Solution Overview

Problem

The delivery cost for orders containing both fresh and non-fresh products increases due to separate packaging, despite the potential for combined shipment, as most delivery costs are based on parcel count.

Innovation Solution

A packaging management method that classifies fresh products by temperature and determines which types can be packaged together with non-fresh products, optimizing packaging choices to minimize parcel count and maximize products per parcel (UPP) while ensuring product quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fresh products and non-fresh products are packaged separately, then product quality is maintained, but delivery cost increases due to higher parcel count

Engineering Contradiction:
Improveproduct qualityVSAvoiddelivery cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent combines fresh products and non-fresh products into a single packaging container when temperature conditions permit. The system determines compatibility based on temperature classification, and when compatible, merges the products into one parcel to reduce delivery cost while maintaining quality through proper temperature control during transit.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies different packaging approaches to different products within the same order based on their temperature requirements. Fresh products with similar temperature needs are grouped together, and non-fresh products are added to this group only when they share compatible temperature characteristics, creating locally optimized packaging solutions rather than universal packaging rules.

Inventive Principle:
Principle #3Local quality

2Loss of energy

If fresh products and non-fresh products are packaged together, then delivery cost decreases due to lower parcel count, but product quality may deteriorate due to temperature incompatibility

Engineering Contradiction:
Improvedelivery costVSAvoidproduct quality
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent changes the parameter of temperature classification to determine packaging compatibility. By categorizing fresh products into frozen, refrigerated, and room temperature groups, and comparing these parameters with non-fresh products, the system identifies compatible combinations. This parameter-based approach enables cost-effective combined packaging while preventing temperature-related quality deterioration through systematic compatibility assessment.

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If frozen products are packaged with non-fresh products, then parcel count is reduced, but quality deterioration occurs due to excessive cold temperature

Engineering Contradiction:
Improveparcel countVSAvoidproduct quality
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent extracts frozen products from the group of fresh products that can be combined with non-fresh products. By separating frozen products into a distinct category, the system prevents their combination with non-fresh products, thereby avoiding quality deterioration from excessive cold temperatures while still reducing overall parcel count through compatible combinations of refrigerated and room temperature fresh products with non-fresh items.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A packaging management method is disclosed. The method may be performed by a computing device, and may comprise: receiving an order of a customer including fresh products and non-fresh products; determining a type of fresh product packagable together with the non-fresh product among the fresh products as a target fresh product based on a result of classifying types of the fresh products according to a temperature; and automatically determining whether or not to package the target fresh product and the non-fresh product in the same packaging container.
