Printing Cartridge Identification Portion for Efficient Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing systems require separate reading of information from the memory in the circuit substrate and labels on cartridges, leading to inefficiencies in authentication and operation control, as these components are distinct and need to be read individually.
Innovation Solution
A printing system that includes a printing material cartridge with an identification portion recording identification information, a printing apparatus with an apparatus reading portion to optically read this information, and a compatibility determination portion to assess cartridge compatibility, along with a portable terminal for displaying the identification information, allowing for integrated reading and display of essential data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate memory and label components are used on the cartridge, then information can be stored and displayed, but the reading process becomes inefficient and requires multiple separate reading operations
Solution Approach 1:
The patent combines the memory component and label into a single integrated identification portion on the cartridge. This identification portion contains both machine-readable information (for authentication) and visually displayable information (for user reference), eliminating the need for separate memory and label components while enabling simultaneous reading of all cartridge information through a single optical reading operation.
2Ease of operation
If information is stored in separate memory and label components, then data can be accessed by different devices, but the authentication and operation control processes become more complex
Solution Approach 1:
The integrated identification portion serves multiple functions simultaneously: it stores machine-readable information for authentication by the printing apparatus, provides visually displayable information for user reference, and enables both functions through a single unified structure. This multi-functional design simplifies the authentication and operation control processes while reducing information structure complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution streamlines the authentication and operation control process by enabling the printing system to read and display identification information from the cartridge's identification portion, reducing the need for separate memory and label components, thus enhancing efficiency and user convenience while promoting environmental sustainability by allowing for easier reuse of cartridges.
Implementation Method 1
an apparatus reading portion that is formed inside the cartridge mounting portion and optically reads the identification portion

AI summary
A printing system includes: a printing material cartridge that accommodates a printing material and has an identification portion on which identification information for identifying the printing material cartridge is recorded; a printing apparatus including a cartridge mounting portion in which the printing material cartridge is mounted, and an apparatus reading portion that is formed inside the cartridge mounting portion and optically reads the identification portion; a compatibility determination portion that determines whether or not the printing material cartridge is compatible with the cartridge mounting portion by using the identification information obtained by reading the identification portion with the apparatus reading portion; and a portable terminal including a terminal display portion that displays the identification information obtained by reading the identification portion.
