Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for gluing wooden lamellas into laminated plates are limited in dimension and do not enable continuous, high-speed production of laminated plates with optional widths and lengths without subsequent surface machining, and they often fail to adequately press and align lamellas of different lengths, preventing the use of fast-drying glues.
Innovation Solution
A modular press with segment pushers and pressure shoes that allow simultaneous longitudinal and transverse transport of wooden lamellas, enabling continuous gluing of optional dimensions into laminated plates of optional dimensions, with automatic force regulation and precise positioning, allowing for high-quality gluing without post-machining.

Engineering Contradiction Analysis
1Length of moving object
If wooden lamellas are pressed and glued in a limited pressing area width, then the pressing and gluing process can be completed within a compact machine structure, but the dimensions of the laminated plates are limited and cannot exceed the pressing area width
Solution Approach 1:
The press is divided into multiple work modules (first work module, second work module, etc.) that can be arranged in series. Each work module contains its own pressing area with pressing elements, allowing the machine to handle lamellas of various lengths by distributing the pressing operation across multiple segments. This enables production of laminated plates with dimensions exceeding that of a single pressing area.
Solution Approach 2:
The press structure extends in the longitudinal direction with multiple work modules arranged sequentially, transforming the pressing capability from a single-point operation to a multi-point distributed operation along the length of the lamellas. This dimensional extension allows handling of longer lamellas while maintaining a modular, manageable machine structure.
2Productivity
If a cyclic procedure is used for loading, pressing, and ejecting laminated plates, then the machine structure can be simplified, but fast continuous production is not enabled
Solution Approach 1:
Multiple work modules operate simultaneously in a continuous manner. While one module is completing pressing operation on a set of lamellas, another module is already receiving new lamellas for pressing. This overlapping continuous operation eliminates idle time between cycles and enables fast continuous production of laminated plates.
Solution Approach 2:
The first work module prepares and positions lamellas for pressing in advance while the second work module is already engaged in pressing operation. This preliminary preparation of materials and positioning of components ensures that pressing operations can proceed continuously without interruption or waiting time.
3Manufacturing precision
If wooden lamellas are transported without vertical guidance, then the transport mechanism can be simplified, but some lamellas uncontrollably deviate from the correct position
Solution Approach 1:
Guiding elements are introduced as intermediary components between the transport mechanism and the lamellas. These guiding elements passively constrain the lamellas to follow the correct transport path without requiring complex active control systems, achieving precise alignment while maintaining relatively simple device structure.
4Productivity
If individual lamellas are pressed sequentially one by one, then the pressing mechanism can be simple, but the production efficiency is reduced
Solution Approach 1:
Multiple pressing operations are merged into a single continuous process by arranging multiple work modules in series. Instead of completing one pressing operation entirely before starting the next, the system performs pressing operations on multiple sets of lamellas simultaneously across different modules, significantly increasing production speed while maintaining a manageable pressing mechanism through modular design.
