Filtration Module Mounting Interface Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting configurations for filtration modules, such as those used in fuel filters, often lead to premature failure and require costly replacements due to assembly constraints and uneven stress distribution, resulting in the need to replace the entire filtration module assembly before the bracket fails.
Innovation Solution
A mounting assembly with a reinforced mounting interface designed to distribute stress more evenly, featuring a protruding portion with reinforcing members and a retention component that secures the interface to a u-shaped bracket, ensuring the bracket fails before the module, thus reducing the need for expensive replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bracket is made stronger than the mounting member on the housing, then the mounting bracket durability is improved, but the overall assembly durability deteriorates because the housing mounting member becomes the weak link that fails first
Solution Approach 1:
The patent changes the material parameter of the mounting member from standard plastic to a high-stress-margin material such as composite material, metal, or heavily reinforced plastic. This parameter change ensures the mounting member has equal or greater strength than the bracket, preventing premature failure and making the bracket the sacrificial component that fails first, thereby protecting the expensive filtration module.
Solution Approach 2:
The patent specifically mentions using composite materials for the mounting member to achieve the required stress margin. Composite materials provide high strength-to-weight ratio and can be engineered to match or exceed the strength of metal brackets while maintaining the integration with the housing structure.
2Reliability
If the mounting member on the housing is made stronger to match the bracket strength, then the assembly durability is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The mounting member is merged with the housing as an integral structure rather than a separate component. This integration eliminates the need for separate manufacturing and assembly of the mounting member, reducing manufacturing complexity while achieving the required strength through material selection and structural design.
Solution Approach 2:
By selecting materials such as composite materials or metals that can be molded or formed directly into the housing structure, the patent achieves high strength mounting members without requiring complex multi-step manufacturing processes. The material parameter change enables simpler manufacturing while meeting durability requirements.
3Ease of manufacture
If the mounting member is made from standard materials, then the manufacturing cost is reduced, but the stress margin is insufficient leading to premature failure
Solution Approach 1:
The patent changes the material parameter from standard plastic to high-stress-margin materials such as composite materials, metals, or heavily reinforced plastics. This parameter change directly addresses the insufficient stress margin issue while maintaining cost-effectiveness by selecting materials that provide the required performance without excessive cost increase.

AI summary
A mounting assembly is described that has an interface designed to increase the stress margin of at least the module side of the assembly, for example in a liquid filtration module, and to increase ease of assembling its mounting components. The interface reduces the failure of the mounting assembly at least on the module side, so that if failure of the mounting assembly occurs, such an occurrence is less likely to be at the interface and on the module side, thereby reducing the need to replace more complex and expensive components that may be on the module side. Generally, the mounting assembly includes a mounting interface and a mounting bracket connectable to the mounting interface. A retention component is configured to maintain connection of the mounting interface to the mounting bracket.
