Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional power supply system is used, then power supply function is provided, but various fee-charging modes cannot be handled
Solution Approach 1:
The fee-charging apparatus is designed to perform multiple fee-charging modes (charging to user, charging to power supply target, and combination modes) through a single unified system. The apparatus memorizes multiple kinds of power-use-side identification information and power-supply-side identification information, and determines fee-charging targets based on combination sets of these identification information, enabling one apparatus to handle diverse fee-charging scenarios without requiring separate systems for each mode.
2Adaptability or versatility
If identification information memorization is expanded, then fee-charging versatility improves, but information management complexity increases
Solution Approach 1:
The identification information is segmented into two distinct categories: power-use-side identification information (including user identification, power supply target identification, and power use apparatus identification) and power-supply-side identification information (including power supply apparatus identification and power supply source identification). This segmentation allows the system to systematically manage multiple identification types by organizing them into structured groups, where each group serves specific functions in determining fee-charging targets.
Solution Approach 2:
The system transitions from handling single-dimensional identification to multi-dimensional identification by creating combination sets between power-use-side identification information and power-supply-side identification information. This dimensional expansion enables the apparatus to determine fee-charging targets based on paired identification information, effectively managing complexity through structured combination rather than unstructured multiplication of identification types.
3Reliability
If authentication and theft prevention functions are added, then security improves, but device complexity increases
Solution Approach 1:
The authentication function and theft prevention function are merged into the existing fee-charging apparatus rather than being implemented as separate systems. The apparatus uses the same identification information it already memorizes for fee-charging determination to perform authentication by verifying whether the power supply target is authorized to receive power, and to perform theft prevention by detecting stolen power supply targets through the identification information. This merging approach enables security functions without requiring additional dedicated apparatuses.

AI summary
Power supply systems capable of performing various modes of fee-charging are provided. A fee-charging apparatus memorizes two or more kinds of power-use-side identification information of a use side using the power supplied via the power-supply control apparatus, two or more kinds of power-supply-side identification information of a supply side supplying the power via the power-supply control apparatus, and fee-charge-target information predetermined to each of combination sets between the two or more kinds of power-use-side identification information and the two or more kinds of power-supply-side identification information. The fee-charging apparatus receives at least one of the two or more kinds of power-supply-side identification information, at least one of the two or more types of power-use-side identification information and power-use information relating to power supplied from the power supply source to the power supply target, from the power-supply control apparatus via a wired or wireless communication line. The fee-charging apparatus performs a fee-charging process based on the at least one kind of power-supply-side identification information, the at least one kind of power-use-side identification information and the power-use information.
