Gateway Manager Coupling for Mobile Device Feedback Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial automation systems with star topology, mobile communication devices like self-powered wireless push buttons lack immediate feedback confirmation when out of range of their paired gateway, leading to lost messages and user uncertainty.
Innovation Solution
A method and system utilizing a gateway manager to identify and locate mobile communication devices based on quality metrics, dynamically couple them with feedback devices, and send feedback signals, ensuring contextual confirmation of commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a star topology network is used with fixed gateway pairing, then packet transmission efficiency is improved, but mobile communication device feedback reliability deteriorates when out of range
Solution Approach 1:
The patent implements dynamic gateway coupling where the feedback device is dynamically associated with different gateways based on the mobile communication device's current location and signal quality metrics, rather than being statically paired with a single gateway. This allows the system to adapt to changing network conditions and maintain reliable feedback delivery.
Solution Approach 2:
The patent introduces a feedback device as an intermediary element that receives commands from mobile communication devices and provides visual or audible confirmation to users. This intermediary ensures reliable feedback delivery even when the mobile device is out of range of its originally paired gateway, by allowing the feedback device to be coupled with different gateways based on current network conditions.
2Device complexity
If a single function device broadcasts messages without feedback capability, then device complexity is reduced, but user confidence deteriorates due to lack of immediate confirmation
Solution Approach 1:
The patent implements a feedback mechanism where feedback devices (such as visual LEDs or audible speakers) provide immediate confirmation to users when their commands are received. The feedback device receives the command from the mobile communication device and generates a visible or audible signal, ensuring the user receives confirmation without adding complexity to the communication device itself.
Solution Approach 2:
The patent separates the feedback function from the communication device by using an independent feedback device. This segmentation allows the simple mobile communication device to maintain its low complexity while the feedback functionality is provided by a separate component that can be visually or auditorily observed by the user.
3Adaptability or versatility
If all packets must go through the gateway, then network control is improved, but network bottlenecking increases at the gateway
Solution Approach 1:
The patent implements a hybrid approach where feedback messages (which are small and frequent) can be transmitted directly between mobile communication devices and feedback devices without passing through the gateway, while other critical control traffic still routes through the gateway. This partial bypass reduces gateway bottlenecking for feedback traffic while maintaining gateway control for important network operations.

AI summary
A method for managing single function devices among communication devices broadcasting messages to gateways connected to a gateway manager, a single function device being only able to broadcast a message including a command. The method comprises: the gateways receiving messages sent from communication devices, each message containing an identifier of communication device, the gateways determining quality metrics for each received message, the quality metrics pertaining to the radio link between the gateway and the communication device, the gateways storing, for each received message, a property vector comprising the identifier of the communication device and the quality metrics, the gateway manager collecting the property vectors from all the gateways, the gateway manager identifying a single function device by detecting a property vector comprising an identifier of communication device that is included in a list of single function devices, the gateway manager determining a location of the identified single function device based on the quality metrics of the detected property vector, the gateway manager coupling the identified single function device with a feedback device, based on the determined location of the single function device and on a location of the feedback device, and the gateway manager sending an order to the coupled feedback device to perform a feedback signal.
