Wireless Event Advertisements for Timely Status Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bidirectional wireless communication systems in movable barrier systems are inefficient in conveying event-specific data, as scheduled advertisements primarily transmit ongoing status information, making it impractical to include data relevant only for a specific instance in time.
Innovation Solution
Implementing a system where a peripheral device generates event-specific advertisements in response to trigger events, transmitting these advertisements at a higher rate for a defined period and then resuming regular status advertisements once the event is concluded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scheduled advertisements are transmitted periodically to convey ongoing status information, then reliable status communication is achieved, but event-specific data cannot be conveyed effectively
Solution Approach 1:
The advertisement transmission system dynamically switches between two modes: scheduled status advertisements for ongoing information and event-triggered advertisements for specific events. The peripheral device detects trigger events and temporarily modifies the advertisement transmission behavior, pausing scheduled advertisements and transmitting event-specific advertisements with event sections when events occur, then resuming scheduled advertisements afterward.
2Loss of information
If event-specific data is included in scheduled advertisements, then event information can be transmitted, but irrelevant information is continuously transmitted wasting energy
Solution Approach 1:
The system uses periodic scheduled advertisements for status information and event-triggered periodic transmission for event-specific data. When a trigger event is detected, the peripheral device transmits event-specific advertisements at event-specific intervals for a predetermined duration, then returns to the scheduled periodic transmission pattern.
Solution Approach 2:
The advertisement structure is extracted into separate components: status sections containing ongoing status information and event sections containing event-specific data. The event section is only included in advertisements transmitted during event-specific intervals, separating relevant event information from routine status updates.
3Speed
If advertisement transmission rate is increased for event-specific data, then timely communication is achieved, but processing load on receiving devices increases
Solution Approach 1:
The advertisement transmission rate dynamically adjusts based on event conditions. During event-specific intervals, advertisements are transmitted at event-specific intervals (faster rate) to ensure timely communication. During normal scheduled intervals, advertisements are transmitted at scheduled intervals (slower rate) to reduce processing load on receiving devices.

AI summary
A method for communicating status and event information between a first device and a second device. The method includes the first device transmitting a status advertisement to the second device at a first transmission rate. The method further includes the first device detecting a trigger event triggering modified communication with the second device and generating an event advertisement including an event section corresponding to the trigger event. The method further includes the first device transmitting, to the second device, the event advertisement at a second transmission rate for a predetermined duration of time. The method further includes the first device, in response to the predetermined duration of time ending, resuming transmitting the status advertisement to the second device at the first transmission rate.
