Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If only particle filtration is used in filter elements, then particle removal is achieved, but removal of dissolved harmful substances (heavy metals, radioactive contaminants) is not possible

Engineering Contradiction:

Improveremoval of harmful substancesVSAvoidcapability to handle different contaminants

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent combines particle filtration and adsorption of dissolved substances into a single integrated filter element. The filter medium and adsorption medium are positioned one above the other within the same element, allowing simultaneous removal of both particulate and dissolved contaminants from the fluid stream.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The filter element is designed to perform multiple functions: particle filtration through the filter medium and adsorption of dissolved harmful substances through the adsorption medium. This multi-functional design allows a single filter element to address diverse contaminant types, including particles, heavy metals, and radioactive contaminants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of stationary object

If a large number of filter elements are used to achieve large filter surfaces, then filtration capacity is improved, but maintenance complexity increases

Engineering Contradiction:

Improvefilter surface areaVSAvoidnumber of filter elements

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

Multiple filter elements are combined into a single cartridge assembly that functions as one replaceable unit. The cartridge contains several filter elements arranged in series, allowing the system to achieve large total filter surface area while maintaining simple maintenance procedures through single-unit replacement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Multiple filter elements are nested within a single cartridge housing. The elements are arranged concentrically or in series within the cartridge, allowing compact integration of large filter surface area into a single replaceable component that simplifies maintenance.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of repair

If filter elements are individually replaceable, then maintenance precision is improved, but maintenance time increases

Engineering Contradiction:

Improveselective element replacementVSAvoidmaintenance time

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

Multiple filter elements are combined into a single cartridge assembly that is replaced as one unit. This eliminates the time required to individually remove and replace multiple elements, while the cartridge design allows for selective replacement of entire assemblies based on contamination levels or operational requirements.

Inventive Principle:

Principle #5Merging (Combining)
