Solution Overview
Problem
Current antiperspirant and deodorant products have long drying times on the skin, leading to user discomfort and environmental concerns related to packaging waste, with existing delivery methods offering limited control and efficiency.
Innovation Solution
A device combining airflow principles, such as the Venturi-Ejector and Coanda effect, to accelerate the drying of antiperspirant or deodorant substances on the skin, utilizing a portable and exchangeable vessel design that can be refilled, reducing packaging waste and enhancing user control over application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid or gel form antiperspirant/deodorant is applied to skin, then the product is easy to apply and comfortable, but the drying time is excessively long (5-10 minutes)
Solution Approach 1:
The patent applies pneumatic principles by using a stream of air (via hair dryer or similar device) to accelerate the evaporation and drying of the gel or liquid antiperspirant/deodorant on the skin. This airflow mechanism removes the harmful factor of long drying time while preserving the ease of application benefits of liquid/gel forms.
2Loss of time
If aerosol delivery method is used, then the drying time is quick and thin layer is delivered, but control over accuracy is reduced and environmental concerns arise from VOC propellants
Solution Approach 1:
The patent uses a stream of air as an intermediary mechanism to transfer the product from the applicator to the skin and control the drying process. This mediator approach provides both the quick drying benefit of aerosol and the controlled accuracy of liquid/gel application, while avoiding VOC environmental concerns.
3Ease of operation
If solid stick form with waxes is used, then the product feels drier initially and is easier to control, but it causes immediate staining of clothes and is difficult to remove
Solution Approach 1:
The patent changes the physical state parameter of the product by using liquid or gel forms instead of solid stick forms with waxes. This parameter change eliminates the staining harmful factor while maintaining ease of control through the air stream delivery mechanism, avoiding the need for wax-based solids.
4Object-generated harmful factors
If gel form is used, then immediate staining is avoided and drying is faster than liquid, but drying time remains high (5-10 minutes) and delivery mechanism is crude
Solution Approach 1:
The patent applies pneumatic principles using accelerated air flow to dramatically reduce the drying time of gel forms from 5-10 minutes to a much shorter duration. This resolves the contradiction by maintaining the non-staining benefit of gels while eliminating the excessive drying time through forced air circulation.
