Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment methods using high-frequency energy needles often cause damage to the epidermal layer due to excessive energy transmission, and struggle to supply energy uniformly to various depths of the skin, limiting the speed of skin regeneration and extending treatment periods.
Innovation Solution
A skin treatment needle with a conductive portion on its outer surface, featuring corrugations to distribute energy uniformly, and an insulating film to prevent excessive energy concentration, allowing for controlled energy delivery to multiple skin depths while minimizing epidermal layer damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If high-frequency energy is transmitted via a single electrode needle to the skin, then energy can be supplied to activate cellular tissues, but the energy is transmitted to not only the dermal layer but also the epidermal layer, causing damage to the epidermal layer
Solution Approach 1:
The needle surface is divided into different regions with distinct properties: a lower end conductive region for energy transmission to the dermal layer, and an upper end insulating region to prevent energy transmission to the epidermal layer. This local differentiation of conductive and insulating properties allows selective energy delivery to specific skin depths, solving the problem of epidermal damage while maintaining effective dermal treatment.
2Object-affected harmful factors
If an insulating film is applied on a needle surface with only a portion of the lower end removed to supply energy, then epidermal layer damage can be minimized, but energy can be locally supplied only via the lower end of the needle and thus cannot be supplied to various depths of the skin as required
Solution Approach 1:
The conductive region at the lower end of the needle is segmented into multiple independent conductive portions along the needle axis. Each conductive portion can be independently controlled to transmit high-frequency energy to different depths of the dermal layer. This segmentation allows versatile energy supply to various skin depths while the upper insulating region continues to protect the epidermal layer from damage.
3Productivity
If energy is supplied into skin tissue to increase the speed of skin regeneration, then treatment effectiveness is improved, but energy becomes excessively concentrated, extending the treatment period
Solution Approach 1:
The conductive region is divided into multiple conductive portions that can simultaneously transmit energy to different locations and depths within the dermal layer. This distributes the energy input across multiple sites rather than concentrating it at a single point, enabling more uniform and efficient stimulation of skin regeneration throughout the treatment area, thereby reducing overall treatment time.
