Existing access control systems on cruise ships are limited in functionality and require passengers to carry physical credentials, lacking advanced features for personalized stateroom experiences and efficient crew access, while also not providing comprehensive security and data analytics.
Innovation Solution
A multifunctional smart door device equipped with facial recognition technology, proximity sensors, and a processor that unlocks staterooms based on authorized profiles, allows crew access, and provides personalized settings, live streaming, and anonymized foot traffic analysis, integrated with a networked computing system for enhanced security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition technology and multiple sensors are integrated into the door device, then passenger comfort and security are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functional components (facial recognition camera, proximity sensors, electronic door lock, data storage, and processing units) into a single integrated smart door device. This merging approach enables the system to perform multiple functions (access control, security monitoring, passenger identification) while maintaining a unified device structure, thereby improving security without proportionally increasing complexity.
Solution Approach 2:
The smart door device is designed to perform multiple functions: facial recognition for passenger identification, proximity detection for safety, electronic locking for access control, and data storage for passenger profiles. This multi-functionality allows a single device to replace multiple separate systems, improving security and convenience while managing complexity through functional integration.
2Productivity
If local data store with customer profiles is implemented, then access control efficiency is improved, but data storage requirements increase
Solution Approach 1:
The system implements a local data store within the door device that stores only the necessary customer profile data (facial recognition data and access permissions) locally, while more comprehensive passenger information is stored on the ship-wide network. This local quality approach enables fast access control decisions at the door level without requiring extensive data storage capacity in the door device itself.
Solution Approach 2:
The data storage is segmented into local and remote components. The local data store in the door device holds only essential access control data for immediate processing, while the ship-based network stores comprehensive passenger profiles. This segmentation reduces the data storage burden on individual door devices while maintaining efficient access control through local processing of critical data.
3Reliability
If wide angle camera and proximity sensor are added, then security monitoring capability is improved, but device complexity increases
Solution Approach 1:
The wide angle camera and proximity sensor are integrated into the same housing as the facial recognition system, creating a unified security monitoring apparatus. This merging allows the system to perform multiple security functions (area monitoring, proximity detection, facial recognition) from a single device location, improving security monitoring capability while avoiding the complexity of multiple separate devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The smart door device enhances passenger comfort and security by eliminating the need for physical credentials, streamlining access for crew, and providing anonymized data for improved safety and operational efficiency.
Implementation Method 1
a proximity sensor disposed at the exterior of the housing and configured to detect the presence of an object within the public area of the cruise ship adjacent to the door of the stateroom
Implementation Method 2
capture, by the wide angle camera in response to the signal, an image of a face of a person disposed within the public area
Implementation Method 3
locally generate, based on one or more facial recognition software algorithms and the at least a portion of the one or more profiles, a facial recognition result indicating that the person is one of the customers permitted to access the stateroom

AI summary
Multifunction smart door devices may be part of a system of multifunction smart door devices installed within or near stateroom doors of a cruise ship. Each smart door device can control access to a stateroom based on facial recognition or a wireless credential and can perform other functions such as controlling stateroom personalization features, providing an electronic peephole function, allowing controlled access for authorized crew members, accommodating remote unlocking, and providing notifications. Data obtained by the smart door devices can be provided to the cruise operator for service, safety, or security purposes, such as for anonymized foot traffic analysis, hazard detection, and stateroom access auditing. Smart door device functionality may be implemented in part by customers' mobile devices.
