Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If phosphorus-containing wastes are intensely combusted to generate a large amount of smoke and dust instantaneously, then the combustion efficiency is improved, but the activated carbon and spraying system are difficult to completely adsorb them in a short time, causing offgas pollution

Engineering Contradiction:
Improvecombustion efficiencyVSAvoidoffgas pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces a preheating system that preheats air before it enters the combustion chamber. This preliminary action allows the combustion process to proceed more efficiently while controlling the rate of smoke and dust generation, enabling the adsorption system to handle the offgas effectively.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs activated carbon as an intermediary substance in an adsorption tower to capture smoke and dust particles from the combustion offgas. The activated carbon serves as a mediator between the harmful combustion products and the environment, allowing efficient adsorption of pollutants.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a combustion tower is used for treatment, then the combustion process can be carried out, but the equipment occupies a large area and requires matching discharge air and offgas treatment systems, causing high cost

Engineering Contradiction:
Improvecombustion treatment capabilityVSAvoidequipment structure and cost
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single integrated device: the combustion chamber, preheating system, and adsorption tower are merged into one compact unit. This eliminates the need for separate large-scale combustion towers and independent offgas treatment systems, reducing both equipment complexity and cost.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a nested structure where the preheating system and adsorption tower are integrated within or adjacent to the combustion chamber in a compact arrangement. This nesting approach minimizes the overall equipment footprint while maintaining all necessary treatment functions.

Inventive Principle:
Principle #7Nested doll (Nesting)
