Daisy-Chain Connection Device Data Suppression Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In daisy-chain-connected multi-device networks, existing solutions require intermediate nodes to store data and determine whether to transmit it, leading to increased costs for memories and additional examination costs, making efficient signal transfer between devices challenging.
Innovation Solution
A connection device with a communication line, a data generating section, a data input section, and a data suppressing section that prevents data from being sent to downstream devices, using a comparator to control data flow and reduce unnecessary data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate nodes store data and determine whether to transmit it to downstream devices, then data transmission control is achieved, but extra parts costs for memories and additional examination costs become necessary
Solution Approach 1:
The patent extracts the data transmission control function from intermediate nodes by removing the need for memory storage and examination logic. Instead, the upstream device generates suppression data that is transmitted through the daisy-chain, and each node simply forwards this suppression data without processing or storing it, thereby eliminating the need for additional memory components and examination costs while maintaining reliable data transmission control.
Solution Approach 2:
The patent introduces suppression data as an intermediary control mechanism. This suppression data acts as a mediator that travels through the daisy-chain connected devices, enabling upstream devices to control downstream data transmission without requiring intermediate nodes to have memory or decision-making capabilities. The suppression data effectively mediates the data flow control across the entire chain.
2Adaptability or versatility
If data is transmitted to all nodes in a daisy-chain-connected network, then communication coverage is maximized, but unnecessary data transmission to unintended devices occurs
Solution Approach 1:
The patent applies preliminary action by having the upstream device generate and transmit suppression data before the actual data transmission occurs. This suppression data is propagated through the daisy-chain in advance, establishing control parameters for each node. When data transmission occurs, nodes can immediately determine whether to forward or block the data based on the pre-established suppression data, preventing unnecessary energy consumption from transmitting data to unintended devices while maintaining comprehensive communication coverage.
Solution Approach 2:
The patent implements local quality by enabling each node in the daisy-chain to have different data forwarding characteristics based on the suppression data received. Each node independently determines its own data transmission behavior according to the local suppression data parameters, allowing precise control over which nodes receive and forward data versus which nodes block data, thereby eliminating unnecessary transmissions while maintaining appropriate communication coverage for each segment of the network.

AI summary
It is made possible to favorably perform signal transfer between a plurality of daisy-chain-connected devices. There is a communication line for performing communication between a first electronic device and a second electronic device. A data generating section generates first data to be transmitted to the first electronic device. Then, a data input section inputs the first data to a first position on the communication line. In addition, a first data suppressing section is provided at a second position on the communication line, the second position being closer to the second electronic device than the first position is, and the first data suppressing section prevents the first data from being sent to the second electronic device.
