Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the strainer is designed to have a large filtering area to reduce flow resistance, then the filtering performance is improved, but the size of the strainer increases, making it difficult to install in space-constrained fuel pump modules
Solution Approach 1:
The filter is configured in an H-shape arrangement with first and second filtering portions extending in the length direction and connected by a connecting portion extending in the width direction. This multi-dimensional layout allows the filter to achieve a large filtering area while maintaining a compact overall size that fits within the fuel pump module's installation space.
Solution Approach 2:
The H-shaped filter structure allows filtering portions to be arranged in a nested-like configuration where the first and second filtering portions are spaced apart and connected through the central connecting portion, effectively utilizing three-dimensional space to maximize filtering area within a limited volume.
2Area of moving object
If the filter is designed with an H-shaped configuration and bent portions to maximize filtering area, then the filtering performance is improved, but the structural complexity increases, making manufacturing and assembly more difficult
Solution Approach 1:
The filter is divided into distinct segments including a first filtering portion, a connecting portion, and a second filtering portion, which are arranged in an H-shape configuration. This segmentation allows each portion to be independently formed and then assembled together, simplifying the manufacturing process while achieving the desired complex H-shaped structure with maximized filtering area.
Solution Approach 2:
The H-shaped configuration utilizes three-dimensional space arrangement with filtering portions extending in the length direction and connected by a width-direction portion, creating an efficient spatial layout that maximizes filtering area without requiring excessive structural complexity in any single dimension.

AI summary
A strainer for a fuel pump according to the present invention includes: a communicating pipe including a flow path formed to communicate with a fuel inlet of the fuel pump; a filter including an internal space in which a fuel flows and coupled to the communicating pipe so that the internal space communicates with the communicating pipe; and a rib disposed in the filter and coupled to the communicating pipe, in which the filter includes a first filtering portion extending in a length direction with respect to the communicating pipe, a connecting portion extending in a width direction at an edge of the first filtering portion, and a second filtering portion extending in the length direction at the connecting portion and spaced apart from the first filtering portion in the width direction. Therefore, the strainer may have a relatively large filtering area and a small size.
