Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fossil-origin plastics are used in filtration systems, then manufacturing cost is reduced and production is simplified, but environmental harm increases and filtering efficiency decreases

Engineering Contradiction:
Improvemanufacturing costVSAvoidenvironmental harm
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from fossil-origin plastics to biomaterials (sponges, pumice stone, resins, aluminum, carbon), transforming the environmental characteristics while maintaining filtration functionality. This parameter substitution resolves the contradiction by eliminating environmental harm associated with plastic waste while preserving manufacturing feasibility through natural material processing.

Inventive Principle:

Solution Approach 2:

The invention employs composite filtering masses combining multiple biomaterials (sponges, pumice stone, resins, aluminum, carbon) in specific configurations. This composite approach achieves superior filtering efficiency and environmental sustainability while maintaining production feasibility through established material processing techniques for each component.

Inventive Principle:
Principle #40Composite materials

2Productivity

If conventional plastic filtration systems are used, then production facility is maintained, but filtering efficiency is lower and maintenance frequency increases

Engineering Contradiction:
Improvefiltering efficiencyVSAvoidmaintenance frequency
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent changes the material composition parameter to biomaterials with superior filtration properties, achieving enhanced filtering efficiency and reduced maintenance frequency. The natural porosity, surface area, and chemical stability of biomaterials like activated carbon and zeolite enable more effective pollutant removal compared to conventional plastics.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention designs filtering masses that can be easily replaced when depleted, utilizing naturally degradable biomaterials that do not persist in the environment. This approach accepts periodic replacement of filtering masses while eliminating the need for frequent maintenance of complex mechanical systems, actually reducing overall time loss.

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

3Object-generated harmful factors

If biomaterials are used in filtration systems, then environmental sustainability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveenvironmental sustainabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments the filtration system into multiple independent filtering masses, each containing specific biomaterials for particular filtration functions. This segmentation allows for simplified manufacturing of individual components that can be produced separately and assembled, reducing overall manufacturing complexity while maintaining environmental sustainability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention applies different biomaterials to specific locations within the filtration system based on their optimal filtration properties. For example, activated carbon for chemical filtration, sponges for physical filtration, and zeolite for ammonia removal. This localized material selection optimizes performance while allowing each component to be manufactured using standard processes for that material type.

Inventive Principle:
Principle #3Local quality
