Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a consuming device is placed within the general area and range of a WPT transmitter, then power transfer is adequate, but power transfer efficiency is not optimal
Solution Approach 1:
The system continuously monitors power transfer efficiency metrics and uses this feedback to dynamically adjust the transmitter or receiver position via the moving mechanism, ensuring optimal alignment is maintained throughout the charging process
Solution Approach 2:
The patent introduces a moving mechanism that enables dynamic repositioning of either the transmitter or receiver along predetermined patterns, transforming the static alignment problem into a dynamic optimization process that adapts to changing conditions
2Area of stationary object
If the consuming device is larger in size (e.g., car, truck, train), then power transfer area is increased, but alignment optimization becomes more difficult
Solution Approach 1:
The system divides the large receiving surface into multiple discrete positions or zones along predetermined patterns, allowing the moving mechanism to systematically evaluate and optimize alignment at each segment rather than treating the entire large surface as a single complex problem
Solution Approach 2:
The patent extends the alignment optimization from two-dimensional surface placement to three-dimensional spatial adjustment by incorporating vertical positioning and angular orientation through the moving mechanism, adding dimensional freedom to the alignment process
3Loss of energy
If the charger or device is manually positioned for optimal alignment, then power transfer efficiency is improved, but time and labor are consumed
Solution Approach 1:
The system performs self-alignment by automatically monitoring power transfer efficiency and using the moving mechanism to reposition itself or the receiving device without human intervention, making the alignment optimization process autonomous
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated moving mechanism controlled by electronic sensors and control systems that monitor power transfer metrics and execute positioning adjustments based on real-time data
