Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power feeding is used to transmit power to multiple terminals, then convenience and safety are improved, but power transmission efficiency and charging speed deteriorate
Solution Approach 1:
The patent segments the power transmission process by dividing multiple terminals into different groups based on their power reception capabilities and requirements. The base station transmits power signals tailored to each group's specific needs, enabling efficient simultaneous charging of multiple terminals with different battery levels and power requirements.
Solution Approach 2:
The patent implements dynamic power transmission by continuously monitoring the power reception status of multiple terminals and adjusting transmission parameters in real-time. The base station dynamically modifies power signal characteristics based on feedback from terminals, optimizing charging efficiency while maintaining the ability to serve multiple devices simultaneously.
2Ease of operation
If wireless power feeding is used to transmit power to multiple terminals, then convenience and safety are improved, but transmissible power increases
Solution Approach 1:
The patent applies local quality by transmitting power signals with different characteristics to different terminals based on their specific requirements. Each terminal receives power optimized for its individual battery state and power needs, rather than using a uniform transmission approach for all terminals.
Solution Approach 2:
The patent changes transmission parameters such as power signal frequency, amplitude, and modulation characteristics based on the specific requirements of each terminal. By adjusting these parameters dynamically, the system can efficiently transmit power to multiple terminals with different power reception capabilities without requiring excessive total transmission power.
3Productivity
If optimal transmission timing is determined based on reception history, then power transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by having terminals send power reception status information to the base station before actual power transmission begins. The base station uses this advance information to pre-calculate optimal transmission timing and configure power signals accordingly, improving efficiency without requiring complex real-time decision-making during transmission.
Solution Approach 2:
The patent employs feedback mechanisms where terminals report their power reception status, battery levels, and other relevant information to the base station. The base station uses this feedback to determine optimal transmission timing and adjust power signal characteristics, creating a closed-loop control system that improves efficiency through information-based decision-making rather than complex hardware.
