Chip Controller Time Control Parameter Signal Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses, multiple consumable chips powered on simultaneously can experience signal conflicts due to varying initialization times and frequencies, making it difficult for the apparatus to identify which chip is sending a low-level signal, thus affecting detection accuracy.
Innovation Solution
The implementation of a chip with an installation detecting terminal and a chip controller that outputs a low level after powering on, with a storage unit to store a time control parameter, ensuring that each chip outputs its low level at a unique time point, preventing signal conflicts and allowing for accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple chips are controlled to output low levels for detection simultaneously, then detection coverage is improved, but signal conflict occurs making it difficult to identify which chip is sending the signal
Solution Approach 1:
The patent implements periodic action by assigning different time intervals for each chip to output low-level detection signals. The controller sequentially activates each chip's detection terminal at predetermined different time points, transforming simultaneous signal output into time-separated periodic signals. This allows the main body to identify which specific consumable is being detected while maintaining comprehensive detection coverage across all consumables.
2Productivity
If multiple chips output low levels at the same time, then detection efficiency is improved, but signal conflict prevents accurate identification of the detecting chip
Solution Approach 1:
The patent applies segmentation by dividing the simultaneous detection process into separate time segments for each chip. Instead of all chips outputting signals at once, each chip is assigned a specific time slot or time interval to output its low-level detection signal. This temporal segmentation maintains detection efficiency by systematically covering all chips while ensuring reliable identification of which chip is active at any given moment.
Solution Approach 2:
The patent implements dynamics by making the detection signal output timing flexible and adjustable for each chip. The controller dynamically assigns different time intervals or time points for each chip to output signals, rather than using a fixed simultaneous timing scheme. This dynamic timing approach allows the system to adaptively manage signal output across multiple chips, preventing conflicts while maintaining efficient detection operations.

AI summary
A chip, a chip set, an electrical parameter detection method, a consumable, and an image forming apparatus are provided in embodiments of the present disclosure. The chip is capable of being installed on the consumable; and the consumable is capable of being detachably installed on the image forming apparatus. The chip includes an installation detecting terminal; a chip controller configured to control the installation detecting terminal to output a low level after the chip is powered on; and a storage unit configured to store a time control parameter, where the time control parameter is configured to control a time point for the installation detecting terminal to output the low level. The above configuration can realize that the signal conflict between a plurality of chips is not generated when detecting whether the plurality of chips is in a desired contact with the image forming apparatus.
