Solution Overview

Problem

Conventional rounding machines for food dough, particularly those used for artisan bread, face issues with dough adherence, leading to insufficient rounding, uneven shapes, and damage due to friction and inadequate frictional force, especially with less elastic and heavier dough pieces.

Innovation Solution

A rounding machine with a pair of shaping plates that move along a specific locus with a longitudinal and widthwise component, featuring concave forming faces and protruding sections to facilitate horizontal rolling without linear contact, reducing adhesion and ensuring uniform shaping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional rounding machines use inclined guiding plates with friction-based horizontal rolling, then dough pieces can be rounded, but less elastic and heavy dough pieces (like artisan bread) adhere to the machine due to friction

Engineering Contradiction:
Improverounding effectVSAvoiddough adherence
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies curvature by designing the guiding plates with a specific inclination angle (α) between 0° and 45°, and positioning the pressing section at a specific height (h) above the conveying surface. This curved geometric configuration reduces the frictional contact between the dough and the guiding plates, preventing adherence while maintaining the rounding effect.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent introduces a vertical dimension by positioning the pressing section at a specific height (h) above the conveying surface, rather than having direct horizontal contact. This dimensional change allows the dough to be pressed and rounded without excessive frictional adhesion to the guiding plates.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If the same portion of dough is repeatedly pressed and kneaded by movable guiding plates, then the dough can be shaped, but the inner layers become uneven and residual air bubbles are not uniformly distributed

Engineering Contradiction:
Improveuniform shapeVSAvoiduniform inner layers
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by designing different sections of the guiding plates with specific functions: the pressing section at height (h) for shaping, and the inclined guiding plates for gentle guidance. This localized functional differentiation ensures uniform pressing without excessive kneading of the same portions, maintaining even inner layers and uniform air bubble distribution.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs dynamic motion by moving the guiding plates in a coordinated manner during the rounding process, rather than static pressing. This dynamic approach allows different portions of the dough to be pressed at different times, ensuring uniform shaping while maintaining even inner layers.

Inventive Principle:
Principle #15Dynamics

3Shape

If inclined guide plates are used to round dough pieces, then shaping can be achieved, but damage to the food-dough piece and stagnant dough pieces on the conveying device occur

Engineering Contradiction:
Improverounded shapeVSAvoidhandling reliability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent changes the parameters of the guiding plate configuration by setting the inclination angle (α) between 0° and 45°, and positioning the pressing section at a specific height (h). These parameter optimizations reduce excessive friction and pressure concentration, preventing dough damage and stagnation while achieving the desired rounded shape.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The machine effectively prevents dough adherence, ensures even and firm surfaces, and achieves uniform inner layers by minimizing friction and using centrally directed pressure for consistent shaping.

Implementation Method 1

the horizontal rolling of the food-dough pieces is caused by a frictional force between the guiding plates and the surfaces of the food-dough pieces
