Stacked Battery Pack Bracing for Stable Marine Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing battery packs on ships require installation in a single layer due to instability and thermal variations, leading to inefficient use of space and constraints on installation.
Innovation Solution
A fixing system that allows battery packs to be stacked by using crosspieces, fixing screws, simple side rails, threaded side rails, and threaded rules, which securely fasten the packs along multiple axes, enabling vertical and horizontal stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery packs are installed in a single layer with hooks and wedges, then stability is improved, but space utilization deteriorates
Solution Approach 1:
The patent transitions from single-layer horizontal arrangement to multi-layer vertical stacking by introducing crosspieces that extend perpendicular to the battery pack faces, enabling utilization of the vertical dimension while maintaining stability through multi-axis constraint
2Volume of moving object
If battery packs are stacked vertically, then space utilization is improved, but stability deteriorates due to shocks and thermal variations
Solution Approach 1:
The fixing system is segmented into multiple independent constraint elements: crosspieces for vertical positioning, side rails for lateral constraint, and threaded rules for horizontal positioning. This segmentation allows each element to address specific stability requirements while working together to secure stacked battery packs
Solution Approach 2:
The system uses adjustable threaded connections that allow modification of fixing parameters (position, tension, orientation) to adapt to thermal expansion and contraction, as well as shock loads, maintaining stability across varying operational conditions
3Volume of moving object
If crosspieces and threaded rules are used for stacking, then space utilization is improved, but device complexity increases
Solution Approach 1:
The crosspieces serve multiple functions: they provide vertical support, enable lateral constraint through side rails, and facilitate horizontal positioning via threaded rules. This multi-functionality reduces the need for separate components for each constraint direction, managing complexity while achieving stable vertical stacking

AI summary
The present invention relates to a system for fixing a plurality of battery packs (20). Each battery pack (20) defining two side walls, a proximal wall, a distal wall, a top wall, a bottom wall and a plurality of grooves. The system comprises a plurality of crosspieces each defining a bottom wall, a top wall and a stepped through hole extending between the bottom and top walls of this crosspiece along a hole axis, and a plurality of fixing screws adapted to be inserted into stepped through holes until they abut against internal stops and to be screwed into tapped holes formed opposite the stepped through holes, thereby locking the corresponding battery packs (20) along the X axis.
