Solution Overview

Problem

The decline of artisanal bakeries has led to a desire for bakery products with the quality of artisanal breads that can be freshly baked at distant points of sale without requiring extensive equipment or the expertise of an artisan baker, while existing methods result in products with less tasty crumb and harder crust due to freezing and double baking.

Innovation Solution

A stackable packaging system for transporting and proving fresh raw dough pieces, comprising a rigid plastic frame with air passages and a stainless steel support, allowing controlled cooling and minimizing condensation, which maintains the quality of the dough during transport and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If freezing and double baking are used to enable distant point of sale, then productivity and distribution range are improved, but product quality deteriorates with less tasty crumb and harder crust

Engineering Contradiction:
Improvedistribution rangeVSAvoidproduct quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The dough is prepared and proofed in advance at the production site, then rapidly cooled to 4°C to pause fermentation. This preliminary action allows the dough to be transported and stored for up to 48 hours while maintaining its quality, enabling distant point of sale without freezing or double baking.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention controls the temperature parameter by rapidly cooling the proofed dough to 4°C and maintaining it during transport. This temperature control prevents quality deterioration while enabling extended storage and distribution, resolving the contradiction between distribution range and product quality.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If artisanal bakery operations are maintained at point of sale, then product quality is improved, but device complexity and operational requirements increase

Engineering Contradiction:
Improveproduct qualityVSAvoidequipment requirements
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The complex artisanal bakery operations (kneading, proofing, temperature control) are extracted from the point of sale location and consolidated at a centralized production site. The point of sale only requires simple cooking equipment, dramatically reducing device complexity while maintaining product quality through the standardized packaging and transport system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The specialized packaging system acts as an intermediary that preserves the quality of artisanal dough during transport. The packaging with controlled air passages and insulation maintains the dough at 4°C without requiring complex equipment at the point of sale, bridging the gap between centralized production and simple point-of-sale operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of moving object

If extended transport and storage periods are implemented, then distribution flexibility is improved, but product quality deteriorates due to condensation and temperature variations

Engineering Contradiction:
Improvestorage periodVSAvoidproduct quality
Core Design Contradiction:
Duration of action of moving objectVSManufacturing precision

Solution Approach 1:

The packaging system controls the temperature parameter by rapidly cooling the dough to 4°C and maintaining it through the use of insulating materials and air passages. This parameter control prevents condensation and quality deterioration during extended storage periods of up to 48 hours.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The packaging uses a rigid plastic frame with flexible insulation layers and controlled air passages. This structure provides both mechanical protection and thermal insulation, maintaining the dough at the required temperature during extended transport and storage while preventing condensation issues.

Inventive Principle:
Principle #30Flexible shells and thin films
