Razor Handle Segmented Core and Overmolded Grip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor handles lack a combination of comfort, ease of manufacturing, and proprietary connection means for razor cartridges, which limits consumer preference for weight and slip-resistant surfaces.
Innovation Solution
A razor handle design comprising a core member with a weighted element, a cap member, and an overmolded member, where the connection member for attaching cartridges can be integral or separately attached, using materials like thermoplastic elastomers for improved grip and manufacturing methods like injection molding for cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a razor handle is made substantial with additional weight and slip-resistant surface, then consumer preference for comfort and grip is improved, but manufacturing complexity increases
Solution Approach 1:
The handle is divided into distinct functional segments: a core member providing structural support and weight, an overmolded member providing the slip-resistant exterior surface, and a connection member for the cartridge. This segmentation allows each component to be optimized and manufactured separately using appropriate processes, then assembled into the final product.
Solution Approach 2:
The handle employs composite construction by combining different materials with complementary properties. The core member uses materials for structural integrity and weight, while the overmolded member uses materials specifically for grip and slip-resistance. This composite approach achieves the desired comfort characteristics without requiring the entire handle to be manufactured from a single complex process.
2Adaptability or versatility
If a proprietary connection means is designed for razor cartridges, then product differentiation is improved, but device complexity increases
Solution Approach 1:
The connection member is designed to perform multiple functions: it provides the proprietary connection interface for cartridge attachment, serves as part of the handle structure, and can be integrated with or separate from the core member. This multi-functionality reduces the need for additional dedicated components, thereby limiting complexity increase despite the proprietary design requirements.
3Weight of moving object
If weighted element is added to core member, then handle weight and comfort are improved, but manufacturing steps increase
Solution Approach 1:
The weighted element is merged with the core member through integration, where the weighted element becomes an inherent part of the core member structure. This merging eliminates the need for separate assembly steps in many cases, as the weight is built into the core component during its formation process, thereby adding minimal complexity to the manufacturing process.

AI summary
A razor handle and method of manufacture, the razor handle having a connection member for connecting a razor blade cartridge to the handle, a core member, a cap member attached to the core member and an overmolded member surrounding the core member and bounded by the cap member, where the overmolded member and cap member form portions of the exterior surface of the handle.
