Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wear resistant components such as teeth, tooth adapters, and ripping tips lack sufficient wear resistance, necessitating improved designs to enhance durability in applications involving contact with earth and other abrasive materials.
Innovation Solution
A wear resistant component comprising a matrix portion made of metal with an embedded framework portion having a three-dimensional lattice structure formed by bar-shaped members, where the framework portion is harder than the matrix and shaped to follow the matrix's surface, suppressing wear progression and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a member of high hardness is disposed inside to improve wear resistance, then wear resistance is improved, but the structural integrity and reliability of the component deteriorates
Solution Approach 1:
The patent applies composite materials by combining a metal matrix portion with a framework portion made of higher hardness material. The framework portion is embedded in the matrix portion, creating a composite structure where the softer matrix provides structural integrity and toughness, while the harder framework provides wear resistance. This resolves the contradiction by allowing both materials to contribute their advantageous properties to the overall component performance.
Solution Approach 2:
The patent applies local quality by making the framework portion higher in hardness than the matrix portion, concentrating the hard material specifically where wear resistance is needed. The framework portion is shaped to follow the surface of the matrix portion, ensuring that the harder material is positioned at the wear-prone surfaces while the matrix portion maintains structural integrity throughout the component.
2Reliability
If a framework portion with high hardness is embedded in the matrix portion, then wear resistance is improved, but the complexity of manufacturing increases
Solution Approach 1:
The patent merges the matrix portion and framework portion into a single integrated component. The framework portion is embedded in the matrix portion during manufacturing, creating a unified structure rather than separate parts that need assembly. This merging simplifies manufacturing compared to assembling separate high-hardness inserts into a matrix, while still achieving the desired wear resistance.
3Reliability
If the framework portion is made with a three-dimensional lattice structure, then wear resistance and structural integrity are improved, but the device complexity increases
Solution Approach 1:
The patent applies porous materials through the three-dimensional lattice structure of the framework portion. The lattice structure creates a porous framework that is both lightweight and structurally sound, providing wear resistance through the distributed network of bar-shaped members while maintaining overall structural integrity. This porous structure achieves high wear resistance without requiring a solid, complex framework.

AI summary
A wear resistant component includes a matrix portion made of metal, and a framework portion that is embedded in the matrix portion and is higher in hardness than the matrix portion. The framework portion has a three-dimensional lattice structure formed with a plurality of bar-shaped members, and has a shape that follows a shape of at least a portion of a surface of the matrix portion.
