Solution Overview

Problem

In traditional ink cartridges, different thicknesses of second signal blocking sections lead to ink cartridge installation errors, causing printers to detect incorrect information about the ink cartridges.

Innovation Solution

The ink cartridge features a movable second signal blocking section with an initial ink cartridge installation detection position that determines whether it blocks or changes the path of the second signal, allowing for accurate detection and preventing errors due to varying thicknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different thicknesses of second signal blocking sections are used to distinguish different ink cartridges, then ink cartridge identification is enabled, but ink cartridge installation errors occur more frequently

Engineering Contradiction:

Improveink cartridge identification capabilityVSAvoidinstallation accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The second signal blocking section is designed as a movable component that can shift position based on ink cartridge installation. The movable member transitions between blocking and non-blocking states of the second signal, enabling dynamic identification while maintaining consistent physical dimensions across all cartridges, thus preventing installation errors.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Instead of varying the physical thickness of the second signal blocking section, the invention changes the signal blocking parameter dynamically through the movable member's position. The movable member blocks or unblocks the second signal based on installation detection, providing cartridge identification without requiring different thicknesses.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the second signal blocking section is made movable to enable accurate detection, then installation errors are reduced, but device complexity increases

Engineering Contradiction:

Improveinstallation detection accuracyVSAvoidsignal blocking section structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The signal blocking function is segmented into two independent components: a fixed first signal blocking section and a movable second signal blocking section with a movable member. This segmentation allows the second signal blocking section to provide dynamic detection capability while the first section maintains stable signal blocking, reducing overall system complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The movable member automatically transitions between blocking and non-blocking positions based on the ink cartridge installation state, without requiring external control mechanisms. The system self-regulates the signal blocking state according to installation detection, simplifying the control structure.

Inventive Principle:

Principle #25Self-service

AI summary

The invention relates to an ink cartridge, an ink cartridge set and an ink cartridge determination system. The invention comprises a first signal blocking section and a second signal blocking section, wherein the second signal blocking section is a movable component and is in an initial ink cartridge installation detection position before detection, and the initial ink cartridge installation detection position determines whether or not the second signal blocking section prevents a second signal from passing through the second signal blocking section or changes the path of the second signal. That is to say, different ink cartridges can be distinguished by different initial ink cartridge installation detection positions of the movable second signal blocking section.
