Digital Flatbed Cutter Parallel Cutting Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital flatbed cutters are inefficient when cutting arrays of printed images or designs, as they require sequential cutting actions, which prolong the cutting process.
Innovation Solution
The digital flatbed cutter incorporates a cutter plate with secondary knives or blades that can be removably mounted to the primary cutter assembly, allowing for simultaneous cutting actions parallel to the primary knife or blade, thereby reducing cutting time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential cutting actions are used with a single knife or blade, then the cutter structure remains simple, but the cutting time increases significantly when cutting arrays of printed images
Solution Approach 1:
The single cutting function is segmented into multiple parallel cutting functions by adding secondary knives or blades to the cutter plate. This allows simultaneous cutting of multiple images or designs in an array, directly improving cutting speed and productivity without requiring complete redesign of the head unit or movement system.
Solution Approach 2:
Multiple cutting functions are merged into a single cutter plate assembly that moves together with the primary cutter assembly. The secondary knives or blades are integrated onto the cutter plate, which is mounted to the primary cutter assembly, allowing all blades to move in unison and cut multiple elements simultaneously during a single pass.
2Loss of time
If multiple secondary knives or blades are added to cut multiple images simultaneously, then cutting time is reduced, but the cutter plate and mounting system become more complex
Solution Approach 1:
The cutter plate is designed as a universal platform that can accommodate multiple secondary knives or blades at different positions and orientations. This multi-functional design allows the same cutter plate structure to handle various cutting configurations for different array layouts, reducing the need for multiple specialized components.
Solution Approach 2:
The secondary knives or blades are essentially copies of the primary cutting element, replicated and positioned on the cutter plate to perform identical cutting functions on different parts of the workpiece simultaneously. This copying approach simplifies the design by using repeated, standardized components rather than creating entirely new cutting mechanisms.
3Adaptability or versatility
If the cutter plate is removably mounted to the primary cutter assembly, then versatility is improved for different cutting configurations, but the mounting system complexity increases
Solution Approach 1:
The mounting system transitions from a fixed to a dynamic configuration, allowing the cutter plate to be easily attached and detached from the primary cutter assembly. This dynamic mounting capability enables rapid reconfiguration for different cutting tasks while maintaining operational simplicity through standardized interfaces and quick-connect mechanisms.

AI summary
A digital flatbed cutter includes a flatbed on which a printed workpiece can be positioned. A head unit of the digital flatbed cutter is movable laterally along an x-axis direction and along a perpendicular y-axis direction in a parallel plane above the flatbed. A primary cutter head is mounted to the head unit and includes a primary cutter assembly with a primary knife or blade for cutting the workpiece. The primary cutter assembly movable along a z-axis direction that is normal to the plane and perpendicular to the x- and y-axes. A selected cutter plate is removably mounted to the primary cutter assembly and optionally to a secondary cutter assembly of the digital flatbed cutter. The cutter plate includes at least one mounting means, each mounting means being configured to mount a respective secondary knife or blade for cutting the workpiece in parallel with the primary knife or blade.
