Solution Overview

Problem

Commercial production of baked goods often fails to replicate the consistent dual texture of homemade baked goods, particularly the soft inner structure and crisp surface, due to differences in small-batch vs. large-batch production and ingredient availability.

Innovation Solution

A method involving the creation of a leavened batter with a specific flour-to-water ratio followed by combining it with a second portion of flour to produce a dough, ensuring different hydration levels, which results in a dual textured baked good with a soft interior and crisp exterior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a standard dough formulation is used in commercial large-batch production, then productivity is improved, but the texture consistency and quality resemble homemade baked goods deteriorates

Engineering Contradiction:
Improvelarge-batch production efficiencyVSAvoidtexture consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The flour is divided into two distinct portions with different functions: first portion (40-60% of total flour) creates the soft interior structure, while second portion (40-60% of total flour) forms the crisp exterior. This segmentation allows each portion to optimize for its specific textural role, achieving dual texture in commercial production that mimics homemade quality while maintaining large-batch efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the baked good are given different flour treatments: the interior regions receive flour from the first portion that hydrates fully for softness, while the exterior regions receive flour from the second portion that remains less hydrated for crispness. This local differentiation of flour properties creates the desired dual texture throughout the product.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If flour hydration is increased to achieve soft interior texture, then the softness of the interior is improved, but the crispness of the surface deteriorates

Engineering Contradiction:
Improveinterior softnessVSAvoidsurface crispness
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The flour is segmented into two portions with different hydration levels. The first portion (40-60% of total flour) is fully hydrated to create the soft interior, while the second portion (40-60% of total flour) is less hydrated to form the crisp exterior. This segmentation resolves the contradiction by allowing different hydration states in different regions of the same dough system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dough exhibits local quality differences in hydration: the interior zones have high flour hydration (fully hydrated first portion) for softness, while the exterior zones have lower flour hydration (less hydrated second portion) for crispness. This spatial variation in hydration quality achieves both soft interior and crisp surface simultaneously.

Inventive Principle:
Principle #3Local quality

3Device complexity

If traditional single-flour dough methods are used, then the manufacturing process is simple, but the dual texture of soft interior and crisp surface cannot be achieved

Engineering Contradiction:
Improvedough preparation processVSAvoiddual texture achievement
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The dough preparation process is segmented into distinct stages: mixing the first portion of flour with liquids and leavening agents to form a hydrated base, then incorporating the second portion of flour to create the final dough. This segmentation adds only one additional mixing step while achieving the complex dual texture that traditional single-flour methods cannot produce.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first portion of flour is pre-hydrated with liquids and leavening agents before the second portion of flour is added. This preliminary action ensures the interior structure is prepared for softness, and the subsequent addition of the second flour portion creates the crisp exterior potential, achieving dual texture through a simple two-stage process.
