Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry or scanning of charging point identifier is required, then authentication accuracy is improved, but user operation complexity increases
Solution Approach 1:
The patent replaces the mechanical interaction of manually entering or scanning the charging point identifier with a wireless electromagnetic field-based identification system. The near-field communication module transmits the charging point identifier automatically when the user approaches, eliminating the need for manual input devices (keyboards, cameras) while maintaining authentication accuracy through secure wireless communication.
Solution Approach 2:
The charging station performs self-identification by automatically transmitting its charging point identifier via near-field communication when a user approaches. This eliminates the need for the user to actively scan or input the identifier, as the system serves itself by providing the identification information passively, thereby reducing operational complexity while maintaining authentication reliability.
2Ease of operation
If near-field transmission module is added, then user operation simplicity is improved, but device complexity increases
Solution Approach 1:
The near-field communication module serves multiple functions: it transmits the charging point identifier for authentication, provides device identification, and enables wireless communication between the charging station and user's mobile device. By integrating this single module to perform multiple tasks, the patent reduces overall system complexity compared to having separate components for each function.
Solution Approach 2:
The patent combines the charging point identifier storage and transmission functions into the existing near-field communication module, which is already part of the authentication system. This merging of functions into a single integrated component minimizes the increase in device complexity while achieving the goal of simplified user operation.
3Reliability
If charging point identifier must be manually captured, then system security is improved, but time consumption increases
Solution Approach 1:
The charging point identifier is pre-loaded into the near-field communication module during system setup or manufacturing. This preliminary action eliminates the need for real-time manual capture or scanning during the charging initiation process, reducing time consumption while maintaining security through pre-authenticated identifier transmission that occurs automatically when the user approaches.
Solution Approach 2:
The patent replaces the time-consuming mechanical processes of manual entry or optical scanning with instantaneous wireless electromagnetic transmission. The near-field communication module transmits the pre-stored charging point identifier automatically, reducing the time required for identifier capture from several seconds (manual entry/scanning) to a fraction of a second, while maintaining system security through encrypted wireless communication.
