Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first communication method (one-to-many communication) is used during power feeding, then long-distance communication capability is maintained, but communication delay increases and real-time control is compromised
Solution Approach 1:
The patent dynamically switches between the first communication method (one-to-many, longer range, higher delay) and the second communication method (one-to-one, shorter range, lower delay) based on the power feeding state. When power feeding is active, the system transitions to the second communication method to reduce delay and improve real-time control, while maintaining the capability to switch back to the first method when needed.
Solution Approach 2:
The patent changes communication parameters by switching between different communication methods with distinct characteristics. The first method uses parameters optimized for long-distance one-to-many communication, while the second method uses parameters optimized for low-delay one-to-one communication during power feeding, thereby adapting communication behavior to operational requirements.
2Productivity
If the communication method is switched during power feeding, then communication efficiency is improved, but loss of connectivity may occur
Solution Approach 1:
The patent performs preliminary actions by establishing the second communication method before critical operations during power feeding. The system proactively switches to the low-delay communication method in advance to ensure real-time control capability is available when needed, preventing connectivity issues rather than reacting to them.
Solution Approach 2:
The patent implements feedback mechanisms to monitor the power feeding state and communication quality, using this information to determine when to switch between communication methods. This closed-loop control ensures that switching decisions are based on actual system conditions, improving both efficiency and reliability by avoiding unnecessary switches and maintaining optimal communication throughout the power feeding process.

AI summary
A wireless power feeding apparatus (100) is configured to perform wireless communication with a power reception side apparatus (200) and to perform wireless power transmission to the power reception side apparatus. The wireless power feeding apparatus is provided with: a communicating device (120) configured to switch between a first communication method that allows one-to-many communication and a second communication method that has less communication delay than the first communication method, thereby performing the wireless communication; and a communication controlling device (110) configured to control the communicating device to switch from the first communication method to the second communication method and to perform the wireless communication in the second communication method, on condition that the wireless power feeding apparatus becomes in a state in which the power transmission can be performed, when the communicating device performs the wireless communication in the first communication method.
