Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single antenna is used for both noncontact communication and noncontact charging, then device complexity is reduced, but the efficiency of noncontact charging and data transmission decreases
Solution Approach 1:
The patent implements a variable Q-value antenna that can dynamically adjust its Q value between a first value (for communication) and a second value (for charging). The control unit switches the antenna's Q value based on the detected function requirement, allowing a single antenna to adaptively optimize performance for either noncontact communication or noncontact charging, thereby resolving the contradiction between device simplicity and functional efficiency.
2Device complexity
If a single antenna is used for both noncontact communication and noncontact charging, then device complexity is reduced, but communication efficiency decreases
Solution Approach 1:
The variable Q-value antenna system allows the antenna to switch between a first Q value optimized for communication and a second Q value optimized for charging. When communication is detected as the required function, the antenna adjusts to the first Q value, ensuring communication efficiency is maintained despite using a shared antenna resource.
3Productivity
If Q value of the antenna is increased for noncontact charging, then charging efficiency is improved, but communication performance deteriorates
Solution Approach 1:
The system dynamically adjusts the antenna's Q value based on the active function. When noncontact charging is required, the antenna switches to a second Q value (higher than the first) to optimize charging efficiency. When noncontact communication is required, the antenna switches to a first Q value to maintain communication performance, thus resolving the trade-off between charging efficiency and communication reliability.
4Reliability
If Q value of the antenna is decreased for noncontact communication, then communication performance is improved, but charging efficiency deteriorates
Solution Approach 1:
The variable Q-value antenna enables the system to optimize for communication by setting the Q value to a first value when communication is the active function. When charging becomes the active function, the Q value switches to a second value to optimize charging efficiency. This dynamic adjustment resolves the contradiction between communication performance and charging efficiency.
