Impregnated Electrode Ring for Precise Skin Treatment Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin treatment devices face challenges in accurately dosing active ingredients and require manual handling of active substances, leading to contamination and inefficient use of creams.
Innovation Solution
A ring with an absorbent carrier material impregnated with a precisely measured amount of active substance, which can be easily attached to the device without wetting hands, ensuring the active ingredient is applied directly to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of active substance is used, then application flexibility is maintained, but hand contamination occurs and requires cleaning
Solution Approach 1:
The patent introduces a ring as an intermediary component that holds the active substance and transfers it to the electrode without direct hand contact. The ring acts as a mediator between the active substance and the user's hand, eliminating contamination while maintaining application flexibility.
Solution Approach 2:
The invention segments the application system into distinct components: the ring holding the active substance, the electrode, and the device body. This segmentation allows the ring to be handled separately, preventing hand contamination of the active substance while maintaining ease of application.
2Reliability
If cream is applied before device handling, then active ingredient delivery is enabled, but hands must be cleaned to ensure safe grip
Solution Approach 1:
The ring with pre-measured active substance is prepared in advance and attached to the electrode before use. This preliminary preparation eliminates the need for manual cream application and subsequent hand cleaning, while ensuring reliable active ingredient delivery during treatment.
3Quantity of substance
If sponge is soaked and placed on electrode manually, then active substance application is achieved, but hand contamination with active substance occurs
Solution Approach 1:
The ring serves as an intermediary that holds the soaked sponge or carrier material with active substance. Instead of handling the soaked material directly, the user handles the ring, which prevents hand contamination while ensuring proper quantity of active substance is applied to the electrode.
4Measurement precision
If precisely measured active ingredient is used, then dosage accuracy is improved, but application complexity increases
Solution Approach 1:
The ring is pre-filled with a precisely measured amount of active substance or pre-soaked carrier material during manufacturing. This preliminary measurement eliminates the need for complex dosing procedures during application, maintaining dosage accuracy while simplifying the user application process.

AI summary
To simplify the handling of a skin treatment device (1), the invention provides that a ring (10) is attached to the cap (5) of the device, which forms the skin electrode (4). This ring is impregnated with a carrier material for an active substance. It preferably has the shape of a strip (13) and stretches over the head of the cap (5), which is placed on the skin. This ensures that a precisely measured amount of active substance is located between the skin electrode (4) and the skin. Since the curves (12) of the oval ring (10) are exposed, it can be grasped without contaminating the hands with the cream containing the active substance. The rings (10) with the impregnated carrier materials are supplied in blisters (20).
