Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data signal modulation is performed using conventional amplitude modulation circuit in high-power induction-type power supply system, then data transmission function is achieved, but high voltage current causes energy dissipation and MOSFET component burnout
Solution Approach 1:
The patent changes the voltage parameter from high voltage to low voltage (5V or lower) for the square wave signal used in data modulation. This parameter change reduces energy dissipation during modulation while maintaining data transmission capability through the receiving-end coil to supplying-end coil feedback path.
Solution Approach 2:
The patent introduces a dedicated feedback path through the receiving-end coil to supplying-end coil as an intermediary channel for data transmission. This separate path allows data modulation without interfering with the main power transmission path, reducing energy loss and preventing component burnout.
2Adaptability or versatility
If data signal modulation is performed using conventional amplitude modulation circuit, then data transmission is enabled, but power supply instability occurs due to MOSFET burnout
Solution Approach 1:
The patent segments the power supply system into separate functional paths: a main power transmission path and a dedicated data feedback path through the coils. This segmentation isolates the data modulation function from the power transmission function, preventing modulation-related failures from affecting power supply stability.
Solution Approach 2:
The coil feedback path serves as an intermediary channel that carries both power and data signals separately. By using this intermediary path for data transmission, the system achieves data capability while maintaining power supply reliability through electrical isolation of the modulation function.
3Speed
If high voltage current is used for data signal modulation, then data transmission range is extended, but MOSFET component lifespan is reduced due to burnout risk
Solution Approach 1:
The patent changes the voltage parameter to low voltage (5V or lower) for modulation signals, which extends component lifespan by eliminating burnout risk. Data transmission effectiveness is maintained through optimized modulation techniques and the dedicated feedback path, proving that high voltage is not necessary for effective communication.
Solution Approach 2:
The patent treats the MOSFET components as long-lasting elements by using low-voltage modulation that prevents burnout. This approach prioritizes component longevity over high-power modulation capability, aligning with the goal of extending system operational duration.
