Laser Booth Shielding Converging Faces Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for shielding coherent electromagnetic radiation, such as laser radiation, require complete encapsulation of the machining chamber, which leads to long cycle times due to the need to open and close transfer openings during the machining process, disrupting production.
Innovation Solution
A device with converging faces forming diametrically opposed openings, where the spacing varies to prevent direct radiation passage, reflecting radiation back towards the source, allowing for partial encapsulation and minimizing radiation escape without additional shielding means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If complete encapsulation of the machining chamber is implemented, then radiation safety is ensured, but cycle time increases due to opening and closing transfer openings
Solution Approach 1:
The encapsulation structure is segmented into multiple sections with selective openings. Instead of completely enclosing the chamber, the invention divides the structure to allow continuous transfer openings while maintaining radiation containment through strategic positioning of shielding elements at critical paths only.
Solution Approach 2:
A laser beam reflector is introduced as an intermediary element to redirect laser radiation away from transfer openings. This mediator component enables the system to maintain both open transfer pathways and radiation safety by changing the direction of harmful radiation through reflection.
2Object-affected harmful factors
If transfer openings are closed with rolling or lifting gates, then radiation containment is achieved, but productivity decreases due to interrupted machining operations
Solution Approach 1:
The gating mechanism is extracted and replaced with a fixed open transfer opening combined with a laser beam reflector. This removes the need for moving parts that interrupt production while maintaining radiation containment through the reflector's continuous operation.
Solution Approach 2:
The system enables continuous machining operations by maintaining open transfer openings throughout the process. The laser beam reflector operates continuously to redirect radiation, eliminating the start-stop cycles required by gating mechanisms and enabling uninterrupted productivity.
3Ease of operation
If lifting gates are opened and closed during machining, then workpiece transfer is enabled, but radiation safety is compromised during gate movement
Solution Approach 1:
The laser beam reflector is positioned in advance to intercept and redirect laser radiation before it can reach the transfer opening. This preliminary action of redirecting radiation ensures that even when transfer openings are open for workpiece handling, radiation safety is maintained without requiring gate movement.

Function Achieved in This Case
This solution effectively prevents radiation escape from the work chamber while allowing for continuous machining without complete encapsulation, reducing cycle times and ensuring safety by reflecting radiation back into the chamber.
Implementation Method 1

AI summary
The invention relates to a device for shielding coherent electromagnetic radiation, especially laser radiation. The device comprises at least two partially converging faces (6, 7) between which two opposite openings (8, 9) are configured. The distance of the faces (6, 7) between the two openings (8, 9) varies to such an extent that the electromagnetic radiation is prevented from going from the one opening (8) straight through the other opening (9).
