Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sequential processing is used where one sample rack is fully processed before moving to the next, then processing accuracy is maintained, but processing time increases and throughput decreases

Engineering Contradiction:
Improvethroughput per unit timeVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The sensor unit performs preliminary identification of sample containers on the subsequent sample rack while the transport device is still transporting the current sample rack. This advance reading of container information allows the system to prepare for the next processing sequence without waiting for the current rack to be fully processed, thereby reducing idle time and improving throughput.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action by overlapping the transport operation of one sample rack with the identification operation of the next sample rack. The sensor unit and transport device work in parallel, ensuring that no component remains idle during the processing cycle, thus maximizing productivity without compromising accuracy.

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If separate operations are used for transporting sample racks and identifying sample containers, then operational simplicity is maintained, but processing efficiency decreases

Engineering Contradiction:
Improvesampling processing efficiencyVSAvoidsystem coordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The sensor unit is integrated with the transport device to form a combined system. The sensor unit is positioned on the transport device and moves together with it, allowing simultaneous transport and identification operations. This merging of functions reduces the number of separate operations required while improving processing efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transport device serves multiple functions: it transports sample racks to the sampling position and simultaneously supports the sensor unit for identifying sample containers on subsequent racks. This multi-functionality increases system efficiency without proportionally increasing device complexity.

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

AI summary

Provided is a transport mechanism that is disposed in a measuring device used for dispensing biological samples from sample containers configured to contain the biological samples to cuvettes so as to perform a predetermined measurement, and transports a sample rack configured to hold the sample containers. The transport mechanism includes: a table on which the sample rack is provided in plurality and sequentially placed; a container sensor unit configured to identify the sample containers held on the sample rack; and a transport device configured to transport the sample rack holding the sample container identified by the container sensor unit to a dispensing position at which the biological samples are dispensed. The container sensor unit is disposed in the transport device, so that the transport device transports a preceding sample rack while the container sensor unit identifies sample containers held on a subsequent sample rack.
