Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an enclosed gas collection area is used, then gas can be collected, but scum discharge becomes difficult and requires frequent manual intervention

Engineering Contradiction:
Improvegas collection reliabilityVSAvoidscum discharge operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention extracts the scum discharge function from the enclosed gas collection area by providing a separate scum discharge device that communicates with the gas collection area. This allows scum to be discharged independently without affecting gas collection, resolving the contradiction between reliable gas collection and easy scum discharge operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The scum discharge device acts as an intermediary between the gas collection area and the external environment. It provides a dedicated pathway for scum removal while maintaining the enclosed nature of the gas collection area, thus preserving gas collection reliability while improving operational ease

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If openings are provided for liquid flow, then liquid can pass through, but overall structural intensity is reduced

Engineering Contradiction:
Improveliquid flow throughputVSAvoidpanel structural intensity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The panel is designed with a porous structure containing numerous small openings that allow liquid to pass through. The porous design maintains overall structural intensity while providing sufficient flow pathways, resolving the contradiction between liquid flow productivity and structural strength

Inventive Principle:
Principle #31Porous materials

3Reliability

If a conventional slanting plate is used for solid-liquid separation, then separation occurs, but tank volume utilization is suboptimal

Engineering Contradiction:
Improvesolid-liquid separation effectivenessVSAvoidtank volume utilization
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The invention transitions from a conventional two-dimensional slanting plate to a three-dimensional modular panel structure with multiple layers and internal channels. This dimensional change enables effective solid-liquid separation while maximizing tank volume utilization through vertical space exploitation and compact modular design

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
