Solution Overview

Problem

Existing methods for removing hydrogen from nanostructure materials, such as carbon nanotubes, are inefficient and energy-intensive, particularly for large-scale applications like powering automobiles, as they require heating the entire tank to high temperatures, which is difficult and time-consuming.

Innovation Solution

A method and apparatus using a microwave field to selectively heat a portion of the carbon nanostructure matrix, allowing for rapid and efficient release of hydrogen, utilizing a microwave energy generation system and waveguide to generate a microwave field that heats the carbon nanostructure material, causing it to release hydrogen quickly and on demand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the entire nanostructure tank is heated to high temperatures to remove hydrogen, then hydrogen removal is achieved, but the process becomes energy-intensive and time-consuming

Engineering Contradiction:
Improvehydrogen removalVSAvoidenergy consumption
Core Design Contradiction:
Quantity of substanceVSUse of energy by stationary object

Solution Approach 1:

The patent divides the nanostructure tank into multiple zones, with only a portion (first zone) containing the nanostructure material that needs hydrogen removal. This segmentation allows selective heating of only the necessary region rather than the entire tank, reducing energy consumption while achieving the required hydrogen removal quantity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by creating a temperature gradient where only the first zone containing nanostructure material is heated to high temperature for hydrogen removal, while other zones remain at lower temperatures. This localized heating approach reduces overall energy consumption while maintaining effective hydrogen removal in the target region.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If the entire nanostructure tank is heated to high temperatures to remove hydrogen, then hydrogen removal is achieved, but the process becomes time-consuming

Engineering Contradiction:
Improvehydrogen removalVSAvoidprocess time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

By segmenting the tank into zones with nanostructure material concentrated in the first zone, the patent enables focused heating of only that region. This reduces the thermal mass that needs to be heated, thereby decreasing the time required to achieve effective hydrogen removal compared to heating the entire tank.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial action by heating only the portion of the tank containing nanostructure material rather than the entire tank. This selective heating achieves sufficient hydrogen removal in a shorter time by concentrating thermal energy where it is most needed, without the time penalty of heating unnecessary regions.

Inventive Principle:
Principle #16Partial or excessive action

3Use of energy by stationary object

If selective heating of a portion of the nanostructure matrix is used, then energy consumption is reduced and hydrogen release is rapid, but the system complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidsystem complexity
Core Design Contradiction:
Use of energy by stationary objectVSDevice complexity

Solution Approach 1:

The patent implements segmentation by dividing the tank into distinct zones, with the first zone containing nanostructure material and the second zone serving as a buffer or cooling region. This segmentation enables selective heating of only the first zone, reducing energy consumption while maintaining manageable system complexity through clear spatial organization.

Inventive Principle:
Principle #1Segmentation
