Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional dust-containing gas treatment apparatuses are used, then they can treat gas containing dust of low concentration, but they cannot smoothly treat gas containing dust of relatively high concentration

Engineering Contradiction:
Improvedust removal efficiencyVSAvoidtreatment stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The treatment room is divided into multiple sections with catchers positioned at different heights and angles. Each catcher segment handles dust particles of different sizes and concentrations, allowing the system to process high-concentration dust without overload while maintaining stable operation through distributed processing zones

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The catchers are designed to rotate or move dynamically within the treatment room, adjusting their positions to optimize dust capture efficiency. This dynamic adjustment allows the system to adapt to varying dust concentrations and maintain both high productivity and reliable operation across different operating conditions

Inventive Principle:
Principle #15Dynamics

2Productivity

If more liquid is used to wash down dust, then dust removal efficiency improves, but liquid consumption increases

Engineering Contradiction:
Improvedust removal efficiencyVSAvoidliquid consumption
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

Liquid is sprayed preliminarily to pre-wet and agglomerate dust particles before they reach the catchers. This preliminary action enhances dust capture efficiency by making particles heavier and more easily collectable, thereby reducing the amount of liquid needed during the actual washing down phase while maintaining high dust removal efficiency

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The liquid that has washed down dust is collected in a storage portion and then sprayed again by the liquid spraying mechanism. This recovery and reuse cycle significantly reduces liquid consumption while maintaining continuous effective dust removal, as the same liquid serves multiple washing cycles

Inventive Principle:
Principle #34Discarding and recovering

3Loss of substance

If a complex liquid circulation system is implemented, then liquid usage efficiency improves, but device complexity increases

Engineering Contradiction:
Improveliquid usage efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The liquid storage portion and liquid spraying mechanism are integrated into a unified circulation system where liquid flows continuously from storage to spraying and back to storage. This merged design eliminates the need for separate pumping and control systems for each function, achieving efficient liquid reuse while keeping the overall system structure simple and manageable

Inventive Principle:
Principle #5Merging (Combining)
