Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power feeding plug is located at the bottom of the charging shelf, then the charging system can be compact, but the connection between the power feeding plug and charging attachment becomes difficult and requires precise control
Solution Approach 1:
The patent inverts the conventional arrangement by placing the charging attachment at the bottom of the storage shelf and the power feeding plug at the top. This inversion allows the power feeding plug to automatically connect with the charging attachment during the stacking operation, eliminating the need for precise manual control and simplifying the connection process.
Solution Approach 2:
The system enables self-service connection where the power feeding plug automatically connects to the charging attachment through the movement of the stacker crane during normal stacking operations. The connection is made automatically without requiring separate manual intervention or precise positioning control, as the connection occurs naturally during the lifting and stacking process.
2Measurement precision
If precise control of the slide fork is required for connection, then connection accuracy can be improved, but the operation becomes more difficult and time-consuming
Solution Approach 1:
The charging attachment is pre-installed at the bottom of the storage shelf in a fixed position. This preliminary placement ensures that when the stacker crane lifts the cool box and places it on the shelf, the power feeding plug automatically aligns and connects with the charging attachment without requiring additional positioning adjustments or time-consuming manual intervention.
Solution Approach 2:
The connection process is automated through the self-service mechanism where the normal stacking operation itself performs the connection function. The stacker crane's movement during routine operations automatically brings the power feeding plug into contact with the charging attachment, eliminating the need for separate connection operations and reducing time loss.
3Ease of operation
If the cool box needs to be moved for connection, then connection can be achieved, but the operation becomes more complex and labor-intensive
Solution Approach 1:
The patent merges the charging connection function with the existing stacking operation. The same stacker crane that moves cool boxes for storage also performs the charging connection by simply placing the cool box on the storage shelf. This merging eliminates the need for separate connection operations and reduces operational complexity while maintaining ease of connection.
Solution Approach 2:
The system enables self-service where the cooling box itself participates in the connection process. When the stacker crane places the cool box on the storage shelf, the cool box's position automatically triggers the connection between its inlet socket and the power feeding plug. No additional manual operations are required, simplifying the overall process.

AI summary
The battery charging warehouse includes a pallet rack and a battery charger. The pallet rack has a plurality of storage locations in each of which a battery is stored. At least one of the storage locations is a charging storage location in which the battery is charged. The battery charger is mounted to an upper part of the charging storage location. The battery charger is movable up and down in the charging storage location and has a charge connector. When the battery charger is moved down in the charging storage location, the charge connector is received by a battery connector of the battery stored in the charging storage location thereby to automatically connect the charge connector to the battery connector.
