Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a short folding board is used in the conventional folding device, then the device structure is simple, but the paper is easily wrinkled and production quality is affected
Solution Approach 1:
The folding device is divided into multiple independent folding boards (first folding board, second folding board, third folding board) arranged in sequence. Each folding board performs a specific folding action on different portions of the paper web, allowing the system to achieve precise folding control without requiring each individual board to be excessively long, thus resolving the contradiction between device simplicity and folding quality.
2Device complexity
If a short folding board is used, then the device structure is simple, but the width or length of the folded paper handkerchief does not meet the regulated size and requires process pause to reset positioning
Solution Approach 1:
The folding boards are designed with adjustable positioning mechanisms that allow operators to modify the position and spacing of each folding board according to different production requirements. This dynamic adjustability enables the device to accommodate various regulated sizes without requiring process pauses for resetting, thereby maintaining high production efficiency while keeping the device structure relatively simple.
3Manufacturing precision
If multiple folding boards are added to increase folding precision, then the folding quality improves, but the device complexity increases
Solution Approach 1:
The folding function is segmented across multiple specialized boards rather than using a single complex board. Each folding board is relatively simple in structure but performs a specific folding task. This segmentation allows the system to achieve high folding precision through coordinated action of multiple simple components, resolving the contradiction between precision and complexity.
Solution Approach 2:
Multiple folding boards are combined in a sequential arrangement where each board contributes to the overall folding process. The first folding board performs initial folding, the second folding board performs intermediate folding, and the third folding board completes the folding sequence. This merging of multiple simple functional units achieves the precision of a complex single unit while maintaining structural simplicity.

AI summary
A folding machine for paper handkerchiefs is disclosed. The folding machine includes a longitudinal folding unit and a transverse folding unit, wherein the longitudinal folding unit executes a longitudinal folding procedure to a paper web to obtain a paper web with longitudinal folds, and the transverse folding unit receives the paper web with longitudinal folds from the longitudinal folding unit and cuts it into paper handkerchiefs before executing a transverse folding procedure to the paper handkerchiefs, thereby completing the folding process for paper handkerchiefs. After being folded longitudinally and transversely, the paper handkerchief is effectively reduced in size for packaging and is convenient for users to carry.
