Printing Apparatus Ink Delivery Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses face challenges in timely delivery of liquid containers, such as ink bottles, as they often run out of ink before a new container can be replenished, leading to inefficient ink usage and potential printing disruptions.
Innovation Solution
A printing system that communicates with a server to monitor ink consumption, request delivery of liquid containers earlier than estimated completion, and adjusts initial values based on authentication of new containers to ensure accurate tracking and timely replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printing apparatus waits until the liquid accommodation body is empty before requesting delivery, then the liquid container can be delivered when needed, but the printing apparatus may run out of liquid and printing is disrupted
Solution Approach 1:
The printing apparatus requests delivery of a new liquid container before the current one is completely consumed. The control unit calculates remaining liquid amount and initiates delivery requests in advance, ensuring the new container arrives before the old one is empty, thus preventing printing disruption while optimizing delivery timing.
2Reliability
If the printing apparatus requests delivery early, then printing disruption is prevented, but the liquid container may be delivered too early causing liquid waste
Solution Approach 1:
The control unit continuously monitors the remaining liquid amount in the liquid accommodation body and adjusts delivery request timing based on this feedback. By calculating consumption rates and tracking remaining levels, the system optimizes delivery timing to arrive just before depletion, preventing both printing disruption and excessive liquid waste from premature delivery.
Solution Approach 2:
The delivery request timing is dynamically adjusted based on real-time liquid consumption patterns. The control unit modifies delivery schedules according to actual usage rates, ensuring optimal timing that prevents both early delivery waste and late delivery disruptions.
3Measurement precision
If the counting section does not reset upon authentication, then consumption tracking continues seamlessly, but the accuracy of consumption counting deteriorates
Solution Approach 1:
The control unit resets the consumption counting to the initial value upon authentication of a new liquid container. This preliminary reset action ensures accurate tracking of the new container's consumption from the start, while the system maintains continuity by managing multiple counting cycles across different containers.

AI summary
A printing apparatus includes a liquid accommodation body into which liquid contained in a liquid container is configured to be poured, a printing section that performs printing by discharge of liquid supplied from the liquid accommodation body, a counting section that performs counting relating to an amount of consumption of liquid with which a liquid container was contained and counting relating to an amount of consumption of liquid per predetermined period of time, and a delivery request section that, based on a counting result yielded by the counting section, sends the server apparatus a delivery request for a liquid container by a time that is earlier by a delivery period of a liquid container than an estimated timing of completion of consumption of liquid with which a liquid container was contained.
