Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated storage and retrieval systems lack reliable information on the location of heat or fume emissions, making it difficult for firefighting crews to identify the source of fires accurately.
Innovation Solution
Implementing a rail system with remotely operated vehicles equipped with fire detection devices that transmit data to a master control system, which processes this information to create a heat map or verify the location of emissions, using a combination of fire detection devices to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fixed fire detection systems are used in automated storage and retrieval systems, then the system structure remains simple, but the ability to locate heat or fume emissions accurately is insufficient
Solution Approach 1:
The patent transforms the fire detection system from a static fixed installation to a dynamic mobile system. Remotely operated vehicles equipped with fire detection devices move throughout the automated storage and retrieval system, dynamically positioning detection capabilities where needed. This allows accurate location identification of heat or fume emissions while maintaining operational flexibility.
Solution Approach 2:
The remotely operated vehicles serve as intermediaries between the fire detection devices and the master control system. These vehicles carry detection equipment to various locations, transmit data to the control system, and enable the system to locate emissions without requiring fixed detectors throughout the entire facility.
2Measurement precision
If multiple fire detection devices are deployed to improve location accuracy, then the measurement precision increases, but the device complexity and cost increase
Solution Approach 1:
The remotely operated vehicles serve multiple functions: they perform normal storage and retrieval operations while simultaneously carrying fire detection devices. This multi-functionality allows the system to achieve comprehensive fire detection coverage without adding dedicated detection infrastructure, thereby improving measurement precision without proportionally increasing device complexity.
Solution Approach 2:
Instead of deploying multiple fixed detectors simultaneously throughout the system, the patent uses mobile detectors that can be dynamically positioned. A single remotely operated vehicle with detection equipment can service multiple locations sequentially, achieving the same coverage as multiple fixed devices would provide, but with reduced overall system complexity.
