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

VSEngineering Contradiction Analysis

1Reliability

If battery packs are installed in a single layer to ensure stability, then reliability is improved, but space utilization deteriorates

Engineering Contradiction:
ImprovestabilityVSAvoidspace utilization
Core Design Contradiction:
ReliabilityVSVolume of moving object

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvespace utilizationVSAvoidfixation elements
Core Design Contradiction:
Volume of moving objectVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #15Dynamics
