Hair Removal Applicator Baffle for Liquid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair removal devices require multiple products and steps, leading to inconvenience, mess, and extended shaving experiences, with issues like microbial growth and clogging in razors due to liquid exposure, and a lack of soothing and moisturization benefits.
Innovation Solution
A hair removal device with a handle and cartridge featuring a dispensing unit that includes a reservoir, pump, and applicator, allowing for the dispensing of liquids during shaving, providing skin benefits without additional products and minimizing microbial growth risks through an airless system and flexible, barrier-resistant reservoir.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hollowed out razor handle or aerosol can is used to convey shaving preparation, then liquid dispensing is achieved, but the innerworkings become complicated and costly to manufacture
Solution Approach 1:
The applicator is merged with the cartridge assembly, eliminating the need for separate liquid conveyance mechanisms within the handle. The reservoir is positioned to directly interface with the applicator, simplifying the overall system architecture while maintaining liquid dispensing functionality.
Solution Approach 2:
The liquid storage and dispensing system is extracted from the handle structure and integrated into the cartridge assembly. This removes the complicated innerworkings from the handle while preserving the liquid conveyance function through a simplified path from reservoir to applicator.
2Ease of operation
If the razor is designed to convey liquid to the skin surface, then shaving preparation is provided, but microbial growth and clogging occur due to liquid exposure to air
Solution Approach 1:
A flexible barrier membrane is positioned between the reservoir and applicator to prevent direct liquid exposure to air while allowing controlled dispensing. This barrier film isolates the liquid from environmental contamination, preventing microbial growth and clogging of internal passages.
Solution Approach 2:
The flexible barrier membrane acts as an intermediary between the liquid reservoir and the external environment. It mediates the liquid dispensing process while maintaining isolation, preventing harmful interactions between the liquid and air that would cause microbial growth.
3Ease of operation
If multiple shaving products and application steps are used, then skin preparation is achieved, but the shaving process becomes inconvenient and time-consuming
Solution Approach 1:
The shaving preparation delivery system is merged with the hair removal device, combining what were previously separate products and steps into a single integrated operation. The liquid is dispensed automatically during the shaving process, eliminating the need for separate application steps.
Solution Approach 2:
The hair removal device is given multi-functionality by incorporating liquid dispensing capability. The single device now performs both skin preparation and hair removal functions, replacing the need for multiple separate products and steps.
4Ease of operation
If a reservoir system is used to deliver liquid, then shaving aid is provided, but clogging of innerworkings occurs
Solution Approach 1:
The flexible barrier membrane creates a sealed interface between the reservoir and applicator, preventing liquid from escaping into passages where it could cause clogging. The membrane allows controlled liquid transfer while maintaining isolation, ensuring reliable operation without blockages.
Applied Scientific Principles
