Domestic Appliance Communication Module Dual Data Transmission Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household appliances with communication modules can only transmit data at either low or high rates, not simultaneously, due to limitations in their internal communication structures.
Innovation Solution
Implementing at least two separate data transmission channels within the appliance, allowing for simultaneous data transmission at different rates, with one channel for high-throughput multimedia data and another for low-throughput control data, using various connection types such as RS-485 and SPI buses or direct master-slave connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single data transmission channel is used in the household appliance, then the device complexity is reduced, but the ability to transmit data at different rates simultaneously is lost
Solution Approach 1:
The internal communication structure is segmented into multiple independent data transmission channels (first data transmission channel and second data transmission channel), each capable of operating at different data rates. This segmentation allows the communication module to simultaneously transmit different types of data at different rates, resolving the contradiction between adaptability and complexity by organizing the communication structure into modular, independent pathways.
Solution Approach 2:
The patent introduces an additional dimension to the communication structure by adding a second data transmission channel that operates independently from the first. This dimensional expansion enables simultaneous data transmission at different rates, transforming the system from a single-rate pathway to a multi-rate parallel architecture, thereby achieving adaptability without excessive complexity.
2Productivity
If data is transmitted at high data rates, then the productivity of data transmission is improved, but the ability to maintain stable communication for control functions is compromised
Solution Approach 1:
Different data transmission channels are assigned different quality characteristics appropriate to their specific functions. The first data transmission channel is optimized for high data rates to handle multimedia content efficiently, while the second data transmission channel is optimized for stability and reliability to handle control commands. This local quality differentiation allows each channel to excel at its specific task, resolving the contradiction between productivity and reliability.
3Quantity of substance
If a single communication channel is used, then the device complexity is reduced, but the quantity of data that can be transmitted simultaneously is limited
Solution Approach 1:
The patent merges multiple data transmission channels with different characteristics into a unified communication architecture. The first and second data transmission channels are combined within the same household appliance communication structure, allowing simultaneous transmission of different data types at different rates. This merging approach increases the total data transmission volume capability while maintaining a structured, manageable communication system.
