Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in control and network applications face inefficiencies in routing communications among multiple devices, particularly in one-to-many topologies, where direct communication paths are not always optimal and redriver modes are not effectively utilized to manage data transmission across bus traces.
Innovation Solution
A system and method that includes a controller connected to logic circuits and devices, capable of detecting communications and selectively activating direct communication paths and redriver paths between devices, allowing for efficient point-to-point communication with target devices while enabling non-target devices to receive data copies through redriver mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct communication paths are used for all devices in a one-to-many topology, then communication speed is improved, but device complexity and power consumption increase
Solution Approach 1:
The communication system is segmented into two distinct modes: direct communication mode for point-to-point transmissions and redriver mode for broadcast transmissions. The controller segments the routing logic by identifying target devices and selectively activating appropriate communication paths, thereby reducing overall system complexity while maintaining high-speed communication capabilities when needed.
Solution Approach 2:
The system dynamically switches between direct communication mode and redriver mode based on the communication target. The controller detects the target device and dynamically reconfigures the communication path, allowing the system to adapt its complexity level to the specific communication requirement rather than maintaining fixed high-complexity routing for all scenarios.
2Adaptability or versatility
If redriver mode is used for all communications, then device compatibility is improved, but communication efficiency deteriorates
Solution Approach 1:
The system dynamically selects between redriver mode and direct communication mode based on the target device identification. For point-to-point communications, the system switches to direct mode to achieve high efficiency, while for broadcast or incompatible devices, it uses redriver mode to ensure compatibility. This dynamic adaptation resolves the contradiction between universal compatibility and optimal efficiency.
Solution Approach 2:
The communication mode parameter is changed based on the target device and communication requirements. The controller detects the target device and changes the operational parameter from fixed redriver mode to a variable state that selects direct mode for efficiency when appropriate, thereby optimizing productivity while maintaining adaptability.
3Use of energy by moving object
If direct communication mode is activated for point-to-point communication, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The control logic is segmented into distinct detection and activation functions. The controller detects the target device, determines the appropriate mode, and activates only the necessary communication path. This segmentation of control functions reduces the overall complexity burden while enabling power-efficient direct communication mode selection.
Solution Approach 2:
The controller automatically detects target devices and self-determines the appropriate communication mode without external intervention. This self-service capability simplifies the user interface complexity while enabling power-efficient operations through automatic mode selection between direct and redriver modes.

AI summary
Systems and methods for routing communication among a plurality of devices are described. In an example, a controller can detect a communication initiated from a first device to a target device among a second device and a third device. The controller can identify the second device as the target device. The controller can, in response to identifying the second device as the target device, activate a direct communication path between the first device and the second device to allow the first device to communicate with the second device using direct communication mode. The controller can, in response to identifying the second device as the target device, activate redriver path between the first device and the third device to allow the first device to communicate with the third device using redriver mode.
