Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power transmission systems lack the ability to efficiently provide power during emergencies, such as disasters, where traditional power sources may be unavailable, and fail to prioritize power distribution to critical devices effectively.
Innovation Solution
A power transmission system comprising a power receiver and a power transceiver that can transmit and receive wireless power, with a controller to manage emergency power requests, allowing the power transceiver to function as a transmitter during emergencies to supply power to the power receiver, even when the primary power source is unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a power transmitter uses authentication to transmit power only to registered power receivers during normal circumstances, then security and controlled power distribution are improved, but the system cannot provide power during emergencies when traditional power sources are unavailable
Solution Approach 1:
The power transmitter dynamically changes its authentication behavior based on the operational state. During normal circumstances, it enforces authentication for registered devices only. During emergencies, it switches to a mode that allows power transmission to unregistered devices as well, enabling adaptability to emergency conditions while maintaining security during normal operation
Solution Approach 2:
The system changes the authentication parameter from 'registered devices only' during normal operation to 'registered and unregistered devices' during emergencies. This parameter change allows the system to maintain security under normal conditions while becoming adaptable to emergency situations where rapid power distribution is critical
2Productivity
If a power transmitter transmits power to all power receivers during emergencies without authentication, then power distribution speed and emergency response are improved, but security control and targeted power distribution are worsened
Solution Approach 1:
The power transmitter dynamically adjusts its authentication requirements based on the emergency state. In emergency mode, it reduces authentication barriers to enable rapid power distribution to all receivers, while in normal mode, it maintains controlled access. This dynamic adjustment resolves the contradiction between speed and control by adapting the level of control to the operational context
3Duration of action of stationary object
If a power receiver transmits an emergency power transmission request during an emergency, then power supply continuity is improved, but the system complexity for handling emergency requests increases
Solution Approach 1:
The power receiver autonomously detects emergency conditions and transmits emergency power requests without requiring complex external coordination. The power transmitter autonomously responds to these requests by switching to emergency transmission mode. This self-service mechanism maintains power supply continuity while avoiding the need for complex centralized emergency management systems
