Replaceable Battery Charging Layout for Grid Storage Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated storage and retrieval systems face operational downtime due to the need for vehicle recharging, which reduces the system's operational cycle and is accompanied by space and stability issues with current power supply arrangements, as well as complex and prone-to-failure hook systems.
Innovation Solution
The system incorporates a track-based power supply compartment in the container handling vehicle with a replaceable power supply and a charging station that allows for efficient charging without reducing storage space or stability, using a power supply support mechanism that ensures reliable coupling and prevents lateral movement during charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a power supply is installed in the container handling vehicle, then the vehicle can operate autonomously, but the vehicle requires recharging which causes operational downtime
Solution Approach 1:
The charging station enables continuous operation by charging the vehicle's power supply during idle periods when the vehicle is not performing container handling tasks, eliminating operational downtime and ensuring the vehicle is always ready for service
2Adaptability or versatility
If a power supply is installed in the container handling vehicle, then the vehicle gains mobility and functionality, but the vehicle's stability is compromised
Solution Approach 1:
The power supply is positioned in the upper part of the vehicle body, utilizing vertical space rather than horizontal space. This dimensional arrangement maintains the vehicle's lateral stability while providing the necessary power for autonomous operation
3Adaptability or versatility
If a power supply compartment is added to the vehicle, then the vehicle can be recharged, but the storage space for containers is reduced
Solution Approach 1:
The power supply compartment is located in the upper part of the vehicle body, utilizing vertical space above the storage compartment. This allows the vehicle to maintain full storage capacity in the lower section while accommodating the power supply system overhead
4Reliability
If a hook system is used to connect the power supply, then the power supply can be secured, but the system becomes complex and prone to failure
Solution Approach 1:
The complex hook system is replaced by a simplified direct connection mechanism where the power supply is securely positioned in the upper compartment with straightforward electrical contacts, eliminating the intermediate hook components and their associated failure points

AI summary
An automated storage and retrieval system includes a track system forming a grid pattern in the horizontal plane including a plurality of adjacent grid cells, each grid cell including a grid opening. A plurality of storage columns is located beneath the track system. Each storage column is located vertically below a grid opening and arranged to store a stack of storage containers. A container handling vehicle for lifting at least one storage container stacked in the stacks is configured to move laterally on the track system above the storage columns to access the storage containers via the grid openings. The container handling vehicle includes a lower part including at least one storage compartment for storing a storage container, an upper part arranged vertically above the lower part, a wheel assembly for guiding the container handling vehicle along the track system and a power supply compartment for accommodating a replaceable power supply; a replaceable power supply for accommodation in the power supply compartment, having a power supply charging connection. A charging station for charging of the replaceable power supply includes a charging connection configured to create an electrical connection with the power supply charging connection and a power supply support for releasably supporting the power supply during charging. The power supply compartment is arranged in the upper part of the container handling vehicle and is configured to receive the replaceable power supply via an opening.
