Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser processing devices struggle to effectively suppress the adhesion of dust or debris to the output measuring means, which impairs the accurate detection of laser beam output.
Innovation Solution
A housing with a chamber and a beam-transparent member that allows the energy beam to pass, along with a gas supply port to maintain a higher pressure inside the chamber, preventing dust from adhering to the sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor is exposed to detect the energy beam, then the detection function is enabled, but dust adhesion occurs on the sensor
Solution Approach 1:
The housing is divided into a chamber that encloses the sensor, separating the detection space from the external environment. This segmentation allows the sensor to remain protected while still enabling beam detection through the beam-transparent member.
Solution Approach 2:
A beam-transparent member is introduced as an intermediary between the energy beam and the sensor. This mediator allows the beam to pass through to reach the sensor while simultaneously blocking dust particles from reaching the sensor surface.
2Object-affected harmful factors
If a closed chamber is used to protect the sensor, then dust adhesion is suppressed, but the energy beam cannot reach the sensor
Solution Approach 1:
The beam-transparent member is selectively applied only where the energy beam needs to pass through the housing wall. This local quality modification allows transparency to the beam at the beam interaction point while maintaining the protective enclosure elsewhere.
Solution Approach 2:
The beam-transparent member serves as a mediator that selectively transmits the energy beam while blocking dust particles. This intermediary material has the dual property of being transparent to the beam wavelength while being opaque to particulate matter.
3Object-affected harmful factors
If the beam-transparent member is fixed permanently, then the protective function is maintained, but replacement and maintenance become difficult
Solution Approach 1:
The beam-transparent member is designed with dynamic mounting characteristics, allowing it to be easily inserted and removed from the housing. This dynamic design enables maintenance and replacement without requiring complex disassembly procedures while maintaining the protective function during normal operation.
Solution Approach 2:
The beam-transparent member is designed as a separable component that can be extracted from the housing for replacement. This extraction capability allows the beam-transparent member to be removed, cleaned, or replaced independently while leaving the main housing and sensor assembly intact.
