Stacking Storage Notched Container Seat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking storage arrangements require complex lifting mechanisms and height adjustments for transferring containers, which can be inefficient and costly, especially when decoupling the placement and removal of containers from storage.
Innovation Solution
Incorporating a container seat with notches and transfer fingers, along with a transport device featuring rotating rollers and inclined bars, allows for seamless container transfer between the loading vehicle and storage spaces without the need for additional lifting, enabling a cost-effective and space-efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional lifting mechanisms are used for container transfer, then containers can be moved between storage spaces, but the system becomes complex and costly due to multiple height adjustments
Solution Approach 1:
The transfer fingers are positioned at the same height as the container contact surface, creating an equipotential transfer zone. This eliminates the need for lifting mechanisms during horizontal transfer, as containers can be moved between loading vehicle and transport device without vertical displacement. The holding arrangement maintains containers at a constant height, further supporting this equipotential approach.
Solution Approach 2:
The lifting function is extracted from the transfer process and consolidated into the holding arrangement and container seat, which maintain containers at a constant height throughout the transfer. The transfer fingers simply guide containers horizontally at this constant height, removing the need for complex coordinated lifting mechanisms during transfer operations.
2Productivity
If containers are transferred with height adjustments, then storage spaces at different levels can be accessed, but operational efficiency decreases due to additional lifting time
Solution Approach 1:
By maintaining container transfer at a constant height between the loading vehicle and transport device, the system eliminates time-consuming vertical movements during the critical transfer phase. The holding arrangement ensures containers remain at the same height throughout storage and retrieval operations, allowing rapid horizontal transfer without lifting delays.
3Manufacturing precision
If complex lifting mechanisms are implemented, then precise container placement is achieved, but system cost increases
Solution Approach 1:
The system achieves precise container placement by maintaining constant height through the holding arrangement and container seat, eliminating the need for complex active lifting mechanisms with sensors and controls. The transfer fingers provide passive guidance at the same height, simplifying the system while maintaining placement accuracy through geometric constraints rather than active control.

AI summary
A stacking storage arrangement includes multiple container receiving spaces, a loading space arranged below the container receiving spaces, in which the container receiving spaces are held at a first height above the loading space; and a loading vehicle movable between the loading space and a transfer region. The loading vehicle includes a container seat with a container contact surface, and the container seat is movable in a lifting direction. In the container contact surface, the container seat further includes at least two notches opening to at least one side, and at least one transfer device includes transfer fingers configured to match the notches in the container contact surface.
