Solution Overview
Problem
Existing methods for delivering pharmaceutical and medical treatments, such as transdermal patches and spray-on formulations, face challenges in ensuring accurate and consistent dosing, particularly in adhering to the skin for extended periods and requiring user dexterity.
Innovation Solution
A dispenser comprising a hoop with multiple apertures and tubes connected to a pump, allowing for spray application of treatments without direct contact, with optional programmable control for precise dosing and pressure, suitable for various body parts and treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If transdermal patches are used to deliver drug, then treatment can be applied to skin, but it is difficult to ensure the patch continues to adhere sufficiently for long enough time for treatment to be effective
Solution Approach 1:
The patent replaces the mechanical adhesion system of traditional patches with a spray delivery system that uses fluid dynamics and surface tension to deposit treatment solution directly onto the skin. The spray mechanism eliminates the need for patch adhesion by delivering treatment in a controlled aerosol form that penetrates the skin barrier without requiring mechanical bonding.
2Ease of operation
If spray-on formulations are used to deliver drug, then treatment can be applied without contact, but significant dexterity is required and doses are very inconsistent
Solution Approach 1:
The patent incorporates feedback mechanisms including sensors to detect skin contact and position, microprocessors to control spray timing and duration, and flow meters to regulate treatment delivery. The system continuously monitors and adjusts spray parameters based on real-time feedback to ensure consistent dosing while maintaining contact-free operation.
Solution Approach 2:
The patent replaces manual mechanical spray control with an automated pump system that uses controlled mechanical actuation to deliver precise spray doses. The pump mechanism, combined with electronic controls, eliminates the need for user dexterity while ensuring consistent dosing through programmable control of spray duration and intensity.
3Adaptability or versatility
If manual spray application is used, then treatment can be applied to body parts, but accuracy of delivery is poor due to variation in user distance and pressure
Solution Approach 1:
The patent uses sensors to detect the presence and position of body parts, providing feedback to the control system. This enables the pump to automatically adjust spray timing, duration, and intensity based on the detected body part, ensuring accurate delivery while maintaining versatility across different body areas.
Solution Approach 2:
The system performs self-regulation by automatically controlling spray parameters based on sensor input without requiring user intervention. The pump system self-adjusts delivery characteristics to match the detected body part geometry, eliminating variability caused by manual operation while maintaining adaptability to different body areas.
