Hemispherical Dispenser Cap with Integrated Applicator and Scraper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing depilatory composition products fail to effectively collect residue from the skin during application and require complex or multi-part designs that complicate the process.
Innovation Solution
A cap with a hemispherical design featuring a planar product application surface and a rounded product removal edge made from resilient thermoplastic elastomer, integrated with the container for both application and residue collection, allowing efficient use and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-use sachet with integral applicator and scraper is used, then the device is simple in construction, but it does not properly collect residue from the skin and requires complex construction
Solution Approach 1:
The patent combines the cap, applicator, and scraper into a single integrated unit. The cap serves multiple functions: it closes the container, applies product via its flat front surface, and collects residue through its curved rear surface that receives the scraper. This merging of functions into one component achieves both construction simplicity and effective residue collection.
Solution Approach 2:
The cap is designed as a multi-functional component that performs container closure, product application, and residue collection in a single element. The flat front surface applies product while the curved rear surface collects residue, making the cap a universal tool for the entire depilatory process.
2Adaptability or versatility
If a multi-part design with separate scraper tool is used, then the device can be reused, but it requires separation of parts and does not properly collect residue
Solution Approach 1:
The scraper is integrated into the cap structure rather than being a separate removable tool. The curved rear surface of the cap forms a recess that receives and holds the scraper, creating a unified reusable device that eliminates the need for parts separation while maintaining effective residue collection.
3Device complexity
If a traditional cap design is used, then the container is simple, but it cannot function as both applicator and residue collector
Solution Approach 1:
The cap is transformed from a simple closure into a multi-functional device. The flat front surface enables product application, while the curved rear surface with integrated scraper enables residue collection. This maintains container simplicity while adding significant versatility.
