Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wireless power transmission is performed through free space in habited environments, then power delivery capability is improved, but exposure levels of transmitted signals increase and efficiency decreases due to low energy transfer rate
Solution Approach 1:
The patent introduces authentication platforms and authorization mechanisms as intermediaries between the wireless power transmission system and receiving devices. The system queries authentication platforms to verify device identities and receives authorization decisions, enabling controlled power delivery that improves efficiency by preventing unauthorized energy consumption while maintaining delivery capability to authenticated devices
Solution Approach 2:
The system dynamically changes operational parameters by adjusting power delivery based on authentication status and authorization levels. Authenticated devices receive optimized power delivery parameters while unauthenticated devices are denied or limited, thereby improving overall transmission efficiency by directing energy only to authorized receivers
2Reliability
If device authentication and authorization mechanisms are implemented, then security and power delivery optimization are improved, but system complexity increases
Solution Approach 1:
The authentication platform serves multiple functions: it authenticates device identities, authorizes power delivery, and provides verification services for the wireless power transmission system. This multi-functional approach consolidates security operations into a single system, managing complexity while enhancing reliable and secure power delivery
Solution Approach 2:
The system implements feedback loops where the wireless power transmission system queries the authentication platform, receives authorization decisions, and adjusts power delivery accordingly. This feedback mechanism ensures secure power delivery by continuously verifying device authentication status while maintaining manageable system complexity through automated decision-making

AI summary
Techniques are described for authenticating device in wireless power delivery environments. In some embodiments, a request for energy delivery is received from devices. The request may include an identifier, e.g., a client identification (ID). The charger may query a remotely located authentication platform via a network with the client ID. The authentication platform compares the client ID against devices that have been registered within the system. If the device is properly provisioned, the authentication platform may return an acceptance of authentication to the charger. In addition to device authentication, the current disclosure covers the ability to control the environment within a wireless network, and perform system diagnostics by monitoring the network environment.
