Needle Support System for Laser Cutting Paperboard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for laser cutting paperboard often result in burn marks and damage to the paperboard and equipment due to the laser beam, and require complex suction mechanisms that restrict efficient and consistent processing.
Innovation Solution
A support assembly with upright, spaced needles that protrude from a base, where the paperboard is placed horizontally, and a vacuum generator stabilizes it above the base, preventing scorching and allowing precise cutting while directing the laser beam away from the base to avoid heat damage, and using heat-resistant materials and anti-reflective coatings to manage the laser beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a laser beam is used for cutting paperboard, then cutting precision is improved, but burn marks are formed on the paperboard and the laser beam may damage the system
Solution Approach 1:
The patent introduces an intermediary substance (water-based slurry, gel, or liquid) between the laser beam and the paperboard surface. This intermediary absorbs the laser energy and converts it to a controlled reaction that prevents direct burning of the paperboard, while still enabling precise cutting. The intermediary acts as a buffer that mediates the interaction between the high-energy laser and the sensitive paperboard material.
2Object-affected harmful factors
If an under-laser raiser with protruding elements is used to prevent burn marks, then protection from burn marks is improved, but the system complexity increases due to required closed system and powerful suction mechanism
Solution Approach 1:
The patent extracts the harmful function (creating a closed suction system) and replaces it with a simple liquid intermediary that naturally prevents burn marks through its physical presence. The complex vacuum system with sealed bases and powerful suction mechanisms is removed, replaced by a straightforward liquid application system that achieves the same protective effect without the complexity.
3Stability of the object's composition
If a vacuum generator is used to stabilize paperboard on the under-laser raiser, then paperboard positioning stability is improved, but the processing efficiency decreases due to restricted material flow
Solution Approach 1:
The patent replaces the mechanical vacuum suction system with a liquid-based stabilization mechanism. The liquid intermediary not only prevents burn marks but also provides natural positioning stability for the paperboard through its physical properties. This substitution eliminates the need for complex vacuum generators and sealed systems, allowing for more efficient material processing while maintaining stability.

Function Achieved in This Case
Enables accurate and precise cutting of paperboard without scorching, protects the equipment from heat damage, and improves processing efficiency by maintaining a stable paperboard position and managing smoke and reflections effectively.
Implementation Method 1
The vacuum is intended to hold the paperboard, blanks, and/or other cut parts (of the paperboard, for example) in required position on the under-laser raiser
Implementation Method 2
When laser beam is used for cutting paperboards
Implementation Method 3
the laser beam may damage the system itself

AI summary
A support system for holding a sheet of material being cut by a laser has a base and a number of needles extending upwardly from the base. A vacuum generator or suction mechanism is in communication with a lumen in each needle to hold the sheet atop the bed of needles and spaced from the base so as to avoid scorching the sheet by the laser.
