Solution Overview

Problem

Existing pulsed broadband radiation systems lack the necessary control and precision in delivering radiation profiles for industrial processes like composite manufacturing, thermal processing, cleaning, and sintering, as they do not allow for flexible adjustment of radiation intensity and direction at the target area.

Innovation Solution

A system comprising a pulsed broadband radiation source, such as a flashlamp, and a light guide with movable portions that can reflect and focus radiation to achieve a predetermined radiation profile at the target area, utilizing a light guide with reflective coatings and adjustable geometry to direct and concentrate radiation effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed light guide is used to guide radiation from the pulsed broadband radiation source, then the system structure is simple, but the radiation intensity and direction cannot be adjusted flexibly at the target area

Engineering Contradiction:
Improveadjustability of radiation intensity and directionVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light guide is designed with movable portions that can be adjusted relative to the pulsed broadband radiation source. The actuator enables dynamic repositioning of the light guide to change radiation direction and intensity at the target area, transforming a static system into a dynamic one that adapts to different processing requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The light guide is divided into multiple portions, with at least one portion being movable relative to the radiation source. This segmentation allows independent adjustment of different sections of the light guide, providing flexible control over radiation distribution while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If the light guide is made movable with actuators, then precise control over radiation profile is achieved, but the device complexity and cost increase

Engineering Contradiction:
Improveprecision of radiation profile controlVSAvoidactuator and control system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The actuator enables precise positioning of the movable light guide portion, allowing accurate control over radiation profile at the target area. The dynamic adjustment capability provides fine-tuned control of radiation intensity and direction while maintaining manageable system complexity through targeted actuation rather than full system complexity.

Inventive Principle:
Principle #15Dynamics
