Battery Pack Fixing System Using Stud-Piton Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing battery packs on ships require multiple installation constraints, leading to significant space losses and inefficiencies, especially in unstable environments with variable thermal conditions and shocks.
Innovation Solution
A system using pitons with threaded lower and tapped upper parts, beveled washers, and wall supports to securely stack battery packs, allowing for vertical and horizontal stabilization without the need for extensive space, using grooves and orifices to align and lock the packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery packs are fixed using hooks on the bottom and wedges/cleats for horizontal blocking, then the battery packs are secured in place, but significant space is lost and installation constraints increase
Solution Approach 1:
The invention transitions from two-dimensional fixed installation (single layer with hooks and wedges) to three-dimensional stacked installation by adding vertical stacking capability through the stud-piton connection system, enabling battery packs to be arranged in multiple layers along the vertical axis
Solution Approach 2:
The stud-piton assembly serves multiple functions: the piton provides vertical support from the floor, the stud connects adjacent packs horizontally, and the washer locks the assembly, creating a multi-functional fixing mechanism that replaces multiple separate components (hooks, wedges, cleats)
2Reliability
If multiple fixing elements (hooks, wedges, corners, cleats) are used to secure battery packs, then the packs are stable in unstable environments, but the device complexity and number of required elements increase
Solution Approach 1:
The invention merges multiple fixing functions into a single integrated stud-piton-washer assembly that simultaneously provides vertical support, horizontal connection, and locking capability, replacing the need for separate hooks, wedges, corners, and cleats
Solution Approach 2:
The stud-piton-washer assembly serves multiple functions: the piton provides vertical support from the floor, the stud connects adjacent packs horizontally, and the washer locks the assembly, creating a multi-functional fixing mechanism that replaces multiple separate components

AI summary
The 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, an upper wall, a lower wall and a plurality of fixing grooves. The system comprises a plurality of lateral locking pieces intended to be inserted into a groove, a plurality of studs (57) each defining a threaded lower part, a tapped upper part and an intermediate part comprising a bevelled washer, each stud (57) being adapted to be inserted into an orifice formed between two facing grooves provided with lateral locking pieces of two battery packs (20) placed next to each other in the same layer and to block the battery packs between the side walls along the Y axis.
