Lab Device Resource Validation Against Task Schedule
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laboratory devices often produce unreliable results when using resources with exceeded validity limits, leading to waste of samples and resources, and reduced productivity due to invalid resource combinations and prolonged task schedules.
Innovation Solution
Implementing a method for forward validation of resource validity against scheduled lab task completion times, which involves identifying resources, retrieving and validating their validity data against expected completion times, and generating a resource validation signal for full or partial acceptance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources are validated only at loading time using known laboratory devices, then resource validity checking is simple and quick, but resources may become invalid during the lab task schedule causing waste of samples and resources
Solution Approach 1:
The system performs preliminary validation by checking resource validity data against the complete lab task schedule at the time of resource loading. It calculates expected completion times for all tasks in the schedule and validates that resources remain valid throughout the entire scheduled period, not just at the start time. This preliminary check prevents subsequent validity issues during task execution.
Solution Approach 2:
The system generates a resource validation signal that provides feedback on whether the resource is valid for the scheduled tasks. This feedback mechanism allows the laboratory device to make informed decisions about resource allocation and task scheduling, preventing the use of resources that would become invalid during the scheduled period.
2Adaptability or versatility
If resources with different validity limits are combined for a lab task, then resource flexibility and adaptability increase, but valid resources may be wasted when combined with invalid resources
Solution Approach 1:
The system applies different validation criteria to different resources based on their specific validity characteristics. Each resource is evaluated individually against the task schedule requirements, allowing resources with different validity limits to be optimally matched to appropriate tasks. This ensures that each resource's specific quality characteristics are properly utilized without wasting valid resources in invalid combinations.
3Reliability
If the entire lab task schedule is invalidated due to a single invalid resource, then regulatory compliance is maintained, but valuable time and productivity are lost
Solution Approach 1:
The system segments the lab task schedule into individual tasks and evaluates resource validity for each task separately. When a resource is found to be invalid for certain tasks, only those specific tasks are affected rather than invalidating the entire schedule. This allows the schedule to be partially executed with valid resource-task assignments while excluding only the problematic combinations, thereby maintaining regulatory compliance without unnecessary time loss.

AI summary
A method and a laboratory device for validating a resource for a lab task schedule of a laboratory device, the lab task schedule including at least one lab task, the method including the steps of: identifying a resource upon being loaded onto the laboratory device; retrieving resource validity data (RVD) corresponding to the identified resource; retrieving an expected lab task completion time (CT) corresponding to each lab task of the lab task schedule; validating of the resource validity data (RVD) against the expected lab task completion time (CT) corresponding to one or more lab task(s) of the lab task schedule; and generating a resource validation signal indicative of a result of the validation of the resource validity data (RVD).
