Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated materials handling environments, such as factories and warehouses, wireless communication for autonomous devices like AGVs is unreliable due to network interference, metallic obstacles, and varying connectivity needs, leading to unacceptable downtimes and operational disruptions.
Innovation Solution
An autonomous device with a programmable framework (NiX) that supports multiple wireless access interfaces, dynamically selects the best network based on SLA requirements, using KPI-driven network control to ensure reliable communication by compiling SLAs into KPIs, measuring, and routing data through a data-driven automation routing agent, network control software, and centralized management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used for autonomous devices in automated materials handling environments, then mobility and operational flexibility are improved, but communication reliability deteriorates due to network interference, metallic obstacles, and varying connectivity needs
Solution Approach 1:
The autonomous device is equipped with multiple wireless access interfaces (Wi-Fi, Bluetooth, cellular, etc.) that can function independently or in combination. This multi-functionality allows the device to adapt to different connectivity requirements while maintaining reliable communication by selecting the most appropriate interface based on environmental conditions and service level agreements.
Solution Approach 2:
The system dynamically selects and switches between different wireless access interfaces based on real-time key performance indicator data and service level agreement requirements. This dynamic adaptation enables the device to maintain reliable communication despite changing environmental conditions such as network interference and metallic obstacles.
2Reliability
If multiple wireless access interfaces are supported for dynamic selection, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The autonomous device autonomously evaluates key performance indicator data from multiple wireless access interfaces and automatically selects the most appropriate interface without requiring manual intervention or complex external control systems. This self-service approach manages the complexity of multiple interfaces through automated decision-making based on predefined service level agreements and real-time performance data.
3Reliability
If dynamic interface selection based on KPI evaluation is implemented, then communication reliability is improved, but processing time and computational resources increase
Solution Approach 1:
The system pre-establishes service level agreements and defines key performance indicator thresholds before operational needs arise. By having these criteria predetermined, the autonomous device can quickly evaluate available wireless interfaces and make selection decisions without extensive real-time analysis, thereby minimizing handover time while maintaining communication reliability.
