Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing depilatory wax applicators are difficult for laypersons to use safely and efficiently at home due to temperature control issues, wax adherence, and the need for additional disposable aids, leading to potential emissions and inefficiencies.
Innovation Solution
A temperature-controlled applicator with a heating unit and slide mechanism for applying molten depilatory wax directly to the skin without additional aids, ensuring safe and residue-free removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If wax is heated in open pots on stovetops or hotplates, then the wax melts and can be applied, but paraffin and/or wax vapors are released into the room and air we breathe
Solution Approach 1:
The patent introduces a heated applicator as an intermediary device between the heat source and the wax. The applicator is heated to a controlled temperature and then used to melt the wax locally during application, eliminating the need for open pot heating and preventing wax vapor release into the room.
Solution Approach 2:
The patent extracts the harmful heating process from the application process. Instead of heating wax in open containers, the heating function is separated and integrated into the applicator device, which controls melting locally at the application point, thereby removing the source of harmful vapors from the environment.
2Ease of operation
If wax is applied with a spatula, then the wax can be applied to the skin, but the application is time-consuming and requires a lot of experience to achieve the right layer thickness
Solution Approach 1:
The applicator is designed to automatically control the wax application process. The heated applicator melts and applies the wax in the correct amount automatically, eliminating the need for user skill in controlling layer thickness and removing the time-consuming manual spreading process.
Solution Approach 2:
The patent changes the physical state and temperature parameters of the wax during application. By controlling the temperature of the applicator and the resulting viscosity of the wax, the system automatically achieves the optimal application parameters without requiring user expertise or time for manual adjustment.
3Strength
If reinforcing strips are pressed into the wax strip, then the wax layer gains the strength required to be pulled off the skin, but additional disposable items are used up and have to be disposed of
Solution Approach 1:
The patent removes the reinforcing strip component from the system entirely. By controlling the wax composition and application temperature, the wax itself gains sufficient structural strength to be pulled off the skin without any additional reinforcing materials, eliminating the need for disposable strips.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the wax composition and application process. By adjusting the wax formula and application temperature, the wax achieves optimal strength characteristics that eliminate the need for external reinforcing elements, thereby reducing waste from disposable items.
