Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If daisy chain connection is used to reduce wiring complexity, then wiring complexity is reduced, but signal connection between electronic devices is not properly established
Solution Approach 1:
The terminal is divided into multiple channels, with each channel capable of independent signal transmission. This segmentation allows proper signal connection between devices while maintaining the simplified daisy chain wiring structure, resolving the contradiction between reduced wiring complexity and reliable signal connection.
Solution Approach 2:
Different channels within the terminal are assigned specific connection functions (e.g., channel 1 for upstream, channel 2 for downstream). This local differentiation enables proper signal routing between adjacent devices in the daisy chain while keeping the overall wiring simple.
2Ease of operation
If channel numbers are shifted by one for multistage connection, then multi-tile display can be completed without input channel setting, but signal connection between electronic devices is not involved
Solution Approach 1:
The terminal channels are segmented into different functional groups (upstream channels and downstream channels). This segmentation enables automatic channel assignment in multistage connections while simultaneously establishing proper signal connections between adjacent devices, resolving both ease of operation and signal connection reliability.
Solution Approach 2:
Each terminal is designed with multiple channels that can serve different functions depending on the connection configuration. This multi-functionality allows the same terminal structure to handle both simple daisy chain connections and complex multistage connections with proper signal routing, improving ease of operation without sacrificing signal connection reliability.
3Adaptability or versatility
If additional electronic devices are added to the daisy chain, then device functionality is enhanced, but signal connection reliability is affected when devices are turned off
Solution Approach 1:
The terminal channels are segmented into upstream and downstream groups that can independently function. This segmentation allows the daisy chain to maintain signal connections even when intermediate devices are turned off, as the upstream channels can still transmit signals through inactive devices to downstream devices, enhancing both adaptability and connection reliability.

AI summary
A signal connection is properly made between electronic devices in daisy chain connection.An electronic device includes a first terminal and a second terminal for daisy chain connection. The first terminal and the second terminal each have a plurality of channels. Some of the channels of the first terminal are shifted and directly connected to some of the channels of the second terminal. For example, communication circuits (a transmit/receive circuit, a transmitting circuit, or a receiving circuit) are connected to other channels of the first terminal and other channels of the second terminal.
