Solution Overview

Problem

Existing oil delivery systems for motor vehicles face challenges in achieving a compact design while maintaining reliability and ease of manufacturing, particularly in limited installation spaces.

Innovation Solution

The oil delivery module features a pump positioned between the heat exchanger and oil pan, with a compact assembly that includes a multi-part housing and integrated oil filter receptacle, optimizing space usage and reducing pressure loss for improved efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the oil delivery module is designed compactly to fit limited installation space, then the space requirement is reduced, but the manufacturing complexity increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidmanufacturing complexity
Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The housing is divided into multiple separate parts (housing base, housing cover, housing frame) that can be manufactured independently and then assembled. This segmentation allows each part to be optimized for manufacturing while achieving a compact overall structure when combined.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pump is integrated into the housing structure by positioning it between the housing base and housing cover, with the connecting wall forming part of the housing frame. This nesting approach allows multiple components to occupy overlapping spatial volumes, reducing the overall installation space while maintaining manufacturability of individual parts.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Volume of moving object

If the pump is positioned between the heat exchanger and oil pan for compact design, then the space requirement is reduced, but the pressure loss may increase

Engineering Contradiction:
Improvemodule footprintVSAvoidpressure loss
Core Design Contradiction:
Volume of moving objectVSLoss of energy

Solution Approach 1:

The pump inlet and outlet are arranged in a vertically stacked configuration rather than horizontally aligned. The pump inlet is positioned on the connecting wall facing the oil pan, while the outlet faces the heat exchanger, creating a vertical flow path that reduces horizontal space requirements while maintaining efficient fluid dynamics.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The connecting wall serves as an intermediary structure that integrates the pump into the housing frame. This connecting wall with integrated pump mounting and port formation allows the pump to be positioned optimally between the oil pan and heat exchanger, minimizing flow path length and pressure loss while achieving compact dimensions.

Inventive Principle:
Principle #24Intermediary (Mediator)
