Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic reset methods for consumable chips require manual user intervention, are prone to errors, and involve complex hardware modifications, leading to instability and increased costs due to power supply issues during the resetting process.
Innovation Solution
An automatic reset method for consumable chips that utilizes software control to manage the reset process without additional hardware, ensuring stable operation and low costs by shielding printer commands and using a non-volatile storage module to maintain configuration parameters, allowing for efficient ink amount data reset without altering the original circuit structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switch device operation is used to control reset, then the chip can determine whether to perform reset operation, but the manual operation is inconvenient and error-prone
Solution Approach 1:
The chip automatically detects its own ink-out state and performs reset operations without requiring manual user intervention. The control module monitors ink consumption and autonomously initiates the reset process when the ink is depleted, eliminating manual errors and improving convenience.
Solution Approach 2:
The patent replaces manual mechanical switch operations with software-based automatic detection and control. The control module uses firmware to monitor ink levels and trigger reset sequences, substituting physical user actions with automated electronic control.
2Extent of automation
If switch device connection and disconnection is used to control reset, then the chip can perform reset operation, but the load changes affect the stability of working state and service life of electrical components
Solution Approach 1:
The control module detects the ink-out state in advance and prepares the reset operation before actual ink depletion occurs. This preliminary detection allows the system to initiate reset sequences proactively, avoiding sudden circuit load changes and maintaining stability.
Solution Approach 2:
The patent implements dynamic control of the reset process through the control module, which continuously monitors ink levels and adjusts the timing of reset operations. This dynamic approach prevents abrupt circuit state changes by smoothly transitioning between operational modes.
3Extent of automation
If additional hardware such as power supply device is added to support automatic reset, then the chip can run during resetting, but the circuit structure becomes complex and cost increases
Solution Approach 1:
The control module serves multiple functions: it monitors ink levels, detects ink-out states, manages reset operations, and maintains power management. By consolidating these functions into a single multi-functional module, the patent avoids adding separate dedicated hardware components for each function.
Solution Approach 2:
The patent combines the power management functionality with the existing control module rather than adding a separate power supply device. The control module integrates both control and power management tasks, merging multiple functions into a unified structure that reduces overall system complexity.
4Use of energy by moving object
If capacitor is used as power supply device, then the chip can be powered during resetting, but the discharge time is short and discharging is unstable
Solution Approach 1:
The patent uses a small-capacity capacitor designed for short-term, temporary power supply during the brief reset operation. Rather than requiring a large, expensive battery for long-term power, the system uses a small capacitor that provides sufficient energy for the short duration of the reset process, accepting its limited capacity as an acceptable trade-off.
5Use of energy by moving object
If storage battery is used as power supply device, then the chip can be powered during resetting, but the peripheral circuit is complex, chip volume is large, cost is high, and battery needs replacement
Solution Approach 1:
The patent employs a small capacitor instead of a storage battery, accepting the capacitor's limited energy capacity in exchange for dramatically reduced complexity, size, and cost. The capacitor's short duration power supply is sufficient for the brief reset operation, making the trade-off advantageous.
Solution Approach 2:
The patent extracts only the essential power supply function needed for the reset operation and implements it through a simple capacitor, removing the need for complex battery management circuits, protection circuits, and replacement mechanisms associated with storage batteries.

AI summary
Disclosed are an automatic reset method for a consumable chip and the consumable chip using the method. The automatic reset method comprises: entering an automatic reset state and shielding a printer command, when it is judged that the ink quantity state is in an ink use-up state; in the automatic reset state, turning off an inner core of the chip and shielding a stop command of the printer; shielding N groups of stop commands of the printer in the automatic reset state and then entering an reset allowing state; and resetting the ink amount data and turning on the inner core of the chip in the reset allowing state. The automatic reset method is fully controlled by a software program, the automatic reset of the chip can be realized without the need of a switch device and a power supply device, inserting and pulling operation does not need to be performed on the consumables, and consumable reset can be achieved only by opening and closing a printer consumable cover.
