Solution Overview

Problem

Conventional methods for preparing composite materials with metal porous bodies limit their application range by forming uniform polymer layers, restricting their versatility.

Innovation Solution

An asymmetrical composite material is developed with distinct polymer layers on both sides of a metal porous body, allowing for varied properties and expanded application areas by using different polymer components on each side.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional coating methods (deep coating or blade coating) are used to apply polymer to metal porous body, then the coating process is simple and efficient, but uniform polymer layers are formed on both sides which limits application range

Engineering Contradiction:
Improvecoating process simplicityVSAvoidapplication range
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies asymmetry by creating different polymer layer configurations on the two sides of the metal porous body. One side has a polymer layer while the other side has no polymer layer or has a different polymer layer configuration. This asymmetric structure allows the material to be optimized for specific applications on each side, thereby expanding the application range while maintaining manufacturing simplicity through selective coating methods.

Inventive Principle:
Principle #4Asymmetry

2Adaptability or versatility

If polymer layers with different components are applied on both sides of metal porous body, then application versatility is expanded, but manufacturing complexity increases

Engineering Contradiction:
Improveapplication areasVSAvoidmanufacturing process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the coating process into separate operations for each side of the metal porous body. Instead of applying a uniform coating to both sides simultaneously, the invention applies different polymer layers to different sides through sequential or selective coating processes. This segmentation allows for customized polymer compositions on each side while managing manufacturing complexity through systematic process design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by applying different polymer layer components to different regions (sides) of the metal porous body. Each side receives a polymer layer specifically tailored to its intended function, such as different polymer compositions, thicknesses, or properties. This localized customization expands application versatility while the patent addresses manufacturing complexity through targeted coating strategies.

Inventive Principle:
Principle #3Local quality
