Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If commercial arbitrary waveform generator or specialized power calibration source is used, then stable signal output is achieved, but random dynamic signal output capability is lost
Solution Approach 1:
The patent implements dynamic signal generation by using a chaos-based pseudo-random sequence generator that continuously updates signal parameters. The system transitions from static waveform generation to dynamic random signal generation by incorporating a feedback loop that continuously generates new pseudo-random sequences to modulate the output signal, enabling the device to adapt its output characteristics in real-time
Solution Approach 2:
The patent changes the fundamental parameters of the waveform generator by introducing chaos theory-based pseudo-random sequencing. The system varies amplitude, frequency, and phase parameters dynamically according to generated pseudo-random sequences, transforming the generator from producing fixed waveforms to producing dynamically varying random signals with controlled statistical properties
2Measurement precision
If OOK control signal is used to truncate instantaneous test current, then dynamic error testing is enabled, but randomness of the stimulated output signal is completely lost
Solution Approach 1:
The patent applies preliminary action by generating pseudo-random sequences in advance using chaos-based algorithms before the actual signal output. These pre-generated sequences with known statistical properties and randomness are then used to modulate the test current, ensuring both measurement precision for dynamic error testing and inherent randomness in the stimulated output
Solution Approach 2:
The patent introduces chaos-based pseudo-random sequences as an intermediary between the control system and the power output. This intermediary layer provides the randomness characteristic while maintaining precise control over the signal properties, allowing dynamic error testing to be performed on signals that exhibit natural random behavior rather than deterministic truncation patterns

AI summary
A random transient power test signal generator based on three-dimensional memristive discrete map, which utilizes a three-dimensional parallel bi-memristor Logistic map module to generate two pseudo-random sequences, and based on the two pseudo-random sequences, uses two waveform output modules to generate a transient voltage signal and a transient current signal respectively, thus the random transient power testing signal is obtained.
