Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If binary logic is used for information storage and processing, then device structure is simple and easy to manufacture, but information density is limited and energy dissipation per bit is high
Solution Approach 1:
The patent changes the fundamental parameter of logic states from binary (2 states) to multi-value (at least 3 states) by utilizing ferroelectric nanoparticles that can exhibit multiple stable polarization states. This allows each nanoparticle to store more information bits, thereby increasing information density without proportionally increasing device complexity
Solution Approach 2:
The patent employs ferroelectric nanoparticles as a composite material system between conductive elements, where the ferroelectric material provides multiple stable polarization states. This composite structure enables non-binary logic operations while maintaining a relatively simple capacitor-based device architecture
2Use of energy by moving object
If binary logic devices are miniaturized to reduce energy consumption, then device size decreases, but fundamental limitations are reached due to atomic size constraints and Landauer principle
Solution Approach 1:
The patent changes the energy efficiency approach by transitioning from binary to multi-value logic, where each nanoparticle can represent multiple logic states. This reduces the number of switching operations needed and lowers energy consumption per bit without requiring further miniaturization below atomic scales
Solution Approach 2:
The patent uses individual ferroelectric nanoparticles as discrete information storage units between conductive elements. Each nanoparticle can be independently controlled to exhibit specific polarization states, enabling parallel information storage and processing that reduces overall energy requirements
3Quantity of substance
If pseudo-multi-level logic units are used in solid-state drives, then multi-value logic is achieved, but stochastic loss of information occurs due to analogue writing methods
Solution Approach 1:
The patent transitions from analogue multi-level writing to discrete quantum-based writing by utilizing the quantized polarization states of ferroelectric nanoparticles. Each nanoparticle can be reliably set to specific discrete states (e.g., 0, +1, -1 polarization), eliminating stochastic information loss while maintaining high information density
Solution Approach 2:
The patent replaces the mechanical/analogue writing method with an electric field-based quantum approach. By applying controlled electric fields to induce specific polarization states in ferroelectric nanoparticles, the system achieves reliable digital-like state control instead of analogue continuum writing
