Solution Overview

Problem

Existing imaging devices may continue to perform operations when imaging materials are almost depleted, leading to potential device failures due to empty prints and shortened service life.

Innovation Solution

A memory chip for imaging cartridges with a service life determining unit and exception processing capabilities, which determines the remaining usage of print materials and, when depleted, performs exception processing to prevent further imaging operations by either skipping or incorrectly responding to instructions from the imaging device, thereby stopping the imaging process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the imaging device continues to perform imaging operations when imaging materials are almost depleted, then the productivity is maintained, but the reliability deteriorates due to potential device failures and shortened service life

Engineering Contradiction:
Improveimaging operation continuityVSAvoiddevice service life
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The memory chip performs preliminary detection of imaging material levels and proactively sends abnormality indication signals before the materials are completely depleted. This preliminary action prevents the device from attempting operations with insufficient materials, thereby avoiding damage and extending service life while maintaining productivity during the usable period

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback mechanism where the memory chip continuously monitors imaging material levels and communicates status information to the imaging device. When materials are depleted, the memory chip sends abnormality indication signals that trigger the device to stop operations, creating a closed-loop control system that prevents reliability deterioration

Inventive Principle:
Principle #23Feedback

2Reliability

If the imaging device stops imaging operations when materials are depleted, then the reliability is improved by avoiding device failures, but the productivity deteriorates due to interruption of imaging operations

Engineering Contradiction:
Improvedevice service lifeVSAvoidimaging operation continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary detection and notification before material depletion occurs. By sending abnormality indication signals in advance, the system allows users to prepare for material replacement without sudden interruptions, thereby improving reliability while minimizing productivity impact

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The memory chip autonomously monitors material levels and manages communication with the imaging device without external intervention. This self-service capability ensures reliable operation cessation when needed while maintaining productivity during normal operation through automated status tracking

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the memory chip accurately detects and reports imaging material levels, then the measurement precision is improved, but the device complexity increases due to additional monitoring and communication mechanisms

Engineering Contradiction:
Improvematerial level detection accuracyVSAvoidmemory chip structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the detection, storage, and communication functions into a single integrated memory chip unit. This consolidation achieves precise material level detection and reporting while avoiding the complexity of separate monitoring systems, as the memory chip naturally stores material level data and can communicate it through existing interfaces

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The memory chip serves multiple functions: storing imaging material level information, detecting material depletion status, and communicating with both the imaging device and external terminals. This multi-functionality achieves precise monitoring without adding dedicated complex hardware, as the same chip handles multiple tasks

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention discloses an imaging cartridge and a memory chip applied to the imaging box, so as to overcome a disadvantage that when available usage of imaging materials reaches a preset threshold, an existing imaging device may still continue to perform an imaging operation to easily cause a device failure. The memory chip is detachably installable on an imaging box, and the imaging box is detachably installable in the imaging device. The memory chip includes: an interface unit, electrically connecting the memory chip to the imaging device, and receiving an instruction that is sent from the imaging device; a storage unit, storing information related to the imaging box; a service life determining unit, determining, according to the information that is related to the imaging box and that is stored in the storage unit, whether a service life of the imaging box runs out; and an exception processing unit, performing, when the service life determining unit determines that the service life of the imaging box runs out, exception processing according to the instruction sent by the imaging device. By means of the present invention, occurrence of a phenomenon that when imaging materials in an imaging box may run out, a failure occurs in an imaging device due to an empty print can be effectively avoided.
