Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CNC-type carpentry machines are not adaptable to machine beams larger than 16 meters, requiring additional space and adaptations that increase machine dimensions and compromise stability and precision.
Innovation Solution
A CNC carpentry machine with movable barriers and lateral walls that adjust to the beam's dimensions, using sensors and a control logic unit to expand or reduce the loading/unloading area, ensuring stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine is designed to accommodate larger beams (greater than 16 meters), then the adaptability of the machine improves, but the overall dimensions of the machine increase and stability decreases
Solution Approach 1:
The patent applies the dynamics principle by making the protective lateral walls movable rather than fixed. The walls can be repositioned along the main direction of the work center using a positioning system, allowing the machine to adapt its configuration for different beam sizes while maintaining a compact base structure. This dynamic adjustment enables the machine to accommodate beams larger than 16 meters without permanently increasing its overall dimensions, thereby preserving stability while improving adaptability.
2Adaptability or versatility
If additional roller conveyor is added to increase machine dimensions for large beams, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the protective structure into separate movable lateral walls that can be independently positioned. Instead of adding a complex additional roller conveyor system, the invention segments the protective enclosure into adjustable components that can be reconfigured for different beam sizes. This reduces device complexity while maintaining adaptability, as the segmented walls can be moved to accommodate various beam dimensions without requiring an entirely separate conveyor system.
3Manufacturing precision
If the machine base is fixed directly to the ground, then the manufacturing precision improves, but the adaptability to different beam sizes decreases
Solution Approach 1:
The patent maintains a fixed base connected to the ground for stability and precision, while applying dynamics to the protective lateral walls that can move along the main direction of the work center. This allows the machine to maintain high machining precision through its fixed base connection while simultaneously adapting to different beam sizes through the movable walls. The fixed-base movable-wall combination resolves the contradiction between precision and adaptability.
