Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If binary logic is used in computing circuits, then device structure is simple and ease of manufacture is high, but information density is low and energy efficiency deteriorates
Solution Approach 1:
The patent changes the fundamental parameter of logic states from binary (2 states) to multi-value (at least 3 states). By using ferroelectric nanoparticles that can be set to multiple discrete polarization states through application of specific voltages or charges, the device achieves higher information density without requiring proportional increases in physical device count
Solution Approach 2:
The patent segments the ferroelectric material into discrete nanoparticles arranged between conductive elements. Each nanoparticle can be individually addressed and set to specific polarization states, enabling multi-value logic operations while maintaining a relatively simple overall device structure with just a pair of conductive elements
2Loss of energy
If binary logic is used in computing circuits, then device structure is simple, but energy loss increases due to fundamental limitations
Solution Approach 1:
The patent transitions from binary to multi-value logic states, where at least three discrete polarization states are achievable. This parameter change allows more information to be stored per device, reducing the total number of devices needed and thereby reducing overall energy loss in the computing system
Solution Approach 2:
The ferroelectric nanoparticles possess remanent polarization states that are maintained without continuous energy input. The nanoparticles can be set to specific states through voltage application and then retain those states autonomously, reducing energy loss compared to systems requiring continuous power for state maintenance
3Quantity of substance
If multi-value logic device is implemented, then information density increases and energy loss reduces, but device complexity increases
Solution Approach 1:
The patent divides the ferroelectric material into discrete nanoparticles that can be individually controlled. This segmentation allows each nanoparticle to represent a logic state, and with at least three achievable states per nanoparticle, high information density is achieved while the overall device structure remains simple with only a pair of conductive elements
Solution Approach 2:
The patent creates a universal multi-value logic device where the same physical structure (ferroelectric nanoparticles between two conductive elements) can achieve at least three discrete polarization states. This multi-functional capability allows the device to handle complex logic operations without requiring multiple specialized device structures
