Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale industrial wireless networks face challenges in communication load and limited wireless band resources, making it difficult to build and maintain networks with a large number of connected devices due to increased packet transmission and reception demands.
Innovation Solution
A wireless relay device aggregates multiple data packets addressed to the same device, reducing the total data amount transmitted over the network, thereby alleviating communication load and resource scarcity by generating a single aggregated packet for transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of field devices is increased to build a large wireless network, then the network scale and coverage are improved, but the communication load of wireless relay devices increases
Solution Approach 1:
The patent applies data aggregation by merging multiple data packets into a single aggregated packet at wireless relay devices. This combining of data from multiple field devices reduces the total number of packets transmitted through the network, thereby decreasing communication load on relay devices while maintaining the ability to support a large number of field devices.
2Quantity of substance
If the number of field devices is increased to build a large wireless network, then the network scale and coverage are improved, but the wireless band resources become scarce
Solution Approach 1:
The patent combines multiple data packets into aggregated packets, reducing the total data volume transmitted over wireless bands. This merging approach optimizes wireless band utilization by minimizing redundant transmissions and reducing the overall consumption of wireless communication resources.
3Adaptability or versatility
If the number of wireless devices is increased to expand network capacity, then the network coverage is improved, but the device complexity and resource management become more difficult
Solution Approach 1:
The patent implements data aggregation that automatically combines packets from multiple sources, simplifying resource management by reducing the number of individual packet handling operations. This approach maintains high network capacity while reducing the complexity of packet routing, forwarding, and resource allocation management.
