Plastic AdBlue Container Anchoring to Fuel Tank Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank systems for vehicles, particularly commercial vehicles, face challenges in securely and efficiently attaching plastic containers for chemically aggressive fluids like AdBlue, as existing methods require wide metal collars that increase material costs and risk leaks due to complex mounting and coating processes.
Innovation Solution
A plastic container design with end walls featuring depressions for fuel tank projections and internal indentations, allowing for secure anchoring with minimal additional components, using a combination of welding, gluing, and fastening means like screws or rivets, which can be retrofitted to existing tanks, ensuring stability and leak-proofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a wide metal collar is used to prevent softening during welding, then welding stability is improved, but material costs increase and handling becomes more difficult
Solution Approach 1:
The invention changes the wall thickness parameter of the container from thin to thick (at least 5mm) in the attachment area, eliminating the need for a wide metal collar while maintaining welding stability and preventing softening during the welding process
2Stability of the object's composition
If a wide collar is used for stable attachment, then attachment stability is improved, but the dimensions dictate the shape of plastic containers and increase material costs
Solution Approach 1:
The invention changes the wall thickness parameter and creates integral attachment areas directly on the container surface, eliminating the need for external collars that would constrain container shape design and increase material costs
3Ease of manufacture
If threaded bushes are melted into the container shell for attachment, then attachment is achieved, but leaks occur during vehicle operation due to ongoing load on the threaded bushes
Solution Approach 1:
The invention creates pre-formed attachment areas with integrated through-bores in the container wall before the attachment process, allowing fastening means to be inserted through both container and fuel tank for secure anchoring, eliminating the need to melt threaded bushes into the shell which creates leak risks
Solution Approach 2:
The invention uses a composite attachment system combining the container wall, attachment area with through-bores, and fastening means (screws, bolts, or rivets) to create a reliable leak-proof connection that can withstand ongoing operational loads
4Reliability
If a plastic container is attached using a console or rotolining coating, then chemical resistance is improved, but additional mounting brackets or complex coating processes are required
Solution Approach 1:
The invention merges the attachment function directly into the container structure by creating integral attachment areas with through-bores in the container wall, eliminating the need for separate mounting brackets or complex rotolining coating processes while maintaining chemical resistance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a space-saving, flexible, and cost-effective attachment of plastic containers to fuel tanks, providing long-term tightness and stability without the need for additional mounting brackets, while allowing for easy manufacturing and retrofitting, thus addressing the issues of material costs and leak risks.
Implementation Method 1
a side area (18) of the indentation (17) is connected to a bottom area (19) of the depression (16) welded or glued together in a manner that is impervious to operating materials
Implementation Method 2
a side area (18) of the indentation (17) is connected to a bottom area (19) of the depression (16) welded or glued together in a manner that is impervious to operating materials
Implementation Method 3
said areas (18, 19) which are welded or glued together and thus the container (3) are anchored to the respective corresponding projection (15) with the fastening means (21)
