Comb-Shaped Outer Blade with Bent Distal Ends for Electric Razors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional comb-shaped outer blades for electric razors effectively scoop up body hair but tend to cause significant damage to the skin.
Innovation Solution
A comb-shaped outer blade design with a bent distal end that alternates with open blade parts, reducing skin damage while maintaining hair scooping efficiency, featuring a curved base with open and bent blade parts that gently connect to minimize skin contact and enhance structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a comb-shaped outer blade is used to scoop up body hair, then the effect of scooping up body hair is improved, but skin damage increases significantly
Solution Approach 1:
The outer blade is designed with different local characteristics: the distal end is bent to reduce skin contact area and minimize skin damage, while the blade body maintains comb-shaped structure to ensure effective hair scooping. This local differentiation allows each part of the blade to optimize its function while reducing overall harm.
Solution Approach 2:
The distal end of the outer blade is bent into a curved shape rather than remaining straight. This curvature reduces the contact area with the skin surface, minimizing skin damage while preserving the comb-shaped structure's ability to scoop up body hair effectively.
2Object-affected harmful factors
If the distal end of the blade is bent to reduce skin contact, then skin damage is reduced, but the structure may become weaker
Solution Approach 1:
The outer blade is divided into distinct functional segments: the blade body maintains a rigid comb-shaped structure for strength and hair scooping, while the distal end is separated as a bent portion that contacts the skin. This segmentation allows the strong base structure to support the weakened distal end, maintaining overall structural integrity while reducing skin damage.
Solution Approach 2:
The blade exhibits local quality differentiation where the distal end has reduced contact area for skin protection, while the main body retains full structural strength. The bent configuration at the distal end is strategically designed to minimize skin interaction without compromising the overall blade strength provided by the robust comb-shaped body.
