Solution Overview
Problem
Current printing devices face issues with short circuits between high voltage and detecting terminals on ink cartridges due to ink dripping or pin deformation, causing damage to the cartridge and device, and existing solutions either require additional hardware or detect damage after installation, posing safety hazards.
Innovation Solution
A consumable chip with separated high voltage and detecting terminals connected by a conductive structure that diverts high voltage to a low voltage terminal, preventing it from reaching the detecting terminal and triggering a short-circuit detection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If high voltage terminals and detecting terminals are placed adjacent to each other on the ink cartridge chip, then the chip structure is compact and simple, but ink dripping or pin deformation causes short circuits between these terminals leading to damage of the chip and printing device
Solution Approach 1:
A conductive structure is introduced as an intermediary element between the high voltage terminal and detecting terminal. This conductive structure serves as a mediator that diverts electrical current away from the detecting terminal when short circuit conditions occur, preventing direct contact between high voltage and detecting terminals while maintaining the compact chip layout
Solution Approach 2:
The invention converts the potentially harmful short circuit condition into a beneficial detection mechanism. When ink dripping or pin deformation causes abnormal electrical contact, the conductive structure redirects the current flow to trigger a short circuit detection mechanism, transforming a damaging event into a safe, detectable signal that alerts the system to the abnormality
2Reliability
If a short circuit detecting circuit is added to the printing device, then short circuits can be detected, but the damage to memory elements on the ink cartridge chip has already occurred and the device complexity increases
Solution Approach 1:
The conductive structure and associated detection mechanism are pre-installed on the ink cartridge chip itself before mounting to the printing device. This preliminary arrangement ensures that short circuit detection capability is built into the consumable component, allowing immediate detection and prevention of damage before the cartridge is installed in the expensive printing device
Solution Approach 2:
The ink cartridge chip performs its own short circuit detection function through the integrated conductive structure and detection mechanism. The chip autonomously monitors its own electrical integrity and triggers detection signals without requiring external detection circuits in the printing device, making the system self-diagnostic
3Reliability
If a detecting terminal and hardware circuit are added to the ink cartridge chip substrate, then short circuit detection can be performed independently on the chip, but the cost and complexity of the chip increase significantly
Solution Approach 1:
The conductive structure serves multiple functions simultaneously: it acts as an electrical connector, a current diversion path for short circuit protection, and a trigger mechanism for detection. This multi-functionality eliminates the need for separate dedicated detection hardware circuits, reducing overall chip complexity while maintaining independent detection capability
