Solution Overview

Problem

Existing corrugated food products face challenges in achieving uniform moisture after dehydration, requiring perforations that increase waste and processing time, and struggle to maintain strength and texture for use as dip carriers.

Innovation Solution

A high-amplitude corrugated food product with in-phase corrugated patterns on opposing sides, featuring a normalized area moment of inertia between 20 x 10^-8 m^3 and 160 x 10^-8 m^3, a dehydration factor of less than 1.7, and a 90°-to-0° hardness ratio and crispiness ratio of at least 2.6 and 2.75 respectively, allowing for uniform dehydration and enhanced textural characteristics without perforations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If corrugated food products are made with varying thickness to enable dehydration, then cooking uniformity is improved, but product strength and structural integrity deteriorate

Engineering Contradiction:
Improvecooking uniformityVSAvoidproduct strength
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

The patent applies local quality by creating corrugations with varying local thicknesses (peaks and valleys) within an overall uniform thickness product. The corrugations provide localized thinning for improved dehydration and cooking uniformity, while the overall uniform thickness and reinforced peak structures maintain product strength and structural integrity.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If perforations are added to corrugated food products to enable proper cooking, then dehydration uniformity is improved, but product complexity and processing time increase

Engineering Contradiction:
Improvedehydration uniformityVSAvoidproduct complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent extracts the dehydration function from separate perforations and integrates it directly into the corrugation structure itself. The corrugations create inherent pathways for moisture escape and heat penetration, eliminating the need for additional perforations and reducing product complexity while maintaining dehydration uniformity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If high-amplitude corrugations are created to enhance texture, then consumer appeal is improved, but dehydration time increases

Engineering Contradiction:
Improveconsumer appealVSAvoiddehydration time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent applies dimensionality change by creating three-dimensional high-amplitude corrugations that extend vertically from the product surface. These corrugations increase surface area and create multiple dehydration pathways, enhancing consumer appeal through unique texture while actually reducing dehydration time by providing more escape routes for moisture.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of manufacture

If uniform thickness is maintained in corrugated products, then manufacturing simplicity is improved, but cooking uniformity deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcooking uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies segmentation by dividing the product thickness into distinct regions (peaks, valleys, and intermediate zones) within the corrugation structure. This segmentation creates varying local thicknesses that promote uniform cooking and dehydration, while the overall uniform thickness is maintained for manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation
