Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Titanium alloy products do not exhibit a blue color with excellent decorativeness.
Innovation Solution
A titanium member with a titanium content of 99% or more, featuring a first region with convex structural bodies arranged in a specific pattern on its surface, where the convex portions have a height of several ten nanometers and are spaced several hundred nanometers apart, creating a blue color through diffraction grating principles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional titanium alloy products are used, then the manufacturing process is simple, but the blue color with excellent decorativeness cannot be exhibited
Solution Approach 1:
The invention applies local quality by creating a specific surface structure only in the first region of the titanium member, where convex structural bodies with precise dimensional characteristics (height of several ten nanometers, interval of several hundred nanometers) are formed. This localized structural modification enables the blue color effect without requiring the entire titanium member to have complex structure, thus resolving the contradiction between achieving excellent decorativeness and maintaining manufacturing simplicity.
Solution Approach 2:
The invention utilizes parameter changes by precisely controlling the dimensional parameters of the convex structural bodies (height: several ten nanometers, interval: several hundred nanometers) to achieve the blue color effect. By adjusting these physical parameters within specific ranges, the patent achieves excellent decorativeness while maintaining a relatively simple manufacturing process, thereby resolving the technical contradiction.
2Shape
If the surface structure is modified to achieve blue color, then decorativeness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The invention applies parameter changes by defining specific dimensional ranges for the convex structural bodies (height: several ten nanometers, interval: several hundred nanometers) that enable the blue color effect. By establishing these parameter ranges, the patent achieves excellent decorativeness while providing clear manufacturing guidelines that balance precision requirements with manufacturability.
Solution Approach 2:
The invention applies partial action by requiring only that the convex structural bodies have dimensions within the specified ranges rather than demanding absolute precision. This approach achieves the blue color effect with acceptable manufacturing precision levels, avoiding the need for excessively high precision requirements while still obtaining the desired decorative appearance.

AI summary
A titanium member includes a first region where a plurality of first convex structural bodies extending in a first direction are arranged on the surface of the titanium member in a second direction orthogonal to the first direction, the first convex structural body has first convex portions arranged on an upper surface of the first convex structural body at an interval of several hundred nanometers along the first direction, and a height of the first convex portion is several ten nanometers. It is preferable that the first convex structural bodies adjacent in the second direction are arranged at an interval wider than the interval at which the first convex portions are arranged, and in the first convex structural bodies, a height including the first convex portion is higher than the height of the first convex portion.
