Foam contour-cutting machine with synchronized multi-tool system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contour-cutting machines for polyurethane foam operate at slow speeds due to limitations of cutting tools, leading to inefficiencies and reduced productivity, as increasing speed results in tool deformation and bowing.
Innovation Solution
A contour-cutting machine with multiple cutting tools mounted over vertical pillars, allowing simultaneous operation and customizable speed, featuring a platform on rails with a control unit to synchronize the movement of cutting tools and a pad for stabilizing the foam block, enabling efficient cutting of various shapes and contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the machine speed is increased to cut foam faster, then productivity is improved, but the cutting tool deforms and bows
Solution Approach 1:
The patent divides the cutting system into multiple independent cutting tools (at least two cutting tools with separate blades) that operate simultaneously on different portions of the foam block. This segmentation allows the cutting workload to be distributed across multiple tools, enabling faster overall processing while each individual tool operates at stable, controlled speeds that prevent deformation.
2Productivity
If multiple cutting tools are added to increase productivity, then production capacity is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cutting tools into a single integrated machine structure with a common frame, control system, and synchronized operation mechanism. This merging approach allows multiple cutting tools to function together as one coordinated system, increasing production capacity while avoiding the complexity of operating separate independent machines.
Solution Approach 2:
The machine design incorporates multiple cutting tools that can be configured to perform various cutting operations on foam blocks of different sizes and shapes. The system provides universal functionality through adjustable tool positions, interchangeable blades, and programmable control, allowing one machine to handle diverse cutting tasks that would otherwise require multiple specialized machines.

AI summary
A contour-cutting machine (100) for cutting a foam block, such as a polyurethane foam block into foam rows, such as pillows, has high productivity. The contour-cutting machine (100) has multiple cutting tools that can be operated simultaneously to cut the foam block. Each cutting tool has a blade that cuts through the foam block. For example, an upper cutting tool (116) and a lower cutting tool (118) mounted over a pillar (114) one above each other can be positioned at a predefined distance from each other and locked together. Each cycle of the process makes two cuts with the two cutting tools in the foam block.
