Sliding Door Gesture Control for Adaptive Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face challenges in balancing security and user comfort, particularly in dynamic living conditions such as dense urban environments, where they need to accommodate varying user needs and situations like carrying large objects or using mobility aids.
Innovation Solution
An access control system with a sliding door and a controller that includes a recognition device and sensor unit, allowing users to adjust the opening width based on gestures, ensuring secure and comfortable passage by validating credentials and detecting user height and gestures for adaptive door operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed opening width is stored for each user credential, then security is maintained through credential validation, but user comfort deteriorates when users need to carry large objects or use mobility aids
Solution Approach 1:
The system transitions from a static fixed opening width to a dynamic adaptive opening width that changes based on real-time sensor measurements of user characteristics (height, weight, posture) and detected gestures, allowing the door to adapt to different user needs while maintaining security through credential validation
Solution Approach 2:
The opening width parameter is changed dynamically based on measured user parameters (height, weight, center of gravity position) and detected gestures, allowing the system to optimize the opening width for each user's specific needs rather than using a predetermined fixed value
2Adaptability or versatility
If the sliding door opens to a wide position for all users, then user comfort is improved, but security deteriorates as it cannot accommodate varying user needs or situations
Solution Approach 1:
The system applies different opening width solutions to different users based on their individual characteristics (height, weight, posture) and needs, rather than applying a uniform opening width to all users, thereby optimizing comfort for each user while maintaining appropriate security
3Adaptability or versatility
If a recognition device and sensor unit are added to detect gestures and user characteristics, then user comfort and adaptability are improved, but device complexity increases
Solution Approach 1:
The sensor unit performs multiple functions including detecting user height, weight, center of gravity position, and gestures, thereby reducing the need for separate dedicated devices for each measurement and reducing overall system complexity despite the multiple measurement capabilities
Solution Approach 2:
The system automatically measures user characteristics and detects gestures without requiring manual input from the user, and automatically calculates and adjusts the opening width based on the detected information, eliminating the need for complex user interfaces or manual configuration
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
Enhances security and user comfort by allowing adaptive opening widths based on user needs, improving access control effectiveness and reducing the risk of unauthorized access through gesture recognition and integrated building management system integration.
Implementation Method 1
A sensor unit is arranged on the end face and a processor unit is arranged in an inner space of the sliding door
Implementation Method 2
A recognition device is arranged on the sliding door system or in the vicinity thereof and is communicatively connected to the controller, with the detection device being designed to capture and check credentials presented by a user
Implementation Method 3
The controller is also designed to recognize a gesture made by the user and to trigger a movement of the sliding door depending on said gesture

AI summary
The invention relates to a system for controlling access to a restricted area in a building, which system has a sliding door system and a controller for the sliding door system. The sliding door system has a door frame and a sliding door which can be displaced by a drive unit actuated by the controller. The door frame has a passage region and a wall shell region which accommodates the sliding door in the open position. The sliding door has an end face which points toward the passage region in the open position. The controller has a processor unit and a sensor unit, the sensor unit is arranged on the end face and the processor unit is arranged between the door leaves. A recognition device captures and checks credentials presented by a user. If the credentials are valid, a record is determined in a storage device, in which the credentials are assigned to an opening width (W) of the sliding door, in order to trigger the movement of the sliding door according to said opening width (W). The controller is designed to recognize a gesture made by the user and to actuate the sliding door depending on said gesture in deviation from the opening width (W).
