Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional formulation applicators are inefficient in applying and activating photo-activatable formulations, as they require separate devices for dispensing and activating the formulations, leading to improper application and activation.
Innovation Solution
An applicator device that integrates a photo-active formulation assembly for dispensing and a photo-dose assembly for activating photo-activatable formulations, using focused electromagnetic energy to activate the formulations immediately after dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate devices are used for dispensing and activating photo-activatable formulations, then device complexity is reduced, but application precision and activation effectiveness deteriorate
Solution Approach 1:
The patent combines the dispensing mechanism and photo-activation source into a single integrated applicator device. The formulation reservoir, applicator element, and electromagnetic energy source are merged into one unit, allowing simultaneous or sequential dispensing and activation of the photo-activatable formulation directly on the skin surface, thereby improving application precision while maintaining manageable device complexity through functional integration.
2Ease of operation
If separate devices are used for dispensing and activating photo-activatable formulations, then ease of operation is improved, but activation effectiveness deteriorates
Solution Approach 1:
By integrating the photo-activation source directly into the applicator device, the system ensures that activation occurs precisely where the formulation is applied. This eliminates the need for separate handling steps and ensures reliable activation effectiveness, while the device remains easy to operate through a unified structure that performs both dispensing and activation functions in one action.
3Ease of operation
If formulations are exposed to air and environmental factors, then usability is maintained, but formulation stability and usable life deteriorate
Solution Approach 1:
The patent extracts the photo-activatable formulation from direct exposure to environmental factors by containing it within a sealed reservoir system until the moment of application. The formulation is dispensed in a controlled manner and immediately activated, minimizing its exposure time to air and environmental factors, thereby maintaining formulation stability and extending usable life while preserving usability.
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 integrated applicator device ensures efficient and precise application and activation of photo-activatable formulations, reducing waste and exposure to environmental factors, while improving usability and effectiveness.
Implementation Method 1
When the photo-activatable formulations are exposed to electromagnetic energy at the activation wavelength, the electromagnetic energy activates the photo-activatable formulations, causing the change or action
