Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional wireless power transmission systems are used, then devices can receive power wirelessly, but the systems are inefficient and expensive
Solution Approach 1:
The system segments the wireless power transmission into two distinct modes: magnetic induction for short-range high-efficiency power transfer, and radio frequency for long-range communication and control. This segmentation allows each mode to operate in its optimal efficiency range, resolving the contradiction between wireless power delivery and energy loss.
Solution Approach 2:
The patent introduces a dual-antenna receiver design where one antenna is optimized for magnetic induction and another for radio frequency. This intermediary structure enables the system to switch between transmission modes based on distance and power requirements, maintaining high efficiency while enabling wireless operation.
2Duration of action of stationary object
If devices are made stationary with hardwired power, then continuous power is supplied, but the devices lose mobility
Solution Approach 1:
The system transitions from static hardwired power delivery to dynamic wireless power transmission. The dual-mode wireless system adapts its transmission method based on real-time conditions, enabling devices to move freely while maintaining continuous power supply through automatic mode switching between magnetic induction and radio frequency.
3Ease of operation
If wireless power receivers include communication ability, then user control and monitoring are enabled, but device complexity increases
Solution Approach 1:
The patent merges power reception and communication functions into a single integrated receiver unit with dual antennas. This combination eliminates the need for separate communication hardware, reducing overall device complexity while enabling both wireless power transfer and bidirectional communication for user control and monitoring.
4Power
If traditional wireless power systems are used, then power can be transmitted, but communication and control signals cannot be effectively transmitted
Solution Approach 1:
The system segments communication and power functions by using magnetic induction exclusively for power transfer and radio frequency for communication and control signals. This segmentation prevents signal interference and ensures both power transmission and data communication occur without loss or degradation.
