Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication methods between imaging devices and chips are inadequate for transmitting implicit data such as anti-counterfeit information and usage state parameters, leading to inefficiencies and prolonged communication times, which hinder rapid start and response of imaging devices.
Innovation Solution
A communication method where the chip alternately transmits implicit data and master data on the same data line during clock pulse signals, allowing the imaging device to read either or both types of data without disrupting normal communication, using a control unit and memory to manage and update implicit data independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the chip transmits only master data through the traditional communication procedure, then the communication process is simple and fast, but the implicit data such as anti-counterfeit information and usage state parameters cannot be transmitted
Solution Approach 1:
The patent segments the data transmission process into two distinct modes: a first communication procedure for transmitting master data using traditional protocols, and a second communication procedure for transmitting implicit data using time-division multiplexing on the same data line. This segmentation allows both types of data to be transmitted efficiently without interfering with each other, resolving the contradiction between information completeness and communication efficiency
Solution Approach 2:
The patent implements periodic action by using time-division multiplexing where the data line alternates between transmitting master data and implicit data during different time slots within clock pulse periods. This periodic switching enables the system to maintain high communication efficiency for master data while periodically transmitting implicit data, thus resolving the contradiction between information loss prevention and productivity
2Loss of information
If an additional READ/WRITE operation is added to transmit implicit data, then the implicit data can be transmitted, but the communication time is prolonged and imaging efficiency is reduced
Solution Approach 1:
The patent merges the transmission of master data and implicit data into a single communication framework by utilizing the same data line through time-division multiplexing. Instead of requiring separate READ/WRITE operations for different data types, the system combines both data transmissions into one unified communication process, eliminating the need for additional operation overhead and reducing total communication time
Solution Approach 2:
By implementing periodic time-division multiplexing where implicit data is transmitted during specific time slots within the existing clock pulse cycle, the patent avoids adding extra communication operations. The periodic transmission of implicit data occurs within the already-established communication rhythm, preventing communication time prolongation while ensuring information completeness
3Loss of information
If the chip stores both master data and implicit data, then comprehensive information is available, but the device complexity increases
Solution Approach 1:
The patent applies universality by making the existing data line serve multiple functions: it transmits both master data and implicit data through time-division multiplexing. The same physical communication interface and protocol framework are used for both data types, eliminating the need for separate hardware structures and keeping the chip design simple while achieving comprehensive data transmission
Solution Approach 2:
The patent resolves the complexity issue by adding a time dimension to the data transmission process rather than adding physical hardware dimensions. By utilizing the time domain for multiplexing different data types on the same data line, the system achieves comprehensive information storage and transmission without increasing spatial or structural complexity of the chip

AI summary
Disclosed is a chip, an imaging cartridge, and a communication method between the chip and the imaging device. The chip is stored with implicit data and master data. The communication method comprises the following steps. The chip receives a clock pulse signal and a READ instruction from the imaging device, wherein within one clock pulse signal period, the chip transmits at least one bit of implicit data and one bit of master data to the data line within different time slots, respectively, and the imaging device reads data from the data line while the chip is transmitting the master data. And the chip receives a WRITE instruction from the imaging device, writes the master data received from the imaging device into a memory, and updates the implicit data stored in the memory. The implicit data and the master data can be transmitted in one and a same data line. The imaging device can read the master data only, or can read the implicit data also, by means of an information reading device having a function of reading implicit data, while the chip is transmitting the implicit data, thereby ensuring both data transmission efficiency and data security of the implicit data.
