Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood pressing devices require different types of presses for wood with small and large cross-sections, leading to high costs, additional space requirements, and low throughput speeds due to the need for separate equipment and processes.
Innovation Solution
A versatile pressing device with clamping units and endless conveyors that can generate both low and high pressing forces, allowing for continuous or cyclic processing of wood strands, depending on the cross-sectional area, using a single machine setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pressing device is used for both small and large cross-section wood, then device complexity and space requirements increase, but the patent resolves this by designing a versatile pressing device with adjustable clamping units that can handle both sizes
Solution Approach 1:
The pressing device is designed with clamping units that can be adjusted to accommodate both small and large cross-section wood pieces. The same pressing device structure serves multiple functions by adjusting the clamping unit configuration, eliminating the need for separate pressing devices for different wood sizes.
Solution Approach 2:
The clamping units are designed to be movable and adjustable rather than fixed. This dynamic design allows the pressing device to adapt its configuration based on the wood cross-section size being processed, enabling versatility without requiring completely different device structures.
2Productivity
If separate presses are used for small and large cross-section wood, then processing capability is optimized, but device quantity and space requirements increase
Solution Approach 1:
A single pressing device is designed to handle both small and large cross-section wood by incorporating adjustable clamping units. This eliminates the need for multiple separate presses, reducing space requirements while maintaining the ability to process different wood sizes effectively.
3Strength
If high pressing force is applied to large cross-section wood, then connection strength is improved, but throughput speed decreases due to cyclic processing
Solution Approach 1:
The clamping units are designed to be movable, allowing the pressing device to switch between continuous processing mode (for smaller pieces requiring lower force) and cyclic processing mode (for larger pieces requiring higher force). This dynamic capability allows optimization of both strength and throughput based on the specific wood being processed.
4Productivity
If continuous pressing is used for small cross-section wood, then throughput speed is high, but pressing force is insufficient for large cross-section wood
Solution Approach 1:
The pressing device incorporates movable clamping units that can be adjusted based on the wood cross-section size. For small cross-section wood, the device operates in continuous mode with lower pressing force for high throughput. For large cross-section wood, the clamping units are adjusted to provide higher pressing force in cyclic mode, ensuring adequate connection strength.

AI summary
The pressing device has at least one pressing unit (12, 24) through which the timbers (1) are transported. Their ends are abutted, and they are pressed against each other by the pressing units (12, 24). At least one first clamping unit (5) is positioned upstream of the pressing unit (12, 24), and at least one second clamping unit (35) is positioned downstream. The pressing device makes it possible to join the timbers (1) into a continuous strand with low pressing force. At high pressing forces, the timbers (1) are joined together in a timed manner to form a strand, with the clamping units (5) absorbing the required high pressing force.
