Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If an integrated structure is used for the extraction column, then structural strength and stability are improved, but ease of repair and adaptability deteriorate

Engineering Contradiction:
Improvestructural strengthVSAvoidease of repair
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The extraction column is divided into multiple detachable modules (first module, second module, third module) that can be separated and reconfigured. Each module contains functional components such as distributors, extractors, and collectors, allowing the column to be disassembled for repair or maintenance without compromising overall structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If an integrated structure is used for the extraction column, then structural stability is improved, but adaptability deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The column is segmented into standardized modules with consistent connection interfaces (flanges, gaskets, bolts) that maintain structural stability when assembled. The modular design enables adaptability by allowing modules to be added, removed, or reconfigured based on process requirements, while maintaining stable connections through standardized joining mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extraction column transitions from a fixed integrated structure to a dynamic modular configuration. Modules can be dynamically assembled or disassembled to adapt to different operational requirements, process conditions, or maintenance needs, while maintaining structural stability through standardized connection designs.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a modular structure is used for the extraction column, then ease of manufacture and adaptability are improved, but device complexity increases

Engineering Contradiction:
Improveease of manufactureVSAvoiddevice complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The extraction column is segmented into standardized modules that can be manufactured independently using the same design and fabrication processes. This standardization simplifies manufacturing by allowing repeated production of identical modules, reducing tooling costs, and enabling parallel manufacturing, while the modular assembly manages complexity through systematic design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular modules are designed with universal characteristics - identical connection interfaces, standardized dimensions, and interchangeable components (distributors, extractors, collectors). This universality allows any module to be used in multiple positions and configurations, reducing the variety of unique parts needed and simplifying the overall device complexity through standardization.

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