RF Transmitter Sequential Counter Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rolling-code based transmit/receive systems require multiple user inputs for training, leading to user errors and incomplete synchronization, resulting in system malfunction and unnecessary manufacturer support requests.
Innovation Solution
A radio frequency transmitter configured to send at least two sequential encrypted counter values in response to a single user input, simplifying the training process and ensuring proper synchronization with the receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmitter sends only one encrypted counter value in response to a single user input, then the system maintains security through rolling code, but the training process becomes complex and error-prone requiring multiple button presses
Solution Approach 1:
The transmitter pre-generates and queues multiple sequential encrypted counter values (at least two) in advance, so that when a user presses the button during training, the transmitter automatically sends the first counter value, then immediately sends the second counter value without requiring another button press. This preliminary preparation of multiple counter values resolves the contradiction by making training reliable (ensuring synchronization) while simplifying operation (single button press).
2Reliability
If the user must press the transmitter button multiple times to complete training, then proper synchronization can be achieved, but the time required for training increases and user frustration increases
Solution Approach 1:
The transmitter continuously sends encrypted counter values in sequence without interruption during the training process. After the user presses the button once, the transmitter sends the first counter value, then automatically sends the second counter value in immediate succession, maintaining continuous useful action. This eliminates the need for users to wait between multiple button presses, reducing training duration while ensuring synchronization accuracy is maintained through the sequential counter values.
3Ease of operation
If the transmitter sends sequential counter values automatically, then the training process is simplified, but the device complexity increases
Solution Approach 1:
The transmitter is programmed to automatically manage the sequence of encrypted counter values without user intervention. The device self-services by detecting when it is in training mode, automatically generating and queuing multiple sequential counter values, and transmitting them in the correct sequence without requiring the user to understand or manage the complexity. This internal automation simplifies operation for the user while containing the complexity within the transmitter's control logic.

AI summary
A radio frequency transmitter is configured to send radio frequency messages to activate a remote system. Each message includes an encrypted counter value and a transmitter identifier. The transmitter is configured to send at least two of the messages having sequential encrypted counter values in response to a single user input.
