Solution Overview
Problem
Existing hair removal waxing methods are antiquated, unsanitary, and inaccurate, requiring manual handling of melted wax, which can be unsafe and inefficient.
Innovation Solution
A waxing apparatus with a dispenser and tip having a gradually decreasing cross section, featuring a heating element that creates a temperature gradient to maintain wax rigidity in the compartment while melting it in the tip for precise dispensing, along with a motor-driven dispensing mechanism and interchangeable applicators for various skin surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual manipulation of wooden spatula into communal vat of melted wax is used, then waxing can be performed, but sanitation and safety are compromised
Solution Approach 1:
The patent employs disposable single-use wax cartridges that are pre-filled with wax and discarded after use. This eliminates the need for communal wax vats and manual spatula manipulation, thereby resolving sanitation and safety concerns while maintaining ease of operation.
Solution Approach 2:
The invention extracts the wax storage and heating function into a separate, self-contained cartridge unit that is inserted into the device. This separation removes the harmful communal vat from the system while preserving the essential waxing function.
2Ease of operation
If manual manipulation of melted wax is used, then wax can be applied, but accuracy and precision are compromised
Solution Approach 1:
The patent replaces manual mechanical manipulation with an automated heating element and controlled dispensing mechanism. The heating element melts wax precisely where needed, and the applicator delivers it accurately to the target area, eliminating the imprecision of manual spatula work.
Solution Approach 2:
The device performs the wax melting and application functions automatically once the cartridge is inserted. The heating element self-regulates to melt wax at the correct temperature, and the applicator automatically positions and applies the wax, reducing reliance on manual dexterity for precision.
3Productivity
If heating element is mounted over compartment and tip with gradually decreasing cross section, then wax can be melted for dispensing, but temperature control becomes critical
Solution Approach 1:
The heating element is designed with varying heat distribution zones corresponding to the gradually decreasing cross-section of the tip. The wider compartment receives less intense heating to prevent overheating, while the narrower tip receives concentrated heat for efficient melting and dispensing, thus managing temperature control across different locations.
Solution Approach 2:
The patent utilizes the geometric parameter change of the tip (gradually decreasing cross-section) to naturally manage temperature distribution. The narrowing geometry concentrates heat in the dispensing area while the wider base dissipates heat more effectively, allowing temperature control through shape rather than complex thermal regulation.
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
The apparatus ensures safe, efficient, and accurate hair removal by maintaining wax solidity for mechanical pushing and melting it for easy dispensing, allowing controlled application and varying applicator sizes for different skin areas.
Implementation Method 1
a heating element mounted over the compartment and over the tip and configured such that temperature inside the tip is higher than temperature inside the compartment
Implementation Method 2
The heating element can be configured to heat the wax inside the tip to a temperature of 50-65° and to heat the wax in the compartment to a temperature of 45-50°
Implementation Method 3
melting it for easy dispensing
