Skin Treatment Light Channel Partition for Multi-Source Light Loss

Solution Overview

Problem

Existing skin treatment devices face issues with light loss and interference between multiple light sources due to their layout, leading to reduced light energy output and difficulty in transmitting light to the outlet, which affects treatment efficacy.

Innovation Solution

The device incorporates a partition member that divides the light emitting channel into sub-channels, each paired with a specific light source, reducing light interference and loss, and a reflective member with protrusions to prevent light blocking between adjacent sources, enhancing light concentration and output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple light sources are arranged in the housing with structures between light source and light outlet, then different types of light can be generated for skin treatment, but light loss increases and light concentration decreases during propagation

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The light emitting channel is segmented into multiple sub-channels using partition members. Each sub-channel is dedicated to a specific light source, preventing light from different sources from mixing and interfering with each other. This segmentation maintains light concentration and reduces energy loss while allowing multiple types of light to be emitted simultaneously through different sub-channels.

Solution Approach 1:

The light emitting channel is segmented into multiple sub-channels using partition members. Each sub-channel is dedicated to a specific light source, preventing light from different sources from mixing and interfering with each other. This segmentation maintains light concentration and reduces energy loss while allowing multiple types of light to be emitted simultaneously through different sub-channels.

Solution Approach 2:

Partition members are introduced as intermediary structures within the light emitting channel. These partition members physically separate the light paths of different light sources, acting as mediators that prevent harmful light interference while allowing each light source to function independently and effectively.
