Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data processing components (ALU) are separate from system memory and local registers, then processing capability is improved, but operational complexity and power consumption increase
Solution Approach 1:
The patent combines data processing and storage functions into a unified nanomagnetic device. Multiple nanomagnetic triangles are magnetically coupled to form logic gates (AND, OR, NOT, XOR) that perform computation intrinsically within the storage medium, eliminating the need for separate ALU and memory components connected via data buses.
Solution Approach 2:
The nanomagnetic triangles serve multiple functions simultaneously: they store data in their magnetic states and perform logical operations through magnetic coupling. The same physical structures that hold information also execute processing, making the system universally functional without requiring dedicated processing components.
2Productivity
If data is transferred between system memory and ALU via data buses, then processing is enabled, but data corruption risks and power consumption increase
Solution Approach 1:
By merging storage and processing into the same nanomagnetic structures, the patent eliminates data transfer through external buses. Data remains localized within the magnetically coupled triangle system throughout processing, removing the vulnerability of data corruption during transport between separate components.
3Stability of the object's composition
If constant power supply is used to maintain processor states in DRAM, then data persistence is achieved, but power consumption increases
Solution Approach 1:
The nanomagnetic triangles maintain their magnetic states and associated logic operations without requiring external power for refreshing. The magnetic domains are inherently stable and retain information passively, making the system self-sufficient for data persistence without continuous energy input.
Solution Approach 2:
The patent replaces the electrical refresh mechanism of DRAM with stable magnetic domain states. Instead of using electrical signals to continuously maintain data in capacitive memory, the system uses the inherent stability of magnetically ordered domains to preserve information without active power consumption.
4Ease of operation
If binary data (0 or 1 per bit) is used for processing, then simplicity is achieved, but information density decreases
Solution Approach 1:
The patent changes the fundamental parameter of data representation from binary (2 states per unit) to quaternary (4 states per triangle). Each nanomagnetic triangle can exist in four distinct magnetic states, allowing two bits of information to be encoded in a single physical structure, thereby doubling the information density compared to traditional binary systems.

AI summary
Techniques of processing and/or persistently store data using nanomagnetic elements are disclosed herein. In one example, a processing circuit includes a substrate and a plurality of nanomagnetic elements spaced apart from one another. The plurality of nanomagnetic elements have shape-induced magnetic anisotropy and individually include a geometric center and at least three vertices extending away from the geometric center. One of the nanomagnetic elements has a vertex magnetically coupled to another vertex of another nanomagnetic element such that a magnetic polarity change at the vertex at the one of the plurality of nanomagnetic elements causes a responsive magnetic polarity change at the vertex at the another nanomagnetic element to generate an output of the processing circuit.
