Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electromagnetic induction is used for wireless charging, then power transmission is achieved, but the distance between charging device and power receiving device must be kept within a small range
Solution Approach 1:
The patent changes the fundamental parameter of wireless power transmission from electromagnetic induction to radio frequency transmission. This parameter change enables power transmission over much longer distances while maintaining effective power delivery to the receiving device.
Solution Approach 2:
The patent substitutes the electromagnetic induction mechanism with a radio frequency transmission mechanism. This replacement allows the system to overcome the distance limitations inherent in electromagnetic induction while maintaining the wireless power transmission function.
2Device complexity
If wireless charging device has poor flexibility, then device structure is simplified, but the flexibility of wireless power receiving device deteriorates
Solution Approach 1:
The patent segments the wireless charging system into distinct functional modules: a wireless charging module in the charging device and a power receiving module in the receiving device. This segmentation allows each module to be independently optimized and configured, improving the flexibility and adaptability of the power receiving device without complicating the overall system architecture.
Solution Approach 2:
The patent implements a universal communication interface between the charging device and power receiving device, allowing the system to support multiple functions and configurations. The communication module enables coordinated operation between devices, enhancing the versatility of the power receiving device while maintaining a relatively simple charging device structure.
