Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional QR codes and tactile displays are used for locker access, then the system provides basic identification and opening functionality, but the user interaction becomes complex and difficult to operate
Solution Approach 1:
The patent replaces traditional mechanical QR code scanning and tactile display interfaces with a conversational AI system that uses natural language processing. Users interact with the locker system through chat messages, replacing the need for physical QR code readers and complex display interactions, thereby simplifying user operation while maintaining system functionality
Solution Approach 2:
The patent introduces a conversational AI intermediary between the user and the locker system. This intermediary handles all interactions through natural language conversations, acting as a mediator that translates user intentions into system actions and displays appropriate responses, thereby simplifying the user interface while maintaining complex system capabilities
2Adaptability or versatility
If more sensors and functionalities are added to smart lockers, then the system capabilities are enhanced, but the ease of use for users deteriorates
Solution Approach 1:
The patent implements a universal conversational interface that handles multiple functions through a single interaction mode. The same chat-based interface is used for locker identification, payment, authentication, and control, making the system versatile while maintaining consistent and simple user interaction across all functionalities
Solution Approach 2:
The conversational AI system provides self-service functionality by automatically handling user interactions, authentication, and locker control without requiring user intervention in complex procedures. The system autonomously manages the locking process, payment verification, and access control through automated conversational responses
3Extent of automation
If automated locker management is implemented, then the control process is simplified, but the need for secure authentication and data synchronization increases system complexity
Solution Approach 1:
The patent implements continuous feedback mechanisms where the conversational AI system constantly synchronizes with the locker control unit and database. The system receives real-time status updates through conversation, validates authentication data, and provides feedback on locker state, enabling automated management while maintaining secure data synchronization through ongoing conversational exchanges

AI summary
Smart locker system comprising a locker cabinet with multiple lockers and a control unit configured to decrypt and validate Key Response codes; a cloud-based locker engine module with a chat management unit using Natural Language Processing, a database, comprising data of the lockers and users, a backend module and a back-office module for admins; and a communications module, connecting the control unit of the locker cabinet to the cloud-based locker engine. The system is controlled by a smart locker conversational access procedure comprising: starting a conversation on a chat/conversation platform as a response of a user request by using Natural Language Processing; identifying the user by its telephone number; querying database for checking availability; generating and validating payment links as a function of minutes of service, generating a Key Response code for opening a locker; decrypting the KR provided by the user to the locker cabinet; and opening a locker.
