Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network applications for home automation, such as infrared, Bluetooth, and Wi-Fi, are limited in controlling devices one-to-one and have restricted transmission distance and direction, making it difficult to transmit remote control signals effectively over long distances using mesh networks.
Innovation Solution
A method and remote control system that utilizes a mesh network control device and an infrared control device to divide control instructions into transmission codes, transmit them via a mesh network, and restore them to control household appliances using infrared signals, thereby overcoming packet length limitations and extending control distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If control instructions are transmitted directly via mesh network, then transmission distance and direction are limited, but packet length limitation prevents effective long-distance control
Solution Approach 1:
The patent segments long control instructions into multiple shorter transmission codes that comply with mesh network packet length limitations. Each transmission code is a portion of the original control instruction, allowing the complete instruction to be reconstructed at the receiving end through concatenation of multiple received segments.
2Ease of operation
If traditional infrared, Bluetooth or Wi-Fi connections are used, then one-to-one control is simple, but transmission distance and direction are restricted
Solution Approach 1:
The patent introduces mesh network nodes as intermediaries to relay control signals between the controller and controlled devices. Instead of direct one-to-one transmission, the mesh network provides multi-hop routing capability, allowing signals to traverse through multiple intermediate devices to reach distant targets while maintaining controlled device complexity.
3Reliability
If control instructions are divided into transmission codes, then packet length limitation is overcome, but device complexity increases
Solution Approach 1:
The patent performs preliminary segmentation of control instructions into transmission codes before transmission. This pre-processing step prepares the data in a format suitable for mesh network packet length constraints, and the receiving device performs corresponding reassembly operations to reconstruct the original control instruction.
