Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing serial network topologies are limited in their ability to connect multiple rows of node devices in bidirectional configurations, requiring the network to double back and increase in length and space requirements due to fixed orientation of select lines at each node.
Innovation Solution
The configuration of select line connections at each node device to function as input or output lines based on detection of a selection event, allowing for bidirectional communication and reducing the need for network doubling by supporting multiple directional connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed orientation of select lines at each node is used, then simple node configuration is achieved, but network length and space requirements increase due to doubling back
Solution Approach 1:
The patent applies dynamics by making the select line connections configurable rather than fixed. Each node device can dynamically switch between different connection configurations (first configuration and second configuration) depending on the desired communication direction. This dynamic reconfigurability allows the network to adapt its topology, eliminating the need for doubling back and reducing overall network length while maintaining simple node configurations.
Solution Approach 2:
The patent changes the parameter of select line connection orientation from fixed to variable. By enabling nodes to switch between first and second configurations, the system can optimize the physical layout and routing of the serial network. This parameter change allows multiple rows of node devices to be connected in bidirectional configurations without requiring the network to double back, thereby reducing space requirements and network length.
2Device complexity
If fixed orientation of select lines at each node is used, then simple node configuration is achieved, but bidirectional communication capability is limited
Solution Approach 1:
The patent enables dynamic reconfiguration of select line connections at each node device. Nodes can switch between first configuration (connecting first select line connection to first line and second select line connection to second line) and second configuration (connecting first select line connection to second line and second select line connection to first line). This dynamic capability allows the network to support bidirectional communication efficiently without increasing node configuration complexity.
Solution Approach 2:
The patent makes each node device universal by enabling it to function in multiple communication directions. Through configurable select line connections, each node can adapt to different communication scenarios and connect to multiple rows of node devices in various directions. This multi-functionality enhances bidirectional communication capability while maintaining simple node configurations.
3Adaptability or versatility
If network doubling is implemented to connect multiple rows, then connectivity is achieved, but physical space requirements increase
Solution Approach 1:
The patent changes the connection parameter at each node to be configurable rather than fixed. By switching between first and second configurations, nodes can optimize the physical routing of the serial network. This allows multiple rows of node devices to be connected in compact bidirectional configurations, eliminating the need for network doubling and significantly reducing physical space requirements while maintaining full connectivity capability.
Solution Approach 2:
The patent applies dynamics by enabling flexible reconfiguration of network topology. Nodes can adapt their connection configurations based on the desired communication direction and physical layout requirements. This dynamic topological adaptation allows efficient space utilization and eliminates the need for space-consuming network doubling to achieve connectivity between multiple rows of nodes.

AI summary
For a bi-directional bus topology, a node connection includes two select line connections for a select line of a serial network. The select line is broken at the node connection. A bus direction module configures a first select line connection for an input line and a second select line connection for an output line in response to detecting a selection event. At least a portion of the bus direction module includes one or more of hardware and executable code, the executable code stored on a memory.
