Method supporting access control actions in a system for delivery and/or pick-up of parcels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access control devices, such as those used for parcel boxes, often require physical or electronic keys for both deliverers and users, which can be inconvenient and prone to misuse, and existing systems do not efficiently manage authorization for actions initiated by separate control units, limiting their usability and applicability.
Innovation Solution
A method and system that allow an access control device to check authorization for actions initiated by a separate control unit, using encrypted data and digital signatures, enabling secure communication between devices and control units to manage access to secured areas, such as parcel boxes, through a network of devices and servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical or electronic keys are used for access control, then security is maintained, but convenience deteriorates and misuse risk increases
Solution Approach 1:
The patent replaces physical key mechanisms with electronic access control devices that use digital authentication. The mechanical key-lock system is substituted with electronic components including processors, memory units, and communication interfaces that enable keyless access through digital credentials, thereby improving convenience while maintaining security.
Solution Approach 2:
The patent uses digital copies of access credentials stored in electronic form rather than physical keys. The access authority is replicated as digital data that can be verified by the access control device, eliminating the need for physical key distribution and reducing misuse risk while maintaining security controls.
2Adaptability or versatility
If access control devices manage multiple control units, then versatility improves, but device complexity increases
Solution Approach 1:
The access control device is designed with universal functionality to interact with multiple types of control units including parcel boxes, door locks, and garage door openers. The device incorporates generic communication protocols and standardized interfaces that enable it to manage diverse control units through a unified approach, enhancing versatility without proportionally increasing complexity.
Solution Approach 2:
The access control device serves as an intermediary between the user and multiple control units. It abstracts the complexity of communicating with different control units by providing a standardized interface layer, thereby enabling versatile control management while keeping the device's internal complexity manageable through modular architecture.
3Reliability
If authorization checking is performed for actions by separate control units, then security improves, but processing time increases
Solution Approach 1:
The access control device performs preliminary authorization verification by checking digital credentials and permissions before initiating actions on controlled units. This pre-authorization process ensures security requirements are met before execution, preventing unauthorized actions while maintaining efficient processing through advance validation.
Solution Approach 2:
The patent replaces time-consuming manual authorization verification with automated electronic checking processes. Digital signatures, encrypted credentials, and processor-based validation algorithms substitute for manual security checks, thereby maintaining high security standards while significantly reducing processing time through automated verification.

AI summary
A server 120 receives a message that an authorization for requesting an action is issued via a first device 110 , with the action being able to be initiated by a separate control unit 131 . The server compiles information that identifies the action and that allows the first device 110 to verify authorization. The compiled information is transmitted to a second device 150 . The first device 110 may receive a message from the second device 150 requesting the initiation of the action. The first device 110 checks the authorization of the request based on the message received and whether the action is an action that is to be initiated by the first device 110 or by the control unit 131 . If it is determined that there is authorization and that the action is to be initiated by the control unit 131, the first device 110 transmits a request to the control unit 131 to initiate the action.
