Pubic-Region Razor Handle Contours for Precise Shaving Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving razors designed for facial hair removal are inadequate for the pubic region due to anatomical challenges, sensitivity, and hair type differences, lacking ergonomic design and control for effective hair removal without irritation.
Innovation Solution
A shaving razor system with a handle and cartridge designed for the pubic region, featuring ergonomic contours, recessed areas for improved grip and control, and a cartridge ejection button placement to prevent accidental activation during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional facial shaving razor is used for pubic region, then the razor structure is simple and easy to manufacture, but the ergonomic control and precision are insufficient leading to higher risk of nicks and cuts
Solution Approach 1:
The handle is designed with a contoured lower surface that conforms to the curvature of the pubic region, providing localized ergonomic support for precise control during shaving. The guard is positioned to specifically address the anatomical challenges of the pubic area, creating local quality improvements for this specific application.
Solution Approach 2:
The razor is divided into separable components including a removable cartridge and a handle with integrated guard and cap. This segmentation allows for specialized design of each component optimized for pubic shaving while maintaining overall system functionality.
2Productivity
If the guard is positioned close to the blade for effective hair removal, then hair removal efficiency is improved, but the risk of nicks and cuts increases
Solution Approach 1:
The guard serves as an intermediary element between the blade and the skin. It is positioned to block stray blade movements from contacting the skin while still allowing the blade to effectively cut hair. The guard acts as a protective mediator that maintains hair removal efficiency while preventing harmful skin contact.
Solution Approach 2:
The guard is positioned in advance to create a protective barrier before the blade can cause harmful contact. This preemptive positioning prevents nicks and cuts by blocking potential harmful blade movements while maintaining the blade's cutting function.
3Measurement precision
If the razor is designed for pubic region with ergonomic contours, then control and precision are improved, but the manufacturing complexity increases
Solution Approach 1:
The handle incorporates curved surfaces and contoured shapes that match the anatomy of the pubic region. These curved geometries provide improved ergonomics and spatial awareness for the user while using standard molding techniques to manage manufacturing complexity.

AI summary
A shaving razor system with a cartridge having at least one blade. A handle having a proximal end configured to attach to the cartridge. A distal end of the handle having a lower contacting surface. The cartridge and the lower contacting surface define a plane with areas of contact to the plane includes the cartridge and the lower contacting surface. A first lower surface is spaced apart from the plane by about 14 mm to about 16 mm at about 82 mm to about 86 mm from the distal end. A second lower surface is spaced apart from the plane by about 14 mm to about 18 mm at about 66 mm to about 70 from the distal end. A third lower surface is spaced apart from the plane by about 6 about mm to about 10 mm at about 27 mm to about 31 from the distal end.
