Twin-Post Bracing for ASRS Framework Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated storage and retrieval systems face challenges in providing a simple and flexible method for bracing their framework structures, which are prone to lateral forces and destabilizing tremors, and require external bracing that does not allow for self-standing configurations.
Innovation Solution
The implementation of a bracing arrangement using twin-post upright members with elongated bracing members that pass through spaces between the upright sections, allowing for diagonal or horizontal bracing with tensioning means to create a self-supporting framework structure without external bracing connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If external bracing connections are used to stabilize the framework structure, then structural stability is improved, but the framework cannot be self-standing and device complexity increases
Solution Approach 1:
The upright members are segmented into multiple sections (first upright member section, second upright member section) that can be independently positioned and connected. This segmentation allows the bracing members to pass through the spaces between sections, creating a modular self-standing structure without requiring external bracing connections, thus reducing device complexity while maintaining stability.
Solution Approach 2:
The bracing members are nested within the framework structure itself, passing through the spaces between upright member sections. This nesting creates an internal bracing system that provides structural stability without external connections, making the framework self-standing and reducing overall device complexity.
2Stability of the object's composition
If traditional bracing methods are used, then structural stability is improved, but ease of manufacture decreases due to external connection requirements
Solution Approach 1:
By segmenting the upright members into multiple sections with defined spaces between them, the bracing members can be pre-fabricated and then simply inserted through these spaces during assembly. This segmentation approach simplifies manufacturing and installation compared to traditional external bracing methods that require complex external connections.
Solution Approach 2:
The framework structure serves its own bracing needs through the internal arrangement of upright member sections and bracing members. The structure is self-standing and does not require external bracing connections, making it self-sufficient and easier to manufacture and install compared to systems requiring external support structures.
3Ease of operation
If the framework structure is made self-standing, then ease of operation is improved, but structural stability may be compromised without external bracing
Solution Approach 1:
The bracing members are nested within the framework structure, passing through the spaces between upright member sections to provide internal stabilization. This internal nesting creates a self-standing structure that is both flexible for operation and stable for load-bearing, eliminating the need for external bracing while maintaining both flexibility and structural integrity.
Solution Approach 2:
The bracing members extend in additional dimensions by passing through the spaces between upright member sections, creating a three-dimensional internal bracing network. This dimensional approach provides structural stability from multiple angles while maintaining framework flexibility for container handling operations.

AI summary
A bracing arrangement for a framework structure of an automated storage and retrieval system includes a plurality of upright members arranged in rows defining storage columns. The upright members support a rail system comprising first and second sets of parallel rails upon which travel container handling vehicles for retrieving containers or other items stored in the storage columns. A plurality of twin-post upright members are arranged in at least one row of the framework structure. The twin-post upright members include a pair of upright member sections arranged with a space therebetween. At least one elongated bracing member is connected at a first end to a first upper connection point and at a second end to a second lower connection point in order to brace the framework structure. Each elongated bracing member is arranged to pass diagonally through the spaces between the vertical sections of the pairs of upright member sections of the plurality of twin-post upright members arranged in the at least one row.
