Wireless Power Transmitter Abnormality Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power transmission systems face challenges in managing power supply abnormalities, where a power transmitting apparatus may cause reoccurrence of issues if it continues power supply processing despite abnormalities, which is undesirable.
Innovation Solution
A power transmitting apparatus is configured with a power transmission unit, a reception unit to receive requests and abnormality content from power receiving apparatuses, and a power transmission determination unit to decide whether to stop power transmission to other receiving apparatuses based on the abnormality content, ensuring appropriate processing in case of power transmission abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power transmitting apparatus continues power supply processing after detecting an abnormality, then power transmission to other receiving apparatuses can be maintained, but the abnormality may reoccur causing safety issues
Solution Approach 1:
The power transmitting apparatus receives abnormality content feedback from power receiving apparatuses and uses this information to determine whether to stop power transmission. The reception unit obtains abnormality notifications, and the power transmission determination unit processes this feedback to make informed decisions about continuing or stopping power supply, preventing abnormality reoccurrence while maintaining transmission when safe.
Solution Approach 2:
The system dynamically adjusts power transmission status based on real-time abnormality conditions. The power transmission determination unit evaluates abnormality content and dynamically decides whether to stop power transmission to specific receiving apparatuses or all receiving apparatuses, allowing flexible response to changing conditions rather than fixed stop/go rules.
2Reliability
If the power transmitting apparatus stops power transmission upon receiving an abnormality notification, then safety is improved, but power transmission to other normal receiving apparatuses is interrupted
Solution Approach 1:
The power transmission determination unit applies different actions to different receiving apparatuses based on their specific abnormality status. When an abnormality is detected from one receiving apparatus, the system stops power transmission only to that specific apparatus rather than to all receiving apparatuses, allowing other normal apparatuses to continue receiving power without interruption.
3Productivity
If the power transmitting apparatus performs shift processing to supply power to another receiving apparatus when one stops power, then productivity is maintained, but the risk of abnormality reoccurrence increases
Solution Approach 1:
The system uses abnormality content feedback to determine whether shift processing to another receiving apparatus is safe. The reception unit receives detailed abnormality information, and the power transmission determination unit evaluates this feedback before deciding whether to stop power transmission to the affected apparatus and shift to another apparatus, preventing abnormality reoccurrence while maintaining productivity when safe.
