Battery Module Guide Rail Stopper for Safe Rack Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face safety issues due to battery modules potentially falling and being damaged during insertion or removal, leading to safety incidents.
Innovation Solution
An energy storage system design featuring a rack frame, tray, guide rail, and stopper mechanism that restricts battery module movement, using a guide rail with a rail hole and a stopper with a hook and elastically deformable stopper body to prevent excessive movement and ensure safe insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery module is allowed to move freely during insertion and removal, then the ease of operation is improved, but the reliability deteriorates due to potential falling and damage
Solution Approach 1:
A stopper mechanism acts as an intermediary between the battery module and the guide rail. The stopper includes a stopper body that can move along the guide rail and a blocking portion that protrudes to contact and restrict the battery module's movement in the separation direction, preventing it from falling while allowing controlled insertion and removal operations
2Reliability
If a stopper mechanism is added to restrict battery module movement, then the reliability is improved by preventing falls, but the device complexity increases
Solution Approach 1:
The stopper body is designed to be movable along the guide rail rather than fixed. It can move in the insertion direction to allow battery module insertion, and then block in the separation direction to prevent falling. This dynamic design provides safety while maintaining operational flexibility without requiring multiple separate components
Solution Approach 2:
The stopper mechanism serves multiple functions: it guides the battery module during insertion, restricts excessive movement in the separation direction to prevent falling, and can be reset for repeated operations. The guide rail itself also serves as both a guide and a track for the stopper body movement, reducing the need for additional separate components

AI summary
An energy storage system includes: a rack frame; a tray provided to the rack frame; a battery module on the tray and insertable in the rack frame while moving in a first direction; a guide rail arranged to face the battery module and configured to guide movement of the battery module; and a stopper between the battery module and the guide rail and configured to selectively restrict movement of the battery module in a second direction opposite the first direction.
