Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security solutions for delivery vehicles, such as traditional locks and padlocks, are inconvenient and insecure, leading to increasing thefts and attacks on drivers due to the rising value of goods being delivered.
Innovation Solution
A method utilizing RFID tags to indicate intent and a user device to request access to electronic locks, where the tag identifier and lock identifier are separate, allowing for accurate intent indication without reducing lock flexibility, and employing decentralized access delegation to manage access rights without a central control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locks or padlocks are used for delivery vehicles, then device complexity is reduced, but security and driver convenience deteriorate
Solution Approach 1:
The patent replaces traditional mechanical locks and padlocks with an electronic lock system that uses RFID tags for authentication. The electronic lock controller communicates with user devices via wireless communication, eliminating the need for physical keys and mechanical locking mechanisms, thereby improving security while maintaining simplicity through electronic automation.
Solution Approach 2:
The patent introduces RFID tags as intermediary elements between the user and the electronic lock. The tags store identification information that the electronic lock controller reads to authenticate users, serving as a mediator that simplifies the interaction while enhancing security through contactless authentication.
2Ease of operation
If traditional locks are used, then device complexity is low, but ease of operation deteriorates due to inconvenience for drivers
Solution Approach 1:
The electronic lock system enables self-service operation where drivers can independently authenticate and unlock vehicles using RFID tags without requiring assistance from dispatchers or security personnel. The system automatically verifies credentials and grants access, improving ease of operation while the automated processes manage the underlying complexity.
Solution Approach 2:
The replacement of manual key-based mechanical locking with electronic authentication using RFID tags and wireless communication provides contactless, automated locking and unlocking operations, significantly improving driver convenience while the electronic system handles the complexity of authentication protocols.
3Reliability
If a central access control system is used, then access management is centralized, but reliability deteriorates due to single point of failure
Solution Approach 1:
The patent segments the access control functionality by distributing authentication capabilities to individual electronic lock controllers and user devices. Each lock controller can independently verify RFID tags and grant access without requiring continuous communication with a central server, eliminating the single point of failure while maintaining decentralized authentication through segmented system architecture.

AI summary
According to a first aspect, it is presented a method for requesting access to a physical space controlled by an electronic lock. The method is performed in a user device and comprises the steps of: reading a tag using a near field radio protocol, yielding a tag identifier, the tag being distinct from the electronic lock; finding, based on the tag identifier, a lock identifier associated with the tag identifier, wherein the tag identifier is distinct from the lock identifier; and sending an access request message to the electronic lock having the lock identifier.
