Branch-Selective Channels for Point-to-Multipoint Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission rate in point-to-multipoint wired communication systems is limited due to unequal signal power distribution, leading to inefficient energy consumption and reduced signal strength at non-communicating endpoints.
Innovation Solution
A communication apparatus with channel groups featuring channels with different impedances, allowing dynamic allocation of signal power based on connectivity to source or destination nodes, ensuring higher power to connected nodes and lower power to non-connected nodes, thereby optimizing transmission rates.

Engineering Contradiction Analysis
1Productivity
If equal signal power is allocated to all channels, then simplicity of power distribution is maintained, but transmission rate for connected nodes is insufficient
Solution Approach 1:
The patent applies local quality by differentiating signal power allocation based on channel connectivity status. Channels connected to source or destination nodes receive higher signal power, while unconnected channels receive lower signal power. This localized differentiation optimizes transmission performance for active communication paths without uniformly increasing power across all channels.
Solution Approach 2:
The patent implements dynamic signal power allocation where the communication apparatus adjusts signal power per channel based on real-time connectivity information. The control unit dynamically determines which channels are connected to source/destination nodes and allocates power accordingly, enabling adaptive optimization during communication operations.
2Productivity
If higher signal power is allocated to all channels, then transmission rate improves, but energy consumption increases
Solution Approach 1:
Instead of uniformly increasing signal power across all channels, the patent applies local quality by concentrating higher power only on channels that are connected to source or destination nodes. Unconnected channels receive reduced power, thereby avoiding unnecessary energy consumption while maintaining transmission rate for active communication paths.
Solution Approach 2:
The patent converts the potential harm of high energy consumption into a benefit by using connectivity information to selectively apply power. The control unit identifies channels that would be wasted if given high power (unconnected channels) and redirects that energy to useful channels (connected to source/destination), transforming potential energy waste into optimized transmission performance.
3Productivity
If channel impedance is made equal, then manufacturing simplicity is maintained, but signal power distribution efficiency is reduced
Solution Approach 1:
The patent applies local quality to channel impedance by making the impedance of the first branch different from the second branch in selective channels. This localized impedance differentiation enables the communication apparatus to control signal power distribution efficiency without requiring all channels to have different impedances, thus balancing performance and manufacturing complexity.

AI summary
An apparatus includes one or more channel groups, each group comprising a first coupler, first channels, and second couplers. The first coupler includes a first end and second ends. One end of each of the first channels is coupled to a corresponding one of the second ends, and the other end is coupled to a corresponding one of the second couplers. The first channel includes a first branch and a second branch. An impedance of the first branch is greater than an impedance of the second branch. The first channel is used to select the first branch or the second branch, to transmit a communication signal. so that a signal of a first channel connected to a source node or a destination node flows through a low-impedance branch, and a signal of a first channel not connected to the source node or the destination node flows through a high-impedance branch.
