Solution Overview

Problem

Existing methods for preparing food products wrapped in dough limit shelf life to 6 days due to high-temperature cooking and lack of effective packaging solutions, leading to organoleptic and microbiological deterioration.

Innovation Solution

A food product comprising two or more edible ingredients, where an outer fermented dough body encloses an inner core, cooked at low temperatures below 130°C, allowing packaging before cooking and extending shelf life without freezing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-temperature cooking (>130°C) is used to prepare food wrapped in dough, then the food is cooked thoroughly, but the shelf life is limited to 6 days due to organoleptic and microbiological deterioration

Engineering Contradiction:
Improveshelf lifeVSAvoidorganoleptic and microbiological deterioration
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by cooking the food product at low temperature (below 130°C) for an extended period (at least 10 minutes) instead of high-temperature short-time cooking. This parameter change in the cooking process allows thorough cooking while preserving organoleptic qualities and extending shelf life without freezing or refrigeration.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies preliminary action by assembling the complete food product in its final packaging before cooking, rather than cooking first and then packaging. This preliminary assembly in the final package allows the low-temperature cooking process to penetrate the dough and cook the filling thoroughly while maintaining product integrity and extending shelf life.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If low-temperature cooking (<130°C) is used to extend shelf life and maintain organoleptic qualities, then the product shelf life is extended, but the cooking time must be increased to at least 10 minutes

Engineering Contradiction:
Improveshelf lifeVSAvoidcooking time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent resolves this contradiction by changing the cooking parameters: using low temperature (below 130°C) combined with extended cooking time (at least 10 minutes). This parameter combination achieves both extended shelf life and maintained organoleptic qualities while ensuring thorough cooking of the filling.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies nesting by placing the filling inside the dough in the final packaging configuration before cooking. This nested structure ensures efficient heat transfer from the dough outward to the filling, allowing thorough cooking at low temperature within the extended time frame without requiring additional processing steps.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of manufacture

If the food product is assembled in the final package before cooking, then shelf life is extended and convenience is improved, but the packaging must be sealable and suitable for low-temperature cooking

Engineering Contradiction:
ImproveconvenienceVSAvoidpackaging requirements
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by assembling the complete food product in its final packaging before cooking. This approach improves convenience and extends shelf life by eliminating post-cooking handling and repackaging, while the packaging requirements are met through selection of sealable containers suitable for low-temperature cooking processes.

Inventive Principle:
Principle #10Preliminary action
