Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate coils are used for energy and data transmission with distinct frequency ranges, then interference between energy and data transmission is reduced, but device complexity increases
Solution Approach 1:
The system divides the transmission function into separate coils: one coil dedicated to energy transmission and another coil dedicated to data transmission. This segmentation eliminates mutual interference between energy and data channels, ensuring reliable data transmission while maintaining wireless energy transfer capability.
Solution Approach 2:
The patent employs distinct frequency ranges for energy and data transmission. The energy transmission uses a higher frequency range while data transmission uses a lower frequency range, creating frequency separation that prevents interference. This parameter differentiation allows both functions to coexist without mutual disruption.
2Reliability
If contact-based connector systems are used, then secure transmission of energy and data signals is achieved, but wear and vibration problems occur leading to transmission errors
Solution Approach 1:
The patent replaces mechanical contact-based connector systems with wireless electromagnetic induction-based transmission systems. This substitution eliminates mechanical wear and vibration issues inherent in contact-based systems while maintaining secure transmission of energy and data signals through electromagnetic fields.
3Ease of operation
If electrical inductive or capacitive systems are used for wireless transmission, then contactless energy or data transmission is achieved, but mutual interference occurs leading to errors and energy losses
Solution Approach 1:
The system separates energy transmission and data transmission into distinct coils, preventing mutual interference between the two wireless transmission channels. This segmentation maintains the advantages of contactless transmission while eliminating the interference problems that occur when both signals share the same transmission path.
Solution Approach 2:
By assigning different frequency ranges to energy and data transmission coils, the system creates parameter differentiation that prevents electromagnetic interference. This allows both wireless transmission functions to operate simultaneously without compromising transmission accuracy or causing energy losses.
