Adaptive Locking System Open-Delay Control From Movement Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems do not adequately accommodate individuals with disabilities or impairments, requiring them to repeatedly unlock or contact administrators to adjust the open delay time, which is often insufficient for their access needs.
Innovation Solution
A system that adjusts the open delay time of locking systems based on individual movement parameters, such as speed and gait, using sensors and user devices to dynamically extend the lock open time for comfortable access without additional hardware, allowing for secure and efficient access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the open delay time is set to a fixed default value (3 seconds for general users, 15 seconds for persons with disabilities), then the locking system operates simply and reliably, but it cannot accommodate individual variations in movement speed and requires repeated unlocking or administrative intervention for persons with disabilities
Solution Approach 1:
The patent applies dynamics by transitioning from a static, fixed open delay time configuration to a dynamic system that automatically adjusts the open delay time based on real-time detection of user movement parameters. Sensors detect walking speed and gait characteristics, and the system dynamically extends the open delay time for users with slower movement patterns without requiring manual reconfiguration or administrative intervention.
Solution Approach 2:
The system implements self-service by automatically detecting user characteristics through sensors and autonomously adjusting the open delay time without requiring administrative intervention or user re-encoding. The locking system serves itself by using sensor data to determine appropriate delay times based on detected movement parameters, eliminating the need for users to contact administrators or re-unlock the door.
2Ease of operation
If the open delay time is extended for persons with disabilities, then access comfort is improved, but it requires updating lock configurations and re-encoding keycards which is time-consuming and complex
Solution Approach 1:
The system applies preliminary action by pre-configuring the locking system with sensor capabilities that continuously monitor user movement parameters. Instead of waiting for administrative intervention or manual configuration changes, the system is prepared in advance to detect and respond to user needs in real-time, automatically extending the open delay time before the user even needs to request it.
Solution Approach 2:
The patent implements feedback by using sensors to continuously monitor user movement parameters such as walking speed and gait characteristics. This feedback loop allows the system to detect when a user is moving slowly and automatically adjust the open delay time accordingly, creating a responsive system that adapts to user needs without manual intervention.
3Adaptability or versatility
If the open delay time is increased to allow slower movement, then accessibility for disabled persons is improved, but security may be compromised due to extended unlocked periods
Solution Approach 1:
The system applies local quality by providing different open delay time extensions to different users based on their individual movement characteristics. Rather than applying a uniform extension to all users or none at all, the system locally adapts the delay time to match each user's specific needs, extending it only as much as necessary for their safe passage while maintaining tighter security for faster-moving users.
Solution Approach 2:
The patent implements parameter changes by dynamically modifying the open delay time parameter based on detected movement parameters such as walking speed and gait characteristics. The system changes this temporal parameter in real-time based on sensor data, allowing extended delays for slow-moving users while maintaining shorter delays for faster users, thus balancing accessibility and security.

AI summary
Systems and methods for control of a locking system (106) are disclosed. In some embodiments, a system comprises one or more sensors (108) configured to generate output signals indicating one or more movement information of a subject. The system comprises at least one processor operatively connected with the one or more sensors, and memory storing instructions executable by the at least one processor, the instructions when executed cause the system to determine, using the output signals from the one or more sensors, one or more movement parameters of the subject; and send, based on the determined movement parameters of the subject, an instruction to the locking system to adjust an open delay time for the locking system, the open delay time being time the locking system remains open.
