Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack fixing systems for ships require significant installation constraints, leading to space losses and inefficiencies, particularly in unstable maritime environments with variable thermal conditions, as they typically necessitate single-layer installations to ensure stability.
Innovation Solution
A system comprising adjustable holds, wall hooks, fixing hooks, and lateral supports that allow battery packs to be stacked and securely fixed in a battery room, utilizing grooves and wedges to stabilize the packs along multiple axes, enabling efficient use of space and stability in harsh conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery packs are installed in a single layer to ensure stability, then reliability is improved, but space utilization deteriorates
Solution Approach 1:
The patent transitions from single-layer horizontal arrangement to multi-layer vertical stacking, utilizing the vertical dimension (Z-axis) to increase space utilization while maintaining stability through specialized fixing mechanisms including adjustable wedges and locking systems that address maritime instability
2Volume of moving object
If adjustable wedges are used to secure battery packs in multiple layers, then space utilization is improved, but device complexity increases
Solution Approach 1:
The adjustable wedges serve multiple functions: they provide horizontal positioning, enable vertical stacking, and work in conjunction with fixing hooks and wall hooks to create a comprehensive stabilization system. This multi-functionality reduces the need for separate specialized components for each fixing requirement
Solution Approach 2:
The wedges are designed to be adjustable rather than fixed, allowing them to adapt to different battery pack positions and configurations. This adjustability provides dynamic adaptation to various installation scenarios while maintaining secure fixation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for the efficient stacking and secure fixation of battery packs in multiple layers, optimizing space usage and maintaining stability across axes X, Y, and Z, even in unstable environments, while reducing the number of different elements required for fixation.
Implementation Method 1
each adjustable wedge being intended to be inserted into an orifice formed between two fixing grooves of two battery packs placed in the fixed position next to each other in the same layer, to lock the battery packs between the side walls along the Y axis by adjusting the adjustable wedge
Implementation Method 2
each fixing hook being intended to be mounted on the distal wall of a battery pack and to lock this battery pack in the fixed position along the X axis by cooperation with the wall hook corresponding to it
