Solution Overview

Problem

Existing support plates for bakery products face issues with humidity and gas release during fermentation and cooling stages, leading to cracks and unsatisfactory texture, while perforated plates cause product marking, which is perceived as industrial and of poor quality.

Innovation Solution

A support plate device featuring a metallic sheet with micromesh, having a passage opening of 130-750 µm and a void surface area of 17-60% of the total surface, which reduces product marking and ensures effective moisture evacuation without industrial appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a solid sheet is used as support material, then the mechanical strength and rigidity are improved, but humidity and gas cannot escape during fermentation and cooling, leading to cracks and unsatisfactory texture

Engineering Contradiction:
Improvemechanical strengthVSAvoidcracks and unsatisfactory texture
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent applies a perforated sheet material with specifically designed hole distribution and dimensions. The sheet contains holes with diameters between 1.8-3mm arranged in a regular pattern, providing void space for humidity and gas evacuation during fermentation and cooling stages while maintaining mechanical strength for supporting dough pieces throughout the baking process.

Inventive Principle:
Principle #31Porous materials

2Object-generated harmful factors

If a perforated sheet is used to allow humidity evacuation, then moisture escape is improved, but product marking occurs on the bottom surface, giving an industrial appearance

Engineering Contradiction:
Improvemoisture evacuationVSAvoidproduct appearance
Core Design Contradiction:
Object-generated harmful factorsVSShape

Solution Approach 1:

The patent implements local quality by creating zones of different perforation densities across the sheet surface. The sheet has a first zone with higher hole density for effective moisture evacuation and a second zone with lower hole density or different pattern to minimize marking on the product bottom. This selective distribution allows the sheet to perform different functions in different areas: moisture removal where needed and smooth contact where appearance matters.

Inventive Principle:
Principle #3Local quality

3Object-generated harmful factors

If the void surface area is increased to improve moisture evacuation, then humidity escape is improved, but the structural integrity and rigidity of the plate deteriorates

Engineering Contradiction:
Improvehumidity evacuationVSAvoidstructural integrity
Core Design Contradiction:
Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent optimizes parameters by carefully controlling hole diameter (1.8-3mm), hole density, and void surface area percentage to achieve the right balance. The sheet is designed with a specific void surface area range that provides sufficient moisture evacuation capability while maintaining adequate structural integrity to support dough pieces during handling and baking without excessive deformation or collapse.

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 support plate device effectively prevents product marking and ensures optimal moisture evacuation, maintaining a quality appearance reminiscent of artisanal manufacturing.

Implementation Method 1

the humidity and gas, necessarily released at the bottom of the dough pieces during the manufacturing process of bakery products, cannot escape through a solid sheet

Methodology Applied
Scientific EffectEvaporation: Evaporation

Implementation Method 2

The space between the cells or housings that a plate contains allows the flow of air from the oven to pass in order to guarantee optimal cooking

Methodology Applied
Scientific EffectDiffusion: Diffusion
