Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual observation is used for positioning the receiver, then the operation is simple, but the positioning accuracy is low
Solution Approach 1:
The patent replaces manual visual observation with an automated detection coil system that uses electromagnetic induction to detect the receiver's position. The detection coils transmit detection signals and receive feedback signals automatically, eliminating the need for human observation and significantly improving positioning accuracy.
Solution Approach 2:
The detection coil system performs self-positioning detection by automatically transmitting detection signals, receiving feedback signals from the receiver, and determining the receiver's position region without requiring external intervention. The system serves itself by using the receiver's own feedback signal for positioning.
2Productivity
If the receiver is not aligned with the transmitter, then the device structure remains simple, but the charging efficiency is low and energy loss is high
Solution Approach 1:
The patent implements a feedback mechanism where the receiver sends feedback signals to the transmitter based on the detection signals received. The processor analyzes these feedback signals to determine the receiver's position region, enabling automatic alignment adjustment to optimize charging efficiency and reduce energy loss.
Solution Approach 2:
The detection coils perform preliminary position detection before the actual charging process begins. By determining the receiver's position region in advance, the system can pre-adjust the alignment to ensure optimal charging conditions, preventing energy loss before it occurs.
3Measurement precision
If multiple detection coils are used to improve positioning accuracy, then the measurement precision increases, but the device complexity increases
Solution Approach 1:
The patent divides the detection area into multiple segments by using multiple detection coils with different detection regions. Each coil is responsible for detecting specific areas, and the processor integrates information from all coils to determine the overall position region, achieving high precision through systematic segmentation.
Solution Approach 2:
The detection coil system is designed to perform multiple functions: transmitting detection signals, receiving feedback signals, determining position regions, and providing alignment guidance. This multi-functional design reduces the need for separate systems for each function, thereby managing complexity while enhancing precision.
