Solution Overview

Problem

Current botulinum toxin injections for facial wrinkles exhibit variability in results due to inconsistent injection locations, leading to undesired changes in facial appearance and patient dissatisfaction.

Innovation Solution

Customized patient masks with pre-formed holes or markers for precise injection locations, created using 3D imaging and printing, allowing for consistent and predictable treatment outcomes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional manual injection methods are used, then practitioner flexibility is maintained, but injection location consistency deteriorates leading to variable results

Engineering Contradiction:
Improveinjection location consistencyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by creating customized masks with pre-marked injection locations before the actual injection procedure. The masks are manufactured with precise anatomical landmarks and injection sites predetermined through 3D scanning and digital planning, allowing practitioners to simply follow the pre-established guide rather than manually determining locations during each procedure. This resolves the contradiction by maintaining practitioner flexibility in planning while ensuring consistent execution through pre-prepared guidance tools.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs copying by creating physical mask replicas from digital 3D scans of individual patient anatomy. These masks are customized copies that replicate the unique facial structure of each patient, including muscle attachments and anatomical variations. By using these copied anatomical models as injection guides, the system achieves precise and consistent injection locations that account for individual patient variability, while the copying process itself is automated through digital scanning and manufacturing technologies.

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If customized masks with pre-marked locations are used, then injection consistency is improved, but patient-specific anatomical variability is not adequately addressed

Engineering Contradiction:
Improveinjection location precisionVSAvoidpatient-specific customization
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by creating injection masks that are uniquely customized for each patient's specific anatomical features. Rather than using a generic template, the system performs 3D scanning of the individual patient's face, digitally plans injection locations based on their unique muscle structure and anatomy, and manufactures a mask with precisely positioned markings tailored to that patient's local anatomical characteristics. This ensures both high precision and patient-specific adaptability simultaneously.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs preliminary digital planning and 3D scanning for each patient before mask manufacturing. This preliminary action allows the injection locations to be precisely determined based on the patient's unique anatomy captured during scanning, ensuring both precision and patient-specific customization are achieved in the final mask design.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple injection sessions are performed without standardized guidance, then treatment flexibility is maintained, but result predictability deteriorates

Engineering Contradiction:
Improvetreatment result predictabilityVSAvoidtreatment planning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by creating comprehensive digital 3D models and injection plans during the initial patient consultation. These plans include precisely marked injection locations, dosage recommendations, and treatment protocols that are printed on customized masks. For subsequent treatment sessions, practitioners simply reference the pre-established plans on the masks, eliminating the need to recreate treatment protocols and significantly reducing planning time while maintaining consistent, predictable results across multiple sessions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback mechanisms where treatment results from previous sessions are reviewed and used to refine subsequent injection plans. The digital planning system allows practitioners to assess outcomes, adjust parameters, and update the customized masks for follow-up treatments, creating a continuous improvement loop that enhances predictability while efficiently utilizing prior treatment data.

Inventive Principle:
Principle #23Feedback
