Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-configured static voltage configuration values are used in wireless charging, then device complexity is reduced and ease of manufacture is improved, but charging efficiency deteriorates and power waste increases due to inability to adapt to dynamic charging conditions
Solution Approach 1:
The patent implements dynamic voltage configuration by allowing the PRU to adjust voltage settings in real-time based on charging conditions. The voltage configuration value is no longer fixed but changes dynamically according to measured charging power, temperature, and other parameters, resolving the contradiction between static configuration simplicity and dynamic charging efficiency requirements
Solution Approach 2:
The patent changes the voltage configuration parameter from a static pre-set value to a dynamic value that is adjusted based on real-time charging conditions. The PRU measures charging power and other parameters, then modifies the voltage configuration value accordingly, enabling adaptation to different charging scenarios while maintaining manageable system complexity
2Device complexity
If pre-configured static voltage configuration values are used, then device complexity is reduced, but energy waste increases due to non-optimal voltage settings in various charging situations
Solution Approach 1:
The patent implements a feedback mechanism where the PRU continuously measures charging power, temperature, and other parameters, then uses this feedback information to adjust the voltage configuration value. This closed-loop control ensures optimal voltage settings are maintained while minimizing energy waste, without significantly increasing device complexity
Solution Approach 2:
The PRU autonomously adjusts its own voltage configuration based on measured charging conditions without requiring external intervention. The system performs self-optimization by comparing measured parameters against target values and automatically modifying voltage settings, reducing both complexity and energy waste
3Productivity
If dynamic voltage configuration is implemented based on real-time measurements, then charging efficiency is improved and power waste is reduced, but device complexity and measurement requirements increase
Solution Approach 1:
The PRU autonomously performs measurements of charging power and other parameters, then automatically adjusts its own voltage configuration without requiring complex external control systems. This self-service approach improves charging efficiency while minimizing the increase in overall device complexity by keeping the control logic within the PRU itself
4Ease of operation
If static voltage configuration values are used, then ease of operation is improved, but adaptability to different charging situations deteriorates
Solution Approach 1:
The patent transforms the static voltage configuration into a dynamic system that automatically adapts to different charging situations. The PRU measures charging conditions and adjusts voltage settings in real-time, providing both ease of operation (automatic adjustment) and adaptability (response to varying conditions) simultaneously

Implementation Method 1
A power transmission method through the electromagnetic induction corresponds to a scheme of transmitting power between a first coil and a second coil. When a magnet is moved in a coil, induction current is generated. By using the induction current, a magnetic field is generated at a transmission side, and electric current is induced according to a change of the magnetic field so as to make energy at a reception side.
Implementation Method 2
Prof. Soljacic of MIT announced 'Coupled Mode Theory' in 2005, in which electricity is wirelessly transferred using a power transmission principle of the resonance scheme even if a device to be charged is separated from a charging device by several meters. The research team made an electromagnetic wave containing electrical energy resonate instead of making sound resonate.
