Reusable Cosmetic Applicator with Segmented Reservoir
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic product packaging devices, such as mascara applicators, are not environmentally friendly as they require complete disposal after use and often result in product wastage due to rigid reservoirs that are difficult to empty, leading to applicator deterioration.
Innovation Solution
A cosmetic product application device featuring a protective outer band with an inner fastening mechanism that allows for removable and reusable reservoirs, reducing environmental impact and optimizing product restitution by preventing applicator deterioration and enabling easy replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid reservoir is used, then the structural integrity is maintained, but the product restitution is incomplete and applicator deterioration occurs
Solution Approach 1:
The device is divided into separate components: a reusable application device and a replaceable reservoir. This allows the reservoir to be discarded after use while retaining the applicator, resolving the contradiction between maintaining structural integrity and achieving complete product restitution.
Solution Approach 2:
The reservoir is designed as a single-use component that is discarded after the cosmetic product is depleted, while the application device is recovered and reused. This eliminates product wastage and applicator deterioration issues associated with rigid reservoirs.
2Reliability
If the entire device is discarded after use, then product contamination is prevented, but environmental impact increases
Solution Approach 1:
The device is segmented into a reusable application device and a disposable reservoir. Only the reservoir containing the cosmetic product is discarded, while the application device is retained for future use, reducing environmental impact while maintaining hygiene.
Solution Approach 2:
The reservoir is designed for single use and then discarded, while the application device is recovered and reused with new reservoirs. This approach prevents contamination by discarding the portion that contacts the product while preserving the non-contaminated applicator.
3Loss of substance
If the applicator is pressed to extract remaining product, then product restitution is improved, but applicator deterioration occurs
Solution Approach 1:
Instead of pressing the applicator to extract remaining product, the entire reservoir is discarded after use. This eliminates the need to apply force to the applicator, preventing bristle damage while ensuring complete product restitution by using the full reservoir contents.
4Strength
If a protective band is added to protect the applicator, then applicator protection is improved, but device complexity increases
Solution Approach 1:
The protective band is merged with the reservoir structure, forming an integrated unit. This provides applicator protection without adding separate components, as the band serves both protective and structural functions simultaneously.
