Irregular Pizza Crust Press Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handmade pizza crusts lack uniformity in size, shape, bubble distribution, and texture, making them challenging for industrial handling and packaging, while machine-made crusts are less desirable due to their uniformity and lack of artisanal appearance.
Innovation Solution
An automated high-speed manufacturing process using a knuckle docking device and press assembly to create a pizza crust with a randomized appearance, mimicking handmade characteristics, including a built-up crust edge and thinner center, by embossing and cutting the dough to create a unique, artisan-like appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If handmade techniques are used to form dough crusts, then artisan appearance and consumer appeal are improved, but uniformity and ease of industrial handling deteriorate
Solution Approach 1:
The patent uses a mechanical system that copies the essential characteristics of handmade crust formation through randomized processes. The dough is subjected to controlled chaotic movements and irregular pressing patterns that replicate the appearance and texture of hand-formed crusts while maintaining manufacturability through automated equipment.
Solution Approach 2:
The invention introduces parameter variations in the crust formation process, such as varying pressure distribution, timing of formation steps, and randomization of shaping forces. These parameter changes create natural-looking variations in shape, thickness, and texture that mimic handmade crusts while allowing for consistent production through controlled automation.
2Productivity
If machine manufacturing techniques are used to produce pizza crusts, then productivity and uniformity are improved, but artisan appearance and consumer appeal deteriorate
Solution Approach 1:
The patent employs dynamic and flexible forming mechanisms that can adapt during the crust formation process. Rather than rigid, fixed molds, the system uses movable, adjustable components that can create varied shapes and textures, allowing high-speed production while maintaining artisanal appearance characteristics through controlled variability.
Solution Approach 2:
The dough itself is allowed to exhibit natural properties during formation, such as elastic rebound, bubble formation, and surface tension effects. The mechanical system provides minimal intervention, allowing the dough to self-organize into artisan-like patterns while the equipment maintains production efficiency through automated handling and consistent processing parameters.
3Shape
If handmade techniques are used to form dough crusts, then artisan appearance is improved, but manufacturing precision and consistency deteriorate
Solution Approach 1:
The patent deliberately introduces asymmetric and irregular features into the crust formation process to achieve artisan appearance. The system uses non-uniform pressure distribution, irregular forming surfaces, and randomized movement patterns that create natural-looking variations in shape and texture, accepting and even enhancing dimensional variability as a desired aesthetic characteristic rather than a defect.

AI summary
A press assembly for forming a food product where the press assembly includes a cutting die including a body that extends from a proximal end to a distal end. The proximal end has an irregular shape and a sharp edge configured to cut the food product into the irregular shape. The body has an interior surface surrounding an interior space. The press assembly further includes a pressure plate arranged within the interior space. The pressure plate includes a pressing surface including a first zone and a second zone surrounding and extending from the first zone at a taper angle such that an outer end of the second zone is recessed from an inner end adjacent the first zone. The cutting die and the pressure plate cooperate to press and cut the food product. The food product is also described.
