Contour Cutting Machine Single Blade Angled Wheels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contour foam cutting machines require two separate machines and operations to achieve precise cuts in different planes, leading to inefficiencies in space usage, handling, and accuracy due to the need for additional support and alignment of foam blocks during cutting.
Innovation Solution
A single-blade contour cutting machine with angled wheels allows the blade to transition between horizontal and vertical cutting planes, using synchronized drive wheels with increased contact area to maintain tension and prevent slippage, enabling secure holding and precise cuts with reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate machines are used for horizontal and vertical cutting, then cutting operations can be completed, but space requirements increase and handling complexity increases
Solution Approach 1:
The patent combines two separate cutting machines (horizontal and vertical cutters) into a single integrated machine. The machine includes a first cutting unit with a horizontal cutting blade and a second cutting unit with a vertical cutting blade, both mounted on the same machine frame. This merging allows the machine to perform both horizontal and vertical cutting operations in one location, eliminating the need for two separate machines and reducing space requirements.
Solution Approach 2:
The single cutting machine is designed with multi-functionality to perform both horizontal and vertical cutting operations. The machine can switch between different cutting modes by activating either the first cutting unit (horizontal) or the second cutting unit (vertical), making it a universal cutting solution that replaces two specialized machines.
2Adaptability or versatility
If two separate machines are used for horizontal and vertical cutting, then cutting operations can be completed, but handling and alignment accuracy decrease
Solution Approach 1:
By merging both cutting units into one machine, the foam block remains stationary on the same platform throughout both cutting operations. This eliminates the need to transport the block between machines, preventing position shifts and ensuring that the second cut aligns precisely with the first cut, thereby improving manufacturing precision.
3Reliability
If foam block is secured with taping or additional foam blocks, then movement is prevented, but the solution is insufficient and adds complexity
Solution Approach 1:
The patent introduces a clamping mechanism that secures the foam block from the sides (lateral dimension) rather than from the top or bottom. The clamps apply force horizontally to hold the block firmly in place during cutting, providing effective stabilization without the complexity of taping or stacking additional blocks.
4Productivity
If drive wheels have limited contact area with band knife, then the machine operates, but wheel life decreases due to high tension and narrow blade
Solution Approach 1:
The patent changes the physical parameters of the drive wheels by coating them with a high-friction material. This increases the coefficient of friction between the wheel surface and the band knife, allowing for better grip and distributed contact. The enhanced friction reduces localized stress and wear on the wheels, extending their service life while maintaining the high-speed cutting capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances cutting precision and consistency by allowing a single blade to perform both horizontal and vertical cuts, reducing the need for multiple machines and improving cutting speed, while extending the life of drive wheels through increased contact area and using durable steel-surfaced wheels.
Implementation Method 1
The wheels may be coated with rubber or a polyurethane material to ensure good friction and positive drive.

AI summary
A cutting machine having a first wheel pair and an opposite second wheel pair, an first vertical wheel, an opposite second vertical wheel, a first drive wheel, a second opposite drive wheel, and a single cutting blade, the first vertical and the second vertical wheels being configured to travel simultaneously and in a same horizontal direction, the first and the second wheel pairs being configured to travel simultaneously and in a same vertical direction, the first wheel pair having a first slanted wheel and the second wheel pair having a second slanted wheel, the single cutting blade being routed over all wheels such that at any moment during a travel of the single cutting blade while driven by the first and second drive wheels, a vertical blade portion extends between and can travel horizontally with the first vertical wheel and the second vertical wheel during vertical cutting and a horizontal blade portion extends between and can travel vertically with the first and second wheel pairs during horizontal cutting, wherein the slant of the first slanted wheel and the slant of the second slanted wheel prevents intersection of the horizontal blade portion and the vertical blade portion.
