Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power transmission systems lack the ability to dynamically adjust power levels based on ambient conditions and perform authentication autonomously, especially when foreign substances are detected or the charging environment changes.
Innovation Solution
Implementing a method and apparatus for wireless power transmission that includes negotiating power indicators, transmitting and receiving packets to adjust power levels dynamically, and performing authentication through bit pattern responses, allowing the system to adapt to changing environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wireless power transmission apparatus waits for the wireless power reception apparatus to initiate communication, then the reception apparatus can start the communication process, but the transmission apparatus cannot properly adjust the available power index dynamically according to surrounding environment
Solution Approach 1:
The transmission apparatus performs preliminary actions by proactively initiating communication and authentication with the reception apparatus before power transfer begins. This allows the transmission apparatus to negotiate and establish the available power index dynamically according to surrounding environmental conditions, rather than waiting for the reception apparatus to start communication.
2Adaptability or versatility
If the available power index is fixed, then the system structure is simple, but the transmission apparatus cannot adjust power according to surrounding environment/situation
Solution Approach 1:
The available power index is transformed from a fixed parameter to a dynamic one that can be adjusted in real-time. The transmission apparatus negotiates the available power index with the reception apparatus during the communication phase, allowing the system to adapt to changing environmental conditions and power availability while maintaining a relatively simple overall structure through standardized negotiation protocols.
3Adaptability or versatility
If the transmission apparatus proactively initiates communication, then it can dynamically adjust the available power index, but it requires leading communication and authentication capability
Solution Approach 1:
The transmission apparatus performs preliminary communication and authentication actions before power transfer. This proactive approach enables the transmission apparatus to establish the available power index dynamically, and the automation is achieved through standardized communication protocols that handle the negotiation process automatically without requiring complex manual intervention.
