Solution Overview

Problem

Current transport solutions require double the number of tanks for diesel fuel and AdBlue, making them inconvenient and inefficient for on-site refueling of vehicles equipped with nitrogen oxide abatement systems.

Innovation Solution

A compound transport tank with a removable AdBlue container integrated into a larger diesel fuel container, allowing for single-unit transport and refueling of both fuels on-site, featuring a seat for the AdBlue container within the diesel fuel container and a hinged lid for protection and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate tanks are used for diesel fuel and AdBlue, then each fuel can be transported independently, but the number of tanks doubles making transport inconvenient and inefficient

Engineering Contradiction:

Improveconvenience of transportVSAvoidnumber of tanks

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The AdBlue container (3) is nested inside the diesel fuel container (2), with the AdBlue container placed in a seat (20) formed within the diesel fuel container. This nesting arrangement allows both fuels to be transported in a single integrated tank unit, eliminating the need for two separate tanks while maintaining independent storage compartments for each fuel type.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Productivity

If a single tank is used for both diesel fuel and AdBlue, then transport efficiency improves, but the tank structure becomes more complex

Engineering Contradiction:

Improvetransport efficiencyVSAvoidtank structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The single tank is segmented into two distinct functional zones: the diesel fuel container (2) and the AdBlue container (3). The diesel fuel container includes a seat (20) that provides a dedicated compartment for the AdBlue container, creating clear separation between the two fuel types while maintaining a unified external structure for efficient transport.

Inventive Principle:

Principle #1Segmentation

3Stability of the object's composition

If the AdBlue container is permanently integrated into the diesel fuel container, then structural stability improves, but flexibility for separate refueling operations decreases

Engineering Contradiction:

Improvestructural stabilityVSAvoidrefueling flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The AdBlue container (3) is designed with removable characteristics, allowing it to be taken out from the seat (20) of the diesel fuel container (2) when refueling operations are needed. This dynamic design provides structural stability during transport while enabling flexible refueling operations, as the AdBlue container can be independently accessed and removed without disturbing the diesel fuel container.

AI summary

The fuel transport tank (1) comprises at least a first container (2) and at least a second container (3), the first container (2) being provided with at least a seat (20) in which the second container (3) is inserted in a removable manner.
