Solution Overview

Problem

Novice users of light-based skin treatment devices face challenges in accurately maneuvering the device over the skin due to the discrepancy between the device tip and treatment window, leading to inconsistent coverage and suboptimal treatment results, with limited guidance and a cumbersome sensitivity test process.

Innovation Solution

A light-based skin care device with a training mode operating at a non-treatable flash fluence level, incorporating an IMU sensor for movement guidance and a processor to select the training mode, allowing users to practice device handling and movement without causing harm, and a user interface for external control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users practice with full light intensity, then treatment effectiveness is improved, but user safety is compromised due to potential skin damage

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidskin damage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system changes the light intensity parameter from full treatment level to reduced training level, allowing users to practice device handling and movement without the harmful effects of full-intensity light exposure. This parameter modification enables safe learning while preserving the ability to deliver effective treatment when needed.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If a sensitivity test process is implemented, then user safety is improved, but time consumption increases due to the manual testing procedure

Engineering Contradiction:

Improveskin reaction riskVSAvoidpreparation time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system performs sensitivity testing and user training in advance during the training mode before actual treatment begins. By completing these preparatory actions during the training phase, the system eliminates the need for time-consuming manual sensitivity tests later, while still ensuring user safety through pre-assessment.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If detailed movement guidance is provided, then treatment precision is improved, but device complexity increases due to additional sensors and processing

Engineering Contradiction:

Improvetreatment coverage accuracyVSAvoidsensor and processing requirements

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system uses an IMU sensor to detect device movement and provides real-time feedback to the user through visual or audible cues. This feedback mechanism guides users on proper device maneuvering without requiring complex mechanical guidance systems, maintaining treatment precision while managing device complexity through software-based solutions.
