Dermal Enhancement Injection with Double-Gloved Sculpting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for dermal enhancement and soft tissue filling lack effective techniques for administering and molding materials to achieve desired orientations, particularly for addressing facial lipoatrophy and skin irregularities.
Innovation Solution
The methods involve injecting materials like polylactic acid, hyaluronic acid, or hydrogel using techniques such as soft tissue fanning, parallel injection, layering, and serial puncture/bolus, along with sculpting and molding techniques using double-gloved hands with metal fingertip plates to achieve desired dermal enhancement and soft tissue filling.

Engineering Contradiction Analysis
1Manufacturing precision
If traditional injection methods are used for dermal enhancement, then material can be administered to the patient, but the material cannot be precisely controlled to achieve desired orientation and distribution
Solution Approach 1:
The injection process is segmented into multiple controlled steps: inserting the needle at a specific angle, advancing to a target depth, injecting material while retracting, and repeating at angled intervals. This segmentation allows precise control over material distribution and orientation while maintaining operational clarity through standardized repetitive actions.
Solution Approach 2:
The needle is pre-positioned at a specific angle (e.g., 10-20 degrees) relative to the prior injection track before each injection. This preliminary angular positioning ensures that subsequent material deposition occurs at the desired orientation without requiring complex real-time adjustments during the injection process.
2Manufacturing precision
If multiple injection angles and techniques are used to achieve desired material orientation, then dermal enhancement precision is improved, but the complexity of the administration procedure increases
Solution Approach 1:
The injection procedure employs periodic angular advancements (e.g., 10-20 degree intervals) between successive injections. This periodic action creates a systematic fan-like pattern of material distribution that achieves comprehensive dermal coverage and desired orientation through repetitive, standardized cycles rather than complex variable adjustments.
Solution Approach 2:
The needle angle is dynamically adjusted between injections by advancing it at specific intervals (10-20 degrees) relative to the prior track. This dynamic angular adjustment allows the procedure to adapt and create three-dimensional material distribution patterns while maintaining a relatively simple repetitive injection mechanism.
3Manufacturing precision
If material is injected into horizontal plane while retracting needle, then material distribution is improved, but injection time increases
Solution Approach 1:
The injection action continues throughout the needle retraction process rather than being separated into distinct steps. Material is injected continuously while the needle withdraws, ensuring that the entire needle track receives material deposition. This continuous action maximizes material distribution efficiency and minimizes idle time between injection and withdrawal.
