Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sludge fluidization or excavation methods are used, then sludge can be removed from storage tanks, but the process becomes time-consuming, costly, and hazardous to workers

Engineering Contradiction:
Improvesludge removal effectivenessVSAvoidtank cleaning duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces mechanical excavation and fluidization systems with a chemical dissolution system. A sludge dissolving composition is applied to the sludge layer, where it chemically breaks down the sludge into removable components, eliminating the need for mechanical pumping, fluidization, or manual excavation operations

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sludge dissolving composition acts as an intermediary substance between the sludge and removal equipment. It mediates the transformation of solid/semi-solid sludge into a form that can be easily pumped or removed, serving as a chemical bridge that facilitates the removal process without direct mechanical interaction

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If conventional sludge fluidization or excavation methods are used, then sludge can be removed from storage tanks, but the cost of the process increases significantly

Engineering Contradiction:
Improvesludge removal effectivenessVSAvoidprocess cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive mechanical excavation equipment, fluidization systems, and specialized pumping equipment with a simpler chemical treatment process. The sludge dissolving composition system requires minimal equipment infrastructure, significantly reducing capital and operational costs

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sludge dissolving composition is applied as a consumable chemical agent that performs its function and is then removed with the dissolved sludge. This disposable chemical approach eliminates the need for expensive, reusable mechanical equipment and complex infrastructure

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If conventional sludge removal methods are used, then sludge can be removed from storage tanks, but worker safety is compromised due to health hazards

Engineering Contradiction:
Improvesludge removal effectivenessVSAvoidworker health hazards
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical systems that require worker entry into confined tank spaces with a chemical treatment process that can be applied and monitored from outside the tank, eliminating exposure to hazardous atmospheres, heavy lifting, and confined space risks

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sludge dissolving composition performs the removal function autonomously through chemical action. The composition is applied to the sludge, which then self-dissolves and can be pumped out automatically, reducing the need for manual labor and direct worker involvement in hazardous conditions

Inventive Principle:
Principle #25Self-service
