Liquid Supply Device with Selectable Paths for Ink Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supply devices for printers are not effectively utilized as refill containers, as they lack the ability to select and supply appropriate ink based on the type of cartridge and detect low ink levels, leading to inefficient ink management.
Innovation Solution
A liquid supply device with multiple liquid supply paths, detectors, and a selector that identifies the type of cartridge and supplies the corresponding ink, while also detecting low ink levels and notifying the user or administrator for refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single liquid supply path is used, then the device structure is simple, but the adaptability to different container types is poor
Solution Approach 1:
The liquid supply device is divided into multiple independent liquid supply paths (first liquid supply path, second liquid supply path, etc.), each corresponding to a specific container type. This segmentation allows the device to handle different container types through dedicated paths while maintaining overall system organization and manageability.
Solution Approach 2:
The liquid supply device incorporates multiple liquid supply paths that can each serve different container types, making the device universally applicable to various container configurations. The selector mechanism enables the device to adapt its function based on the inserted container type, achieving multi-functionality.
2Productivity
If ink supply is not monitored, then the device operation is simple, but the ink management efficiency is poor
Solution Approach 1:
The device incorporates detectors that continuously monitor the ink storage amount in real-time and provide feedback to the control unit. When the ink level reaches a predetermined lower limit, the control unit receives this feedback and issues notifications to users, enabling proactive ink management and preventing supply interruptions.
Solution Approach 2:
The detector monitors ink levels in advance and notifies users before the ink is completely depleted. This preliminary action allows users to refill ink proactively, avoiding printing interruptions and improving overall ink management efficiency.
3Manufacturing precision
If the liquid supply path is not selectable, then the device structure is simple, but the precision of ink type matching is poor
Solution Approach 1:
The device incorporates a selector mechanism that dynamically switches between different liquid supply paths based on the container type inserted. This dynamic selection ensures that the correct ink type is supplied to the corresponding container, achieving precise matching while allowing the device to adapt to different configurations.

AI summary
A liquid supply device includes a first liquid supply path that supplies ink to a first liquid supply port corresponding to a cartridge, a second liquid supply path that supplies ink in a second liquid container to a second liquid supply port corresponding to a cartridge, a selector that selects either the first liquid supply path or the second liquid supply path, an on-off valve and a pump that, when the first liquid supply path is selected by the selector, supplies ink via the first liquid supply path to the cartridge, and an on-off valve and the pump that, when the second liquid supply path is selected by the selector, supplies ink via the second liquid supply path to the cartridge.
