Tool Marking Structure with Protective Plating for Rust Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool marking structures fail to clearly distinguish tool size and provide anti-rust functionality as the color layer is rubbed, leading to visibility issues and rust problems.
Innovation Solution
A method involving a first protective layer on the tool, followed by coloring a marking area with a color layer and forming the protective layer on the bottom surface, and a second protective layer on non-marking areas, using electroplating to create a thickness difference for visibility and rust prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a color layer is printed on the tool surface for marking, then the tool size can be identified, but the color layer rubs off after long use revealing the underlying plating layer and losing visibility
Solution Approach 1:
The patent applies preliminary action by forming the protective plating layer on the tool surface before printing the color layer. This ensures that even when the color layer rubs off, the protective plating layer remains intact and provides a consistent background color that maintains the visibility of the marking area throughout the tool's service life.
2Loss of information
If concave patterns are imprinted on the tool for marking, then the marking area can be distinguished, but the bottom surface of concave patterns rusts badly when the color layer is rubbed
Solution Approach 1:
The patent applies preliminary action by forming the protective plating layer on the entire tool surface, including the bottom surfaces of any concave patterns, before applying the color layer. This ensures that rust-proofing is established in advance on all surfaces, preventing rust damage even when the color layer wears away.
Solution Approach 2:
The protective plating layer serves as a beforehand cushioning layer that protects the underlying tool material from rust. By establishing this protective barrier before the color layer is applied, the patent ensures that rust protection is in place beforehand, cushioning against potential rust damage when the color layer rubs off.
3Loss of information
If the same color plating layer is formed on both the tool surface and the bottom surface of marking areas, then the marking is visible initially, but the marking cannot be clearly distinguished when the color layer is rubbed
Solution Approach 1:
The patent applies local quality by creating a distinction between the marking area and the non-marking area through selective color application. The bottom surface of the marking area maintains the original plating layer color, while the non-marking area receives a different color plating layer, creating a permanent visible contrast that maintains marking distinction even after the color layer rubs off.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures clear tool size identification and anti-rust protection even after the color layer is rubbed, utilizing the visible difference in protective layer thickness for identification and maintaining rust prevention.

AI summary
A method of forming a tool marking structure includes: a coloring step of coloring a predetermined position of the first protective layer so as to form a marking area with a color layer and forming the first protective layer on a bottom surface of the marking area, and a second-time surface processing step of forming a second protective layer on a non-marking area of the tool.
