Wireless Power Supply for Mobile Device Transaction Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often run out of battery power during transactions, preventing successful authentication and completion of financial or other sensitive operations with transaction terminals.
Innovation Solution
Transaction terminals equipped with a wireless power supply and antenna provide radio wave radiation to power mobile devices, enabling authentication and transaction completion even when the mobile device's battery is depleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power transfer is implemented to power mobile devices during transactions, then transaction reliability is improved, but device complexity increases
Solution Approach 1:
The system divides the transaction terminal into separate functional modules: a wireless power transfer module (with power supply and antenna) and an authentication module (with NFC reader). This segmentation allows each module to operate independently, improving reliability while managing complexity through modular design.
Solution Approach 2:
The transaction terminal is designed to perform multiple functions: wireless power transfer, NFC authentication, and transaction processing. By integrating these functions into a single universal device, the system improves transaction reliability without requiring multiple separate devices, thus managing overall system complexity.
2Productivity
If wireless power transfer is used to authenticate mobile devices, then transaction speed is improved, but energy consumption increases
Solution Approach 1:
The wireless power transfer operates in periodic pulses rather than continuous transmission. The power is transferred in short bursts sufficient to enable authentication, then stopped. This periodic operation accelerates transaction processing while minimizing overall energy consumption compared to continuous power transfer.
Solution Approach 2:
The system provides just enough wireless power to enable authentication and transaction completion, rather than fully charging the device. This partial action approach improves transaction speed by providing necessary power quickly, while avoiding excessive energy consumption that would result from complete charging.
