Flexible Material Cutting with Elastic Bristle Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting devices for flexible materials often fail to produce clean cuts due to material characteristics, such as thinness or flexibility, causing tears, wrinkles, or jams, and require different designs for various materials.
Innovation Solution
A cutting device equipped with a blade and elastic bristles that apply uniform pressure to the material, either vertically or horizontally, to stabilize and guide the flexible material during cutting, allowing for adjustable pressure distribution and adaptation to different materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid or flexible systems are used to hold down or guide the material, then the material is stabilized, but wrinkles are caused and correct cut is not ensured for all types of flexible materials
Solution Approach 1:
The patent applies local quality by using multiple discrete elastic bristles instead of a continuous rigid or flexible pressing system. Each bristle independently contacts and stabilizes the material at its specific location, distributing pressure locally across the cutting surface. This localized approach prevents wrinkles while maintaining stabilization, as the bristles adapt to the material's flexibility without creating the continuous pressure points that cause wrinkling with traditional systems.
Solution Approach 2:
The patent employs parameter changes by utilizing the elastic properties of the bristles, which can deform and adapt their pressure application based on the material being cut. The elastic bristles change their physical state (compression/extension) to match the flexibility of different materials, providing consistent stabilization without causing wrinkles. This dynamic parameter adjustment allows the same device to work with various flexible materials of different thicknesses and stiffness.
2Speed
If conventional cutting devices are used on thin or flexible materials, then the blade can move across the material, but the material tears, rips or wrinkles instead of being correctly cut
Solution Approach 1:
The patent applies preliminary action by positioning the elastic bristles to press the material against the base before the cutting action occurs. This pre-stabilization ensures the material is properly supported and taut in the cutting zone before the blade makes contact, preventing tears and wrinkles during the cutting process. The bristles maintain continuous contact to ensure the material remains stable throughout the blade's movement.
3Manufacturing precision
If different designs are used for different materials, then each material can be cut correctly, but the device complexity increases and requires adjustments
Solution Approach 1:
The patent implements universality by designing a single cutting device with elastic bristles that can effectively cut various types of flexible materials without requiring different designs or adjustments. The elastic bristles adapt to different material properties (thickness, flexibility, density) through their elastic deformation, providing consistent stabilization across multiple material types. This multi-functional approach eliminates the need for multiple specialized cutting devices while maintaining high cut quality for diverse flexible materials.

Data Source
AI summary
The cutting device includes a blade (1), in which either the blade (1) can move relative to a sheet of flexible material (4) or the sheet of flexible material (4) can move relative to said blade (1), and the blade (1) is associated with a plurality of independent flexible bristles (2), which press and stabilize the flexible material vertically and/or horizontally against a base (5) where the flexible material to be cut is supported. The device can be used to apply constant and well-distributed pressure on the flexible material in the cutting zone, preventing the material from wrinkling and securing the same in an optimal manner relative to the blade, thereby facilitating the cutting.
