Movable Barrier Operator Transmitter Identification Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable barrier systems with imminent motion notification often cause user frustration due to delays in operation when the user is present locally, as they expect immediate action upon command, especially when operated remotely without visual contact.
Innovation Solution
The movable barrier operator differentiates between local and remote commands by using transmitter identification codes, signal formats, and communication methods to determine whether to activate the imminent motion notification, allowing it to operate with or without the notification based on the type of command received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If eminent motion notification is activated for all remote operations, then safety of remote users is improved, but user frustration increases due to unnecessary delays when operating locally
Solution Approach 1:
The system applies different notification behaviors to different operational contexts: when the transmitter is locally present (within visual contact), no notification delay is applied; when remotely located, the full eminent motion notification is activated. This contextual differentiation resolves the contradiction by tailoring the safety notification to the user's actual location and needs.
Solution Approach 2:
The notification system dynamically adjusts its behavior based on the transmitter's location status. The operator controller transitions between two operational modes: local operation mode (no delay, no notification) and remote operation mode (delay with notification). This dynamic adaptation allows the system to maintain safety for remote users while avoiding frustration for local users.
2Adaptability or versatility
If transmitter location detection is implemented, then appropriate notification activation is improved, but device complexity increases
Solution Approach 1:
The system uses an intermediary indicator (such as an LED light or visual signal) to communicate the transmitter's location status to the operator controller. This simple intermediary mechanism enables the controller to determine whether the user is locally present or remotely located without requiring complex tracking or monitoring hardware, thus achieving adaptability with minimal added complexity.
Solution Approach 2:
The transmitter itself provides location information through its own indicator system. The operator controller simply reads this self-provided information to determine the appropriate notification behavior. This self-service approach eliminates the need for separate detection systems, maintaining low device complexity while achieving the desired adaptability.

AI summary
A movable barrier system with a moving-barrier imminent motion notification includes a movable barrier and a movable barrier operator connected to control movement of the movable barrier between a first position and a second position. To reduce user dissatisfaction with the moving-barrier imminent motion notification, communications to the movable barrier operator include information to assist the operator in determining whether to operate the moving-barrier imminent motion notification in combination with moving the door or to specifically command that the moving-barrier imminent motion notification operate or not. The communication may include a signal or input separate from and in addition to a typical command signal or input to the operator. By other approaches, the method of communication can provide information to the operator with respect to operation of the moving-barrier imminent motion notification, or a transmitter identifier can provide information with respect to operation of the moving-barrier imminent motion notification.
