Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair removal methods using wax often irritate the skin and can lead to burns due to uncontrolled heating, with state-of-the-art devices failing to maintain the wax at an optimal temperature, resulting in low-quality hair removal and skin irritation.
Innovation Solution
A heating device with an electronically operated heat source and a depositing surface for flexible fabric strips, which can be heated to a setpoint temperature, ensuring the wax is viscous but still adheres to the strip, allowing controlled application and removal, reducing skin contact and irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wax is heated to high temperature for better hair removal, then hair removal quality improves, but skin irritation and burns increase
Solution Approach 1:
The patent applies parameter changes by precisely controlling the wax temperature to a specific range (40-50°C) rather than using high temperatures. This temperature optimization allows the wax to maintain adequate viscosity for good adhesion to hairs while being gentle enough on the skin, thus improving hair removal quality without causing skin irritation or burns.
Solution Approach 2:
The heating device incorporates temperature sensors and control systems that continuously monitor and adjust the wax temperature. This feedback mechanism ensures the wax remains within the optimal temperature range, preventing both underheating (poor adhesion) and overheating (skin irritation), thereby resolving the contradiction between effective hair removal and skin safety.
2Ease of operation
If wax is heated to melt for application, then wax becomes liquid and can be applied, but wax loses viscosity and adhesion to fabric strip
Solution Approach 1:
The patent utilizes parameter changes by identifying and maintaining the wax within a specific temperature window (40-50°C) where it achieves optimal fluidity for application while retaining sufficient viscosity to adhere to the fabric strip. This precise parameter control allows the wax to be neither too viscous (hard to apply) nor too liquid (poor adhesion).
Solution Approach 2:
The heating device preheats the wax to the optimal temperature range before the user needs to apply it. This preliminary action ensures the wax is in the ideal state for application - sufficiently liquid to spread easily on the fabric strip but still viscous enough to maintain strong adhesion, eliminating the need for the user to manually heat and control the wax.
3Power
If conventional heating devices are used, then wax can be heated, but temperature control is poor leading to overheating
Solution Approach 1:
The patent implements feedback control through temperature sensors that continuously monitor the wax temperature and automatically adjust the heating power accordingly. When the wax approaches the upper temperature limit (50°C), the system reduces or stops heating, preventing overheating. This feedback mechanism ensures reliable temperature control while maintaining adequate heating capability.
Solution Approach 2:
The patent replaces conventional mechanical or manual heating control with an electronically controlled heating system featuring automated temperature regulation. This substitution of control mechanisms provides precise and reliable temperature management, eliminating the temperature control issues associated with conventional heating devices while maintaining effective heating capability.

Function Achieved in This Case
The device efficiently heats the wax to an optimal temperature, minimizing skin irritation and improving hair removal quality by maintaining the wax in a viscous state for better adhesion and application, while also allowing for adjustable temperature settings for different skin areas.
Implementation Method 1
a heating device with an electronically operated heat source which can be supplied with electrical energy by an electrical energy supply unit
Implementation Method 2
The wax on the fabric strip is heated to the target temperature, whereby at the setpoint temperature the wax is still viscous, so that it still adheres to the fabric strip

AI summary
A heating device for heating wax includes an electronically operated first heat source that can be supplied with electrical energy by an electrical energy supply unit. In order to constructively simplify the processing, handling and use of wax for body hair removal, it may be provided that the heating device has a depositing surface on which at least one flexible fabric strip can be deposited directly or indirectly and which can be heated by means of the heat source, the fabric strip having a wax layer and the heating device being designed for this purpose, to heat the fabric strip with the wax layer up to a setpoint temperature, the setpoint temperature being adjustable by a user, and the heating device being configured to provide corresponding output signals in a time-controlled manner by means of output indicators as soon as the wax is in a viscous state.
