Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different memristor materials are used in parallel, then the adaptability and versatility of the system is improved, but the device complexity increases
Solution Approach 1:
The system divides the memristor network into multiple parallel branches, each containing different memristor materials (e.g., first memristor material, second memristor material). This segmentation allows each material to contribute different electrical characteristics, enabling customized signal responses while maintaining a relatively simple overall parallel structure that avoids more complex series or feedback configurations.
2Manufacturing precision
If physical or chemical modifications are applied to control oxygen vacancy transmission rate, then the manufacturing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent employs physical modifications (such as annealing treatments, oxygen plasma exposure, or ion implantation) and chemical modifications (such as atomic layer deposition of oxide layers or chemical vapor deposition) to precisely control the oxygen vacancy transmission rate in memristor materials. These parameter changes enable fine-tuning of electrical characteristics like resistance switching ratios and switching voltages, achieving manufacturing precision despite the complexity of the modification processes.
