Shaving Razor Handle With Undercut Ring For Container Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of simple and intuitive methods for removably attaching a liquid container to a shaving razor handle in a secure and ergonomic manner, which is necessary for personal care systems that combine shaving razors with fluid dispensing capabilities.
Innovation Solution
A handle design featuring a partially enclosed ring with an undercut region and a tab with a slot, allowing for the secure and removable attachment of a container, such as a tottle or tube, by engaging the container's flange and aligning it with the handle's alignment members, facilitating easy attachment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple attachment method is used, then ease of operation is improved, but security of attachment deteriorates
Solution Approach 1:
The attachment system is divided into separate components: a partially enclosed ring structure with an undercut region that receives the container body, and a separate tab structure with a slot that receives the flange. This segmentation allows each component to perform its specific function while maintaining overall simplicity and security of attachment.
Solution Approach 2:
The flange is nested within the slot of the tab, and the container body is nested within the partially enclosed ring. This nested arrangement ensures secure attachment while allowing easy insertion and removal, resolving the contradiction between ease of operation and security of attachment.
2Reliability
If a secure attachment method is used, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The attachment structure is segmented into two main parts: the partially enclosed ring with undercut region and the tab with slot. This segmentation reduces overall complexity by assigning specific functions to each segment while maintaining secure attachment through their coordinated interaction.
Solution Approach 2:
The undercut region and slot are designed to automatically engage with the container body and flange respectively, providing self-aligning and self-securing functionality. This self-service mechanism reduces the need for additional complex fastening components while ensuring reliable attachment.
3Reliability
If the container is tightly enclosed, then security of attachment is improved, but ease of operation deteriorates
Solution Approach 1:
The flange nests within the tab's slot and the container body nests within the partially enclosed ring, creating a secure yet easily removable attachment. The nested structure allows for simple insertion and removal actions while maintaining reliable attachment during use.
Solution Approach 2:
The partially enclosed ring structure provides dynamic attachment characteristics: it maintains secure engagement during normal use but allows easy removal when needed. The undercut region provides mechanical retention while the open structure permits simple insertion and removal operations.

AI summary
A handle for a personal care system with a first end having a head configured to engage a shaving cartridge, a second end with a partially enclosed ring having a first arm with a first end facing a first end of a second arm to defines a gap having a width. The first and second arms define an undercut region below the gap. A lower surface extends between the partially enclosed ring and the head, wherein the lower surface and the partially enclosed ring are configured to receive a container.
