Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing epilatory compositions take a long time to soften, which delays the application process, as they require up to 30 minutes for sufficient softening, affecting efficiency and user experience.
Innovation Solution
An epilatory composition comprising a hydrocarbon resin, mineral oil, and polyethylene in specific weight ratios, which improves hair removal efficacy and reduces heating time by altering the intermolecular forces and melting point, allowing for quicker application and efficient hair removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If existing epilatory compositions are used, then hair removal function is provided, but heating time is excessively long (up to 30 minutes)
Solution Approach 1:
The patent modifies the chemical composition parameters of the epilatory material by incorporating specific ratios of hydrocarbon resin (1.3:1 to 2.8:1 weight ratio with mineral oil) and polyethylene homopolymer (0.5-5 wt%). These parameter changes alter the melting point and thermal properties of the composition, enabling it to soften faster at lower temperatures, thereby reducing heating time from 30 minutes to a significantly shorter duration while maintaining effective hair removal capability.
2Productivity
If heating time is reduced, then application efficiency is improved, but composition stability may be compromised
Solution Approach 1:
The patent creates a composite material system combining three distinct components: hydrocarbon resin, mineral oil, and polyethylene homopolymer. Each component serves a specific function - the hydrocarbon resin provides adhesive properties, the mineral oil acts as a plasticizer and solvent, and the polyethylene homopolymer modifies thermal properties. This composite structure achieves both fast heating (improved productivity) and composition stability through synergistic interactions among the components, with the specific weight ratios ensuring optimal balance between softening speed and structural integrity.
