Hydrogen Tank Chassis Layout for Impact-Protected Handling Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling machines with fuel cell systems do not provide effective protection against shocks and fires, which are major causes of hydrogen tank explosions.
Innovation Solution
The hydrogen tank is housed within the chassis between two longitudinal side members, with the hydrogen-consuming equipment located in a separate compartment, and critical supply line portions are housed within the chassis to enhance protection against impacts and leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydrogen is stored in a tank on a handling machine, then hydrogen can be transported and processed, but the tank may move unintentionally during handling operations
Solution Approach 1:
The restraint system is divided into multiple independent restraint members (first restraint member, second restraint member, third restraint member) that can be independently positioned and adjusted. Each restraint member can be separately operated to secure the tank at different locations on the handling machine, allowing flexible constraint of tank movement without requiring a single complex restraint mechanism.
2Stability of the object's composition
If the tank is secured with restraint members, then tank movement is prevented, but the restraint members may interfere with each other during installation
Solution Approach 1:
The restraint members are designed with movable and adjustable characteristics, allowing them to be dynamically positioned during installation and operation. The restraint members can be moved to different positions and orientations to accommodate the tank's location and shape, enabling easy installation while maintaining effective restraint. This dynamic adjustability prevents interference between restraint members during installation.
3Stability of the object's composition
If multiple restraint members are used to secure the tank, then tank stability is improved, but the complexity of the restraint system increases
Solution Approach 1:
Each restraint member is designed with multi-functionality, capable of performing multiple restraint operations through different positions and orientations. The restraint members can be adjusted to restrain the tank at various locations and angles, providing comprehensive stabilization without requiring a large number of specialized components. This universal design reduces overall system complexity while maintaining effective tank restraint.
