Solution Overview

Problem

Lubrication circulation systems in machines face depletion of friction modifiers over time, leading to increased friction and reduced fuel economy, as existing solutions require frequent maintenance and are not efficiently integrated with standard oil filtration systems.

Innovation Solution

An additive fixture is integrated with the oil filter in the lubrication system, housing friction modifiers or other additives that are strategically released into the lubricant circulation, allowing for continuous modification of lubricant properties without significant hardware changes, and can be easily maintained or replaced during standard oil filter service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If friction modifiers are added to lubricant to reduce friction, then fuel economy is improved, but the additives become depleted over time requiring frequent maintenance

Engineering Contradiction:

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-loading the additive fixture with additive material sections before installation in the lubrication system. These pre-positioned additive sections are strategically placed to release friction modifiers at optimal intervals, eliminating the need for frequent maintenance while continuously improving fuel economy throughout the lubricant's service life

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements continuity of useful action through the additive fixture that continuously releases friction modifier additives into the lubricant circulation system. The multiple additive material sections ensure uninterrupted supply of friction-reducing chemicals, maintaining consistent fuel economy improvement without degradation over time

Inventive Principle:

Principle #20Continuity of useful action

2Reliability

If additive fixtures are integrated with oil filters, then additive distribution is improved, but device complexity increases

Engineering Contradiction:

AI summary

A lubrication system in a machine includes a sump to collect a bulk portion of lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to an area of the machine for lubrication. The lubrication system also includes an oil filter disposed along the lubrication line adapted to filer the lubricant flowing through the lubricant line. The lubrication further includes an additive fixture in fluid flow communication with the oil filter adapted to house at least one additive material section and distribute the additive material in a lubrication flow circulation.
