Heated Spray Cloud for Uniform Sunless Tanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skin treatment spray processes using sunless tanning compounds are uncomfortable due to cold temperatures, leading to uneven tan results and increased beading, as the cold spray causes goose bumps and evaporative cooling, which affects the deposition and longevity of the tan.
Innovation Solution
A heated spray cloud is applied using a formulation with an emulsifying wax, such as phosphate-based ceteth phosphate, which retains heat and is delivered through a spray nozzle system with integrated heating elements, ensuring the spray is warmed to a comfortable temperature, reducing nozzle expansion cooling effects and enhancing atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cold spray is used for skin treatment, then the spray can be applied quickly and easily, but the customer experiences discomfort and uneven tan results due to goose bumps and beading
Solution Approach 1:
The patent changes the temperature parameter of the spray from cold to warm by incorporating a heating element that heats the spray cloud to approximately 95°F. This resolves the contradiction by maintaining ease of spray application while eliminating the harmful cold temperature effects that cause goose bumps and beading on the skin
Solution Approach 2:
The patent introduces a heating element as an intermediary component between the spray nozzle and the skin. This heating element warms the spray cloud before it contacts the skin, mediating the interaction between the cold spray and the skin to prevent adverse reactions while maintaining the simplicity of spray application
2Object-affected harmful factors
If the spray is heated to a comfortable temperature, then customer comfort and tan uniformity improve, but the device complexity increases due to integrated heating elements
Solution Approach 1:
The patent merges the heating function with the existing spray device by integrating a heating element into the spray cloud generation system. This combination approach improves skin comfort and tan uniformity while avoiding the need for a completely separate heating system, thereby limiting the increase in device complexity
3Manufacturing precision
If heating is applied to the spray cloud, then deposition efficiency and tan longevity improve, but energy consumption increases
Solution Approach 1:
The patent optimizes the heating parameter by maintaining the spray cloud at a moderate temperature of approximately 95°F rather than high temperatures. This parameter optimization improves deposition efficiency and tan longevity while minimizing energy consumption, as the heating requirement is limited to a moderate temperature increase
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 solution provides a more comfortable and uniform tanning experience, resulting in a deeper, longer-lasting tan with reduced stickiness and improved deposition efficiency, while minimizing chill bumps and evaporative cooling.
Implementation Method 1
The heating element may be positioned upstream of and close to the point of atomization, which provides warmer air and eliminates the disadvantages of a heavy, insulated hose
Implementation Method 2
The nozzle 104 may comprise any suitable finely atomizing spray nozzle assembly known to those skilled in the art
Implementation Method 3
A formulation of the cosmetic or conditioning liquid may allow a pleasantly warm spray to be received on the skin surface. This formulation may include an emulsifying wax

AI summary
Embodiments disclosed herein propose the controlled application of a heated spray cloud to a target surface. The spray cloud may be delivered in connection with applications of atomized (misted) sunless tanning sprays using a variety of spray systems. A formulation of the cosmetic or conditioning liquid may conduct and retain heat to allow a pleasantly warm spray to be received on the skin surface. The formula may come to temperature quickly and the heat may be retained even though a nozzle cooling effect inherently cools the spray as it leaves the nozzle.
