Rotating Cover Trimmer Razor for Precision Shaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trimmer razors are inefficient due to bulky cartridge materials that obstruct precise shaving and lead to unnecessary waste and increased costs, as trimmer blades are often discarded with main blades when they become dull.
Innovation Solution
A trimmer razor design featuring a handle, head with a base member, seat, and cover, where the cover is rotatable to securely hold double-edged razor blades, allowing for easy replacement and providing a planar shaving surface for precise hair removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trimmer razors are incorporated into disposable cartridge razors, then utility and precision for hard-to-reach areas is improved, but waste and cost increase due to disposal of entire cartridge when main blades become dull
Solution Approach 1:
The razor system is divided into separate replaceable components: the handle with integrated trimmer blade and the detachable cartridge with main blades. This segmentation allows the trimmer blade to remain in the handle while only the main blades are replaced in the cartridge, preventing waste of the trimmer blade when main blades become dull.
2Strength
If bulky cartridge materials are used in trimmer razors, then structural integrity is improved, but shaving precision is worsened due to obstruction of blade positioning
Solution Approach 1:
The trimmer blade is extracted from the bulky cartridge structure and integrated directly into the handle. This removal of the trimmer blade from the cartridge eliminates the obstruction caused by bulky cartridge materials, allowing precise positioning and visualization of the blade for hard-to-reach areas while maintaining structural integrity through the handle's design.
