Solution Overview

Problem

Existing inspection systems require manual operator intervention to determine the sorting destination of packages, leading to inefficiencies such as delayed sorting and misclassification of packages.

Innovation Solution

An inspection apparatus and program that utilize an EAD tag, camera, X-ray imaging, and ledger sheet readers to automate the sorting process, providing an operator with a verification screen that includes external appearance, X-ray, and historical data to efficiently sort packages into verified or non-verified categories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operator determination is used to sort packages, then flexibility in judgment is maintained, but sorting time increases and productivity decreases

Engineering Contradiction:
Improveoperator judgment flexibilityVSAvoidsorting speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The inspection apparatus performs self-service by automatically determining package sorting destinations using image recognition and machine learning, eliminating the need for manual operator intervention while maintaining accurate judgment through automated algorithms

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical system of manual operator judgment is replaced with an automated inspection apparatus that uses image capture, recognition processing, and machine learning algorithms to determine sorting destinations, thereby increasing productivity while maintaining judgment accuracy

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

2Adaptability or versatility

If manual sorting is performed, then operator discretion is maintained, but time consumption increases and throughput decreases

Engineering Contradiction:
Improveoperator discretionVSAvoidsorting time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The inspection apparatus uses feedback mechanisms where operators can correct automated sorting decisions, and these corrections are fed back into the machine learning system to improve future automated judgments, maintaining adaptability while reducing time consumption

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary automated sorting based on image recognition and historical data before operator review, allowing operators to only intervene when necessary and thereby reducing overall sorting time while maintaining discretion for complex cases

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automated inspection is implemented, then sorting speed increases, but system complexity increases

Engineering Contradiction:
Improvesorting throughputVSAvoidinspection system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The inspection apparatus is designed with multi-functionality, combining image capture, recognition processing, machine learning inference, and sorting control in a single integrated system, which increases productivity while managing complexity through consolidation rather than proliferation of separate components

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

AI summary

According to an embodiment, an inspection apparatus includes a communication interface and a processor. The communication interface acquires package information regarding a package being conveyed by a sorter that sorts the package and an operation signal generated based on an operation of an operator. The processor outputs reference information, based on past history in which inspection-result information indicating whether or not the package is a regulated-article candidate, generated based on the operation signal, and the package information are associated together, and the package information newly acquired.
