Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a short-circuit detection circuit is provided on the recording device, then short circuit detection can be performed, but the detection occurs after the ink cartridge installation detection is completed, causing damage to the storage unit before detection
Solution Approach 1:
The patent implements preliminary short-circuit detection by integrating a detection terminal and detection unit into the ink cartridge chip itself. The detection occurs during the installation detection phase, before the ink cartridge is fully mounted and before any damage can occur to the storage unit. This preliminary action ensures that short circuits are identified at the earliest possible moment, preventing subsequent damage.
2Reliability
If a battery is provided in the chip for short-circuit detection, then the detection can be performed, but the manufacturing cost increases and the detection cannot be performed when the battery runs out
Solution Approach 1:
The patent makes the connecting terminals serve multiple functions: they provide electrical connection for normal operation and simultaneously serve as power supply terminals for the short-circuit detection unit. This eliminates the need for separate battery power, reducing device complexity while maintaining detection capability throughout the product lifecycle.
Solution Approach 2:
The detection unit is designed to draw power from the connecting terminals during normal operation, using the existing power supply infrastructure of the system. This self-service approach eliminates the need for dedicated power sources like batteries, simplifying the chip structure while ensuring continuous detection capability.
3Reliability
If a short-circuit detection circuit is provided on the recording device, then short circuit detection can be performed, but additional hardware is required in the recording device
Solution Approach 1:
The patent extracts the short-circuit detection functionality from the recording device and relocates it to the ink cartridge chip. This includes the detection terminal, detection unit, and associated power supply connections, all of which are integrated into the ink cartridge assembly. This extraction simplifies the recording device structure while maintaining detection capability.
