Solution Overview

Problem

Industrial and commercial vehicles face challenges in reducing overall dimensions and optimizing production processes due to the increasing need for additional fluid tanks, such as urea tanks, which require additional space and supports, increasing production time and costs.

Innovation Solution

The method involves using dovetail couplings between the main tank and additional tanks, allowing for stable and space-efficient integration without the need for extra supports, utilizing complementary trapeziform recesses and protuberances for vertical or horizontal couplings, enabling cantilevered mounting and reducing the number of required brackets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional tanks are fitted to the vehicle using conventional mounting methods, then the vehicle can fulfill multiple functions (comfort, environmental standards, fluid storage), but the overall dimensions of the vehicle increase and the number of additional supports required increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidvehicle overall dimensions
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The additional tank is nested onto the main tank using a dovetail coupling mechanism, where the second tank is positioned on top of and coupled to the first tank. This nesting arrangement allows multiple tanks to occupy overlapping vertical space rather than requiring separate horizontal space, thereby reducing the overall vehicle dimensions while maintaining the ability to store multiple fluids for various functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The main tank serves multiple functions: it acts as both a fluid storage container and a structural support element for mounting the additional tank. The dovetail coupling mechanism also serves dual purposes by providing both mechanical support and fluid-tight sealing. This multi-functionality reduces the need for separate dedicated support structures, thereby reducing overall vehicle dimensions.

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

2Adaptability or versatility

If additional tanks are fitted using conventional mounting methods, then the vehicle can transport multiple fluids, but the number of additional supports increases and production costs increase

Engineering Contradiction:
Improvefluid storage capacityVSAvoidnumber of supports
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The main tank is designed to serve as both a fluid storage container and a structural support element. The dovetail coupling mechanism integrated into the main tank provides both mechanical support and fluid-tight sealing functions, eliminating the need for separate support brackets and mounting hardware. This reduces the number of parts and simplifies the overall structure while maintaining the ability to transport multiple fluids.

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

Solution Approach 2:

The support structure and the main tank are merged into a single integrated component. The dovetail coupling is formed as part of the main tank's structure rather than being a separate attachment. This merging of functions reduces the number of additional supports needed and simplifies production, thereby reducing production costs while maintaining fluid storage capacity.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If additional tanks are fitted using conventional mounting methods, then the vehicle can meet environmental standards and comfort requirements, but the production time and costs increase

Engineering Contradiction:
Improvecompliance capabilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The dovetail coupling mechanism is pre-formed as an integral part of the main tank during its manufacturing process. This preliminary action eliminates the need for separate support structures and simplifies the assembly process, as the additional tank can be directly coupled to the pre-prepared dovetail interface. This reduces production time and costs while maintaining the vehicle's ability to meet environmental standards and comfort requirements through multiple fluid storage capabilities.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting structure and main tank are combined into a single integrated component manufactured in one process. This merging eliminates the need for separate support brackets and simplifies assembly operations, thereby improving production efficiency. The integrated design maintains full compliance capability by preserving the ability to store multiple fluids required for environmental standards and comfort functions.

Inventive Principle:
Principle #5Merging (Combining)
