TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If capacitor charging and discharging is used to implement neuron firing, then the neuron device can transmit signals, but the response speed is reduced due to charging and discharging delays
Why choose this principle:
The patent extracts and removes the capacitor component from the neuron device structure. By eliminating the capacitor, the charging and discharging delays that cause firing delays are completely removed, allowing the neuron to respond immediately to input signals without the time loss associated with capacitor charge/discharge cycles.
Principle concept:
If capacitor charging and discharging is used to implement neuron firing, then the neuron device can transmit signals, but the response speed is reduced due to charging and discharging delays
Why choose this principle:
The patent replaces the capacitor-based electrical storage mechanism with a spontaneous polarization switching mechanism in a dielectric material. This substitution eliminates the need for charging and discharging processes, enabling instantaneous neuron firing response to input signals and dramatically improving response speed.

Abstract
A neuron device is described. The neuron device is based on spontaneous polarization switching which includes a plurality of gate electrodes, a plurality of drain electrodes, a plurality of source lines, a dielectric layer, and a semiconductor layer. The gate electrodes are arranged parallel to each other. The drain electrodes are arranged parallel to each other. The source lines are arranged between the gate electrodes and the drain electrodes and parallel to each other. The dielectric layer is formed at intersections between the gate electrodes and the source lines. The semiconductor layer is formed at intersections between the drain electrodes and the source electrodes. The drain electrodes function as synapse-after-neuron linking terminals. The gate electrodes adjust an arrangement direction of electrical dipoles of the dielectric layer to control a firing time point and a firing height of the neuron device.
