Transparent Depilatory Article for Accurate Skin Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate-based depilatory compositions lack accurate positioning and risk skin irritation due to uncontrolled application, as users cannot visually assess the application process, leading to incomplete or excessive exposure.
Innovation Solution
A transparent and non-reflective depilatory article with a transparent substrate and composition, allowing users to see the skin and hair during application, along with indicia for guidance, enabling accurate placement and monitoring of the depilation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a substrate-based depilatory composition is used, then the need for an application implement is reduced, but accurate positioning of the depilatory article becomes difficult
Solution Approach 1:
The patent applies transparency as a visual indicator to enable users to see the skin and hair through the substrate, allowing accurate positioning and monitoring of the depilation process. The transparent substrate and composition allow visual feedback during application, resolving the positioning accuracy issue while maintaining ease of operation.
2Ease of operation
If the depilatory composition is disposed on a substrate, then handling problems of creams and lotions are addressed, but visual assessment of application and progress becomes impossible
Solution Approach 1:
The patent makes both the substrate and depilatory composition transparent, enabling users to visually assess the application process and monitor hair removal progress through the article. This maintains the handling advantages of substrate-based products while restoring visual feedback capability.
3Productivity
If the depilatory article is placed without visual guidance, then application speed is maintained, but skin irritation and ineffective depilation occur
Solution Approach 1:
The transparent design provides real-time visual feedback to users during application, allowing them to see where the composition is applied and monitor the depilation process. This enables accurate positioning and appropriate exposure time control, preventing both skin irritation from excessive application and ineffective depilation from insufficient coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves user accuracy in applying the depilatory article, reduces skin irritation, and enhances hair removal efficacy by allowing visual assessment of progress without relying on timing.
Implementation Method 1
A transparent and non-reflective depilatory article with a transparent substrate and composition, allowing users to see the skin and hair during application
Implementation Method 2
Such compositions may comprise thioglycolate salts to degrade keratin in the hair and thus weaken the hair strands
