Maintenance Unit Visible Recording Target Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance units for liquid ejecting apparatuses, such as inkjet printers, require powering on and reattachment to retrieve information about their usage and validity, which is time-consuming and inefficient.
Innovation Solution
A maintenance unit with a recording target section that allows information about its usage, validity, and attachment history to be recorded in a visibly recognizable manner, enabling retrieval of this information without reattachment to the liquid ejecting apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the maintenance unit is detached from the liquid ejecting apparatus, then the maintenance unit can be stored or exchanged, but the information about usage and validity cannot be accessed without reattachment and power-on
Solution Approach 1:
The patent creates a visible copy of the information stored in the storage element by having the liquid ejecting section record the usage information and validity date onto a recording target section of the maintenance unit. This copy can be read visually or with a scanner without requiring the maintenance unit to be attached to the apparatus or the apparatus to be powered on, thus resolving the contradiction between information accessibility and time loss.
2Loss of information
If the waste liquid cartridge is exchanged frequently to check information, then information about usage can be obtained, but operational efficiency decreases
Solution Approach 1:
The visible recording of usage information and validity dates on the recording target section eliminates the need to exchange or reattach the maintenance unit to check information. Users can simply visually inspect or scan the recorded information, maintaining operational efficiency while still accessing usage information.
3Reliability
If the maintenance unit stores information internally in a storage element, then information can be preserved, but the information cannot be accessed without specific operations (power-on and reattachment)
Solution Approach 1:
The patent preserves the reliability of internal storage while improving ease of operation by creating a visible copy of the stored information on the recording target section. This allows users to access information through simple visual inspection or scanning without requiring power-on or reattachment operations, thus resolving the contradiction between information preservation and ease of access.
