Solution Overview

Problem

Nausea-associated symptoms disrupt daily activities and can be unpredictable, making it inconvenient to carry medications, which may also impair concentration or operation of machinery, and conventional treatments have limitations.

Innovation Solution

Therapeutic patches with a non-permeable sealing layer, a pressure-sensitive adhesive layer containing a heat-sensitive homeopathic formulation, and a releasable layer, applied to the navel cavity, which includes active ingredients like belladonna, magnesia phosphorica, and chamomilla to reduce nausea and menstrual cramping symptoms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional medications are carried for nausea treatment, then effective treatment is available, but convenience is reduced and ability to operate machinery is impaired

Engineering Contradiction:

Improveeffective treatment availabilityVSAvoidability to operate machinery

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces conventional oral medications with a transdermal patch system that delivers homeopathic formulations through the skin, eliminating the need to carry pills or ingest substances that impair cognitive function. The patch provides continuous therapeutic delivery without affecting the user's ability to operate machinery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses a pressure-sensitive adhesive layer as an intermediary carrier that bonds the homeopathic formulation to the skin through the navel cavity. This intermediary system enables controlled drug delivery without requiring the patient to actively manage medication, resolving the contradiction between reliable treatment and operational convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If conventional medications are used for nausea, then symptoms are treated, but concentration and safety are adversely affected

Engineering Contradiction:

Improvesymptom treatment effectivenessVSAvoidimpairment of concentration

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the delivery parameter from oral ingestion to transdermal absorption, utilizing the skin as an alternative route that bypasses the harmful side effects of conventional medications on concentration and cognitive function while maintaining effective symptom treatment.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs disposable therapeutic patches that are applied and removed after use, eliminating the need for ongoing medication management that causes cumulative side effects. Each patch provides effective treatment without the long-term concentration impairment associated with conventional medications.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If homeopathic formulation is incorporated into adhesive layer, then therapeutic effect is achieved, but processing temperature must be kept low

Engineering Contradiction:

Improvetherapeutic effectVSAvoidprocessing temperature

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The patent applies local quality control by processing only the adhesive layer at low temperatures specifically where the homeopathic formulation is incorporated, while other layers of the patch can be manufactured at standard temperatures. This localized approach maintains therapeutic integrity without compromising overall manufacturing efficiency.

Inventive Principle:

Principle #3Local quality

AI summary

Therapeutic patches are presented including: a non-permeable sealing layer; a pressure sensitive adhesive layer bonded along the non-permeable sealing layer, where the pressure sensitive adhesive layer includes a formulation of a pressure sensitive adhesive and a heat sensitive homeopathic formulation, where the pressure sensitive adhesive layer is processed at a temperature less than approximately 1000 F; and a releasable layer attached along the pressure sensitive adhesive layer. In some embodiments, the therapeutic patch detectably reduces nausea associated symptoms and menstrual cramping. In some embodiments, the pressure sensitive adhesive layer includes at least approximately 15% by weight of the heat sensitive homeopathic formulation. In some embodiments, the pressure sensitive adhesive layer includes at least approximately 5 to 20% by weight of the heat sensitive homeopathic formulation.
