Solution Overview

Problem

E-commerce platforms face challenges in accurately assembling kits composed of multiple products, leading to customer dissatisfaction, returns, and increased shipping costs due to incorrect fulfillment by third-party partners, which is time-consuming and resource-intensive to manage.

Innovation Solution

A computer-implemented method and system for generating a product packaging model that includes selecting and arranging products within a kit, using 3D modeling to optimize packaging and automate error detection during the fulfillment phase, allowing for real-time verification of correct assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If third-party fulfillment partners manually assemble kits, then flexibility in fulfillment is maintained, but assembly accuracy decreases leading to errors

Engineering Contradiction:
Improvefulfillment flexibilityVSAvoidkit assembly accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system performs preliminary actions by generating a digital twin of the kit assembly process before actual fulfillment. This includes pre-defining the correct arrangement of products, packaging materials, and labels in a virtual environment, which then serves as a reference for automated verification during actual kit assembly by fulfillment partners.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a digital copy (digital twin) of the physical kit assembly process. This virtual model replicates the exact arrangement, packaging, and labeling specifications, enabling automated comparison and verification against the actual assembled kit using image recognition and computer vision technologies.

Inventive Principle:
Principle #26Copying

2Measurement precision

If automated verification systems are implemented, then assembly error detection improves, but system complexity increases

Engineering Contradiction:
Improveerror detection accuracyVSAvoidverification system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The digital twin system serves multiple functions: it stores the ground truth assembly specifications, provides real-time verification guidance to fulfillment partners, captures images of assembled kits, performs automated comparison, and generates verification reports. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated platform.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables fulfillment partners to perform self-verification of kit assembly by providing them with access to the digital twin and verification tools. The automated image recognition and comparison processes allow partners to independently verify their own work without requiring complex external inspection systems.

Inventive Principle:
Principle #25Self-service

3Loss of energy

If manual verification of kit assembly is performed, then resource consumption is low, but time consumption increases

Engineering Contradiction:
Improveverification resource consumptionVSAvoidassembly verification time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical verification processes with automated computer vision and image recognition systems. Cameras capture images of assembled kits, and software algorithms automatically compare these images against the digital twin specifications, eliminating the need for time-consuming manual inspection while consuming minimal computational resources.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Methods and systems for packaging a product offering of product items associated with a merchant account. A product packaging model is associated with a kit of product items having a selected packaging option. During assembly, one or more images of the kit are captured and image features are detected and compared to parameters specified in the product packaging model. An error notification is output if a deviation is detected between the detected image features and the parameters prescribed by the product packaging model.
