Integrated Frame Member Outlets for 3D Grid Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression systems in automated storage and retrieval systems are not effectively suited for densely packed three-dimensional grids, as ceiling sprinklers may not reach containers in the center, and traditional systems are complex and costly to implement.
Innovation Solution
An elongate frame member with a conduit and outlets is integrated into the framework of the system, allowing direct fluid delivery to storage columns, including fire suppressants or environmental compositions, without the need for external piping, and featuring passive actuation for fire detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ceiling sprinklers are used for fire suppression, then fire suppression capability is provided, but the system cannot effectively reach containers in the center of densely packed three-dimensional grids
Solution Approach 1:
The fire suppression system is segmented by integrating conduits and outlets directly into the frame members that form the three-dimensional grid structure. This distributes fluid delivery points throughout the grid volume, ensuring coverage of containers in the center and all peripheral areas, rather than relying on a single ceiling-based sprinkler system.
Solution Approach 2:
The patent transitions from a two-dimensional ceiling-based sprinkler system to a three-dimensional distributed outlet system embedded within the grid frame members. This spatial redistribution of outlets across multiple dimensions ensures comprehensive fluid delivery coverage throughout the entire storage volume, including centrally located containers.
2Reliability
If traditional fire suppression systems are implemented, then fire safety is provided, but the system becomes complex and costly to implement
Solution Approach 1:
The patent merges the fire suppression fluid delivery function with the existing frame members that support the automated storage and retrieval system. By integrating conduits and outlets into the structural frame, the design eliminates the need for separate external piping systems, reducing overall system complexity and implementation cost while maintaining fire safety functionality.
Solution Approach 2:
The frame members of the automated storage system are given multiple functions: they provide structural support for containers and simultaneously serve as conduits for fire suppressant delivery. This multi-functionality reduces the number of separate components needed, simplifying the overall system design and reducing costs.
3Ease of operation
If external piping is used for fluid delivery, then fluid can be delivered to storage columns, but the installation becomes complex and costly
Solution Approach 1:
The patent combines the fluid delivery conduits with the frame members themselves, eliminating the need for separate external piping. The conduits are integrated into the frame structure during manufacturing, which simplifies installation by removing the need for complex piping routing and connection work while maintaining effective fluid delivery capability.

AI summary
The disclosure relates to an elongate frame member for use in a frame of an automated storage and retrieval system. The frame defines a plurality of storage columns for receiving stacks of storage containers. The elongate frame member comprises: a conduit for carrying fluid; and at least one outlet at a longitudinal surface of the elongate frame member. Each outlet is in communication with the conduit. The outlet is arranged to deliver the fluid from the conduit into the automated storage and retrieval system. The conduit is housed within the elongate frame member.
