Latest Patents

Chou’s listed patents address blade geometry, skin contact, and protective coatings.

- **Shaving system.** This invention describes a blade with a wedge-shaped cutting edge whose main facets form an included angle of 10 to 17 degrees, measured 40 micrometers from the edge. The blade sits between leading and trailing skin-engaging surfaces. Its arrangement specifies a blade tangent angle below 20 degrees and positions the interior main facet at more than 150 degrees relative to a reference line extending from the cutting edge to the next forward skin-engaging point.

- **Razor technology.** This invention describes a razor blade with a wedge-shaped substrate edge coated with molybdenum on its tip and flanks. The molybdenum layer is preferably about 50 to 500 angstroms thick. A diamond or diamond-like layer covers the molybdenum, preferably at a thickness of about 200 to 1,500 angstroms, and defines a tip radius below about 1,000 angstroms.

Career Highlights

Chou’s listed inventions reflect work on improving razor blades through precise edge geometry and layered materials. The shaving-system design specifies how the blade is positioned in relation to skin-engaging surfaces, while the razor technology describes coatings intended for the blade’s wedge-shaped edge. The supplied information identifies The Gillette Company as his employer.
