Barrier Operator Timer Control for Reliable Remote Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barrier operator systems face issues with users neglecting to close barriers after remotely opening them due to network outages or forgetfulness, leading to security vulnerabilities.
Innovation Solution
Implementing a barrier operator system with a motor and control module that initiates a window of time upon receiving a remote request, automatically closing the barrier after the timer expires, ensuring local control over the closure process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If barrier operators are remotely controlled via network, then user convenience is improved, but reliability of barrier closure deteriorates due to network outages and user forgetfulness
Solution Approach 1:
The system initiates a time window upon receiving a remote open command, during which the barrier must be closed. This preliminary action sets up the conditions for automatic closure if the barrier is not manually closed within the specified time frame, ensuring closure reliability without compromising remote control convenience
Solution Approach 2:
The system provides feedback to the remote server about the barrier's operational status and the time window state. This feedback mechanism allows the system to monitor whether the barrier was manually closed or needs automatic closure, maintaining reliability while preserving ease of remote operation
2Reliability
If automatic closure is implemented, then barrier closure reliability is improved, but device complexity increases due to additional timer and control logic
Solution Approach 1:
The barrier control system performs multiple functions: it processes manual close commands, responds to remote open commands, manages time windows, and executes automatic closure. By making the control system universal, the patent avoids adding separate dedicated automatic closure devices, thus improving reliability without proportionally increasing complexity
Solution Approach 2:
The barrier operator system manages its own closure timing and execution autonomously after receiving a remote open command. The local controller initiates the time window and executes automatic closure without requiring continuous external control, reducing the complexity burden on the overall system while ensuring reliable closure
3Reliability
If time window mechanism is added, then network-dependent failures are mitigated, but loss of time occurs due to waiting period
Solution Approach 1:
The time window is initiated immediately upon receiving the remote open command, before any potential network issues occur. This preliminary establishment of the time window ensures that the system is prepared for network failures and can execute automatic closure based on local timing, mitigating network dependency while managing the time loss through efficient timing

AI summary
A barrier operator system includes a remote server and a barrier operator configured to move a barrier. The remote server is configured to transmit a first communication to the barrier operator, receive a window acknowledgement from the barrier operator that indicates the barrier operator has initiated a window of time, and in response to receipt of the window acknowledgement transmit a barrier open request to the barrier operator. The barrier operator is configured to receive the first communication from the remote server, initiate the window of time in response to receipt of the first communication and transmit the window acknowledgement, receive the barrier open request, and in response to receipt of the barrier open request during the window of time, initiate a timer and close the barrier in response to expiration of the timer.
