Wireless Readvertising for Multi-Operator Barrier Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional remote-controlled movable barrier systems lack bidirectional communication connections between the controlling device and the operator, preventing secure operational commands and data transfer, and cannot control multiple operators simultaneously with a single activation.
Innovation Solution
A readvertising operation is performed by the controlling device to establish bidirectional wireless connections with multiple movable barrier operators, using unique identifiers (UIDs) to recognize and connect with the first requesting operator, and subsequently ignore or retransmit signals to unconnected operators until all are controlled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bidirectional communication connection is formed between the controlling device and the operator, then secure operational commands and data transfer are enabled, but the device complexity increases due to the need for connection management and authentication protocols
Solution Approach 1:
The patent applies preliminary action by pre-establishing bidirectional communication connections between the controlling device and multiple operators before operation. The system proactively forms encrypted connections and maintains them ready for immediate command transmission, rather than establishing connections on-demand. This ensures security is already in place when commands need to be sent.
Solution Approach 2:
The patent uses an intermediary approach by introducing a connection management layer that handles authentication, encryption, and connection maintenance between the controlling device and operators. This intermediary layer abstracts the complexity of secure communication protocols from the core control functionality, managing the overhead of bidirectional connections systematically.
2Productivity
If traditional unidirectional transmission is used, then the device complexity is low, but multiple operators cannot be controlled simultaneously with a single activation
Solution Approach 1:
The patent applies segmentation by dividing the control process into distinct phases: connection establishment phase, command transmission phase, and acknowledgment receipt phase. The controlling device segments its communication with multiple operators into sequential connection formations, establishing one bidirectional connection at a time while managing multiple operators. This allows simultaneous control capability while breaking down the complexity into manageable segments.
Solution Approach 2:
The patent uses periodic action by implementing cyclic connection establishment and command transmission sequences. The controlling device periodically attempts to form connections with operators in sequence, transmits commands to connected operators, and receives acknowledgments in a repeating cycle. This periodic operation enables simultaneous control of multiple operators through structured, repeating communication patterns.
3Productivity
If connection establishment attempts are made with all operators simultaneously, then all operators can be controlled, but connection conflicts and delays occur
Solution Approach 1:
The patent implements periodic action by using cyclic connection establishment attempts with defined intervals. Instead of simultaneous connection attempts, the controlling device systematically cycles through operator connection requests at controlled time intervals. This periodic approach reduces connection conflicts and establishes connections more efficiently than random or simultaneous attempts.
Solution Approach 2:
The patent applies preliminary action by pre-screening operators and prioritizing connection establishment with operators that are most likely to respond or have the highest priority. The system prepares connection requests in advance and attempts connections in a predetermined sequence, reducing the overall time required to establish connections with multiple operators compared to random simultaneous attempts.

AI summary
An advertising device for performing a readvertising operation for wirelessly connecting with a plurality of connecting devices. The advertising device transmits an advertising signal for establishing connection with the plurality of connecting devices. In response, the advertising device receives a plurality of connection requests from the plurality of connecting devices and transmits a first connection response to the first discernable connection request that was received from a first connecting device of the plurality of connecting devices, thereby establishing a first wireless connection between the advertising device and the first connecting device. In response to establishing the first wireless connection, the advertising device retransmits the advertising signal to establish connection with the others of the plurality of connecting devices.
