Solution Overview

Problem

The condensation of moisture in the internal parts of a volumetric air compressor leads to oil emulsification, which compromises lubrication and causes corrosion, especially in vehicles where temperature fluctuations cause moisture condensation and mixing with oil.

Innovation Solution

An external protective covering member with heat insulation is applied to the compressor, featuring a split design with detachable components for easy maintenance, and includes openings for wiring and pneumatic lines, preventing condensation and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the volumetric air compressor operates in low temperature environment or during vehicle operation, then cooling effect is achieved, but moisture condensation occurs in internal parts causing oil emulsification

Engineering Contradiction:

Improvecompressor internal temperatureVSAvoidmoisture condensation

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

An external protective covering member is introduced as an intermediary between the compressor and the environment. This covering includes insulation material that mediates thermal transfer, preventing excessive cooling that leads to condensation, while also providing a physical barrier against moisture and contaminants.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The external protective covering converts the harmful cooling effect into a beneficial thermal insulation effect. By insulating the compressor, the harmful over-cooling that causes condensation is transformed into maintained operating temperature, preventing moisture accumulation while still allowing controlled heat dissipation.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Temperature

If the compressor body is exposed to environment, then heat dissipation occurs, but contamination by sewage, dust and road dirt occurs

Engineering Contradiction:

Improveheat dissipationVSAvoidcontamination

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The external protective covering acts as a flexible shell that encloses the compressor body. This shell provides physical protection against contaminants like sewage, dust, and road dirt, while its design allows controlled thermal exchange to maintain heat dissipation functionality.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The protective covering is designed with openings and detachable sections that segment the enclosure. This allows specific areas to remain accessible for heat dissipation and maintenance while other areas provide contamination protection, balancing thermal management with environmental protection.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If the compressor components are enclosed for protection, then contamination is prevented, but maintenance and repair become difficult

Engineering Contradiction:

Improvecontamination preventionVSAvoidcomponent accessibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of repair

Solution Approach 1:

The external protective covering is designed with detachable and movable components rather than fixed rigid structure. This dynamic design allows the covering to be easily removed or opened for maintenance and repair operations, then reassembled to restore protection, making the system adaptable between protected operation and maintenance modes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The protective covering is divided into multiple detachable sections or panels. This segmentation allows specific portions to be removed for accessing particular components, enabling maintenance without removing the entire covering, thus maintaining protection while facilitating repair access.

Inventive Principle:

Principle #1Segmentation
