Blow-Molded Dry Sump Tank With Integrated Filter Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dry sump lubrication systems for internal combustion engines face challenges in space constraints and increased complexity and cost due to separate components, particularly with the need for additional space and components for oil filtration.
Innovation Solution
A tank with an integrated filter housing formed by blow molding, which includes a body with a first and second portion defining an inner chamber, where the filter housing is integrally formed with the first portion and disposed inside the chamber, reducing the need for additional space and components, and formed from suitable materials like polyamide or high-grade plastic.

Engineering Contradiction Analysis
1Area of stationary object
If lubricating oil is stored in a separate tank for dry sump lubrication system, then space constraints are resolved, but device complexity and cost increase due to additional components
Solution Approach 1:
The filter housing is integrally formed with the tank body through blow molding, merging two previously separate components (tank and filter housing) into a single integrated structure. This eliminates the need for separate filtration components and fixtures, thereby reducing device complexity and cost while maintaining the space benefits of external oil storage
Solution Approach 2:
The integrated tank structure serves multiple functions: it provides external oil storage space, houses the filtration system, and eliminates the need for separate mounting fixtures. The blow-molded integrated design combines storage and filtration functions in a single component, reducing the overall number of parts required in the dry sump lubrication system
2Reliability
If separate filtration components are used in dry sump system, then oil filtration is effective, but cost and manufacturing complexity increase
Solution Approach 1:
The filter housing is integrally formed with the tank body through blow molding, merging two previously separate components (tank and filter housing) into a single integrated structure. This eliminates the need for separate filtration components and fixtures, thereby reducing device complexity and cost while maintaining the space benefits of external oil storage
Solution Approach 2:
The invention changes the manufacturing parameter from assembling multiple separate components to using a single blow molding process. This parameter change in the manufacturing method reduces assembly steps, eliminates the need for separate fixtures, and lowers manufacturing cost while maintaining effective oil filtration through the integrated filter housing
