Razor Handle With Elastomer Cover and Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razor handles lack a secure and ergonomic design that prevents separation of the head from the body during handling and does not provide an effective grip, especially when exposed to water.
Innovation Solution
A handle for a razor cartridge comprising a body formed of a rigid material with a cover layer of thermoplastic elastomer, featuring through holes at the rear end and a clip member for secure assembly, along with a center rod for balance and flexibility, enhancing grip and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid body is used for the razor handle, then structural strength is improved, but grip security and ergonomics deteriorate
Solution Approach 1:
The handle combines a rigid body (providing structural strength) with a thermoplastic elastomer cover layer (providing enhanced grip security). This composite structure allows the rigid body to maintain structural integrity while the elastomer layer provides friction and comfort for secure handling, resolving the contradiction between strength and ease of operation.
2Ease of manufacture
If a smooth surface is used for the handle, then manufacturing simplicity is improved, but grip security deteriorates when exposed to water
Solution Approach 1:
The thermoplastic elastomer cover layer is applied specifically to the gripping portions of the handle where enhanced friction is needed. This localized application provides improved grip security in wet conditions without complicating the overall manufacturing process, as the cover layer can be molded or extruded onto the existing rigid body structure.
3Reliability
If the head assembly is firmly attached to the body, then reliability is improved, but ease of disassembly for cartridge replacement deteriorates
Solution Approach 1:
The handle design segments the attachment mechanism into a permanent rigid body-to-handle connection and a removable cartridge interface. The rigid body provides stable support while the cartridge interface is designed for easy release, allowing the head assembly to be firmly attached during use but easily disassembled for cartridge replacement, resolving the contradiction between reliability and ease of operation.
