Solution Overview

Problem

Existing ultraviolet light sterilization devices for fluid channels are large and complex due to the need for multiple lenses and precise optical axis adjustments, making them difficult to miniaturize and maintain.

Innovation Solution

A light source module device with a reflector and a cap-like optical member that reflects and transmits, condenses, or diffuses ultraviolet light, allowing for controlled light distribution with a simple and compact structure, and a fluid sterilizing device with sealing members to prevent fluid leakage and protect against ultraviolet degradation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If three lenses are used in the adjustment mechanism to control light distribution, then the ultraviolet light transmission efficiency is improved, but the device size increases and structural complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent combines multiple optical functions (light distribution control, condensing, and diffusing) into a single integrated optical member with a cap-like shape. This optical member includes a light distribution control portion, a condensing portion, and a diffusing portion all in one component, eliminating the need for multiple separate lenses and their adjustment mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The optical member serves multiple functions simultaneously: it controls light distribution angle, condenses ultraviolet light, and diffuses light. This multi-functional design replaces what previously required three separate lenses, simplifying the overall structure while maintaining or improving ultraviolet light transmission efficiency.
