Solution Overview

Problem

Existing texture modified foods (tmf) lack aesthetic appeal, nutritional density, and are often not available in social settings, posing challenges for dysphagic individuals who may feel isolated and face swallowing difficulties due to their consistency and psychological effects.

Innovation Solution

A method involving dehydration, grinding, and rehydration of starch-based foods with a carrier to form a paste, which is then shaped and textured to resemble the original food, using additives like Xanthan gum for a smooth consistency, and packaged to maintain shape and nutritional integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional puree method (boiling/steaming and blending with liquid) is used, then the food becomes smooth and easy to swallow, but the product loses aesthetic appeal, nutritional density, and original texture

Engineering Contradiction:

Improveswallowing easeVSAvoidnutritional density

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent segments the processing into distinct stages: dehydration to remove water, grinding to create fine powder, carrier coating to prevent clumping, and controlled rehydration to form paste. This segmentation allows each step to optimize for its specific function rather than compromising overall quality through single-step blending.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary dehydration and grinding actions before rehydration. By removing water first and grinding to fine powder, the starch-based product is prepared in advance to absorb water uniformly during rehydration, preserving nutritional density while achieving smooth consistency without excessive dilution.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If traditional puree method is used, then the food becomes smooth consistency, but the product lacks aesthetic appeal and resembles monochrome pale paste

Engineering Contradiction:

Improvesmooth consistencyVSAvoidaesthetic appearance

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The patent changes the physical parameters of the starch-based product through controlled dehydration and rehydration cycles. By removing water to create dry powder and then rehydrating to controlled moisture content, the product achieves both smooth consistency and retained color/appearance characteristics that resemble the original food form.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If traditional puree method with dilution is used, then the food becomes easier to swallow, but the product loses nutrient density due to dilution effect

Engineering Contradiction:

Improveswallowing easeVSAvoidnutrient density

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts water from the starch-based product through dehydration to create a concentrated fine powder form. This extraction removes excess water that would otherwise require dilution during blending, allowing the product to be rehydrated to the necessary consistency without adding excessive liquid that would dilute nutrients.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If traditional blending with stock or cooking water is used, then the food achieves puree consistency, but the product becomes sticky and adheres to palate

Engineering Contradiction:

Improvepuree consistencyVSAvoidpalate adhesion

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a carrier substance as an intermediary during the rehydration process. This carrier mediates between the dry fine powder and water, controlling the hydration process to achieve smooth consistency without the sticky adhesion that occurs with traditional direct blending methods.

Inventive Principle:

Principle #24Intermediary (Mediator)
