Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample analyzers face inefficiencies when handling mixed batches of samples that require measurement by multiple units, as they often leave one measurement unit idle, reducing overall processing efficiency.
Innovation Solution
A sample analyzer with a controller that determines the optimal transport destination for each sample container based on the measurement items and operation states of multiple measurement units, ensuring that both units are utilized effectively by prioritizing samples that can be measured by either unit and optimizing the transport path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sample containers are transported sequentially from the head side of the rack to measurement units, then the transport process is simple and follows a fixed sequence, but the first measurement unit cannot be effectively used when only the second measurement unit can measure certain samples, reducing processing efficiency
Solution Approach 1:
The patent applies dynamics by making the transport destination flexible rather than fixed. The control unit dynamically determines which measurement unit (first or second) should receive each sample container based on real-time measurement capabilities and current state, allowing the system to adapt to different measurement requirements and optimize utilization of both measurement units
Solution Approach 2:
The patent changes the parameter of transport destination selection from a fixed sequential order to a dynamic decision based on measurement item compatibility. The control unit evaluates whether the first or second measurement unit can perform the required measurement and routes samples accordingly, changing the routing parameter based on measurement capability parameters
2Reliability
If all sample containers are transported to the second measurement unit for samples requiring unique measurement items, then measurement accuracy for specific items is ensured, but the first measurement unit remains idle, reducing overall system productivity
Solution Approach 1:
The patent applies universality by enabling both measurement units to be utilized for different sample types. The first measurement unit handles samples for which it is suitable, while the second measurement unit handles samples requiring its unique measurement capabilities. This multi-functional utilization ensures both units contribute to processing, improving overall productivity while maintaining measurement reliability
Solution Approach 2:
The patent segments the sample population into different groups based on measurement requirements. Samples are divided into those that can be measured by the first unit, those that can be measured by the second unit, and those that require the second unit's unique capabilities. This segmentation allows each measurement unit to operate independently on appropriate samples, maximizing utilization of both units

AI summary
The present invention is a sample analyzer including: a first and a second measurement unit configured to measure a sample accommodated in a sample container; a rack transport unit configured to transport each of a plurality of sample containers held in a sample rack to either the first or the second measurement unit; and a controller configured to acquire a measurement item information indicating a measurement item of each of samples accommodated in the plurality of sample containers held in the sample rack, determine a sample container to be a transport object and a measurement unit to be a transport destination of the sample container based on the acquired plurality of measurement item information, and control the rack transport unit to transport the sample container determined as the transport object to the measurement unit determined as the transport destination.
