Solution Overview

Problem

The integration of fuel cells and fuel tanks into electronic portable devices is challenging due to space constraints and the need for efficient fuel management, as these devices require a compact solution that can store fuel and provide structural support while maintaining operational efficiency.

Innovation Solution

A modular or unitary fuel tank is designed to be integrated within the frame of an electronic portable device, serving both as a fuel storage unit and structural component, with features like mechanical interlocking couplers, impact-resistant materials, and temperature control to manage fuel distribution and heat management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a fuel tank is added to an electronic portable device, then fuel storage capability is improved, but device volume increases

Engineering Contradiction:
Improvefuel storage capabilityVSAvoiddevice volume
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The fuel tank is merged with the device frame to form an integrated structure. The frame itself serves as the fuel tank, eliminating the need for a separate fuel storage component. This merging allows the device to have fuel storage capability while maintaining a compact form factor, as the frame performs dual functions of structural support and fuel containment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame is designed to perform multiple functions: providing structural support for the device and simultaneously serving as a fuel tank for storing and delivering fuel to the fuel cell. This multi-functionality resolves the contradiction by making the frame a universal component that addresses both structural and fuel storage requirements without increasing overall device volume.

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

2Volume of moving object

If a fuel tank is integrated into the device frame, then space utilization is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvespace utilizationVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The fuel tank and frame are combined into a single integrated component, which simplifies the manufacturing process by reducing the number of separate parts that need to be produced and assembled. The frame is manufactured with fuel storage cavities or channels directly incorporated into its structure, eliminating the need for separate fuel tank fabrication and assembly operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame is designed with segmented or modular sections that can be manufactured separately and then assembled, or with integrated fuel channels that are formed as distinct features during frame manufacturing. This segmentation allows for easier manufacturing of complex fuel storage structures within the frame while maintaining space efficiency.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the frame serves dual purposes as structural support and fuel tank, then device complexity is reduced, but reliability requirements increase

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The frame and fuel tank are merged into a single component, reducing device complexity by eliminating separate fuel storage and structural elements. However, this merging increases reliability requirements because the frame must simultaneously withstand mechanical loads and contain fuel without leakage or failure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame is constructed from composite materials or specially engineered materials that provide both structural strength and fuel compatibility. These materials resist fuel corrosion while maintaining mechanical integrity, thereby meeting the increased reliability requirements imposed by the dual-function design.

Inventive Principle:
Principle #40Composite materials
