Modular Compressed Gas Tank Mounting Structure

Solution Overview

Problem

Existing mounting methods for compressed gas storage tanks in vehicles are cumbersome, increasing weight and manufacturing costs, and fail to adequately protect high-pressure parts and pipes from external collisions or impacts.

Innovation Solution

A modular mounting structure using panel brackets and pipe frames with protective panels to connect and secure high-pressure storage tanks, incorporating gaskets and springs for expansion absorption, and extending pipe frames with protective panels to safeguard against impacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional mounting methods using belt-shaped brackets and frames are used, then the storage tanks can be mounted on the vehicle body, but the weight and manufacturing cost increase due to the complicated structure

Engineering Contradiction:

Improvemounting reliabilityVSAvoidsystem weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The mounting structure is divided into separate functional components: panel brackets for securing tanks to the vehicle body, and pipe frames for protecting high-pressure piping. This segmentation allows each component to be optimized independently, reducing overall complexity and weight while maintaining mounting reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The panel brackets serve multiple functions: they mount the storage tanks to the vehicle body and simultaneously provide structural support for the piping system. This multi-functionality eliminates the need for separate mounting and support structures, reducing weight and manufacturing cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If traditional mounting methods using belt-shaped brackets and frames are used, then the storage tanks can be mounted on the vehicle body, but the manufacturing cost increases due to the complicated structure

Engineering Contradiction:

Improvemounting reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The mounting structure is divided into separate functional components: panel brackets for securing tanks to the vehicle body, and pipe frames for protecting high-pressure piping. This segmentation allows each component to be optimized independently, reducing overall complexity and weight while maintaining mounting reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The design uses simpler, more easily manufactured components that can be produced at lower cost. The panel brackets and pipe frames are designed with straightforward geometries that reduce manufacturing complexity and material usage, lowering overall system cost.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If traditional mounting methods are used, then the storage tanks can be mounted, but high pressure parts and pipes are not adequately protected from external collision or impact

Engineering Contradiction:

Improvemounting efficiencyVSAvoidimpact resistance

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The mounting structure is divided into separate functional components: panel brackets for securing tanks to the vehicle body, and pipe frames for protecting high-pressure piping. This segmentation allows each component to be optimized independently, reducing overall complexity and weight while maintaining mounting reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pipe frames are designed to surround and protect high-pressure piping before any collision occurs. This protective enclosure provides beforehand cushioning against external impacts, preventing damage to the piping system while allowing efficient mounting of the storage tanks.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
