Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spacing between cutters on cutting rollers is fixed, then the structure is simple and reliable, but the size and length of single-sheet fiber products cannot be adjusted
Solution Approach 1:
The cutting roller structure is made dynamic by making the cutter spacing adjustable rather than fixed. The distance between adjacent cutters can be changed to produce different single-sheet lengths, transforming a static structure into a dynamic one that adapts to different production requirements.
Solution Approach 2:
The physical parameter of cutter spacing on the cutting roller is made changeable. By adjusting the distance between adjacent cutters, the system can produce fiber products of varying lengths, allowing parameter optimization based on specific production needs without requiring multiple dedicated machines.
2Adaptability or versatility
If multiple machines are used to produce different folding forms, then each machine can be optimized for its specific function, but the total space usage and cost increase
Solution Approach 1:
The folding machine is designed with multi-functionality to perform various folding operations (C-fold, Z-fold, W-fold, and other complex folding forms) using a single integrated structure. This universal design eliminates the need for multiple dedicated machines, reducing space occupancy and investment costs while maintaining the capability to produce different folding forms.
Solution Approach 2:
Multiple folding functions that would traditionally require separate machines are merged into a single folding machine. The apparatus combines first and second folding rollers with adjustable configurations to achieve various folding patterns in one integrated system, consolidating multiple functions into a unified structure.
3Productivity
If the rotational speeds of cutting rollers are not controllable, then the mechanism is simpler, but the production efficiency and flexibility are reduced
Solution Approach 1:
The cutting roller system incorporates dynamic speed control, allowing the rotational speeds to be adjusted independently. This dynamic control enables optimization of production efficiency by matching roller speeds to specific production requirements while maintaining flexibility to adapt to different product specifications.
Solution Approach 2:
The speed control system incorporates feedback mechanisms to monitor and adjust the rotational speeds of cutting rollers. By measuring actual speeds and making real-time adjustments, the system maintains optimal performance and precision while providing the flexibility needed for efficient production of varying product specifications.

Implementation Method 1
The first cutting roller 121 and the second cutting roller 122 are each connected to a vacuum generation device (not shown), so that vacuum suction is applied to keep the first fiber product 11 and the second fiber product 12 attached to the roller surfaces.

AI summary
A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.
