Monolithic Rotatable Grinding Tool With Integral Wear-Resistant Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable grinding tools for pipe lining require complex manufacturing processes and high costs due to separate abrasion-resistant teeth, which are prone to wear and require additional materials, complicating the manufacturing and increasing costs.
Innovation Solution
A monolithic rotatable grinding tool with teeth integral to the disc-like body, formed through casting, additive manufacturing, or machining, providing increased surface hardness and efficient debris removal through strategically placed openings and inclined teeth, simplifying the construction and manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate abrasion-resistant teeth are attached to the disc-like body, then wear resistance is improved, but manufacturing complexity and costs increase
Solution Approach 1:
The patent merges the teeth and disc-like body into a single monolithic structure formed by casting or additive manufacturing. This eliminates the need for separate tooth components and their attachment processes, thereby reducing manufacturing complexity while maintaining wear resistance through the integrated design and surface hardening of the entire structure.
Solution Approach 2:
The patent employs composite material strategies by forming the monolithic tool from materials that provide both structural integrity and surface wear resistance. The use of cast or additively manufactured materials with appropriate surface properties allows the single-piece structure to achieve the wear resistance previously requiring separate abrasion-resistant tooth inserts.
2Reliability
If separate abrasion-resistant teeth are attached to the disc-like body, then wear resistance is improved, but manufacturing costs increase
Solution Approach 1:
The patent merges the teeth and disc-like body into a single monolithic structure formed by casting or additive manufacturing. This eliminates the need for separate tooth components and their attachment processes, thereby reducing manufacturing complexity while maintaining wear resistance through the integrated design and surface hardening of the entire structure.
Solution Approach 2:
The monolithic design allows for cost-effective production of the entire tool as a single replaceable unit. Rather than investing in complex assembly processes for attaching separate teeth, the tool can be manufactured more cheaply as an integrated component that can be replaced when worn, reducing overall manufacturing costs.
3Reliability
If separate teeth are provided as separate components, then wear resistance is improved, but manufacturing steps increase
Solution Approach 1:
The patent merges the teeth and disc-like body into a single monolithic structure formed by casting or additive manufacturing. This eliminates the need for separate tooth components and their attachment processes, thereby reducing manufacturing complexity while maintaining wear resistance through the integrated design and surface hardening of the entire structure.
