Razor Handle Segmented Shells and Elastomer Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razor handles lack a secure and ergonomic design that prevents separation from the razor cartridge during handling and does not provide optimal grip and balance.
Innovation Solution
A handle design comprising a body formed of two shells with a releasable coupling mechanism, a centerline rod for linear rigidity and balance, and a cover layer made of SEBS-based thermoplastic elastomer for enhanced grip, which is configured to securely attach to various razor cartridges and resist mishandling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional razor handle design is used, then the structure is simple, but the security against separation from the razor cartridge is insufficient
Solution Approach 1:
The handle body is divided into two separate shells (first shell and second shell) that are releasably coupled together, creating a segmented structure that enhances security against cartridge separation while maintaining manufacturing simplicity
Solution Approach 2:
The rod is disposed within the hollow interior of the body, and the cover layer at least partially surrounds the body, creating a nested configuration where components are housed within one another to improve structural integrity without significantly increasing external complexity
2Ease of operation
If a conventional razor handle design is used, then the manufacturing process is simple, but the grip and balance are not optimal
Solution Approach 1:
The cover layer made of SEBS-based thermoplastic elastomer provides enhanced grip specifically at the user contact areas, while the rod positioned within the hollow interior provides balance and structural support, applying specialized material properties where needed without complicating the overall manufacturing process
Solution Approach 2:
The handle combines different materials including SEBS-based thermoplastic elastomer for the cover layer and other materials for the body and rod, creating a composite structure that optimizes both grip and balance properties
3Reliability
If the body is formed as a single piece, then the manufacturing is simpler, but the ergonomic design and secure attachment are compromised
Solution Approach 1:
The body is segmented into two shells that are releasably coupled together, allowing for improved ergonomic design and secure attachment mechanisms while maintaining relatively simple manufacturing processes for each individual shell
