Solution Overview
Problem
Existing contactless power transmission systems fail to determine appropriate coil IDs between multiple power receiving devices and power transmission devices, leading to inefficient power transmission.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of power receiving devices exist simultaneously without coil ID determination, then the system can support multiple devices, but appropriate contactless power transmission cannot be realized
Solution Approach 1:
The patent implements a negotiation process that occurs before actual power transmission begins. During this preliminary phase, the power transmission device receives coil IDs from power receiving devices, determines which device to prioritize, and establishes transmission parameters. This preliminary action ensures that when multiple devices are present, the system reliably selects one device for power transmission while supporting the presence of multiple devices.
2Speed
If power transmission starts without negotiation and setup processes, then the system responds faster, but appropriate and efficient power transmission cannot be realized
Solution Approach 1:
The patent structures the power transmission process with negotiation and setup phases occurring before the actual power transmission. The negotiation process establishes communication parameters and device identification, while the setup process configures transmission parameters based on the determined device. This preliminary configuration enables efficient power transmission by avoiding parameter mismatches and retransmissions, thus maintaining productivity despite the additional initial steps.
