Solution Overview

Problem

Current acne treatment methods, including devices, often have undesirable side effects, limited results, or are cumbersome and expensive, failing to provide a safe, user-friendly solution for effective treatment of acne vulgaris and other skin conditions.

Innovation Solution

A hand-held device combining light therapy with electrotherapy, utilizing multiple wavelengths of light (blue and infrared) and electrocurrent to treat acne, which synergistically enhances the therapeutic effects of each modality, improving acne treatment outcomes while minimizing side effects and allowing for home use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional acne treatment methods (topical antibiotics, oral antibiotics, hormonal treatments) are used, then acne lesions are treated, but undesirable side effects occur and bacterial resistance develops

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidside effects and bacterial resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines light therapy (phototherapy) and electrotherapy (microcurrent therapy) into a single integrated device. The light source emits specific wavelengths to target acne bacteria and reduce inflammation, while the electrodes apply microcurrent to enhance cellular function and promote healing. This combination approach provides synergistic effects that improve treatment reliability while avoiding the side effects associated with conventional pharmaceutical treatments.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If existing acne treatment devices are used, then therapeutic effects are achieved, but the equipment is large, expensive and difficult to use

Engineering Contradiction:
Improvetherapeutic effectVSAvoiduser-friendliness and portability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is designed as a compact, hand-held unit that integrates all necessary components (light source, electrodes, control circuitry) into a portable format. This segmentation from large clinical equipment to a personal device allows users to perform treatments at home, significantly improving ease of operation and accessibility while maintaining therapeutic effectiveness through targeted application to individual acne lesions.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple treatment modalities are combined in one device, then comprehensive treatment is provided, but device complexity increases

Engineering Contradiction:
Improvecombined light and electrotherapyVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is designed as a multi-functional unit where a single device performs both light therapy and electrotherapy functions. The light source provides phototherapy to target bacteria and reduce inflammation, while the electrodes deliver microcurrent for cellular stimulation and healing enhancement. This universal design allows comprehensive treatment of acne through multiple mechanisms without requiring separate devices, and the integrated control system manages the complexity internally while presenting a simple user interface.

Inventive Principle:
Principle #6Universality (Multi-functionality)
