Regeneration Chip Switch Circuit Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of printing consumables, regeneration chips experience signal interference and collision due to direct contact with native chips, leading to printer malfunction during communication.
Innovation Solution
A regeneration chip with a switch circuit that controls connection or disconnection between printer and native chip contacts, ensuring the printer receives signals only from the regeneration chip and not from the native chip, thereby preventing interference and collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the regeneration chip uses a single-layer direct contact with the native chip, then the structure is simple and easy to manufacture, but signal interference and collision occur when both chips send signals simultaneously
Solution Approach 1:
The patent applies the dynamics principle by introducing a switch circuit that dynamically changes the connection state between the regeneration chip and native chip contacts. The switch circuit can connect or disconnect based on communication needs, transforming a static single-layer direct contact structure into a dynamic multi-state structure. This resolves the contradiction by maintaining structural simplicity while enabling dynamic signal routing to prevent interference and collision.
2Duration of action of moving object
If the printer connection contact is always connected to both regeneration chip and native chip contacts, then signal transmission is continuous, but the printer receives interfering signals from both chips simultaneously
Solution Approach 1:
The patent applies segmentation by dividing the single contact layer into multiple independent contact layers. The first contact layer connects the printer to the regeneration chip, while the second contact layer connects the native chip to the regeneration chip. This segmentation allows independent control of signal paths, enabling the printer to receive signals only from the regeneration chip without interference from the native chip, while maintaining continuous signal transmission capability.
3Reliability
If a switch circuit is introduced to control connection/disconnection between contacts, then signal interference is avoided, but the device complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a switch circuit as a mediator between the printer connection contact and the native chip connection contact. The switch circuit acts as a controlled intermediary that selectively connects or disconnects the native chip from the printer based on communication needs. This intermediary element prevents direct interference while maintaining the ability to transmit signals continuously, resolving the contradiction between reliability improvement and complexity increase.

AI summary
Embodiments of this application relate to the technical field of consumable chips, and provide a regeneration chip and a contact control method therefor. In this way, connection or disconnection between a printer connection contact and a native chip connection contact of the regeneration chip may be controlled, thereby avoiding problems of signal interference and collision that are caused because the regeneration chip and a native chip send signals to a printer at the same time. The regeneration chip comprises a printer connection contact, a native chip connection contact, and a switch signal end, where the native chip connection contact is connected to the printer connection contact via a switch circuit, the switch circuit is further connected to the switch signal end, and the switch circuit is configured to connect or disconnect the native chip connection contact to or from the printer connection contact under control of the switch signal end.
