Solution Overview

Problem

Conventional engines with oil coolers and filters require additional processing for drilled hole openings and complicate component mounting in manufacturing lines.

Innovation Solution

The engine design includes a base for component mounting that allows the oil cooler and filter to be pre-mounted, eliminating the need for additional processing by attaching the base to a seat, which facilitates easy assembly by simplifying the mounting process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the oil cooler and oil filter are mounted individually on the engine, then the cooling and purification functions are achieved, but the component mounting work becomes complicated

Engineering Contradiction:
Improvecooling and purification functionVSAvoidcomponent mounting complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the oil cooler and oil filter into a single integrated assembly that is mounted together on the engine. The base for component mounting supports both components in a unified structure, allowing them to be installed as one unit rather than separately, thus simplifying the mounting process while maintaining both cooling and purification functions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The oil cooler and oil filter are pre-assembled on a base for component mounting before being installed on the engine. This preliminary assembly allows the components to be prepared and positioned in advance, making the final mounting operation simpler and more efficient

Inventive Principle:
Principle #10Preliminary action

2Temperature

If the oil cooler is mounted on the engine with individual mounting, then the cooling function is achieved, but additional processing for drilled hole is required

Engineering Contradiction:
Improveoil cooling functionVSAvoidadditional processing requirement
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The integrated assembly combines the oil cooler, oil filter, and base for component mounting into a single unit. The base includes pre-formed mounting structures with attaching seats that eliminate the need for additional drilled holes during engine assembly, as the entire assembly can be mounted using existing engine mounting points

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base for component mounting serves as an intermediary structure that interfaces between the oil cooler assembly and the engine. It provides pre-formed attaching seats that align with engine mounting points, eliminating the need for additional processing on the engine block itself

Inventive Principle:
Principle #24Intermediary (Mediator)
