Graduated Dose Dispenser and Applicator for Precise Transdermal Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication delivery methods, such as patches, pills, and injectables, cause skin irritation and anxiety, and lack discrete application in public settings, while oral administration results in dose loss.
Innovation Solution
A graduated dose dispenser and applicator with a cap, body, plunger, screw rod, pins, knob, channel, plunger lip, detent, alignment ribs, and round tip, made from pharmaceutical-grade plastics, allows for precise transdermal medication delivery with a tight seal and exact dosage per half-turn of the knob.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If oral medication is used, then medication delivery is simple, but dose loss occurs in the GI tract
Solution Approach 1:
The patent introduces a transdermal delivery system as an intermediary method between oral administration and direct tissue delivery. The medication is delivered through the skin via a graduated dose dispenser, bypassing the GI tract while maintaining ease of application through a simple knob-operated mechanism that provides precise dosing without requiring complex administration procedures
2Speed
If injectable medication is used, then rapid delivery is achieved, but anxiety from needles occurs
Solution Approach 1:
The patent extracts the needle component from the medication delivery system entirely. Instead of using injectable forms that require needles, the invention employs a graduated dose dispenser with a knob mechanism that delivers medication through a non-invasive application method, eliminating the source of anxiety while maintaining controlled and rapid medication delivery through precise dosing mechanisms
3Ease of operation
If patch medication is used, then discrete application is achieved, but skin irritation occurs
Solution Approach 1:
The patent changes the delivery parameters by transitioning from passive patch application to an active graduated dose dispenser system. The knob mechanism allows controlled, incremental dosing that can be adjusted to minimize skin contact and irritation, while maintaining discrete application capability. The system enables precise control over the amount of medication delivered to the skin, reducing irritation compared to traditional patches
4Ease of manufacture
If traditional medication containers are used, then manufacturing is simple, but exact dosage control is not achieved
Solution Approach 1:
The patent segments the dosage delivery mechanism into discrete, controllable components. The graduated dose dispenser divides the total medication into precise, measurable doses through a knob mechanism with detents that indicate exact dosage amounts. This segmentation allows for manufacturing using standard pharmaceutical container techniques while achieving precise dosage control through the mechanical division of the dosing mechanism
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
Enables accurate and discreet transdermal medication application directly to the nervous system, avoiding GI tract dose loss and skin irritation, with a secure seal and precise dosing mechanism.
Implementation Method 1
The plunger 15 is threaded onto the screw rod 20
Implementation Method 2
The cap 5 and body 10 are assembled with a 22-400 plastic bottle thread 55 for a complete and tight seal
Implementation Method 3
The channel 35 of the body 10 feature two detents 45, 46 which are located 180 degrees apart. One pin 25 is enlarged to catch the detent 45 when twisting knob 30
