Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing extruded products from vegetable parts, such as wooden pallet blocks, are inefficient and costly, with limitations in production output, contour flexibility, and material usage, particularly in creating complex shapes and profiles with uniform properties.
Innovation Solution
A method and device utilizing a compartment separating device to divide a rod-shaped, extruded strand with a binder into multiple products with varying contours and shapes, allowing for adjustable separation cuts along and transverse to the strand's axis, enabling the production of complex profiles with improved strength and surface properties, and optimizing production efficiency by reducing material usage and equipment needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single extrusion press produces one rod-shaped strand, then the equipment complexity is low, but the production output is limited
Solution Approach 1:
The single rod-shaped strand is divided into multiple individual extruded products through a compartment separating device with multiple separating units. This segmentation allows one extrusion press to produce multiple products simultaneously, increasing production output without adding more extrusion presses.
Solution Approach 2:
Multiple separating units are integrated into a single compartment separating device that processes one strand. This merging of separation functions into one device achieves high productivity while avoiding the complexity of multiple separate production lines.
2Adaptability or versatility
If the strand is cut with simple transverse cuts, then the manufacturing process is simple, but the product shape flexibility is limited
Solution Approach 1:
The compartment separating device allows dynamic configuration of separating cuts with variable orientations (transverse, longitudinal, oblique) and angles. This dynamic adjustability enables production of diverse product shapes including blocks, strips, and profiles with complex contours from a single rod-shaped strand.
Solution Approach 2:
Different separating units can apply different cutting orientations and angles to different sections of the strand, creating products with locally optimized shapes and properties. This allows customization of product geometry without complicating the overall manufacturing process.
3Adaptability or versatility
If the strand has a large cross-sectional area, then material usage is efficient, but the product variety is limited
Solution Approach 1:
The large cross-sectional area of the strand is segmented into multiple smaller products through the compartment separating device. This allows efficient material usage in the extrusion process while producing a variety of product sizes and shapes by dividing the strand into different numbers and configurations of individual products.
Solution Approach 2:
The separating device can adjust the number, orientation, and positioning of separating cuts to change product parameters. This enables production of various product types (blocks, strips, profiles) with different dimensions from a single strand with large cross-sectional area, maintaining material efficiency while increasing product variety.
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 method significantly increases production output and efficiency, allows for the creation of extruded products with complex, customizable shapes and enhanced properties, and reduces production costs by minimizing equipment and space requirements while ensuring uniform curing and quality.
Implementation Method 1
a rod-shaped, extruded strand of small vegetable parts provided with a binding agent
Implementation Method 2
separated and divided into several individual extruded products with a smaller frontal area using the claimed production technique. The pressed solid or hollow strand can be produced with a virtually endless length. Separating and dividing the strand can be done by means of a compartment separator. To separate and divide the strand, several separating cuts can be made one after the other, which are directed along and transverse to the longitudinal axis of the strand.

AI summary
The invention relates to a method and a device for producing extruded products (20) from a rod-shaped, extruded, solid or hollow strand (2) of wood components containing a binder, which preferably has an outer contour (11) that deviates from a flat, planar shape and has a defined end face (9). The strand (2) is separated and divided into several individual block- or strip-shaped extruded products (20) with a smaller end face (21) by means of a partitioning device (5).
