Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors are used to detect signals, then energy exchange occurs between the sensor and the signal, but this limits the detection of extremely weak signals and may modify or destroy the signal
Solution Approach 1:
The patent introduces a vector potential field as an intermediary that couples the electron beam to the signal without direct energy exchange. The AB sensor detects signals through the vector potential A, which acts as a mediator between the electron beam and the external signal source, allowing phase modulation without energy transfer between the sensor and the signal
Solution Approach 2:
The patent replaces conventional electromagnetic sensing mechanisms with a quantum mechanical phase interference mechanism. Instead of using traditional electromagnetic interactions that require energy exchange, the system uses the quantum phase of electrons modulated by the vector potential to detect signals, substituting mechanical/electromagnetic coupling with quantum phase coupling
2Measurement precision
If conventional electromagnetic sensing methods are used, then signals can be detected, but the detection threshold is limited and signals six orders of magnitude weaker cannot be detected
Solution Approach 1:
The patent changes the fundamental detection parameter from electromagnetic field strength to quantum phase. By measuring phase shifts in the electron beam caused by the vector potential rather than direct electromagnetic field interactions, the system achieves detection thresholds six orders of magnitude lower than conventional methods
Solution Approach 2:
The patent segments the electron beam into multiple paths that recombine to create an interference pattern. This segmentation allows the phase information to be extracted through interference, enabling detection of extremely weak signals that would be imperceptible in a single-beam configuration
3Reliability
If energy exchange is used for signal detection, then the signal can be detected, but the signal may be modified or destroyed in the process
Solution Approach 1:
The vector potential serves as a non-intrusive intermediary that transfers information about the signal to the electron beam without energy exchange. This mediator approach preserves signal integrity while enabling detection, as the vector potential couples the signal to the electron phase without modifying the signal itself
Solution Approach 2:
The patent substitutes direct electromagnetic interaction with quantum phase modulation. By using the vector potential to modulate the electron wavefunction phase rather than exchanging energy with the signal, the system maintains signal integrity while achieving detection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for the detection of extremely weak signals, potentially six orders of magnitude weaker than conventional methods, with enhanced sensitivity and no energy exchange, providing a high signal-to-noise ratio and enabling miniaturization for various applications.
Implementation Method 1
According to the AB effect, the angular phase of a particle inside a vector potential of a signal can change even if the actual fields embodying the signal are zero. This effect may occur without the exchange of any physical quantity
