Specimen Discharge Planning for TAT-Critical Inspection Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional specimen inspection automation systems face congestion and prolonged Turn Around Time (TAT) due to increased emergency specimens, leading to delays in result reporting, especially when the proportion of emergency specimens exceeds general specimens, impairing the effectiveness of timing and order adjustments in device loading and unloading.
Innovation Solution
A specimen inspection automation system with an instruction reception unit, discharge planning unit, discharge specimen storage device, discharge instruction unit, and discharge mechanism unit to manage and prioritize specimen discharge, allowing for automatic or manual processing to minimize TAT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection methods are used, then flexibility in handling various defect types is maintained, but inspection speed and productivity are limited
Solution Approach 1:
The inspection system is divided into multiple independent modules including illumination units, imaging units, and control units that can function independently yet coordinate together. This segmentation allows the system to achieve high automation and inspection speed while maintaining manageable complexity through modular design.
Solution Approach 2:
The automated inspection system is designed to handle multiple defect types (foreign matter, stains, scratches, dents) using a unified multi-functional platform. The system can inspect various specimen surfaces (vehicle body panels, glass, metal sheets) with the same core technology, achieving high productivity without proportionally increasing system complexity.
2Reliability
If automated inspection systems are implemented, then inspection speed and consistency are improved, but system complexity and initial investment increase
Solution Approach 1:
The system incorporates feedback mechanisms where inspection results are automatically analyzed and used to adjust inspection parameters. The control unit receives imaging data, processes it through pattern recognition algorithms, and provides feedback for consistent defect identification across multiple specimens, ensuring reliable and repeatable inspection results.
Solution Approach 2:
Manual mechanical inspection processes are replaced with automated imaging and optical systems. The system uses cameras, illuminators, and computer vision algorithms to substitute human operators, achieving consistent inspection quality while reducing dependency on manual labor and associated variability.
3Adaptability or versatility
If multiple inspection devices are deployed to cover all defect types, then comprehensive inspection capability is achieved, but device complexity and space requirements increase
Solution Approach 1:
A single automated inspection system is designed to detect multiple defect types (foreign matter, stains, scratches, dents) using unified imaging and analysis capabilities. The system adjusts inspection parameters and algorithms based on the target specimen and defect type, eliminating the need for multiple specialized devices while maintaining comprehensive inspection coverage.
Solution Approach 2:
The inspection system dynamically adapts its parameters and configuration based on the inspection requirements. The control unit can adjust illumination intensity, imaging magnification, and analysis algorithms in real-time to optimize detection of different defect types, providing versatile coverage without requiring fixed specialized equipment for each defect category.

AI summary
The present invention can report an inspection result within a prescribed time, and can respond to a sudden inspection result report request, even if a large number of urgent specimens have been input. The present invention comprises: an instruction reception unit 701 that receives TAT information and a discharge instruction; a TAT management unit 401 that manages TAT remaining time; a discharge planning unit 204 that determines the necessity of discharging a specimen for which the instruction was issued with the discharge instruction; a discharge specimen memory device 222 that memorizes the specimen for which discharge was planned by the discharge planning unit; a discharge instruction unit 704 that creates a discharge destination for the specimen memorized in the discharge specimen memory unit, and a conveyance route to the discharge destination; and a discharge mechanism unit 603 that discharges the specimen for which the instruction was issued by the discharge instruction unit. Even for a specimen which is caused to wait for processing due to the occurrence of specimen congestion and for which there is a risk of an inspection result reporting delay, an inspection result can be reported within a prescribed time by switching from automatic processing by the system to manual processing by an operator.
