Imaging Cartridge Chip Dual-Accuracy Volume Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face challenges in accurately determining the remaining consumable volume in different types of imaging cartridges, leading to misjudgments about the number of printable pages, resulting in premature or inadequate replacement of cartridges.
Innovation Solution
The implementation of an imaging cartridge chip that stores and manages two levels of consumable volume information: a more accurate first consumable volume information and a less accurate second consumable volume information, using an algorithm to generate and update the second information for timely reminders and accurate printing control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high accuracy consumable volume information is stored in the chip, then the remaining consumable volume can be determined accurately, but the chip storage capacity is insufficient to store both high accuracy and low accuracy information
Solution Approach 1:
The consumable volume information is segmented into two distinct accuracy levels: first consumable volume information with higher accuracy and second consumable volume information with lower accuracy. This segmentation allows the chip to store multiple types of information with different precision requirements, optimizing both storage utilization and information quality for different application scenarios.
Solution Approach 2:
Different regions or uses of the stored data have different quality requirements. The first consumable volume information is used when high precision is needed (e.g., for locking decisions), while the second consumable volume information is used for general display and user awareness. This local quality differentiation resolves the contradiction by matching information accuracy to specific functional needs rather than uniformly high accuracy throughout.
2Ease of operation
If the same standard is used to indicate remaining consumable volume for different imaging cartridge types, then the system is simple to operate, but user misjudgment occurs on the number of printable pages
Solution Approach 1:
The system changes the parameter of consumable volume information accuracy based on the specific imaging cartridge type and its printable page capacity. For cartridges with different total page yields, the system adjusts whether to use first or second consumable volume information, transforming a static indication system into a dynamic one that adapts to different cartridge characteristics.
Solution Approach 2:
The consumable volume indication system becomes dynamic by switching between first consumable volume information (higher accuracy) and second consumable volume information (lower accuracy) based on the imaging cartridge type. This dynamic adjustment ensures that users receive appropriately calibrated information for their specific cartridge, preventing misjudgment while maintaining operational simplicity.

AI summary
A method for responding to read/write consumable volume information in an imaging device. The method includes: receiving first consumable volume information from the imaging device and storing the received first consumable volume information; receiving second consumable volume information from the imaging device; obtaining, by the imaging cartridge chip, the first consumable volume information and transmitting the first consumable volume information to the imaging device when the imaging device requests reading consumable volume information stored in the imaging cartridge chip for determining a remaining consumable volume in an cartridge; obtaining, by the cartridge chip, the second consumable volume information and transmitting the second consumable volume information to the imaging device when the imaging device requests reading consumable volume information stored in the imaging cartridge chip to indicate the remaining consumable volume in the cartridge, the second consumable volume information being less accurate than the first consumable volume information.
