Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing automatic forming machines designed for large-size products are used to manufacture light, small, and thin pulp molding products, then the machine structure and process parameters are standardized, but the production cycle becomes excessive and manufacturing efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the machine structure adjustable rather than fixed. The forming machine can dynamically adjust its configuration to match different product specifications, allowing it to efficiently manufacture both large-size and light, small, thin products without being constrained by a standardized design optimized for a single product type.
Solution Approach 2:
The patent implements parameter changes by modifying key process parameters including suction time, squeezing time, dehydration time, and hot press shaping time according to the specific characteristics of the product being manufactured. This allows the machine to optimize its production cycle for different product types, thereby improving manufacturing efficiency while maintaining structural standardization.
2Manufacturing precision
If extended suction time, squeezing time, and hot press shaping time are used for light, small, and thin products, then the products are adequately formed, but the production cycle increases and energy consumption increases
Solution Approach 1:
The patent directly applies parameter changes by optimizing suction time, squeezing time, dehydration time, and hot press shaping time according to the specific characteristics of light, small, and thin products. This ensures adequate product forming while minimizing the production cycle and energy consumption, resolving the contradiction between manufacturing precision and time loss.
Solution Approach 2:
The patent applies partial action by adjusting the process parameters to the minimum necessary levels required for adequate product forming. Rather than using extended times that exceed what is needed, the machine parameters are precisely tuned to provide just enough processing time for quality formation, thereby reducing unnecessary time loss and energy consumption.
3Ease of operation
If the same machine parameters are used for both large-size and small-size pulp molding products, then the machine operation is simplified, but the production cycle cannot be optimized for different product specifications
Solution Approach 1:
The patent applies dynamics by implementing adjustable machine parameters that can be changed based on product specifications. The control system allows operators to dynamically adjust suction time, squeezing time, dehydration time, and hot press shaping time according to whether they are producing large-size or small-size products, thereby optimizing productivity without significantly complicating operation.
Solution Approach 2:
The patent implements universality by designing a machine that can handle both large-size and small-size products with optimized parameters. The machine maintains ease of operation through a unified control interface while providing multi-functionality in terms of parameter adjustment, allowing the same machine to be optimized for different product types without requiring separate machines or complex procedures.

AI summary
An automatic forming machine for a pulp molding product and a manufacturing method therefor. During manufacturing, a slurry suction mold immersed in a slurry box suctions a slurry to form a slurry layer, and then ascends to leave the slurry box to assemble with an upper hot pressing mold, which moves in from an external space, for extrusion to form a preform; then the slurry suction mold descends into the slurry box for a second round of slurry suction; the upper hot pressing mold suctions the preform and returns in a reverse direction to an original position; then a lower hot pressing mold ascends for assembling to hot press and shape the preform to form a pulp molding product, and the lower hot pressing mold suctions the pulp molding product and descends to the original position; and a material receiving mechanism then suctions the pulp molding product and leaves the lower hot pressing mold for separate collection. The automatic forming machine for a pulp molding product can perform, after slurry suction, rapid cold extrusion for dehydration and rapid hot-press forming, thereby increasing a manufacturing speed, shortening a production cycle, and reducing manufacturing cost.
