminary action by calculating the ink consumption amount in the ink bottle in advance based on the ink consumption amount in the ink tank. This allows the system to determine when to order ink bottles before actual depletion occurs, preventing both premature ordering and running out of ink. The determination unit computes the bottle consumption from tank consumption data, enabling proactive ordering decisions.
Solution Approach 2:
The patent introduces an intermediary calculation approach where the ink consumption in the ink bottle is not directly measured but inferred through the relationship between ink tank consumption and ink bottle consumption. The determination unit acts as an intermediary that translates tank-level monitoring data into bottle-level consumption estimates, enabling accurate monitoring without direct bottle sensors.
2Reliability
If continuous communication between recording apparatus and server is maintained, then real-time ink status can be monitored, but communication load increases
Solution Approach 1:
The system implements periodic action by transmitting ink consumption information to the server only when the predetermined threshold value is reached, rather than continuously. The transmission unit monitors the calculated ink bottle consumption and initiates communication only at critical moments when ordering should be considered, reducing unnecessary data transmission while maintaining reliable monitoring.
Solution Approach 2:
The recording apparatus performs self-service by autonomously determining when ink bottle ordering is needed based on its own consumption calculations. The determination unit independently assesses ink status and triggers transmission only when the threshold is met, eliminating the need for continuous server queries or manual user checks, thus reducing communication overhead while maintaining system reliability.

AI summary
A recording apparatus including an ink tank storing ink supplied from an ink bottle and a head to which ink is supplied from the ink tank includes a determination unit configured to determine a value related to ink consumption in the ink bottle based on a value related to ink consumption in the ink tank, and a transmission unit configured to transmit information indicating the value related to the ink consumption in the ink bottle to a server in a case where the value related to the ink consumption in the ink bottle reaches a predetermined threshold value, and performs processing of ordering of a new ink bottle based on the amount of ink consumed in the ink bottle.
