Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a significant disparity in treatment options for sexual dysfunction between men and women, with limited FDA-approved drugs and therapies available for women, and existing treatments often focus on symptom relief rather than addressing the underlying etiologies.

Innovation Solution

Injecting botulinum toxin (BoNT) directly into the clitoris to increase sexual arousal, sensation, and satisfaction by altering autonomic tone, increasing arterial blood flow, and potentially promoting neovascularization and neurogenesis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If botulinum toxin is injected into the clitoris to treat sexual dysfunction in women, then sexual arousal and satisfaction are improved, but the lack of FDA-approved treatments and established protocols for women creates treatment availability limitations

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtreatment availability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies botulinum toxin, originally developed for muscle relaxation and pain management, to a new universal application in female sexual dysfunction treatment. This multi-functional use of an existing drug addresses the lack of women-specific treatments by adapting a proven therapeutic agent for a new indication, thereby improving treatment availability while maintaining reliability through the drug's established safety profile

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the administration parameters of botulinum toxin by shifting from systemic or oral delivery to direct local injection into the clitoris. This parameter change enables targeted delivery to the specific anatomical site involved in sexual dysfunction, improving both treatment effectiveness and availability by creating a new treatment protocol for women

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If existing treatments like topical lubricants and anesthetics are used, then symptoms such as dyspareunia are relieved, but the underlying etiologies of sexual dysfunction are not addressed

Engineering Contradiction:

Improvesymptom reliefVSAvoidetiology treatment

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent extracts the core therapeutic mechanism of botulinum toxin—its ability to modulate neuromuscular function and promote tissue regeneration—and applies it directly to the clitoral tissue. This extraction of the active therapeutic principle from symptomatic treatments addresses the underlying etiology by targeting the neurovascular and structural causes of sexual dysfunction rather than merely masking symptoms

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses botulinum toxin as an intermediary agent that mediates between the nervous system and clitoral tissue. By injecting the toxin directly into the target tissue, it acts as a mediator that can modulate nerve signaling, promote blood flow, and stimulate tissue regeneration, thereby addressing root causes rather than just symptoms

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If surgical therapies are performed to improve sensation and self-image, then certain types of dyspareunia are treated, but these surgeries are relatively uncommon and lack curative potential for most etiologies

Engineering Contradiction:

Improvesurgical interventionVSAvoidcurative potential

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces mechanical surgical interventions with a pharmacological approach using botulinum toxin injection. This substitution eliminates the need for invasive surgery while maintaining treatment effectiveness, thereby improving curative potential and accessibility. The toxin's ability to modulate tissue function and promote regeneration provides a non-surgical alternative with comparable or superior therapeutic outcomes

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Injecting botulinum toxin directly into the clitoris can treat various sexual dysfunctions and improve sexual satisfaction in many women. Without wishing to be bound by this hypothesis, these effects of botulinum toxin may act by, inter alia, increasing arterial blood flow within the clitoris via vasodilation, neovascularization within the clitoris, neurogenesis within the clitoris, changing autonomic tone, and activating the mid-hypothalamus.
