Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If wireless power distribution is extended over longer ranges, then power delivery capability is improved, but security control difficulty increases

Engineering Contradiction:

Improvepower distribution rangeVSAvoidunauthorized device detection

Core Design Contradiction:

Length of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The system continuously monitors power coupling characteristics and communicates with target devices to verify authorization status. The master server receives usage assessments and detects anomalies in power transfer, enabling real-time feedback control to prevent unauthorized charging even at extended ranges.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

A master server acts as an intermediary between power source distribution centers and target devices. It establishes key-pair identifiers, monitors power couplings, and coordinates authentication, enabling secure extended-range power distribution without direct peer-to-peer trust verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of stationary object

If multiple power source distribution centers are deployed, then power distribution coverage is improved, but usage assessment complexity increases

Engineering Contradiction:

AI summary

Disclosed aspects relate to wireless power distribution management in an open environment. A key-pair identifier is established in a master server. The key-pair identifier can indicate both a first wireless power target device and a first wireless power source distribution center. The master server detects an indication of a wireless power coupling between the first wireless power target device and a second wireless power source distribution center. A usage assessment is determined for the wireless power coupling by the master server using the key-pair identifier. The usage assessment can relate to the first wireless power source distribution center. The master server may provide or output the usage assessment for the wireless power coupling.
