Remote Access Control for Barrier Operators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing access to secured premises, such as overhead doors, face challenges when the owner is absent or busy, as they require physical transmission of wireless transmitters or codes, which is inconvenient and insecure, and also complicate troubleshooting due to increasing features and complexity.
Innovation Solution
A method and mobile device application that allows owners to remotely send access rights to guests or service technicians over a communication network, enabling secure and time-restricted access to movable barriers and diagnostic data, using mobile device software and computer-readable media to manage access and operational data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmitters are used to grant access to guests, then access convenience is improved, but security control deteriorates because the owner cannot easily revoke access or prevent reentry
Solution Approach 1:
The access control system transitions from static code-based access to dynamic session-based access. The mobile application implements time-restricted access windows and allows the owner to dynamically grant or revoke access rights remotely, making the security system adaptive rather than fixed.
Solution Approach 2:
The system incorporates notification features that provide feedback to the owner when a guest attempts to access the premises outside authorized time periods or when access is granted. This allows the owner to monitor and control access in real-time, enhancing security while maintaining convenience.
2Reliability
If stationary keypads with codes are used for access control, then security control is improved, but ease of operation deteriorates because the owner must manually change codes for each guest and cannot easily revoke access
Solution Approach 1:
Instead of using physical keys or static codes, the system uses digital copies of access credentials stored on mobile devices. Each guest receives a digital access credential through the application that can be remotely invalidated by the owner, eliminating the need to physically change codes or retrieve physical keys.
Solution Approach 2:
The mobile application serves multiple functions: it acts as the access credential, the authorization mechanism, the revocation system, and the notification platform. This multi-functional approach replaces multiple separate systems (keypads, code management, access revocation procedures) with a single integrated solution.
3Adaptability or versatility
If barrier operators include increasing numbers of features and options, then functionality and utility are improved, but diagnostic complexity and troubleshooting difficulty worsen
Solution Approach 1:
The mobile application serves as an intermediary between the service technician and the complex barrier operator system. It provides a simplified interface that can remotely access, diagnose, and control the barrier operator, translating complex system states into user-friendly information and control options.
Solution Approach 2:
The system enables self-diagnostic capabilities where the barrier operator can automatically report its status, operational data, and error conditions to the mobile application. This allows technicians to remotely assess problems without needing to physically inspect the complex hardware, and enables basic troubleshooting to be performed automatically.
Data Source
AI summary
A computing device using diagnostic application software described herein allows an owner or operator of a premises to provide a service technician access to operational data from a movable barrier operator so that the technician's computing device can troubleshoot for possible issues with the operation of the barrier operator. The owner's computing device can send credentials to the technician mobile device so that the technician's computing device can then utilize the application to access the operational data. For added security, the application can further give the owner computing device control over the type and duration of access provided to the technician.
