Rack Housing Assembly Asymmetrical Shelf Bus Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face challenges in preventing short circuits during the assembly and operation of battery trays due to mislocated bus members, which can lead to malfunctions or fires.
Innovation Solution
A rack housing assembly with asymmetrical rack shelves and strategically positioned bus members that connect adjacent battery trays, including a current blocking device to prevent excess current flow, ensuring proper alignment and preventing short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bus members are used to connect battery trays, then electrical connectivity is improved, but risk of short circuits increases due to mislocation
Solution Approach 1:
The rack shelf acts as an intermediary component between the bus member and the battery tray. The bus member is positioned on the rack shelf rather than directly on the battery tray, and the rack shelf's asymmetric design ensures proper alignment. This intermediary structure prevents mislocation while maintaining electrical connectivity.
Solution Approach 2:
The rack shelf is designed with asymmetric dimensions where the first length (distance from first end to centerline) is greater than the second length (distance from second end to centerline). This asymmetric geometry ensures that the bus member can only be correctly positioned on the rack shelf, preventing mislocation that could cause short circuits while maintaining proper electrical connections.
2Ease of manufacture
If symmetrical rack shelves are used, then manufacturing simplicity is improved, but bus member positioning accuracy deteriorates
Solution Approach 1:
The rack shelf intentionally employs asymmetric dimensions with the first length greater than the second length. This asymmetry provides unique positioning features that guide the bus member to its correct location, ensuring positioning accuracy while remaining manufacturable using standard fabrication processes.
Solution Approach 2:
The rack shelf has different dimensional characteristics at different locations - the first length from the first end to centerline is deliberately made greater than the second length from the second end to centerline. This local variation in geometry provides the necessary positioning accuracy for the bus member without requiring complex manufacturing throughout the entire structure.

AI summary
A rack housing assembly, including a rack housing that defines a plurality of accommodation spaces opened at a front side to accommodate a plurality of battery trays; and a rack shelf that is in an inner space of the rack housing to house a battery tray and divides the plurality of accommodation spaces, the rack shelf being so dimensioned and positioned in the inner space of the rack housing as to block any mislocated bus member that serially connects each of the plurality of battery trays stacked in the rack housing to each other.
