Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication relay devices lack flexibility in switching between external networks, particularly in mobile settings where automatic selection is desired but not always feasible, and users face challenges in selecting optimal networks manually, leading to inconvenient and unreliable connections.
Innovation Solution
A communication connection device equipped with network selection processing and re-selection mechanisms, using profile information to automatically select and re-select external networks based on priority, signal strength, and availability, with a user-operable switch for manual intervention, enabling optimal network choice at arbitrary times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic network selection is implemented using fixed algorithms, then network switching is automated, but flexibility to change selection criteria is lost
Solution Approach 1:
The patent implements dynamic network selection by allowing the device to automatically switch between manual and automatic selection modes. The network selection unit can dynamically change selection criteria based on whether it is in manual or automatic mode, and can further adapt within automatic mode between different algorithms (signal strength-based or load-based). This resolves the contradiction by making the system both automated and flexible through dynamic mode switching and adaptive algorithm selection.
2Ease of operation
If manual network selection is used, then user control is maximized, but automation and convenience are reduced
Solution Approach 1:
The patent implements self-service by enabling the device to automatically perform network selection tasks without user intervention. When in automatic selection mode, the network selection unit autonomously monitors network conditions, evaluates available networks based on configured criteria (signal strength or load), and switches networks automatically. This resolves the contradiction by allowing the system to serve itself in automatic mode while preserving user control capability when needed.
3Stability of the object's composition
If a device is designed for fixed position installation, then connection stability is improved, but mobility and adaptability to different networks are reduced
Solution Approach 1:
The patent makes the connection behavior dynamic by implementing both stable fixed-mode operation and adaptive mobile-mode operation. The network selection unit can maintain stable connections when in manual mode or when connected to a preferred network, while simultaneously being capable of automatic network switching when mobility is required. The system adapts its behavior based on the operational context, resolving the contradiction between stability and adaptability.
