Inkjet Line Head Replacement Using Unused Waste Ink Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inkjet recording apparatuses waste unused recording heads and waste ink collection containers, leading to inefficient use of components and installation space.
Innovation Solution
Incorporation of a conveyance portion, line heads, waste ink collection containers, a display portion, and a control portion to detect and indicate unused recording heads and waste ink collection containers for replacement, allowing their effective use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum number of colors available for use is larger than the number of colors actually used, then more recording heads and waste ink collection containers are installed, but unused recording heads and waste ink collection containers are left without being used, wasting components and installation space
Solution Approach 1:
The patent makes unused recording heads and waste ink collection containers multi-functional by enabling them to replace used components when needed. The control portion detects component states and guides users to replace used recording heads or waste ink containers with unused ones, allowing the same physical components to serve different functions at different times, thus eliminating waste while maintaining adaptability.
Solution Approach 2:
Instead of discarding unused recording heads and waste ink collection containers, the system recovers their potential utility by implementing a state-detection and replacement guidance mechanism. The control portion monitors component usage states and prompts users to swap unused components into active positions, effectively recovering the value of previously idle components.
2Area of stationary object
If unused recording heads and waste ink collection containers are left without being used, then component installation space is occupied, but the components themselves are wasted
Solution Approach 1:
The patent enables unused recording heads and waste ink collection containers to transition from idle storage to active service roles. By implementing a replacement guidance system, the same installation space can accommodate different component configurations based on actual usage needs, maximizing both space utilization and component effectiveness.
3Productivity
If replacement of recording heads or waste ink collection containers is needed, then downtime occurs, but unused components are not utilized for replacement
Solution Approach 1:
The system performs preliminary detection of component states and proactively guides users to perform replacements before critical failures occur. By monitoring usage states and providing replacement guidance, the system enables users to swap components during planned maintenance rather than during unexpected failures, reducing unplanned downtime.
Solution Approach 2:
The control portion continuously detects component states and provides feedback to users about which components need replacement. This feedback mechanism enables informed decision-making about component replacement timing and selection, allowing users to utilize unused components effectively and minimize operational disruptions.

AI summary
The inkjet recording apparatus includes a plurality of line heads each including a recording head, a plurality of waste ink collection containers, a display portion that indicates states of the line heads and the waste ink collection containers, and a control portion that detects the states of the line heads and the waste ink collection containers and controls display portion. In a case where an unused line head or an unused waste ink collection container exists and where a recording head in one of the line heads in use or one of the waste ink collection containers in use needs to be replaced, the control portion indicates, on the display portion, the recording head in the unused line head or the unused waste ink collection container as a recording head available for replacement or a waste ink collection container available for replacement.
