Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current treatments for chronic migraine using Onabotulinumtoxin A involve numerous injections and high doses of neurotoxin, leading to immune reactions and side effects such as muscle weakness and ptosis.

Innovation Solution

The use of Clostridial neurotoxins, including botulinum toxins, for treating headaches like migraine, employing a combination of intra-muscular injections and saturation of nerve-rich trigeminal administration sites, with specific injection protocols that avoid certain muscle regions to minimize side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If large doses of neurotoxin are administered via numerous injections, then migraine prevention efficacy is improved, but immune reactions and side effects worsen

Engineering Contradiction:

Improvemigraine prevention efficacyVSAvoidimmune reactions and side effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the treatment approach by dividing the head and neck region into multiple injection zones (frontalis, corrugator, procerus, occipitalis, temporalis, trapezius, and cervical paraspinal muscles), allowing distributed administration of neurotoxin to achieve comprehensive migraine prevention while reducing the concentration of toxin at any single site, thereby minimizing local and systemic side effects

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by selectively administering neurotoxin to specific muscle groups and trigeminal nerve distribution areas that are most relevant to migraine pathophysiology, rather than uniform distribution. This targeted approach ensures efficacy in migraine-prone regions while avoiding unnecessary toxin exposure in other areas, reducing overall side effect burden

Inventive Principle:

Principle #3Local quality

2Reliability

If numerous injections are administered to treat chronic migraine, then treatment coverage is improved, but treatment complexity and patient burden worsen

Engineering Contradiction:

Improvetreatment coverageVSAvoidtreatment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple injection sites into a coordinated treatment protocol that targets both trigeminal nerve distribution areas and cervical paraspinal muscles. By combining these regions into a unified approach, the patent achieves comprehensive treatment coverage while streamlining the administration process into a manageable single-session protocol rather than multiple separate treatments

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent applies multi-functionality by designing an injection protocol that simultaneously addresses multiple migraine mechanisms: blocking trigeminal nerve pain pathways, relaxing cervical muscle tension, and preventing pericranial muscle spasms. This single treatment session performs multiple therapeutic functions, reducing the need for separate treatments and simplifying overall patient management

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If high dosage of neurotoxin is used, then migraine prevention effectiveness is improved, but muscle weakness side effects worsen

Engineering Contradiction:

Improvemigraine prevention effectivenessVSAvoidmuscle weakness

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent segments the neurotoxin distribution across multiple muscle groups (frontalis, corrugator, procerus, occipitalis, temporalis, trapezius, and cervical paraspinal muscles), allowing the total effective dose to be distributed throughout the head and neck region. This segmentation prevents excessive toxin concentration in any single muscle, maintaining migraine prevention effectiveness while minimizing localized muscle weakness and ptosis

Inventive Principle:

Principle #1Segmentation

4Reliability

If traditional injection protocol is used, then migraine treatment is achieved, but total neurotoxin dose and number of administrations worsen

Engineering Contradiction:

Improvemigraine treatmentVSAvoidtotal neurotoxin dose

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the administration parameters by incorporating trigeminal nerve saturation injections into the protocol, which provides enhanced migraine prevention with lower total neurotoxin doses. The trigeminal nerve-rich areas require smaller volumes compared to traditional extensive muscle injections, allowing reduced overall dosing while maintaining or improving treatment effectiveness
