Solution Overview

Problem

Existing screw compressor systems lack flexibility and compactness in design, making them less adaptable to various configurations and increasing production costs.

Innovation Solution

A modular design is implemented, combining essential components like the screw compressor block, oil separator tank, and air intake duct within a basic housing, along with a multifunctional block that integrates oil return, pressure control valve, and air outlet, allowing for flexible adaptation and reduced production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional non-modular design is used for screw compressor systems, then the system structure is simple, but the design flexibility and adaptability are reduced and production costs increase

Engineering Contradiction:
Improvedesign flexibilityVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The screw compressor system is divided into distinct modular components: a base housing containing the screw compressor unit and drive unit, and a separately attachable multifunctional block containing the oil separator, fine separator, and valve assembly. This segmentation enables flexible configuration and adaptation to different application requirements while maintaining structural simplicity through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multifunctional block integrates multiple functions including oil separation, fine separation, pressure regulation, and oil return within a single modular unit that can be attached to compatible base housings. This multi-functionality increases design flexibility and adaptability without proportionally increasing overall system complexity, as the same block can serve various configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Volume of moving object

If components are integrated into a single housing, then the system is more compact, but maintenance accessibility is reduced

Engineering Contradiction:
Improvesystem compactnessVSAvoidmaintenance accessibility
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The system separates components into a base housing and a multifunctional block that can be easily detached. This segmentation maintains compactness when assembled while enabling straightforward maintenance access by simply removing the multifunctional block to service the screw compressor unit or drive unit in the base housing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular architecture transforms the system from a fixed integrated structure to a dynamic configuration where the multifunctional block can be easily attached and detached. This dynamic design allows the system to transition between compact operational state and maintenance-accessible state, optimizing both compactness and ease of repair at different times.

Inventive Principle:
Principle #15Dynamics
