Solution Overview

Problem

The production of waffles and waffle-like baked goods often results in a closed, smooth surface and a porous internal structure, leading to issues such as crumbling, rapid absorption of liquids, and reduced protective functions when coated, due to the open, large-pored edges created during processing, which are aesthetically unattractive and technologically unfavorable.

Innovation Solution

A waffle shaped body and baking plate device design where the baked products are connected via a thin separating web that is less than half the thickness of the baked product, allowing for efficient production and minimizing the open-pored surface exposure by using a baking plate device with gap sections that form a mold with smaller gap thickness than product thickness, enabling the baked products to be separated without damaging the closed outer surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If waffles are baked in hollow molds with evaporation openings to achieve high water content (55-66%), then a porous internal structure is formed, but the edges become open and large-pored which leads to increased crumbling and rapid absorption of liquids

Engineering Contradiction:
Improvewater contentVSAvoidstructural integrity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies local quality by creating different structural characteristics in different regions of the waffle. The separating webs have a specific thickness (0.5-2 mm) that is optimized for maintaining structural integrity at edges, while the core areas can have greater thickness for the desired porous structure. This regional differentiation allows the waffle to have both high water content in the interior and sufficient structural strength at the edges.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If separating cuts are made to divide baked products, then individual portions are obtained, but the open-pored structure is exposed leading to rapid absorption of liquid components

Engineering Contradiction:
ImproveportionabilityVSAvoidliquid absorption
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by pre-forming the waffle structure with optimized separating webs before any cutting or portioning takes place. The separating webs are designed with specific thickness (0.5-2 mm) and structural characteristics during the baking process itself, so that when subsequent separating cuts are made, the edges already have the necessary structural integrity to resist rapid liquid absorption.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If homogeneous waffle thickness is used throughout, then production is simplified, but the edges have excessive open-pored surface area which reduces protective function of coatings

Engineering Contradiction:
Improveproduction simplicityVSAvoidmoisture ingress
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent implements local quality by specifying that separating webs have a thickness of 0.5-2 mm, which is different from the typical homogeneous thickness used throughout the entire waffle. This localized variation in thickness allows the edges (separating webs) to have reduced open-pored surface area and improved structural properties, while the rest of the waffle can maintain homogeneous thickness for production simplicity.

Inventive Principle:
Principle #3Local quality
