Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between a cloud server and devices within a LAN face inefficiencies due to duplication of device management among multiple gateways, leading to resource waste and ineffective device management.
Innovation Solution
A communication system with multiple communication relay apparatuses that perform a device search process, acquire management target device information, and determine unique management target devices by excluding duplicates based on management device information, ensuring efficient device management by removing partial duplication among gateways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple gateways independently determine management target devices without coordination, then device search and management capability is improved, but device duplication and resource waste occurs
Solution Approach 1:
The patent combines the device search results from multiple gateways and merges them into a unified management target device list. By integrating the search capabilities of multiple gateways and consolidating their results, the system achieves comprehensive device management while eliminating duplication through centralized coordination.
Solution Approach 2:
The patent creates a unified view of management target devices by copying and consolidating device information from multiple gateway search results. Instead of each gateway independently managing devices, the system creates a shared repository of device information that all gateways can access, eliminating redundant management overhead.
2Adaptability or versatility
If multiple gateways independently determine management target devices, then device search coverage is improved, but management efficiency deteriorates due to duplication
Solution Approach 1:
The patent merges the device search capabilities of multiple gateways into a coordinated system. By combining search results and eliminating duplicates, the system achieves comprehensive device coverage while maintaining efficient management through centralized coordination rather than independent redundant operations.
Solution Approach 2:
The patent creates a universal device management mechanism that serves all gateways simultaneously. The unified management target device determination process provides a multi-functional solution that enables all gateways to access and manage devices efficiently, rather than each gateway requiring independent device determination capabilities.
3Reliability
If gateways establish message sessions with management server for each device access, then access control and security is improved, but communication overhead and time consumption increases
Solution Approach 1:
The patent performs preliminary device search and management target determination at system initialization or before access operations. By pre-establishing the relationships between gateways and management target devices, the system avoids repeated communication overhead during actual device access operations while maintaining security through the management server.
Solution Approach 2:
The patent implements local caching of device information and management target relationships at each gateway. Instead of querying the management server for every access operation, gateways store locally the device search results and management target determinations, reducing communication time while maintaining access control through periodic updates from the management server.

AI summary
A communication system includes a plurality of communication relay apparatuses relaying communication between the plurality of devices provided inside a LAN and an external server provided outside the LAN. A first communication relay apparatus performs a device search process of searching the LAN for a device, acquires information on a first management target device which is a device whose communication relay process is managed by a second communication relay apparatus, and determines a second management target device which is a device whose communication relay process is managed by the first communication relay apparatus. The first communication relay apparatus determines the second management target device after removing at least partial duplication of the second management target device and the first management target device, by excluding at least some of the first management target device from two or more devices which are retrieved in the device search process.
