Solution Overview

Problem

Existing devices for generating physical plasma using dielectric barrier discharges are complex and limited to local treatment of surfaces, particularly the scalp, making them unsuitable for treating larger areas effectively for hair loss or stimulating hair growth.

Innovation Solution

A device with a common high voltage terminal and elongated electrode bodies capacitively coupled to it, featuring dielectric spacers at the distal ends that project beyond the electrode surfaces to create defined discharge gaps, allowing for the generation of physical plasma over larger areas while preventing mechanical stress and irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If individual deformable electrode bodies with dielectric barriers are used for local plasma generation, then plasma can be generated locally on the scalp, but the device complexity increases and treatment area is limited

Engineering Contradiction:
Improvetreatment areaVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The device divides the treatment area into multiple zones with separate electrode bodies arranged in arrays, allowing simultaneous treatment of multiple scalp regions. Each electrode body can be independently controlled to generate plasma at specific locations, enabling both large-area coverage and localized treatment as needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Dielectric barriers are introduced as intermediary layers between the electrode bodies and the scalp surface. These dielectric barriers enable plasma generation without direct electrode-skin contact, reducing mechanical stress and irritation while maintaining effective treatment over larger areas.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If electrode bodies are pressed against the scalp to generate plasma, then plasma generation efficiency increases, but mechanical stress and irritation to the scalp occur

Engineering Contradiction:
Improveplasma generation efficiencyVSAvoidmechanical stress and irritation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Dielectric barriers serve as intermediary layers between the electrode bodies and scalp, enabling plasma generation through capacitive coupling without direct contact. This maintains high plasma generation efficiency while eliminating mechanical stress and irritation caused by pressing electrodes against the skin.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical contact-based plasma generation system with a capacitive coupling system using dielectric barriers. Instead of pressing electrodes directly against the scalp, the system uses electric fields through dielectric layers to generate plasma, substituting mechanical interaction with electromagnetic interaction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If a helmet with chamber is used to treat hair loss, then large area treatment is possible, but the overall construction becomes very complex

Engineering Contradiction:
Improvetreatment areaVSAvoidoverall construction
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Instead of using a single large helmet with chamber, the patent segments the treatment system into multiple electrode bodies with dielectric barriers that can be arranged in flexible arrays. This allows large-area treatment through modular configuration rather than requiring a complex enclosed helmet structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the fundamental operating parameters from requiring a sealed chamber environment to enabling plasma generation through dielectric barriers in direct or near-contact with the scalp. This parameter change eliminates the need for complex helmet enclosures while maintaining large-area treatment capability.

Inventive Principle:
Principle #35Parameter changes

AI summary

A device serves for generating physical plasma by means of dielectric barrier discharges with respect to a surface of an object. The device comprises a common high voltage terminal, and a plurality of electrode bodies that are capacitively coupled to the common high voltage terminal, that comprise an exposed electrode surface and a distal end each, and that are, in a main extension direction, elongated in parallel to one another towards their distal ends. The device further comprises spacers made of dielectric a d arranged at the distal ends of the electrode bodies, the spacers projecting beyond the exposed electrode surfaces of the electrode bodies by 1.0 mm to 5.0 mm in the main extension direction. The device may be part of a hair loss therapy apparatus.
