Innovation Solution
A security system utilizing NFC sensors and controllers in mobile devices and access control devices to generate and verify temporary security codes, allowing secure personnel access while tracking device IDs and managing access permissions based on unique IDs and event notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional access control systems are used, then security is maintained, but convenience and speed of access are reduced
Solution Approach 1:
The patent replaces traditional mechanical access control systems (physical keys, cards, or biometric scanners requiring direct contact) with NFC-based wireless communication. The mobile device communicates with the access control system through near-field communication, eliminating the need for physical interaction while maintaining security. This substitution improves ease of operation by allowing contactless access while preserving reliability through encrypted communication protocols and unique device identification verification.
2Ease of operation
If permanent access codes are used, then ease of access is improved, but security control and tracking capability are worsened
Solution Approach 1:
The patent implements dynamic access codes that are generated temporarily for each access attempt rather than using static permanent codes. The system generates a unique access code based on the mobile device's identification and validates it against the access control system. This dynamic approach maintains ease of access for authorized users while enabling comprehensive tracking and logging of each access event, as each code is uniquely tied to a specific device and time of access.
3Productivity
If NFC technology is implemented for access control, then convenience and speed are improved, but system complexity increases
Solution Approach 1:
The patent leverages the universal nature of NFC technology, which is already integrated into modern mobile devices for various functions such as contactless payments and data exchange. By utilizing this existing infrastructure, the access control system can achieve fast and convenient access without requiring completely new hardware. The system complexity is managed by using standard NFC communication protocols and integrating with existing mobile device capabilities, rather than implementing a proprietary complex communication system.
4Reliability
If temporary security codes are generated for each access, then security is improved, but time consumption for code generation and verification increases
Solution Approach 1:
The patent performs preliminary actions by pre-registering mobile devices with the access control system and storing their unique identification information in advance. When a user attempts access, the system quickly retrieves the stored identification and generates the temporary security code through a streamlined process. This preliminary setup eliminates the need for time-consuming code generation and verification during actual access attempts, as the validation process simply checks whether the presented code matches the pre-registered device identification, thereby maintaining both high security and fast access speed.

AI summary
A security system may include a plurality of electronic devices, each having a unique identification (ID) associated therewith and configured to generate a temporary security code based upon the unique ID. The system may further include at least one mobile wireless communications device including a first Near-Field Communication (NFC) circuit, and a mobile controller configured to receive the temporary security code from a given electronic device from among the plurality of electronic devices. The system may also include an access control device associated with a personnel access position and including a second NFC sensor and a security controller. The security controller may be configured to receive the temporary security code from the first NFC sensor via NFC communications, selectively grant personnel access based upon the received temporary security code, and determine the unique ID associated with the given electronic device.
