Near-field Communication Data Exchange for Hotel Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for exchanging data between mobile communication units and electronic door locks in environments like hotels require users to perform multiple actions and necessitate the installation of additional data collectors or validation stations, leading to inefficiencies and potential unauthorized access.
Innovation Solution
A method utilizing near-field communication (NFC) between a mobile communication unit, elevator terminals, and electronic door locks allows for seamless data exchange without additional infrastructure, using localization codes and access authorization checks to ensure secure and efficient distribution of access codes and data collection, with data temporarily stored on the mobile device for later transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrared interfaces are installed on all door locks for data exchange, then data collection capability is improved, but device complexity and installation cost increase due to requiring ceiling-mounted data collectors at various locations
Solution Approach 1:
The patent extracts the data collection function from fixed ceiling-mounted infrastructure and relocates it to portable validation stations that can move throughout the environment. This eliminates the need for installing infrared interfaces on all door locks and ceiling-mounted collectors, while maintaining comprehensive data collection capability through the portable station's ability to approach different door locks sequentially.
2Device complexity
If smart cards are used for data exchange with electronic door locks, then device complexity is reduced, but productivity decreases due to requiring regular manual insertion into validation stations for data transfer
Solution Approach 1:
The validation station automatically performs data exchange operations with door locks without requiring manual user intervention. The system autonomously approaches door locks, establishes communication, transfers data, and returns to standby mode, eliminating the need for users to manually insert smart cards and significantly improving data exchange efficiency while maintaining system simplicity.
3Reliability
If manual data transfer operations are required, then security is improved through user control, but ease of operation decreases due to multiple user actions required
Solution Approach 1:
The validation station serves as an intermediary between the user's mobile communication unit and the electronic door locks. It receives authentication requests from the user's device, verifies credentials, and automatically manages data exchange with door locks. This maintains security through automated authentication while eliminating the need for users to perform multiple manual operations, as the validation station handles all data transfer tasks autonomously.

AI summary
The method involves establishing a contact between a mobile communication unit (10) and communication units (20, 21) when the units (10, 20, 21) are at a preset distance (R), and producing a near-field radio communication within the distance. The data is exchanged between the units (10, 20, 21) by the communication, and the data is transmitted from the units (20, 21) to a computer. A contact is established between the unit (10) and another communication unit (30), and the data is exchanged between the units (10, 30) by another radio communication, when the units (10, 30) are at the distance.
