Overhead Storage Rack Layout for Dense Grid-Based Article Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead storage systems face inefficiencies in storing a large number of articles without upsizing the system.
Innovation Solution
An overhead storage system with a rail-guided vehicle that travels on a grid-patterned rail, featuring a body section to hold articles below the rail, a storage rack for article placement, and a control unit to manage operations, including a transfer device capable of transferring articles to and from storage areas defined by a matrix of cells in the grid pattern, preventing jutting into adjacent cells during transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional storage units are placed on the floor, then accessibility is improved, but floor space is wasted
Solution Approach 1:
The storage system transitions from floor-level placement to vertical wall-mounted placement, utilizing the vertical dimension to store items. This allows floor space to be freed up while maintaining accessibility through strategic positioning of storage units at various heights and locations on walls, doors, or partitions.
2Quantity of substance
If storage space is increased, then storage capacity is improved, but device complexity increases
Solution Approach 1:
The storage system is divided into multiple independent storage units that can be individually selected, removed, cleaned, or replaced. Each unit functions independently, allowing the system to scale in capacity without proportionally increasing overall system complexity. Users can configure the number and type of storage units based on specific needs.
Solution Approach 2:
The storage units are designed with universal compatibility to be mounted on various surfaces including walls, doors, and partitions. The same basic unit design can serve multiple functions and be positioned in multiple locations, increasing storage capacity without requiring proportionally more complex system architecture.
3Ease of operation
If storage units are made accessible, then ease of operation is improved, but risk of dropping items increases
Solution Approach 1:
The storage units incorporate removable lids that can be opened for access and closed for protection. This dynamic element allows the system to transition between accessible and protected states, enabling easy retrieval of items while preventing accidental drops when the lids are closed. The lids provide a simple mechanical solution to reduce dropping risk without compromising accessibility.

AI summary
An overhead storage system includes: an overhead transport vehicle including a traveling unit configured to travel on a rail arranged in a grid pattern and a body section suspended from the traveling unit and configured to hold an article below the rail; a storage rack disposed below the rail; and a control unit configured to control operation of the overhead transport vehicle. The body section includes a transfer device capable of transferring the article to and from the storage rack. In the storage rack, a plurality of article placement areas on which the article is able to be placed by the transfer device are set in a storage area corresponding to each of cells forming a matrix in the grid pattern of the rail.
