Solution Overview

Problem

Existing methods for arranging sprinkling material on dough pieces, such as bread rolls or croissants, face issues with adhesion, particularly on the underside, and are inefficient for endless or soft dough strips, as they often require turning the dough, which can damage it and is not feasible for continuous production.

Innovation Solution

A device that allows sprinkling material to be applied to the underside of dough pieces without turning them, using a conveyor system with an adhesive application mechanism to ensure good adhesion, suitable for dough of indefinite length, and includes features like a sprinkling roller, adhesive roller, and collection systems to manage excess material and prevent fouling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the dough piece is turned over to arrange sprinkling material on the underside, then the sprinkling material can be arranged on the underside, but the dough piece and already sprinkled layer can be damaged

Engineering Contradiction:
Improvesprinkling material arrangementVSAvoiddough piece integrity
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

Instead of turning the dough piece upside down to access the underside, the invention inverts the approach by bringing the underside to the sprinkling surface while the dough piece remains in its original orientation. The dough piece is transported with the underside facing upward, allowing direct application of sprinkling material without flipping or turning operations that could damage the dough or previously applied layers.

Inventive Principle:
Principle #13The other way round (Inversion)

2Manufacturing precision

If the dough piece is turned over twice to arrange sprinkling material on the underside, then the sprinkling material can be arranged on the underside, but the device becomes unsuitable for dough pieces with unlimited length

Engineering Contradiction:
Improvesprinkling material arrangementVSAvoiddevice applicability to endless dough
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The invention inverts the conventional approach by not turning the dough piece at all. Instead, the transport system is designed to present the underside of the dough piece to the sprinkling surface while maintaining the dough piece's original orientation, enabling continuous processing of endless or very long dough strips without requiring flips or turns.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The device enables continuous sprinkling operation on endless dough strips by maintaining a constant processing orientation. The dough piece moves continuously through the device with the underside facing upward, allowing uninterrupted application of sprinkling material without stopping, turning, or reversing the dough flow.

Inventive Principle:
Principle #20Continuity of useful action

3Manufacturing precision

If a predetermined height is used for dough pieces to drop and reverse, then individual dough pieces can be provided with sprinkling material, but the device has to be reset for each product type

Engineering Contradiction:
Improvesprinkling material arrangementVSAvoiddevice reset requirements
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Instead of using a dropping and reversing mechanism that requires height adjustments and resets for different products, the invention uses a continuous transport system that presents the underside of dough pieces to the sprinkling surface. This eliminates the need for height adjustments and device resets when changing product types.

Inventive Principle:
Principle #13The other way round (Inversion)

4Reliability

If the dough piece is placed in a bed of sprinkling material without turning, then good adhesion occurs due to pressure from dough piece weight, but this requires a new device configuration

Engineering Contradiction:
Improvesprinkling material adhesionVSAvoiddevice configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention inverts the conventional sprinkling approach by placing the sprinkling material bed beneath the dough piece rather than sprinkling from above. The dough piece is transported with its underside facing upward and placed directly into the bed of sprinkling material, allowing the weight of the dough piece to press the sprinkling material onto the surface for reliable adhesion.

Inventive Principle:
Principle #13The other way round (Inversion)

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

Ensures effective adhesion of sprinkling material to the dough pieces, allowing for continuous processing of endless dough strips without damage, improving product quality and ease of handling in baking, while enabling even distribution and reuse of sprinkling material.

Implementation Method 1

means for applying to at least a part of the dough piece to be provided with the sprinkling material an adhesive

Methodology Applied
Scientific EffectAdhesive: Adhesive

Implementation Method 2

due to the pressure caused by the weight of the dough piece a good adhesion of the sprinkling material to the dough piece already occurs

Methodology Applied
Scientific EffectPressure caused by weight: Gravitation
