Tool Marking Structure with Segmented Protective Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for forming tool marking structures fail to clearly distinguish tool size and provide anti-rust functions 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 and forming a second protective layer with different colors in non-marking areas, ensuring the first protective layer remains visible and provides rust protection even after the color layer is rubbed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a color layer is printed on the tool surface for marking, then the marking visibility is improved, but the anti-rust function is lost when the color layer is rubbed
Solution Approach 1:
The marking structure is segmented into multiple functional layers: a color layer for visibility and a protective layer for anti-rust function. The protective layer is divided into a first protective layer formed on the entire tool surface before coloring, and a second protective layer formed on non-marking areas after coloring. This segmentation allows each layer to perform its specific function independently.
Solution Approach 2:
The first protective layer is formed on the entire tool surface before the color layer is applied. This preliminary protective layer ensures that the base metal is protected from rust before any marking is done. Even if the color layer is rubbed off, the underlying first protective layer remains to prevent rust.
2Loss of information
If concave patterns are imprinted on the tool for marking, then the marking structure is formed, but the anti-rust function is compromised when the color layer is rubbed
Solution Approach 1:
The second protective layer is selectively formed only on non-marking areas after the color layer is applied. This creates different protective characteristics in different locations: marking areas have the first protective layer beneath the color layer, while non-marking areas have both the first and second protective layers. This local differentiation maintains anti-rust protection while preserving marking visibility.
3Reliability
If the same color plating layer is formed on both the tool and the marking area, then the anti-rust function is maintained, but the marking cannot be clearly distinguished
Solution Approach 1:
The first protective layer and second protective layer are formed with different colors. The first protective layer (formed before coloring) has one color, while the second protective layer (formed on non-marking areas after coloring) has a different color. This color differentiation creates visual contrast that makes markings clearly distinguishable while both layers provide anti-rust protection.
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 effectively maintains visibility and anti-rust properties by creating color contrast and ensuring the protective layer remains on the bottom surfaces, allowing clear identification and protection of the tool.
Implementation Method 1
a first-time surface processing step including forming a first protective layer on a tool
Implementation Method 2
a second-time surface processing step including forming a second protective layer on a non-marking area of the tool

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 and forming the first protective layer on a bottom surface of the second protective layer; wherein the color of the first protective layer is different from that of the second protective layer.
