Integrated Razor Dispensing Unit for Airless Shaving Aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair removal methods, such as wet shaving, are inconvenient due to the need for multiple products and steps, often resulting in a messy process and extended time, with safety and performance issues related to microbial growth and clogging in razors.
Innovation Solution
A hair removal kit with a handle, removable cartridge, and integrated dispensing unit that includes a pump, applicator, and reservoir, allowing for the dispensing of a liquid shaving aid directly from the handle, reducing the need for separate products and minimizing exposure to air to prevent microbial growth and clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a reservoir is incorporated in the razor structure to convey shaving preparation, then the need for separate products is reduced, but microbial growth and clogging occur due to continued exposure of liquid to air
Solution Approach 1:
The reservoir is configured as an airless container that prevents air from contacting the shaving preparation liquid. The pump system draws liquid through sealed pathways, maintaining an inert environment that prevents microbial growth and oxidation throughout the product's shelf life and usage period.
Solution Approach 2:
A pump mechanism serves as an intermediary between the reservoir and the dispensing location. This intermediary component enables controlled liquid conveyance through sealed pathways, preventing direct exposure to air while maintaining reliable product delivery to the shaving head.
2Reliability
If multiple products and application steps are used for wet shaving, then adequate skin preparation is achieved, but the process becomes messy and time-consuming
Solution Approach 1:
The razor assembly integrates the shaving preparation dispensing system directly with the shaving head and handle. The pump, reservoir, and applicator are combined into a single unified device, allowing users to apply shaving aid and perform shaving in one continuous action without separate products or steps.
Solution Approach 2:
The razor assembly performs multiple functions: it stores shaving preparation liquid, dispenses it onto the skin, and executes the shaving action. This multi-functional design eliminates the need for separate shaving cream, applicator, and razor, streamlining the entire grooming routine into one tool.
3Extent of automation
If a pump system is integrated into the handle, then liquid dispensing is automated, but the device complexity increases
Solution Approach 1:
The pump system is designed to be manually activated by the user through simple interaction with the handle or button. The mechanism leverages user input to automatically convey liquid from the reservoir to the applicator, providing automated dispensing without requiring complex mechanical assemblies or external power sources.

AI summary
A hair removal kit having a handle, a cover removably engagable to the handle, and a cartridge removably engagable to the handle. The cartridge has at least one blade. A removable dispensing unit is disposed within the handle. The dispensing unit has a pump, an applicator in liquid communication with the pump, and a reservoir having a first position and a second position. The reservoir is in liquid communication with the pump in the second position, but not in liquid communication with the pump in the first position.
